OWNER'S GUIDE & SERVICE MANUAL

Unpacking Your Appliance

⚠️ WARNING: EXCESSIVE WEIGHT HAZARD Use two or more people to move product. Failure to do so can result in personal injury.

Your appliance has been packed for shipment with all parts that could be damaged by movement securely fastened. Remove internal packing materials and any tape holding internal components in place. The owner's manual is shipped inside the product in a plastic bag along with the warranty registration card and other accessory items.

ℹ️ Important: Keep your carton and packaging until your appliance has been thoroughly inspected and found to be in good condition. If there is damage, the packaging will be needed as proof of damage in transit. Afterwards, please dispose of all items responsibly.

⚠️ WARNING: If the appliance was shipped, handled or stored in other than an upright position for any period of time, allow the appliance to sit upright for a period of at least 24 hours before plugging in. This will assure oil returns to the compressor. Plugging the appliance in immediately may cause damage to internal parts.

⚠️ WARNING: Help Prevent Tragedies. Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators are still dangerous, even if they sit outside for "just a few hours". If you are getting rid of your old refrigerator, please follow the instructions below to help prevent accidents:

• Take off the doors or remove the drawers.
• Leave the shelves in place so children may not easily climb inside.

⚠️ WARNING: Dispose of the plastic bags which can be a suffocation hazard.

ℹ️ Note to Customer: This merchandise was carefully packed and thoroughly inspected before leaving our plant. Responsibility for its safe delivery was assumed by the retailer upon acceptance of the shipment. Claims for loss or damage sustained in transit must be made to the retailer.

ℹ️ NOTE: DO NOT RETURN DAMAGED MERCHANDISE TO THE MANUFACTURER - FILE THE CLAIM WITH THE RETAILER.

Electrical Connection

❌ Do not remove ground prong.

A grounded 115 volt, 15 amp dedicated circuit is required. This product is factory equipped with a power supply cord that has a three-pronged, grounded plug. It must be plugged into a mating grounding type receptacle in accordance with the National Electrical Code and applicable local codes and ordinances. If the circuit does not have a grounding type receptacle, it is the responsibility and obligation of the customer to provide the proper power supply. The third-ground prong should not, under any circumstances, be cut or removed.

ℹ️ NOTE: Ground Fault Circuit Interrupters (GFCI) are prone to nuisance tripping which will cause the appliance to shut down. GFCI's are generally not used on circuits with power equipment that must run unattended for long periods of time, unless required to meet local building codes and ordinances.

⚠️ WARNING: Electrical Shock Hazard

• Do not use an extension cord with this appliance. They can be hazardous and can degrade product performance.
• This appliance should not, under any circumstances, be installed to an un-grounded electrical supply. Do not remove the grounding prong from the power cord.
• Do not use an adapter.
• Do not splash or spray water from a hose on the appliance. Doing so may cause an electrical shock, which may result in severe injury or death.

Cutout and Product Dimensions

Rough-in Opening Dimensions:

• Dimension "A": 24" (61 cm)
• Dimension "B": 34" to 35" (85.7 cm to 88.3 cm)
• Dimension "C": 24" (61 cm)
• Dimension "D": 23 7/8" (60.7 cm)

Cabinet Dimensions:

• Dimension "E": 33 3/4" to 34 3/4" (86.4 cm to 88.9 cm)
• Dimension "F": 23 3/4" (60.3 cm)
• Dimension "G": 26 1/4" (66.7 cm)
• Dimension "H": 47 3/8" (120.4 cm)
• Dimension "J": 26 3/8" (67.1 cm)

Diagrams illustrate these dimensions, showing the relationship between the rough-in opening and the appliance cabinet. A solid door is shown for reference.

If necessary, to gain clearance inside the rough-in opening, a hole can be cut through the adjacent cabinet and the power cord routed through this hole to a power outlet. Another way to increase the available opening depth is to recess the power outlet into the rear wall to gain the thickness of the power cord plug. Not all recessed outlet boxes will work for this application as they are too narrow, but a recessed outlet box equivalent to Arlington #DVFR1W is recommended for this application.

Product Data

Diagrams show product dimensions with minimum clearances. A minimum rough-in opening is required to be larger than the adjusted height of the cabinet. A grounded 15 amp dedicated circuit is required. Follow all local building codes when installing electrical and appliance.

