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 out for “just a few hours”.
If you are getting rid of your old refrigerator, please follow the instructions below to help prevent accidents.
Before you throw away your old refrigerator or freezer:

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

ELECTRICAL

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. (See Figure 2).

• Do not use an adapter. (See Figure 3).

• 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 accordance with the National Electrical Code and applicable local 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 circumstances, be cut or removed.

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.

PRODUCT DIMENSIONS

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, (see Figure 12).

PRODUCT DATA

ELECTRICAL REQUIREMENTS #| PRODUCT WEIGHT
115V/60Hz/15A| 140 lbs (63.6 kg)

• To install (F) models with the door face flush with adjacent cabinetry doors, custom decorative panel thickness cannot exceed 3⁄4″ (19 mm).
  ** Minimum rough-in opening required is 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 of your appliance. We recommend a location where the unit will be out of direct sunlight and away from heat sources. To ensure your product performs to specifications, 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 counter top can be installed around the appliance as long as the front grille remains unobstructed.
All Marvel Professional 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
Front Grille
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 to not be obstructed and the grille openings kept clean. Marvel does not  ecommend the use of a custom made grille as air flow may be restricted. (See Figure 8).

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 of your Marvel appliance may be adjusted higher (by turning the leveling leg out, CCW) and lower (by turning the leveling leg in, CW).
To adjust the leveling legs, place the appliance on a solid surface and protect the floor beneath the legs to avoid scratching the floor. With the assistance of another person, lean the appliance back to access the front leveling legs.
Raise or lower the legs to the required dimension by turning the legs. Repeat this process for the rear by tilting the appliance forward using caution. On a level surface check the appliance for levelness and adjust accordingly.
The front grille screws may be loosened and the grille adjusted to the desired height. When adjustment is complete tighten the two front grille screws. (See Figure 9).

SIDE-BY-SIDE AND STACKING INSTALLATIONS

Side-by-Side Installation
Other Site Requirements
Units must operate from separate, properly grounded electrical receptacles placed according to each unit’s electrical specifications requirements. Cutout width for a side-by-side installation is the total of the widths listed under Cutout Dimensions in each unit’s Installation Guide. Each door can be opened individually (one at a time) without interference.

However, 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.

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.

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.

INSTALLING THE ANTI TIP DEVICE

WARNING

| • ALL APPLIANCES CAN TIP RESULTING IN INJURY.
• INSTALL THE ANTI-TIP BRACKET PACKED WITH THE APPLIANCE.
• FOLLOW THE INSTRUCTIONS BELOW
---|---

Anti-Tip Device

WARNING
If your beverage center is not located under a counter top (free standing), you must use an anti-tip device installed as per these instructions. If the beverage center is removed from its location for any reason, make sure that the device is properly engaged with the anti-tip bracket when you push the beverage center back into the original location. If the device is not properly engaged, there is a risk of the beverage center tipping over, with the potential for property damage or personal injury.

NOTE
If installing on a concrete floor, concrete fasteners are required, (not included with the anti-tip kit).
CAUTION
Any finished flooring should be protected with appropriate material to avoid damage when moving the unit.

Floor Mount Installation
The anti-tip bracket is to be located on the floor in the left or right rear corner of the wine cellar as shown in Figure 14.

Step by step instructions for locating the position of the bracket:

1. Decide where you want to place the beverage center.
   Slide it into place, being careful not to damage the floor, leaving 1″ (2.5 cm) of clearance from the rear wall to allow room for the anti-tip bracket.

2. Raise the rear leveling legs approximately 1⁄4″ (6 mm) to allow engagement with the anti-tip bracket. Level the unit by adjusting all the leveling legs as required. Turning the leveling leg counterclockwise will raise the unit and clockwise will lower the unit.

3. Make sure the beverage center is in the desired location, then mark on the floor the rear and side corner of the cabinet where the anti-tip bracket will be installed. If the installation does not allow marking the rear corner of the cabinet, then make temporary lines on the floor marking the front corner of the cabinet, excluding the door. Slide the beverage center out of the way. From the temporary line extend the sidewall line back 21 1⁄2″ (54.6 cm) as shown in Figure 15.

4. Align the anti-tip bracket to the marks on the floor so the side of the bracket lines up with the side of the cabinet mark, and the “V” notches on the anti-tip bracket line up with the end of the 21 1⁄2″ (54.6 cm) line (Rear of cabinet line).

5. Fasten the anti-tip bracket to the floor using the supplied screw. (See Figure 15).

6. Slide the cabinet back into position, making sure the rear cabinet leveling leg slides under the anti-tip bracket engaging the slot.

NOTE
When the floor mounted anti-tip bracket is used the minimum adjusted height of the cabinet is increased by 3⁄8″ (9 mm).

INSTALLING THE WATER SUPPLY

Water Supply

CAUTION
Observe and follow all local building codes when installing this appliance.
Use 1/4″ 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 kinkthe 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.

