• IMPORTANT: Add any cold plunge water chemicals into the filter compartment.
• Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit the flow, or trip the high-limit thermostat which will turn off the entire cold plunge.

Avoiding the Risk of Hypothermia

Prolonged immersion in cold water can result in HYPOTHERMIA, a dangerous condition which occurs when the internal temperature of the body reaches a level several degrees below normal 98.6°F (37°C).

THE SYMPTOMS OF HYPOTHERMIA INCLUDE:

• Slow shallow breathing
• Slurred speech or mumbling
• Shivering
• Weak pulse
• Drowsiness
• Clumsiness
• Confusion
• Unconsciousness
• Possible bright red or cold skin (in children)

THE EFFECTS OF HYPOTHERMIA INCLUDE:

• Failure of respiratory system and heart
• Failure of the nervous system
• Failure to recognize the need and when to exit the cold Plunge unit
• Unawareness of impending hazard
• Physical inability to exit the cold plunge
• Fetal damage in pregnant woman
• Unconsciousness resulting in the danger of drowning.

[WARNING]: The use of alcohol, drugs, or medication can greatly increase the risk of fatal hypothermia in a cold plunge.

TO REDUCE THE RISK OF INJURY:

• The water in the cold plunge should not go below 40°F (4.5°C). Water temperatures between 40°F (4.5°C) and 80°F (26.5°C) are considered safe for a healthy adult. Lower water temperatures are not recommended for extended use (exceeding 5 minutes) and 2 minutes for younger children. Extended use can cause hyporthermia.

Avoiding the Risk of Skin Burns

• To reduce the risk of injury, before entering a cold plunge the user should measure the water temperature with an accurate thermometer.
• Test the water with your hand before entering the cold plunge to be sure it's comfortable.

Safety Sign

A SAFETY SIGN is included in the owner's package. The sign, which is required as a condition of Product Listing, should be permanently installed where it is visible to the users of the cold plunge.

Important Cold Plunge Instructions

The following contains important cold plunge information, and we strongly encourage you to read and apply them.

DO:

• Use and lock the cover when the cold plunge is not in use, whether it is empty or full.
• Follow the Cold plunge Care and Maintenance recommendations stated in this manual.
• Use only approved accessories and recommended cold plunge chemicals and cleaners.

SAVE THESE INSTRUCTIONS

DON'T:

• Do not leave the cold plunge exposed to the sun without water or the cover in place. Exposure to direct sunlight can cause solar distress of the shell material.
• Do not roll or slide the cold plunge on its side. This will damage the siding.
• Do not lift or drag the cover by using the cover lock straps; always lift or carry the cover by using the handles.
• Do not attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the cold plunge owner will void the warranty. If you have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are not able to resolve the problem, contact your authorized dealer. Many problems can easily be diagnosed over the telephone by an Authorized Service Technician.
• Do not spray water from a hose or any other device directly into the vents on the side and back panel. Doing so may cause severe damage to electrical components within the cold plunge unit and such damage would not be covered under the cold plunge warranty.

Cold Plunging for beginners involves the following:

1. Start with water that's between 50°F and 60°F (10°C and 16°C) if never cold plunged before.
2. Don't hesitate, submerge your entire body up to the jaw line.
3. Control your breathing and stay calm.
4. Get out when you start shivering (or before).
5. Gradually ease into building a tolerance to the frigid temperatures.
6. Consider doing a 15 - 30 second shot of cold water at the end of a shower to ease into it.

Installation

Planning a Location for Your Cold Plunge

Consider these things when determining where to place your cold plunge.

Safety First:

Make sure your cold plunge is positioned so access to the left side equipment compartment and back panel will not be blocked. Be certain your installation will meet all city and local safety codes and requirements.

Planned Use of Cold Plunge:

How you intend to use your cold plunge will help you determine where you should position the cold plunge. For example, will you use it more for recreational or therapeutic purposes? If your cold plunge is mainly for family recreation, leave plenty of room around it for activity and lawn furniture. You will use it more for relaxation and therapy, you'll probably want to create privacy around the cold plunge.

Privacy:

Think of your surroundings during all seasons to determine your best privacy options. Consider the view of your neighbors when you plan the location of your cold plunge.

Views:

Think about the direction you will be facing when sitting in your cold plunge. Do you have a special landscape you will find enjoyable? Perhaps there is an area that has a soothing breeze during the day or a lovely sunset in the evening.

