  • 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.

Electrical Connection
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 accor-dance with the National Electrical Code and applicable lo- cal codes and ordinances (see Figure 4). 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 cir-cumstances, be cut or removed.

NOTE
Ground Fault Circuit Interrupters (GFCI) are prone to nui-sance tripping which will cause the appliance to shut down. GFCI’s are generally not used on circuits with power equip-ment that must run unattended for long periods of time, un-less required to meet local building codes and ordinances.

INSTALLING THE WATER SUPPLY

Water SupplyMarvel MORF224SS31A Stainless Steel Outdoor-Built-In-
Refrigerator-and-Freezer-with-Lock,-24-Inch-FIG- \(1\)

  • Observe and follow all local building codes when installing this appliance.
  • Use 14″ outside diameter copper tubing for your water supply which is available at any local hardware or plumbing supply store. Bend the 1 4″ copper tubing to suit your installation being sure not to kink the tubing. Purchase enough copper tubing length and coil it behind the unit to form a “service loop” which will allow the appliance to be pulled out from the installation for servicing or cleaning. Connect the copper tubing to the “top side” of a cold water pipe to prevent the ice-maker from plugging with sediment.
  • A shutoff valve is recommended on the water supply line to ease servicing the appliance. NOTE:
  • A SELF-PIERCING TYPE VALVE IS NOT RECOMMENDED as they are prone to clogging with sediment which will create pressure drop reducing the water supply to the unit.

NOTE

  • Do not use any thread sealers on these water
  • Reverse osmosis, softened water, and deionized water are not recommended as they will adversely affect the quality of the ice.

ICE-MAKER OPERATION

CAUTION

The water supply to the ice-maker must be turned on prior to turning the ice- maker on. Failure to do so will cause rapid dry cycling of the ice-maker mold heater resulting in temperature control issues in the freezer compartment

Ice-maker operation

  • The unit must be installed level for proper ice-maker operation.
  • The shutoff arm wire must be down in its lowest position for the ice-maker to operate.
  • When the freezer section and ice-maker unit harvest ice cubes automatically.
  • When the ice bucket is full, the ice-maker will automatically shut off.
  • You may manually stop the ice-maker by raising the shut off arm to the locking position

NOTE

It is recommended the ice-maker is shut off when removing the bucket, or ice may be dispensed onto If the ice is not used regularly, it will clump together with time. For best ice results, discard ice in the bin as required and allow the ice-maker to make a new fresh batch of ice. Shut-off the ice-maker by raising the shut-off arm before removing the bucket.

Long and short term storage of ice-maker

When operation of the appliance is to be discontinued for any length of time, the ice cube mold in the ice-maker should be emptied by allowing the ice-maker to dispense cubes with the water supply turned off.

  1. Turn the water supply off.
  2. Raise the ice-maker bail arm.
  3. Empty the ice bucket.
  4. Replace the ice bucket in the unit and lower the bail arm.

Dispensing of the cubes should occur within 2 hours. After the ice-cubes dispense – empty, clean, and replace the ice cube bucket, and raise the bail arm.

INTERIOR ADJUSTMENTS

CAUTION

Make sure your cantilever shelf is secure on the shelf supports by pressing down on the shelf before loading

CAUTION

Never try to move a loaded shelf, remove everything from the shelf before moving. Use both hands when moving the shelf.

To Add or Remove a Shelf

Remove stored product from the shelf. Do not try to remove a loaded shelf from the appliance. Grasp the shelf front with both hands, rotate the install a shelf insert the shelf in the appliance and insert the top hooks into the shelf support slots and drop the shelf down so the hooks drop over the bottom of the slots.

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
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

  1. Avoid leaning on the door, you may bend the door hinges or tip the appliance.
  2. Exercise caution when sweeping, vacuuming or mopping near the front of the appliance. Damage to the grille can occur.
  3. Periodically clean the interior of the appliance as needed.
  4. 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.

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 front of appliance beneath 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 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 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.