Connect the copper tubing water supply to the water valve inlet with the compression nut fitting provided. Secure the water supply line to the back of the cabinet with the screw and clamp provided in the corner of the back panel. (See Figure 7).
Water pressure must be at a minimum of 20 psi for proper operation and a maximum of 120 psi.
Make certain all water connections are watertight after installation. Form the tubing so that it will not vibrate against the cabinet body or kink when your appliance is set in position.

NOTE

• Do not use any thread sealers on these water line fittings.
• 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.![Marvel MPRF424 24 in Professional Built in Refrigerator Freezer

• OPERATION](https://manuals.plus/wp-content/uploads/2022/11/Marvel-MPRF424-24 -in-Professional-Built-in-Refrigerator-Freezer-OPERATION.jpg) 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. (See Figure 8).
  • When the freezer section and ice-maker unit has sufficiently cooled, the ice-maker will 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 at the up most position. (See Figure 8).

NOTE
It is recommended the ice-maker is shut off when removing the bucket, or ice may be dispensed onto the freezer compartment floor.
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 front upward and lift out. (See Figure 28). To 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

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  ppliance’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 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.

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 contami-nants. 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 thor-oughly 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.
Frequency of cleaning will depend upon the installation location, environmental, 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 sur-faces 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 clean-ers,” 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.

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 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.

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.

Troubleshooting – Extended
CAUTION
Never attempt to repair or perform maintenance on the unit until the main electrical power has been disconnected from the unit.
SPECIFIC ERRORS AND ISSUES
The advanced diagnostic capabilities of the electronic controls allows for easy and thorough troubleshooting.
Navigation of the control is the key and is explained in the CONTROL OPERATION section of the manual, along with control button layout, control function descriptions,
a service mode menu and service menu selection explanations.
Verification of temperature and thermistor performance can be identified by directly viewing thermistor readings in the service mode.
Included in this section are some diagnostic tips and of course, if additional help is required, please contact the Marvel, “Customer Care Facility” at +1.616.754.5601 for assistance.

NORMAL OPERATING SOUNDS
All models incorporate rigid foam insulated cabinets to provide high thermal efficiency and maximum sound reduction for its internal working components. Despite this technology, your model may make sounds that are unfamiliar.
Normal operating sounds may be more noticeable because of the unit’s environment. Hard surfaces such as cabinets, wood, vinyl or tiled floors and paneled walls have a tendency to reflect normal appliance operating noises.
Listed below are common refrigeration components with a brief description of the normal sounds they make.

NOTE:
Your product may not contain all the components listed.

• Compressor: The compressor makes a hum or pulsing sound that may be heard when it operates.
• Evaporator: Refrigerant flowing through an evaporator may sound like boiling liquid.
• Condenser Fan: Air moving through a condenser may be heard.
• Automatic Defrost Drain Pan: Water may be heard dripping or running into the drain pan when the unit is in the defrost cycle.

Solenoid Valves: An occasional clicking sound may be heard as solenoid valves are operated.

TROUBLESHOOTING GUIDE

Is condenser clean?
Confirm condenser fan operation.
Compressor not operating| Test overload and relay, replace as needed.
Compressor operating – no cooling| Refer to System Diagnosis Guide.
Frozen Product| Control set too cold| Adjust Set Point Temp accordingly.
Thermistor failure| Check Error Log in Service Mode, OHM thermistor.
Frost Buildup Inside Unit| Door Ajar or Restricted from Closing| Check door clearance to adjoining cabinetry. Check distribution of product in unit.
Thermistor failure| OHM thermistor
Display Not Working| Display unplugged| Verify that both ends of the display wiring are firmly connected.
Display wiring broken or damaged| Perform continuity test of wiring and replace as needed.
Interior Lights Not Working| Door switch misaligned or defective| Check the function of reed switch and door magnet adjustment.
Noisy| Refrigeration tubing touching cabinet| Carefully reposition tubing.
Fan blade obstruction (wiring, foam insulation, packaging material)| Remove obstruction.

MAIN CONTROL
The main control board is very robust and is rarely the cause of system issues. It is important to fully diagnose the board for any suspected failures before attempting to remove the board for replacement or service. Follow the guidelines below to fully test and diagnose the main control.
Power Fault
If the unit does not (or seems to not) power on, follow the flow chart below to help diagnose the issue. Before begin­ ning it is important to first verify the unit is not simply set to sabbath mode.

CAUTION
Precautions must be taken while working with live electrical equipment. Be sure to follow proper safety procedures while performing tests on live systems.
REED SWITCH
A reed switch is used to monitor door state. When the door is closed it comes into contact with the reed which closes a circuit which turns the light and display off. When the door is open the reed 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.

CONTROL FUNCTION GUIDE

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 left 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  hrough 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. Thermistor Resistance Data