Environment:

If you live in a climate with a snowy winter and hot summer, a place to change clothes or a house entry near the cold plunge is convenient. A warmer climate may require shade from the hot sun. Consider placement of trees, shrubs, patio cover or perhaps a gazebo structure to provide what you will need. Indoor installations require adequate ventilation. When the cold plunge is in use, small amounts of moisture may also be produced. This moisture can damage walls and ceiling surfaces over time. Special paint is available to resist moisture damage. Remember that cold plunge periodically requires drainage, so plan your environment accordingly. The heat pump 1½" (.64 cm) drain tube will need to be routed away from the cold plunge.

Keep Clean:

Prevent dirt and foliage from being tracked into your cold plunge by utilizing concrete for paths and access areas. Check the location of spill paths from gutters, trees, and shrubs.

Service Access:

Many people choose to install tile or custom wood around their cold plunge. If you are installing your cold plunge with custom decorative trimming, remember to allow for access to it for service. Should you need service, a technician may need to remove the cold plunge door panels. It is always best to design special installations so the cold plunge can still be moved, or lifted from the ground.

A Good Foundation:

Your new cold plunge needs a good solid foundation. The area your cold plunge sits on must be able to support the cold plunge, the water in it and those who use it. If the foundation is inadequate, it may shift or settle after the cold plunge is in place, causing stress to the shell or components. It is recommended to place the cold plunge on a 4" (10 cm) concrete pad with steel reinforcement bars crossed throughout the pad. NOTE: Do not shim your cold plunge in any manner, as this could cause the cabinet to warp, thereby voiding the warranty.

Indoor Installation:

Be aware of some special requirements if you place your cold plunge indoors. A floor drain is highly recommended.

• Water will need to exit through the front drain located on the lower left side area when draining cold plunge tub (this will require a garden hose to drain water out of the cold plunge and somewhere to drain water in to).
• A 1¼" (6.4 mm) drain tube from the collection pan 12 feet (3.7 m) long is coiled and located inside the equipment compartment. Remove this drain tube (place in cut out) and route to a drain or some type of collection unit. NOTE: Up to several gallons of water may exit this tube per day. External collection tray if used must not be higher than the tray holding the heat pump in place.
• Water will also accumulate around the cold plunge when exiting, so flooring materials must provide a good grip when wet.

NOTE: Proper drainage is essential to prevent water from running all over the floor and under the cold plunge unit. When building a new room for the cold plunge, it is recommended that a floor drain be installed.

It is best to provide plenty of ventilation to the cold plunge area. An architect can help to determine if more ventilation must be installed.

Ventilation:

The cold plunge unit has two ventilation locations. The backside panel must be at least 24" (61 cm) away from any wall or obstruction preventing airflow out of the cold plunge (72" [183 cm] is recommended for optimal performance). The side ventilation panel pulls air into the cold plunge and is also the main entrance into the equipment compartment, allow enough space 30" (76 cm) for someone to open and work inside if necessary.

NOTE: The backside panel once removed provides access to removing the heat pump (if necessary) for service.

Diagram Description: The diagram shows the cold plunge unit with labels pointing to: "Backside Ventilation", "Control Panel (Front)", and "Side Ventilation (Equipment Compartment)".

IMPORTANT: BECAUSE OF SHIPPING ORIENTATION, WAIT 24 HOURS TO FILL AND START YOUR COLD PLUNGE ONCE IT IS IN PLACE.

Start-Up & Fill-Up Instructions

IMPORTANT: BECAUSE OF SHIPPING ORIENTATION, WAIT 24 HOURS TO FILL AND START YOUR COLD PLUNGE ONCE IT IS IN PLACE FOR INITIAL STARTUP!

Position Power Cord

1. Open the Equipment compartment (side panel) door see page 7.
2. With the Equipment compartment open, uncoil the 15 foot (4.5 m) power cord.
3. Determine the distance of the power cord needed from the outlet to the cold plunge. DO NOT PLUG COLD PLUNGE IN UNTIL IT HAS BEEN FILLED WITH WATER!
4. Position the power cord inside the cut out.
5. Place any extra cord back into the equipment compartment.

Diagram Description: Image shows the inside of the equipment compartment with the power cord positioned in a cut-out area.