Installing Your Appliance

Select Location: The proper location will ensure peak performance. We recommend a location out of direct sunlight and away from heat sources. The recommended installation location temperature range is from 55 to 100°F (13 to 38°C).

Cabinet Clearance: Ventilation is required from the bottom front of the appliance. Keep this area open and clear of any obstructions. Adjacent cabinets and countertops can be installed around the appliance as long as the front grille remains unobstructed. All Marvel Outdoor models with articulated hinges are intended for built-in applications only.

⚠️ WARNING: An optional stacking kit, for 24" wide models, is required to stack products. Failure to use a stacking kit could result in personal injury. Contact your dealer or Marvel customer service at 616-754-5601 to order. For safety concerns, 15" wide models should not be stacked.

⚠️ CAUTION: Do not obstruct the front grille. The openings within the front grille allow air to flow through the condenser heat exchanger. Restrictions to this air flow will result in increased energy usage and loss of cooling capacity. For this reason, it is important this area is not obstructed and the grille openings are kept clean. Marvel does not recommend the use of a custom-made grille as air flow may be restricted.

Leveling Legs: Adjustable legs at the front and rear corners of the appliance should be set so the unit is firmly positioned on the floor and level from side to side and front to back. The overall height may be adjusted higher (by turning the leveling leg out, counter-clockwise) and lower (by turning the leveling leg in, clockwise). To adjust, lean the appliance back with assistance to access front legs. Adjust legs by turning. Repeat for rear legs by tilting the appliance forward with caution. Check for levelness on a solid surface and adjust accordingly. The front grille screws may be loosened and the grille adjusted to the desired height. Tighten screws when adjustment is complete.

Diagrams show the location of front and rear leveling legs and the front grille screws.

Side-by-Side & Stacking Installations

Side-by-Side Installation: Units must operate from separate, properly grounded electrical receptacles placed according to each unit's electrical requirements.

To ensure unobstructed door swing (opening both doors at the same time), 1/4" (6.4 mm) of space needs to be maintained between the units.

Stainless steel models which include the standard stainless handle will require 4-9/16" (116 mm) to allow both doors to open to 90° at the same time.

Diagrams (Figures 10-13) illustrate required clearances:

• Hinge-by-Hinge Installation (Mullion): When installing two units hinge-by-hinge, 13/16" (22 mm) is required for integrated models. Additional space may be needed for any knobs, pulls or handles installed.
• Hinge-by-Wall Installation: When installing a unit hinge-by-wall or adjacent cabinetry, 7/16" (11mm) is required for integrated models. Additional space may be needed for any knobs, pulls or handles installed.

Energy Saving Tips

The following suggestions will minimize the cost of operating your refrigeration appliance:

1. Do not install your appliance next to a hot appliance (cooker, dishwasher, etc.), heating air duct, or other heat sources.
2. Install product out of direct sunlight.
3. Ensure the front grille vents at the front of the appliance beneath the door are not obstructed and kept clean to allow ventilation for the refrigeration system to expel heat.
4. Plug your appliance into a dedicated power circuit (not shared with other appliances).
5. When initially loading your new product, or whenever large quantities of warm contents are placed within the refrigerated storage compartment, minimize door openings for the next 12 hours to allow contents to pull down to compartment set temperature.
6. Maintaining a relatively full storage compartment will require less appliance run time than an empty compartment.
7. Ensure door closing is not obstructed by contents stored in your appliance.
8. Allow hot items to reach room temperature before placing in product.
9. Minimize door openings and duration of door openings.
10. Use the warmest temperature control set temperature that meets your personal preference and provides the proper storage for your stored contents.
11. When on vacation or away from home for extended periods, set the appliance to the warmest acceptable temperature for the stored contents.
12. Set the control to the "off" position if cleaning the appliance requires the door to be open for an extended period of time.
13. For wine storage products: When serving temperatures are not required, return the compartment(s) set temperature to the ideal red and white wine long-term storage temperature of 13°C / 55°F.

Long-Term Storage / Winterization

Outdoor Product Long-Term Storage / Winterization:

⚠️ WARNING: Operation of the unit at ambient temperatures below the recommended Winterization temperature will void your warranty.

