Using the Manual

This manual is intended to assist in the proper installation and maintenance of the WhisperKOOL cooling unit. To ensure the longevity of your cooling unit, the equipment should be installed correctly and have a proper care and maintenance schedule.

Please read and review this manual carefully and keep it for future reference.

What is the WhisperKOOL Cooling Unit?

The WhisperKOOL cooling unit is a specialized refrigeration unit designed for one purpose only: to maintain the optimal temperature and humidity levels conducive to the proper storage and aging of fine wines. It is a self-contained cooling unit designed to be used as a forced-air, through-the-wall unit.

How Does the WhisperKOOL Extreme Series Work?

The WhisperKOOL unit is specially designed to maintain optimal conditions for wine storage and aging. The unit is fully self-contained and can be installed through most walls. The unit is also capable of a more flexible ducted application, which allows the unit to be placed in an indoor remote site, resulting in a quiet airflow. The standard through-the-wall and ducted units are temperature-controlled via a bottle probe.
NOTE: The remote unit comes standard with a 50-foot bottle probe. Additional lengths are available from WhisperKOOL.

Temperature Setting

The WhisperKOOL cooling unit can be set at any temperature within the acceptable wine-aging range of 50–67°F. It is designed to create a differential of up to 55°F between the cellar and the ambient temperature (as long as the space to which the unit is exhausted does not exceed 110˚F).

BEFORE YOU START

Inspect the unit before installation. If damage is found, please contact your distributor or WhisperKOOL Customer Service at 1-800-343-9463.
The unit should remain in an upright position for 24 hours before operation.

The WhisperKOOL unit requires a dedicated 115V, 20-amp circuit. Use a surge protector with the WhisperKOOL unit. Do not use a GFI (ground fault interrupter) line.
The unit is designed to gently cool down the temperature of the cellar over time by cycling cooler and cooler air throughout. Test the unit before installation.

You are REQUIRED to install a drain line to remove condensation from the unit.
The WhisperKOOL unit is intended for use in properly designed and constructed wine cellars. Hire a professional wine storage consultant with a valid contractor’s license to build your wine cellar.

Never try to open the WhisperKOOL unit, repair it yourself, or use a service company without WhisperKOOL’s authorization. This will void your warranty. If you encounter a problem with your WhisperKOOL unit, please refer to the Troubleshooting Guide. If you have any further questions, or concerns, or need assistance, please contact WhisperKOOL Customer Service at 1-800-343-9463. Please be sure all testing has been completed before contacting Customer Service. Please have your results ready for your representative.

FAN SPEED

Fan speed selection is determined by the amount of heat that needs to be removed from the cellar and the type of installation (through-the-wall or fully ducted). Fan speed selection is based on the cellar size, insulation factor, door seal, and desired wine temperature. When initially installing the unit, set the fan speed to the High setting to quickly chill the wine cellar. Once the wine cellar reaches the desired temperature, a lower fan speed may be selected. If the outdoor temperature rises above 90°F, (when exhausting to the outdoors) a higher fan speed may be required.

* Sizing the Unit to the Room
The specification chart will provide information on the unit’s cooling capacity. There are circumstances in which a cellar design may require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem adequate but do not offer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

PREPARING THE WINE CELLAR

The performance and life of your system are contingent upon the steps you take in preparing the wine cellar. Improperly preparing your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and other negative side effects.
It is highly recommended that you obtain the assistance of a wine storage professional. Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build well-insulated, beautiful, and protective wine cellars.
WhisperKOOL has put together some useful tips to assist in the installation process. Our recommendations are meant to act as a guide in the process of building a proper enclosure.

Your intended location may have specific needs which we do not address.

Wall & Ceiling Framing

Build wine cellar walls using standard 2×4 or 2×6 boards and ceiling joists without violating local or state codes in your area. As a general rule, the thicker the walls and the higher the insulation value, the more consistent your cellar temperature will be.