Position Drain Tube

With the Equipment compartment open:

1. Unravel the 1¼" (6.4 mm) drain tube 12 feet (3.7 m) long which is coiled and located inside the equipment compartment. This tube is attached to the collection pan underneath the large heat pump.
2. Position this drain tube (place in cut out, same as power cord above) and route to a drain or some type of collection unit out side of cold plunge if installed indoors. NOTE: Up to several gallons of water may exit this tube per day. External collection tray if used must not be higher than the tray holding the heat pump in place.
3. Place in any preferred location outside of the cold plunge if installed outdoors (use cut out). This drain tube can also be cut if too long.

Filling the Cold Plunge with Water

The following procedures should be followed on initial startup and whenever the cold plunge is drained for routine maintenance.

1. Clear all the debris from your cold plunge.
2. Verify Drain valve is closed and drain cap is attached and tight.
3. Remove Filter Lid.
4. Insert a garden hose into filter compartment to fill your cold plunge.
5. IMPORTANT: Do not fill with hot or softened water. If ambient temperatures are above 100° F (38°C) the cold plunge heat pump may not be able to start cooling the water when power is applied until the ambient temperature cools down below 100° F (38°C). NOTE: Direct sun may also warm up the inside of the equipment compartment making it hotter than the outside ambient temperature.
6. Under normal circumstances keep the water level just above the top of the upper equalizer fitting of the cold plunge. Failure to keep enough water in your cold plunge may result in damage to your system and invalidate your warranty. If your cold plunge filter is sucking in air causing the pump to cavitate, you need to add water!
7. Check the filter installation and make sure the filter is not loose.

IMPORTANT: Remember to change your water every three to six months.

Diagram Description: Image shows the filter compartment with labels pointing to "Filter Lid" and "Water Level".

5. After checking your cold plunge for leaks it is now time to adjust your cold plunge settings. Press the [Temp Up] or [Temp Down] button on your topside control panel until the display indicates your desired temperature is set.

Diagram Description: Image shows the inside of the equipment compartment with the power cord and drain tube in the cut-out area.

Adding Start-Up Chemicals

Water Chemistry Guidelines

Cold plunge water chemistry is ultimately the responsibility of the cold plunge owner. Improper water chemistry may result in costly repairs not covered under the cold plunge warranty. If unsure about any steps in the process below, please contact your local Dealer.

Initially, it is advisable to identify what minerals (e.g. iron) are present in the local source water. This will provide a better understanding of how to treat the water. Please follow the four steps below and be sure to achieve the correct levels in each area before moving onto the next step. ADD all chemicals into filter compartment.

STEP #1: MEASURE TOTAL ALKALINITY:

The Total Alkalinity is the amount of bicarbonates, carbonates, and hydroxides present in the cold plunge water. Proper total alkalinity is important for pH control. If the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The ideal range is between 40-120 parts per million (PPM). Reduce TA by using an Alkalinity Down/Decreaser (sodium bisulfate). Increased TA by adding an Alkalinity Up/Increaser (sodium bicarbonate or sodium hydrogen carbonate). These products should be added in small amounts - 5 ml at a time. After adding 5 ml, wait one half hour before re-measuring. Once the safe range of total alkalinity is established, proceed to the next step.

STEP #2: ESTABLISH PROPER PH LEVEL:

The recommended range for pH is between 7.2 and 7.8. Above 7.8, the water is too alkaline and can result in cloudy water, and scale formation on the shell and heater. To lower the pH use a pH Down/Decreaser (sodium bisulfate). Below 7.0 (considered neutral), the cold plunge water is too acidic and can damage the heating system. To increase pH, use a pH Up/Increaser (sodium hydrogen carbonate). Any pH Up or Down should be added one teaspoon at a time, waiting one-half hour between application and re-measuring.

STEP #3: DETERMINE CALCIUM HARDNESS:

It is important to bring the calcium reading to between 75-150 PPM. If the reading requires adjustment, it should now be corrected. If the water is too soft (a low reading) calcium hardness should be added to the water to increase the PPM reading. If the water is too hard (a high reading), it can be corrected by either: (A) a mixture of hard and soft water added to attain a reading in the safe range, or (B) addition of stain and scale control. If calcium hardness is a problem with the local source water (either too hard or too soft) a test kit, which measures calcium hardness, is essential.

STEP #4: SANITIZING:

After steps 1-3 are complete, the cold plunge must be sanitized using Chlorine (sodium dichlor). Add 2 teaspoons of Chlorine, and increase as necessary to reach a level of 3-5 ppm. Check and maintain this level weekly, and before and after using the cold plunge. IMPORTANT NOTE: A granulated sodium dichlor is highly recommended for sanitizing cold plunge water, granular bromine may also be used. Never use compressed sanitizers even with a floater. As with any other chemicals, the sanitizer should be introduced to the cold plunge in the filter compartment.