1. Time to Winterize: when the daily low ambient temperature is expected to be below 55°F (13°C).
2. Remove all contents.
3. If necessary, move the unit so you can gain access to the rear of the product.
4. Unplug the unit from the power outlet.
5. It is also recommended that the power to the outlet be turned off at the circuit breaker.
6. Clean out behind grille: Remove the front grille by removing the screws from each end. Use a brush and vacuum to clean dirt and debris from the grille area.
7. Clean out the machine compartment: Remove the rear access cover by unscrewing the perimeter screws. Use a brush and vacuum to clean dirt and debris from the machine compartment. If the plastic defrost drain pan located under the compressor contains water, use a sponge to remove as much water as possible.
8. Thoroughly clean the toe-grille and re-install on the unit.
9. Thoroughly clean the rear access cover and re-install on the unit.
10. Wipe down all interior surfaces with an anti-bacterial cleaner, followed by a clean rinse with water to remove any residual chemicals which could cause staining. Do not use any abrasive cleaners or scouring pads.
11. Leave the door open and allow to completely dry out before closing the door.
12. Thoroughly clean the door gasket with an anti-bacterial cleaner, followed by a clean rinse with water.
13. Thoroughly clean the exterior with a cleaner approved for stainless steel. Do not use any abrasive cleaners or scouring pads. See "Stainless Steel Maintenance".
14. Any mounting hardware / fasteners that are showing signs of corrosion should be replaced.
15. Once the exterior has been thoroughly cleaned, you may want to apply a coating of car wax to help protect against spotting from moisture, dirt, and debris that may accumulate on the surfaces during the Winterization period.
16. ⚠️ WARNING: Do not place a cover on the unit, as this can trap condensation.

After completion of the above, you may choose to store the unit indoors, although this is not required.

Start-Up After Long-Term Storage:

1. If stored outside, it is recommended that the unit again be thoroughly inspected per the storage instructions above to address any dirt or debris from the weather and/or animals/insects.
2. Connect the unit to electrical power.
3. Turn power to the outlet back on at the circuit breaker.
4. Allow 24-hrs for the unit to stabilize before loading contents.

Diagrams show how to remove the front grille, access cover, and drain pan for cleaning.

Care and Cleaning

Front Grille: Be sure that nothing obstructs the required air flow openings in front of the cabinet. At least once or twice a year, brush or vacuum lint and dirt from the front grille area.

⚠️ CAUTION: SHOCK HAZARD: Disconnect electrical power from the appliance before cleaning with soap and water.

Cabinet: The painted cabinet can be washed with either a mild soap and water and thoroughly rinsed with clear water. NEVER use abrasive scouring cleaners.

Interior: Wash interior compartment with mild soap and water. Do NOT use an abrasive cleaner, solvent, polish cleaner or undiluted detergent.

Care of Appliance:

• Avoid leaning on the door; you may bend the door hinges or tip the appliance.
• Exercise caution when sweeping, vacuuming or mopping near the front of the appliance. Damage to the grille can occur.
• Periodically clean the interior of the appliance as needed.
• Periodically check and/or clean the front grille as needed.

In the Event of a Power Failure: If a power failure occurs, try to correct it as soon as possible. Minimize the number of door openings while the power is off so as not to adversely affect the appliance's temperature.

Light assembly replacement: All models use an LED to illuminate the interior of the appliance. This component is very reliable, but should it fail, contact a qualified service technician for replacement of the LED.

Stainless Steel Maintenance

Background: Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain or corrosion proof. Stainless steels can discolor or corrode if not maintained properly. The chromium content in stainless steel forms a passive oxide layer that protects the surface. If this surface can be damaged or contaminated, it may result in discoloration, staining, or corrosion of the base metal.

ℹ️ NOTE: Stainless steel products should never be installed, or stored in close proximity to chlorine chemicals.

Care & Cleaning: Routine cleaning of the stainless steel surfaces will serve to greatly extend the life of your product by removing contaminants. This is especially important in coastal areas which can expose the stainless to severe contaminants such as salt air.

The frequency of cleaning will depend upon the installation location, environmental, and usage conditions. It is strongly recommended to periodically inspect and thoroughly clean crevices, weld points, under gaskets, rivets, bolt heads, and any locations where small amounts of liquid could collect, become stagnant, and concentrate contaminates. Additionally, any mounting hardware that is showing signs of corrosion should be replaced.