Insulation

Insulation is REQUIRED to properly use WhisperKOOL products. All walls and ceilings must be insulated to keep the cellar temperature as consistent as possible during the summer and winter months. Standard fiberglass or rigid foam insulation is normally used in cellar construction; in some cases, “blown-in” insulation is used.
The R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation. The higher the R-value, the more resistant the insulation is to conducting heat, and the more consistent your wine cellar’s temperature will be. Using higher R-values in insulation will lower your operating costs and WhisperKOOL unit run time. (R-13 is the recommended minimum; R-19 is preferred for interior cellar walls, and R-30 for ceilings and exterior walls.)

Vapor Barrier

Water vapor creates its pressure, separate from the ambient air pressure, and will intrude into colder/drier areas. A vapor barrier is REQUIRED to prevent the intrusion of water vapor and maintain the correct cellar temperature and humidity. It is recommended that 6-millimeter plastic sheeting be applied to the warm side of the cellar walls. The vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the outside, then the plastic must be applied from within the cellar. The most common method is to wrap the entire interior, leaving the plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls and ceiling must be wrapped in plastic for a complete vapor barrier.
In areas of high humidity, such as the Southern and Gulf States, the vapor barrier will prevent infiltration of warm moist air. The moist air can cause mold to form, and standing water in drain pans promotes microbial and fungal growth that causes unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that portion of the unit.

Note: High humidity significantly increases the heat load on the cooling system.
Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will cause a moisture leak and must be sealed. The electric conduit is a “duct” for vapor to travel in. The conduit should be caulked and sealed on the warm air end.

Mounting the Unit

NOTE: Do not attempt to mount the unit in a wall recess or attempt to camouflage or cover the unit with any sort of aftermarket grille, accessory, etc. This can restrict airflow, prevent the unit from working properly, and void the warranty. Please feel free to call WhisperKOOL Customer Service with any questions or concerns regarding installation requirements.

Door and Door Seal

An exterior-grade (13/4”) door must be installed as a cellar door. It is very important that weather stripping be attached to all four sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have a very good seal to keep the cool cellar air from escaping out of the cellar. If the cellar door does not seal properly, the unit will run continuously. In cases where glass doors are used and the room size is close to the recommended unit size, the next larger size WhisperKOOL should be used. This will compensate for the insulation loss due to the lower insulation rating of glass.

Ventilation

The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit operates and cools, a greater amount of heat is generated on the exhaust side of the unit. Adequate ventilation is required to dissipate heat away from the unit. If ventilation is inadequate, the exhaust will heat the area or room and adversely affect the unit’s ability to cool. In some cases, it may be advisable to install a vent fan to dissipate heat from within the exhaust area.
However, you must have a fresh air inlet as well. If your unit requires ducting, please contact WhisperKOOL to obtain a specially designed ducting plenum for the unit.

Using any other ducting system will void the warranty.

Note: If you are unsure whether you have adequate ventilation in your install location, please contact us to assess your specific installation at support@whisperkool.com or 1-800-343-9463.

Ambient Temperature Factor

The cooling unit can cool a wine cellar efficiently to 55°F as long as the ambient temperature of the area that it is exhausting to does not exceed 110°F.
Therefore, you want to exhaust the unit in a room that will not exceed 110°F. Without proper heat dissipation, the unit will not have the capacity to keep the wine at a desirable 55°F.

WARNING! Allowing your unit to operate in high ambient temperatures for extended periods will greatly decrease the life of your unit and void your warranty.

PREPARING THE UNIT FOR INSTALLATION

The WhisperKOOL Unit requires a dedicated 115V, 20-amp circuit. The unit draws a large amount of amps during its initial startup. By designating a dedicated circuit breaker, you will guarantee the unit has enough power to run effectively. Contact an electrician for assistance with the installation of this dedicated electrical circuit.