Cold Plunge Maintenance

Filter Cartridge Maintenance

Every month, the filter cartridge should be cleaned to remove the objects and particles that have lodged in the cartridge pleats. Using household water pressure and a garden hose with a pressurized nozzle, push water from inside to outside of the pleats, forcing all the trapped particles out.

NOTE: Never run your cold plunge without a filter cartridge!!! This will invalidate your warranty.

NOTE: Filter cartridges should be replaced every six to eight months or earlier when needed. Dirty filters can cause your cold plunge pump to burn out and will invalidate your warranty.

Filter Cartridge Removal and Cleaning Instructions

Cold plunge uses a screw in filter cartridge that is easily removed.

• Turn off the power to the cold plunge, (by unplugging the cold plunge unit).
• Remove filter lid (See Figure 1).
• Unscrew the filter cartridge counter clockwise and bring it out of the cold plunge (requires many turns) (See Figure 2).

• Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to remove all dirt and debris possible. Let filter dry and look for calcium deposits (scaling) or an oil film. If you find these, you will need to deep clean your filter cartridge with a “cold plunge filter cleaner" solution to break down and remove unwanted deposits and oils. (For longer filter life you should soak filter regularly).

CAUTION!

Always use proper eye protection when using chemicals, or high-pressure water. Read instructions on cleaning products and follow applicable safety and warning instructions listed on label.

CAUTION!

Never scrub the filter cartridge with a brush, as this will cause the filter to wear out and come apart. Never let the cold plunge pump run without a filter cartridge in the skimmer compartment. Running the cold plunge without a filter cartridge may permit debris to enter the cold plunge plumbing and void the warranty!

• Replace filter cartridge (insert and rotate clockwise to lock into position). DO NOT OVERTIGHTEN!
• Plug cold plunge back in to power up.

Diagram Description: Figure 1 shows the filter lid. Figure 2 shows the filter cartridge being removed.

Surface Care

Do not use solvents or abrasive cleaners to clean the cold plunge. Typically, a mild detergent and water will resolve cleaning issues.

Cover Care

The cover is made with a solution dyed polyester fabric and is an attractive, durable foam insulation product. Monthly cleaning is recommended to maintain its beauty and a longer fabric life.

To clean and condition the polyester cover:

1. Remove and gently lean against a wall or fence.
2. With a garden hose, spray the covers to loosen and rinse away dirt or debris.
3. Add four tablespoons of mild soap or mild dishwashing liquid with one gallon (4 liters) of lukewarm water. Clean using a soft bristle brush. Rinse thoroughly with cold water and air dry. IMPORTANT: Do not let the polyester dry with a soap film on it before it can be rinsed clean.
4. Scrub the cover's perimeter and side flaps. Rinse clean with cold water.
5. Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.

• Cleaning of the Quartz Tube is necessary whenever your UV system isn't functioning correctly. Contact your dealer for Quartz Tube cleaning. NOTE: UV-C lamp replacement could be done at the same time. The Quartz tube (6) cleaning will require the draining of the Cold Plunge unit.

UV-C Lamp Replacement

1. Unplug the Cold Plunge unit.

WARNING: Make sure UV-C lamp (20) is cool before removing. Latex gloves must be worn when installing a new lamp to prevent damage from the oils on your skin.

DANGER: Never look at the UV-C lamp (20) when on, this can cause severe eye damage or blindness.

2. Remove Equipment compartment door.
3. Remove enclosure cover (14) by removing the 4 screws (15).
4. Disconnect UV-C lamp connector (17) from ballast connector (16).
5. Slowly remove boot cover (18) and UV-C lamp (20) from quartz tube (6).

Replace new UV-C lamp as follows:

1. Slide the new UV-C lamp (20) back inside the quartz tube (6). Install boot cover (18) over compression nut (11).
2. Reconnect the UV-Clamp connector (17) to the ballast connector (16). Make sure the connector mates completely. Do not use force.
3. Reinstall the enclosure cover (14) with gasket (13 see below) and secure with screws (15).
4. Replace Equipment compartment door.
5. Plug the Cold Plunge back into outlet.

Draining or Winterizing

Every three to six months, depending upon the water condition, you need to renew your water.

CAUTION: READ THIS BEFORE DRAINING YOUR COLD PLUNGE!