Choosing a Cleaning Product: The choice of a proper cleaning product is ultimately that of the consumer, and there are many products from which to choose. Depending upon the type of cleaning and the degree of contamination, some products are better than others.

The simplest and most effective method for cleaning of most stainless steel products is to give the surfaces a brisk rubbing with a soft cloth soaked in warm water and a gentle detergent, or mild mixture of ammonia. Rubbing should, to the extent possible, follow the polish lines of the steel, and always ensure thorough rinsing after cleaning.

Although some products are called "stainless steel cleaners," some may contain abrasives which could scratch the surface, and some may contain chlorine bleach which will dull, tarnish or discolor the surface if not completely removed. Whichever cleaning product you choose, it should be used in strict accordance with the instructions of the cleaner manufacturer.

After the stainless surfaces have been thoroughly cleaned, a good quality car wax may be applied to help maintain the finish and protect against future staining.

⚠️ RISK OF FIRE OR EXPLOSION. FLAMMABLE REFRIGERANT USED.

• To be repaired only by trained service personnel.
• Do not puncture refrigerant tubing.
• Consult the repair manual before attempting to service this product. All safety precautions must be followed.
• Dispose of properly in accordance with Federal or Local Regulations.

R-600a is heavier than air; do not allow any leakage/migration to low areas such as basements and stairs.

Never use a torch on a fully charged refrigeration system.

Never substitute Marvel OEM replacement parts or methods of construction.

R-600a must be stored and transported in approved containers.

Handling Precautions:

• Only skilled and well-trained service technicians are permitted to service R-600a equipped products.
• All tools and equipment must be approved for use with R-600a refrigerant.
• Local, state, and federal laws and standards must be observed along with proper certification and licensing.
• Ventilation is required during servicing.
• No conversions to R-600a from any other refrigerants. OEM R-600a equipped units only.
• Service area must be free of ignition sources. No smoking is allowed in the service area.
• All replacement electrical components must be OEM and installed properly (sealed and covered).
• If the evaporator is cold prior to service, it must be thawed prior to service.
• When using a vacuum pump, start the pump before opening the refrigeration system.
• Vacuum pump and recovery equipment should be at least 10 feet from the work area.
• It is recommended that a simple LPG gas detector is on site during service.
• Ensure that all R-600a is removed from the system prior to brazing any part of the sealed system.
• Only a clean, dry, leak-free system should be charged with R-600a.

R-600A Specifications/Labeling: R-600a equipped products are labeled (both the unit and the compressor). R-600a is colorless and odorless. It is considered non-toxic, but is flammable when mixed with air. Do not remove or alter any R-600a labeling on the product. Use only a refrigerant grade R-600a from a properly labeled container.

Recovering/Reclaiming R-600A: (R-600a has been exempted from recovery/reclaiming requirements by the US EPA)

• Recovery/Reclaiming equipment must be approved for use with R-600a.
• Ensure the evaporator is at room temperature prior to recovery/reclaiming R-600a.
• Use a common piercing pliers or piercing valve to remove R-600a from the compressor process tube. (Note: Piercing devices must not be left on the system and must be replaced with a Schrader type valve.)
• Evacuate/reclaim via the piercing pliers to ensure the system is empty of R-600a before any system work is performed.
• The recovery cylinder must be evacuated (no air inside) prior to accepting R-600a. The recovery cylinder must not be filled more than 45% safe fill level and refrigerants must not be mixed. The recovery cylinder must be clearly marked with R600a and Flammable Warning labels.
• Ensure proper ventilation during recovery/reclaiming of R600a. Start vacuum pump/recovery pump prior to piercing the compressor process tube.
• Follow recovery/reclaim OEM instructions for the specific equipment used.

System Repair: Ensure no residual R-600a refrigerant is left within the system prior to repair (simple venting is not sufficient). Evacuate and charge with dry nitrogen for leak checks. Repair leaks or replace system parts as required. When re-brazing, the system must be purged with dry nitrogen and at least one access point open to the atmosphere. When re-brazing, proper ventilation is required along with constant monitoring for the presence of R600a refrigerant. The filter dryer must be replaced any time the sealed system is serviced. No system should be open to the atmosphere for longer than 15 minutes to avoid moisture migration into the system components.