The unit must sit upright for 24 hours before installation. To prepare the unit for installation:

Remove the unit from the box.
Match the electrical outlet to the plug provided on the WhisperKOOL unit.

Provide a dedicated circuit and wiring for the unit (see above).
Provide a weatherproof plug for units connected outside.
Power surges and spikes can damage sensitive electrical equipment. WhisperKOOL recommends plugging the unit into a surge protector or power conditioner to protect your system. As outlined in our terms and conditions, power surges and spikes are not covered under warranty.

We recommend that you do not use a GFI (ground fault interrupter) with this product.
The unit is equipped with two power inlets. One is located on the right side of the unit (inside of the cellar), and the other is located on the rear of the unit (outside of the cellar). Use the selector switch located on the right side of the unit to select which power inlet you would like to use. If you would like to plug the unit into a socket outside of the cellar, set the selector switch to the rear. If you would like to plug the unit into a socket inside of the cellar, set the selector switch to the front position. When placed in either position, power can only enter the unit utilizing the power inlet you’ve selected.
In case the unit should lose power, check the home/main circuit breaker. If the unit does not respond properly, refer to the Troubleshooting Guide.

PREPARING THE INSTALLATION LOCATION

Locate the desired installation location (no more than 18 inches from the ceiling).

Using a stud finder, locate the studs on either side of the center point and mark them with vertical lines.
Using a level and a pencil, mark a horizontal line on the wall between the two studs, no less than 11/2 inches and no more than 18 inches from the ceiling.
Using a ruler or measuring tape, measure 16 inches down (3500 & 5000ti) or 22.25 inches down (8000 ti), and mark another horizontal line parallel to the first one.

Using a saw, cut along the uppermost horizontal line until your saw reaches the stud.
Turn the saw around, insert it into the cut that has just been made, and cut toward the opposite stud so that there is a clean horizontal cut between the two studs. Be careful not to cut into the studs themselves.
Make the second horizontal cut from stud to stud on the line 16 inches below the first cut.

Once the horizontal lines have been cut, make vertical cuts using the inside edge of the studs as a guide. Once both vertical cuts have been made, there should be a rectangular hole in the sheetrock. Make the same hole on the other side of the wall.
Using a nail, mark all four corners of the first hole by making nail holes through the sheetrock. Connect the holes with a pencil mark and cut on the other side of the wall.
Sheetrock alone cannot support the weight of a 96-lb cooling unit. Therefore, it is necessary to frame the hole that has just been cut with upper and lower supports.

These supports also provide solid material for the mounting bracket screws.
Using two 2x4s (14.5 inches in length) and eight 6d nails, secure the upper and lower supports to the right and left studs, just inside the sheetrock. Make sure that the internal height remains at 16 inches (3500 & 5000ti) or 22.25 inches (8000 ti) so that the
WhisperKOOL unit will fit snugly through the framed cut-out.

PREPARING THE UNIT FOR INSTALLATION

A sturdy single-piece mounting bracket is used to frame the installation location and secure the unit to the wall studs. The bracket has been designed to hold the unit at a two-degree (2°) angle. This helps project air into the space and aids in condensation drainage.

Applying Insulation Tape

Locate the six-foot piece of black foam tape included with the unit.
Align one end of the foam tape with the upper left corner of the rear side of the mounting bracket. Stretch the tape across the rear of the bracket and cut the tape at the opposite edge. Peel off the white paper backing and attach the cut piece of foam tape to the top rear side of the mounting bracket. Follow the same procedure to place a piece of tape on the bottom edge of the mounting bracket.

Place the remaining piece of foam tape on one side of the mounting bracket (spanning the distance between the pieces of tape on the top and bottom edges of the mounting bracket), then cut, remove the paper backing, and secure. Do the same on the opposite side of the bracket. Discard any excess. The foam tape will create a tight seal between the bracket and the wall.

