** 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.

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.

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.

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

DRAWER DIVIDER

Drawer Divider
The top and bottom drawer have an adjustable drawer divider. To adjust the divider, making the 4 areas larger or smaller, move the center post along the length of the rods in either direction. See Figure 16 and 16a. The divider can also be removed from the  drawer.

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 (see page 8).

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

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.

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.
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 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.
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. 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 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.

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 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.

EXTENDED NON-USE

Vacation/Holiday, Prolonged Shutdown
The following steps are recommended for periods of extended non-use:

1. Remove all consumable content from the unit.
2. Disconnect the power cord from its outlet/socket and leave it disconnected until the unit is returned to service.
3. If ice is on the evaporator, allow ice to thaw naturally.
4. Clean and dry the interior of the unit. Ensure all water has been removed from the unit.
5. The door must remain open to prevent formation of mold and mildew. Open door a minimum of 2″ (50 mm) to provide the necessary ventilation.

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 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. 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.

1. Remove any product from the unit.