Leak Detection: After removal of the R-600a, the unit can be charged with dry nitrogen or helium. Electronic leak detection or soap solution can be used to check for nitrogen/helium leaks. Never use a halide torch or lighted match to check the system for leaks at any time. The high side of the refrigeration system (compressor discharge to outlet of drier) must be leak tested with the compressor running. The low side of the refrigeration system (evaporator, compressor, and suction line) must be leak tested with the compressor off (equalized pressure).

Recharging: No air is ever to be allowed inside the refrigeration system (R-600a refrigerant or dry nitrogen only). Never use a torch on a fully charged refrigeration system. Install a Schrader Type access port on the compressor process stub. Proper ventilation during service is required. Never apply a torch to a charged R-600a refrigeration system. Use OEM replacement service parts and do not alter the construction of the unit. Evacuate the system to 100 microns prior to charging. Weigh in the R-600a charge using a refrigerant scale (run compressor an extra two minutes to clear the charging hoses). Seal the Schrader Type access port; a proper cap and seal must be used to close the system.

Summary: Safely handling R-600a requires proper procedures and training. R-600a approved service tools must be used. R-600a labeling must not be removed or altered.

Troubleshooting Guide

A table lists common concerns, potential causes, and recommended actions:

Main Control

The main control board is robust and rarely the cause of system issues. It is important to fully diagnose the board for any suspected failures before attempting removal. Follow the guidelines below to test and diagnose the main control.

Power Fault: If the unit does not power on, follow the flowchart below. Before beginning, verify the unit is not simply set to Sabbath mode.

• Check Voltage At Wall Outlet: No Voltage -> Alert Customer Of Power Failure. Voltage -> Verify Voltage At Main Control Voltage Input.
• No Voltage (at control): Replace Power Cord.
• Voltage (at control): Check Fuse F1 For Continuity. No Continuity -> Replace Fuse. Continuity -> Connect Test Display, Cycle Power And Check For Operation.
• Operating (after test): Inspect Customer UI and Data Cable.
• Not Operating (after test): Is the Rocker Switch Operating Properly? No -> Replace Rocker Switch. Yes -> Replace Main Board.

⚠️ CAUTION: Precautions must be taken while working with live electrical equipment. Be sure to follow proper safety procedures while performing tests on live systems.

Rocker Switch

A rocker switch is used to monitor door state. When the door is closed, it comes into contact with the rocker, closing a circuit which turns the light and display off. When the door is open, the rocker moves outward and opens the circuit. If the door is left open for longer than 5 minutes, the switch will trigger an error code and set an audible warning.

Defrost

Outdoor units defrost every 3 hours of compressor runtime for 40 minutes. If you have verified that the unit does not have an ambient air leak, utilize the Control Operation - Service section and adjust the unit to defrost every 2 hours for 60 minutes.

Remove Fan and Cover

Convection Cooling: This unit is equipped with an advanced convection cooling system that stabilizes cabinet temperature, cools product faster, and increases energy efficiency. The evaporator fan circulates air from the refrigeration zone, past the evaporator, and back into the zone. The fan has a factory-set 1-minute delay at the beginning of a cooling cycle and runs for an additional 2 minutes at the end. Fan delay times can be modified through the service menu.

Evaporator fan operation is also determined by the door switch state. If the door switch circuit opens, the fan stops. When the door switch circuit is closed, the fan will either continue running with the cooling cycle, or if not currently cooling, it will run for 1 minute to circulate air and clear condensation.

Note: If the unit is set to Sabbath mode, the evaporator fan will no longer respond to the door switch state.

For efficient operation, the evaporator fan blade and vents should be unobstructed and free of dust buildup.

Evaporator Fan Replacement: Should the evaporator fan need to be replaced, follow these steps:

1. Remove any product from the unit.
2. Remove unit from cabinetry to access the rear.
3. Disconnect power to the unit.
4. Remove the back panel from the unit.
5. Disconnect the fan electrical connection at the rear of the unit.
6. Remove insulating foam from the refrigerant line passthrough hole as needed to gain clearance for the fan plug.
7. Remove internal shelving.
8. Remove evaporator cover screws.