Mounting Bracket Installation

Select your desired bracket mounting location (see diagram below). This location determines the depth of the installation. For example, position #1 keeps most of the unit out of the cellar while position #4 sets the back of the unit near flush with the exterior wall. Slide bracket onto the unit. Ensure that the TOP label on the bracket and the unit mounting flanges are towards the back. Use the supplied 1/2” pan-head screws to fasten the bracket to the unit. you must use screws no longer than 1/2” in length. If you are installing through an exterior wall, please review the specific instructions on exterior grill installation.

OPTIONAL EXTERIOR GRILLE

The exterior grille is required on all installations where the exhaust side of the unit is exposed to the outdoors (i.e., rain and other adverse weather conditions).

Non-Flush Installation

Install the unit according to the standard through-the-wall procedure. After the unit is installed, place the exterior grille over the exhaust side filter grille and line up the screw holes on the top, bottom, and sides. Use the supplied 1/2″ pan-head screws to fasten the grille to the unit.

Flush Installation
This installation is slightly different because you are utilizing the same holes for both the mounting bracket and exterior grille.

Slide the mounting bracket onto the unit followed by the exterior grille, and bring the two pieces together by sliding the exterior grille over the mounting bracket side flanges.
Align the two top screw holes of the exterior grill with the top screw locations on the unit. Use the supplied 1/2″ pan-head screws to fasten the grille.
Repeat Step 2 on the bottom of the unit.

Use the supplied 1/2″ pan-head screws to fasten the grille and bracket to the unit ensuring the bracket stays perpendicular/ square.
Continue through the wall installation.

You are required to use the 1/2” pan-head screws provided. Do not drill holes into the unit.

INSTALLING THE UNIT

Slide the unit from the outside wall into your wine cellar with the outer flange flush with the wall. Secure the flange to the wall using the pre-drilled holes. The 13/4″ screws should penetrate the studs as well as the upper and lower supports to provide adequate support for the WhisperKOOL unit (see illustration). Seal all cracks and gaps around the WhisperKOOL Extreme unit with an airtight sealant or caulking to prevent air leakage.
Note: If you use decorative molding, it should be attached to the walls and never to the cooling unit itself. The molding itself should be removable in case the unit needs servicing.

CONDENSATION DRAIN LINE

The condensation drain line tube is used to drain excess condensation from the unit to a proper discharge location. The drain line tube must be properly connected to prevent leakage and other problems associated with excess condensation. Failure to use the condensation drain line tube will void the warranty on the unit. All units come with a drain line for additional removal of excessive condensate. It is mandatory to install the drain line with a “tee” fitting. During operation, the cooling unit will strip excess water from the air to maintain the proper level of humidity within the cellar. However, in extreme humidity, additional condensate will be removed. The drain line will prevent overflow and leaking by allowing for the discharge of the additional condensate. To prevent mold from growing, allow the drain line to hang above the water line.

Extreme Drain Line Installation

Wrap tee with Teflon tape one or two turns clockwise.
Next, thread the barbed tee into the drain port and rotate until tight. Make sure the barbed parts of the tee are vertical.

Next, attach the piece of 1/2″ ID clear plastic tubing to the lower barb of the tee.
Every six weeks, disconnect the drain line from the tee. Remove the tee from the rear drain port and clean it. Then use the supplied drain line brush to clean the interior drain line. Use the drain line access door to drop a pan tab into the drip tray to prevent the buildup of microbial growth.

LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE)

WhisperKOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating bottle probe contains a sensor that communicates back and forth with the thermostat. This results in a consistent temperature setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity. By measuring the liquid temperature rather than air, the unit will operate 75–80% of the time.

Setting up the Bottle Probe

Locate an empty wine bottle.

Fill it 75% full with room-temperature tap water.
Place the bottle probe securely into the bottle as seen in Figure 1.
Place the bottle off to the side of the unit in your wine cellar, with the probe level.