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. Stain-less steels can discolor or corrode if not maintained prop-erly.Stainless steels differ from ordinary carbon steels by the amount of chromium present. It is this chromium that provides an invisible protective film on the surface called chrome-oxide. This protective chrome-oxide film on the surface can be damaged or contaminated, which may result in discoloration, staining, or corrosion of the base metal.

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 halide salts, (sodium chloride).
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 contami- nates. Additionally, any mounting hardware that is showing signs of corrosion should be replaced.
The frequency of cleaning will depend upon the installation location, environment, and usage conditions

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.
  • Typically the most effective and efficient means for routine 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. Rub- bing should, to the extent possible, follow the polish lines of the steel, and always insure thorough rinsing after cleaning.
  • Although some products are called “stainless steel cleaners,” some may contain abrasives which could scratch the surface, (compromising the protective chrome-oxide film), and some many contain chlorine bleach which will dull, tarnish or discolor the surface if not completely removed.
  • After the stainless surfaces have been thoroughly cleaned, a good quality car wax may be applied to help maintain the finish.

NOTE

  • Stainless steel products should never be installed, or stored in close proximity to chlorine chemicals.
  • Whichever cleaning product you chose, it should be used in strict accordance with the instructions of the cleaner manufacturer.

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 front of appliance be- neath 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 arge quantities of warm contents are placed within 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 pe- riods, set the appliance to warmest acceptable tem- perature 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 tem- perature of 13°C/ 55°F

  • No conversions to R-600a from any other refrigerants. OEM R-600a equipped unit 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 pump before opening 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.
  • R-600a 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 lelt on the system and must be replaced with a Schrader type valve.) Evacuate/reclaim via the piecing 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 R- 600a and Flammable Warning labels. Ensure proper ventilation during recovery/reclaiming of R- 600a. 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.

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. 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.

SHOWROOM MODE
This mode is designed to show units in a display environment. When in this mode the only functions will be the control and cabinet lights. The compressor, fans, etc. will not operate. To enter/exit this mode hold the light key and the power key for 5 seconds. The display will f1ash once and beep and the degree symbol will begin to f1ash. When the degree symbol is f1ashing the unit will allow the use of the control for demonstrations. The unit can be le in this mode indefinitely.

SERVICE MODE
This mode has options available for service diagnostics. To enter the mode hold the hidden key for 10 seconds. The display will show “O.” When in this mode use the up and down arrows to select the desired option. The LIGHT key is the ENTER key and will initiate the function. If changing a setting, you must press the LIGHT key again to retain the changed setting. To exit the service mode scroll to option “O” and press the LIGHT key. After Ave minutes of not touching any keys the mode will also exit automatically.

Thermistors

Thermistors are used for various temperature readings. Thermistors provide reliable temperature readings using a resistance which varies based on surrounding temperatures. If a faulty thermistor is suspected it may be tested using an accurate ohmmeter. Both thermistors in the unit are identical. If a thermistor is suspected of being defective, the resistance can be verified. Place the thermistor in an ice water bath, the resistance should read 16.lk Ohms +/-5% on your meter. Thermistor connections must be kept clean. A thermistor connection that has become corroded can cause resistance values from the thermistor to change as they pass through a dirty connection to the board. It is for that reason that we apply dielectric grease to all of our thermistor connections. Dielectric grease will help to keep thermistor connections clean and dry. If you change a thermistor in the unit please re- apply dielectric grease to the connection. If you encounter a dirty thermistor connection, you should replace the thermistor and the thermistor harness. Thermistor error information can be found in the Control Operations – Service section. This unit has two thermistors.

Thermistor one (Zone):
Located along the right hand side wall. It is used to maintain the operating temperature within that zone. Thermistor two (Evaporator): Located on the evaporator. It is used for defrost.

THERMISTOR FAILURE

Zone Thermistor
If the zone thermistor in the unit fails, the unit will continue to cool in a backup mode (Self Preservation Mode) to preserve the integrity of the contents. The unit will otherwise operate normally.

Evaporator Thermistor
If the evaporator thermistor fails, the unit will rely on a preset defrost timer during defrost cycles. The unit will otherwise operate normally. Refer to defrost section.
