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.

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 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
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 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 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.

Front grille, keep this area open.

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.

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

amount of chromium present. It is this chromium that
surface can be damaged or contaminated, which may result in discoloration, staining, or corrosion of the base metal.

Whichever cleaning product you chose, it should be used in strict accordance with the instructions of the cleaner manufacturer.

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

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.
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.

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 insure thorough rinsing after cleaning.
Although some products are called “stainless steel cleaners,” some may contain abrasives which could scratch the
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

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 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 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.

Thermistors
Thermistors are used for various temperature readings. Thermistors provid e 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.
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 corrod ed 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 d ielectric 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 one thermistor.
Thermistor (Zone): Located along the right hand sid e wall. It is used to maintain the operating temperature within that zone.
THERMISTOR FAILURE

Remove Fan and Cover
CONVECTION COOLING This unit is equipped with an advanced convection cooling system. Convection cooling stabilizes cabinet temperature, cools product faster and increases energy efficiency.
Evaporator Fan The evaporator fan is responsible for circulating warm air from the refrigeration zone, past the evaporator and back into the refrigerated zone.
The evaporator fan is factory set to have a 1 minute delay at the beginning of a cooling cycle. This delay gives the evaporator time to cool properly before warm air is passed over it. The fan will continue to run for an additional 2 minutes at the end of a cooling cycle. Fan delay times can be modified through the service menu.
Evaporator fan operation is also determined by door switch state. If the door switch circuit opens, the fan will stop. When the door switch circuit is closed the fan will either continue running with the cooling cycle, or if not currently cooling, the fan will run for 1 minute to circulate air and clear any condensation that may have appeared on glass doors and shelves.
Note: If the unit is set to sabbath mode, the evaporator fan will no longer respond to the state of the door switch.
In order to operate efficiently, the evaporator fan blade and vents should be unobstructed and free of any dust buildup.
Evaporator Fan Replacement Should the evaporator fan need to be replaced follow the steps below.
1. Remove any product from the unit.
2. Remove unit from cabinetry to access rear.
3. Disconnect power to the unit.
4. Remove back panel from unit.

ranty fit for a particular purpose is limited to the duration of these warranties, and only extends to five years in duration for the parts described