To ensure a consistent temperature, place the bottle probe approximately three (3) feet away from the air output and not in the flow of the air.
Connect the opposite end of the bottle probe wire to the circular connector on the front of the unit marked “BOTTLE PROBE.” Twist the connector clockwise to lock it in place as seen in Figure 2.

It is recommended that the bottle be placed in a central location in your wine cellar. Avoid pulling too much on the probe cord. It may become disconnected, resulting in limited functionality of the unit.
Note: The thermostat can be set between 50-67°F.
Remember: The WhisperKOOL unit operates based on the temperature of the water. Do not be misled by thermostats that read air temperature. The air temperature in the cellar will be cooler than the liquid temperature of the wine while it is reaching its optimum balanced temperature.

MULTI-SPEED FAN CONTROL

Designed for wine cellars up to 1000 and 2000 cubic feet, the Extreme 3500ti, 5000ti, and 8000ti feature multi-speed fans. These fans have a high setting for maximum performance in high-temperature (+110°F) environments and a low setting for super-quiet operation.

Fan Speed Selector Switch (Low/Med/High)

The cooling unit fans operate on three-speed settings: Low, Medium, and High. For optimum sound and energy efficiency, select the lowest fan speed that will maintain the desired cellar temperature. If the relative humidity is low, a higher fan speed will cause less moisture to be removed during cooling. High speed is recommended for initial cellar cool-down, extreme temperature conditions, and ducted installations.
Fan speed selection is determined by the amount of heat that needs to be removed from the cellar and the type of installation (through-the-wall or fully ducted). Fan speed selection is based on cellar size, insulation ratings, door seals, and the desired wine temperature. When initially installing the unit, set the fan speed to the High setting to quickly cool down the cellar.

Once the wine cellar reaches the desired temperature, a lower fan speed may be selected. If the outdoor temperature rises above 90°F (when exhausting to the outdoors), a higher fan speed may be required.

SYSTEM OPERATION

Initial Start-Up
- When power is applied to the unit, the snowflake symbol will be displayed (if the unit is calling for cooling). There may be a delay of up to 60 seconds before the evaporator fan turns on. When the evaporator fan is activated, the fan symbol will display.
- APST (Advance Product Safety Technology) is a temperature control feature for the evaporator fan that comes standard with all WhisperKOOL units. APST ensures that in the possible event of a cooling deficiency, the heat from the indoor fan will not raise the temperature of the wine cellar, which could otherwise hurt the wine-aging process.
Setpoint
- The setpoint is set at the factory (WhisperKOOL) to 55°F. It can be adjusted by the customer between 50–67°F in one-degree increments.
Humidity Features
- The Fon (“fan on”) function is an adjustable feature that allows the customer the convenience of reintroducing some of the humidity removed by the fan coil during the cooling process. When the bottle probe has reached the setpoint (all units are shipped with the setpoint of 55°F and a differential of 1°), the compressor and the condenser fan will turn off, but the indoor fan will continue to run for about 5 minutes to reintroduce any moisture from the evaporator coil. All units come with this feature turned off. If low humidity is a problem, increasing the “fan on” time will raise the humidity level.
Anti-Short Cycle
- The Anti-Short Cycle ensures that the compressor will remain off for three minutes after the unit has reached the setpoint to allow the pressure in the refrigeration unit to equalize prior to starting the compressor.
Anti-Frost Cycle (defrost)
- When the evaporator probe senses a temperature of 26°F for five minutes, the unit will go into an Anti-Frost Cycle. This will shut down the compressor and allow the evaporator and condenser fans to run to evaporate any frost accumulation on the coil. The compressor will remain off until the evaporator coil reaches 40°F, or for a maximum of ten minutes. The unit will then return to normal operation.
Bottle Probe Failure Protection
- If a bottle probe should fail, the APST (Advance Product Safety Technology) will automatically transition the compressor to a pre-determined time cycle (based on detailed laboratory testing), which will ensure that the product is kept within a safe temperature range.
Display
- The bottle probe temperature is displayed by default. “Def” is displayed during Anti-Frost. The air sensing probe and evaporator probe temperatures can be accessed by pushing the SET button and scrolling through “PB1” (bottle probe), and “PB2” (evaporator probe).
Safety Features
- Once the compressor relay is de-energized the controller must wait five minutes before reenergizing the relay. This prevents the compressor from repeatedly turning off and on. If the unit is calling for cooling during this time, the compressor symbol will blink, indicating that cooling is needed but the control is waiting for the Anti-Short Cycle delay.
- In the event of a faulty bottle probe, the compressor will cycle off for 10 minutes and on for 40 minutes. “P1” will be displayed on the screen.
Alarms
- See Alarm Codes in the Controller Functions chart.