• To prevent damage to the cold plunge's components, UNPLUG GFCI CORD OR TURN OFF SUBPANEL BREAKER BEFORE DRAINING. Do not power back up until your cold plunge has been refilled with water.
• There are certain precautions to keep in mind when draining your cold plunge. If it is extremely cold, and the cold plunge is outdoors, freezing could occur in the plumbing or the equipment.
• Do not leave the cold plunge's shell (inside surface) exposed to direct sunlight.

Draining Your Cold Plunge

• Unscrew and remove the drain cap.
• Attach hose bib to a garden hose and direct to an appropriate draining area, keeping the hose below the water line.
• Open Valve to drain.
• After your cold plunge is empty, clean the shell and filter cartridge. See "Cold Plunge Maintenance" section.
• After cleaning, remove garden hose, replace drain cap, close drain valve and push the hose bib back into the recess.
• Follow the “Fill up and Start-up Instructions” on page 12.

Diagram Description: Image shows the drain cap and hose connection.

Winterizing Your Cold Plunge

If you plan to store your cold plunge for the winter, you must also use a wet-vac to clean out the water lines to ensure they are free of any water. Water left in the lines might freeze and damage the lines and pump.

1. Drain your cold plunge.
2. It will be necessary to remove all water from the interior plumbing.
3. Remove the filter cartridge. Clean the filter cartridge and store in a dry place. Attach the vacuum hose to the vacuum side of the shop vac and thoroughly dry the filter compartment.
4. Using the shop vac, remove the water. NOTE: When removing the water from drain opening, you may notice suction coming from bottom of filter bucket. With the help of a second person, block off any suction from the filter suction fitting using a large rag or cloth. This will help pull out the water that is trapped deep inside the main line.
5. Thoroughly dry the cold plunge shell with a clean towel.
6. Using a funnel, pour Propylene glycol anti-freeze into the filter suction fitting and drain.

CAUTION: Use only Propylene glycol as your anti-freeze. This is non-toxic. NEVER use automobile anti-freeze since it is toxic.

IMPORTANT: Before using your cold plunge make sure to throughly dilute and remove any Propylene glycol first.

7. Replace the equipment compartment door and secure with screws.

NOTE: Damage caused by improper winterizing will not be covered under warranty. You may want to contact your local Dealer to properly winterize your cold plunge.

Troubleshooting Guide

In the event the cold plunge is not working the way it should, please first review all the installation and operating instructions in this manual and check the message on the panel display. If you are still not satisfied it is working properly, please follow the appropriate troubleshooting instructions.

CAUTION! WARNING! SHOCK HAZARD! No User Serviceable Parts.

Do not attempt service of the control box. Contact your local Dealer for assistance. Follow all owner's manual power connection instructions.

GFCI Tripping

The Ground Fault Circuit Interrupter (GFCI) is a safety device that is designed to detect as little as 5 milliamps (±1mA) of electrical current leakage to ground. WATKINS WELLNESS recommends that the GFCI be tested prior to each use to ensure it is functioning correctly. With the cold plunge connected to the power supply, push the yellow [Test] button. The cold plunge should stop operating and the GFCI power indicator will go out. Wait 30 seconds and then reset the GFCI by pushing the red [Reset] button. The GFCI power indicator will turn on, restoring power to the cold plunge. If the interrupter does not perform in this manner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the plug from the receptacle until the fault has been identified and corrected.

IMPORTANT: Failure to wait 30 seconds before resetting the GFCI may cause the Power indicator to blink. If this occurs, repeat the GFCI test procedure.

Never use the GFCI as a means to disconnect power to the spa (always unplug it). If the GFCI is tripped while plugged in, and a power outage occurs, when power returns the GFCI will automatically reset and power will flow to the cold plunge.

Cold Plunge Not Heating or Cooling

Should you notice the cold plunge is not heating or cooling while power is still available check the following:

1. Check both the Heat Pump and Circulation Pump icon on the control panel.
   • The Heat pump icon flashes ON/OFF when the heat pump is On. If there is a difference of 2° between the set temperature and actual temperature the heat pump should come on.
   • The Circulation pump icon should be On and solid at all times.
2. Make sure your set temperature is set to your desired temperature. Adjust if necessary.
3. If the cover to your cold plunge has been left off for a while this could cause the actual water temperature to be different from the set temperature. Place cover on top of cold plunge if it has been off for a while and allow some time for the actual water temperature to get to the set water temperature.
4. Should an error message show up on the screen, shut power off for 5 minutes and then power back on. If the error message comes back on see page 11 first then contact your local Dealer if needed.
