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 6).

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).
Front grille
screws
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.

Leveling
Legs
Figure 9
WARNING
Leveling Legs
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 Leveling
Legs
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. (See
Figure 8).
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).
Figure 8
Front grille, keep
this area open.

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.
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.
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.
Figure 12
Figure 10
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.
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.

!
Figure 14
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 211⁄2" (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 211⁄2" (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).

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.
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