CONTROLLER FUNCTIONS

CPSM (CUSTOMER PREFERENCE SELECTION MODE)
Press and hold the SET and DOWN ARROW buttons for 10–15 seconds to enter the CPSM menu.

Fon Humidity Management/ Enhancement	The “fan on” setting is preset at the factory to zero minutes, which should provide adequate relative humidity for the cellar. Increasing the amount of “fan on” time will increase the Humidity Enhancement (%RH). Adjustments should be made in increments of 5, with a maximum of 15 and a minimum of 0. After any adjustment to Humidity Enhancement, you should wait a minimum of three days before making any additional adjustments. This will allow the cellar sufficient time to acclimate to the new setting.
FOF	The “fan off” time is normally set to 15 minutes. This parameter should not be adjusted, as it simply provides an OFF cycle time for the fan during the compressor’s OFF cycle.
CCS	Cellar Pre-Chill Setpoint. This parameter is set at 52°F but can be adjusted to a setpoint between 50–67°F.
CCt	Cellar Pre-Chill Duration. This parameter is set to 6 hours but can be adjusted to a setpoint between 0–23.5 hours.
Con/Cof	Compressor On time (Con) and Off time (Cof) with a P1 Alarm. These parameters are set at Con 40 min/Cof 10 min. In the event of a P1 Alarm, the compressor/refrigeration system automatically starts a predetermined ON/OFF cycle, which is controlled by the Con and Cof parameters. These parameters can be adjusted to maintain the desired bottle temperature.
HES	Differential for Energy Reduction. During the Energy Reduction mode, this parameter is set at 4°F above the setpoint. A decrease in this setting will lower the setpoint and an increase in this feature will raise the setpoint.

MAINTENANCE SCHEDULE

Monthly

1. Check for unusual noise or vibration

2. Check the drain line to see if it is above the waterline (when draining into a vessel)

Every Six Weeks

Using the supplied drain line brush, clean the interior drain line leading from the drip tray and drop a pan tab into the drip tray (see illustration below for more details).

Annually

1. Use a vacuum with a brush attachment to clean coils; be careful not to crush coil fins

2. Inspect for corrosion

3. Check wiring connections and integrity of cords

4. Pour a 50/50 bleach solution into the external drain line every spring

Pan tabs kill bacteria and related odors, remove sludge and scale, and help prevent water damage caused by condensate overflow. They are non-corrosive and easy to install. Simply use the access door to drop a pan tab into the drip tray every six weeks.
WARNING: Keep pan tabs out of reach of children. They contain quaternary ammonium chloride and can cause skin and eye irritation. They are harmful or fatal if ingested. Wear protective gloves when handling pan tabs.
Wash hands thoroughly after handling.
If pan tabs make contact with the eyes, rinse cautiously with water for several minutes. In case of an emergency, call 1-800-255-3924 (24 hours).

ACCESSORIES FOR COOLING UNITS

WhisperKOOL offers accessories to enhance and customize your wine cooling unit.

Exterior Grille

Protects the unit from the weather elements when placed on the exhaust side.
Small Exterior Grille (used for Extreme 3500ti & 5000ti)
Large Exterior Grille (used for Extreme 8000ti)

Condensate Pump Kit

The condensate pump kit is designed as an automatic condensate removal pump for water dripping out of our cooling units’ drain line. The pump is controlled by a float/switch mechanism that turns the pump on when approximately 2¼” of water collects in the tank, and automatically switches off when the tank drains to approximately 1¼”. The condensate pump kit allows the excess condensate to be pumped up to 20 feet away from the unit.

Extreme Ducting Kit

This kit allows either side of the unit to be ducted. Duct the cold air through a vent into the cellar, and duct the hot exhaust air out of the home. This option allows for total installation flexibility.
Note: Flex or rigid ductwork is not included.
Accessories can be purchased at www.whisperkool.com.

Product Installation Requirements:
- A. Before installing a WhisperKOOL Product, the End User must read the WhisperKOOL Owner’s Manual and thereafter the End User must follow the required installation, use, and maintenance procedures set forth by WhisperKOOL in WhisperKOOL’s Owner’s Manual. The Owner’s Manual is shipped with each Product and if another copy is needed, replacement copies can be downloaded from WhisperKOOL’s website (www.whisperkool.com) or by contacting WhisperKOOL directly for a new copy of the Owner’s Manual.
- B. It is highly recommended that the End User obtain the assistance of a wine storage professional.
- C. Failing to address all of the variables associated with proper installation will cause the Product to operate incorrectly and limit both the Product’s ability to cool and the longevity of the Product itself.
- D. The End User is responsible for all risks and costs of installation of the Product, including but not limited to all labor costs as well as the cost of any additional parts required for the proper and complete installation of the Product. The End User is responsible for all risks and costs of removing the Product if limited warranty work is required.
- E. The Product cannot operate at its optimum capacity if airflow is constricted by ducting or venting the exhaust side of the Product into a location with inadequate ventilation.
Maintenance Requirements
- It is the End User’s responsibility to clean off any accumulated dust, lint, or other debris from the front and rear intake grills. Failure to do this regularly will restrict the airflow and may affect the Product’s ability to function properly. Periodically cleaning the Product’s vents will help ensure maximum cooling efficiency. The drain line tube must also be checked and kept clean and free of debris and mold to maintain proper performance.
- Mold is a natural living organism in the environment. It exists in the air in the form of microscopic spores that move in and out of buildings through doors, windows, vents, HVAC systems, and anywhere else that air enters. Once it is discovered, mold must be addressed quickly and appropriately. Delayed or improper treatment of mold issues can result in costly and reoccurring repairs. If the End User suspects a mold problem, it is always best to hire a qualified and experienced mold remediation specialist.
Additional End User Costs And Responsibilities
- The following items are not covered under any warranty and are the sole responsibility of the End User:
  - A. End Users should satisfy themselves that the Product they are purchasing is suitable for their particular needs and requirements, and thus no responsibility will be placed with WhisperKOOL for the End User’s decisions in this regard.
  - B. It is the End User’s responsibility to secure haven/storage for ANY AND ALL items that are being kept and stored in the End User’s wine cellar, including any Product. WhisperKOOL takes no responsibility for the safety and preservation of the aforementioned items if the environment becomes unsuitable to maintain a proper storage environment.
  - C. End User is responsible for initial installation costs, including, but not limited to, labor costs and the cost of any additional parts necessary to complete the installation.
  - D. End User is responsible for all costs incurred for the installation and/or removal of the Product, or any part thereof unless such cost has been agreed by WhisperKOOL to be a warranty repair before the work being performed.
Sales and Use Tax
- WhisperKOOL only collects California sales tax for orders shipped within the State of California. WhisperKOOL does not collect sales tax for orders shipped to other states. However, the Purchaser and the End User may be liable to the taxing authority in their state for sales tax and/or use tax on the Product. The Purchaser and the End User should each check with their state’s taxing authority for sales and use tax regulations.
