UNPACKING YOUR APPLIANCE
!WARNING
EXCESSIVE WEIGHT HAZARD
Use two or more people to move product.
Failure to do so can result in personal injury.
Remove Interior Packaging
Your appliance has been packed for shipment with all parts
that could be damaged by movement securely fastened.
Remove internal packing materials and any tape holding
internal components in place. The getting started guide is
shipped inside the product in a plastic bag along with the
warranty registration card and other accessory items.
Important
Keep your carton and packaging until your appliance has
been thoroughly inspected and found to be in good condi-
tion. If there is any damage, the packaging will be needed
as proof of damage in transit. Afterwards, please dispose of
all items responsibly.
!WARNING
WARNING - Dispose of the plastic bags which can
be a su󰀨ocation hazard.
Note to Customer
This merchandise was carefully packed and thoroughly
inspected before leaving out facility. Responsibility for its
safe delivery was assumed by the retailer upon acceptance
of the shipment. Claims for loss or damage sustained in
transit must be made to the retailer.
DO NOT RETURN DAMAGED MERCHANDISE TO THE
MANUFACTURER - FILE THE CLAIM WITH THE
RETAILER.
NOTE
!CAUTION
If the appliance was shipped, handled or stored in other
than an upright position for any period of time, allow the
appliance to sit upright for a period of at least 24 hours
before plugging in. This will assure oil returns to the
compressor. Plugging the appliance in immediately may
cause damage to internal parts.
!WARNING
WARNING - Help Prevent Tragedies
Child entrapment and su󰀨ocation are not problems of
the past. Junked or abandoned refrigerators are still
dangerous, even if they sit outside 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 o󰀨 the doors or remove the drawers.
• Leave the shelves in place so children may not
easily climb inside.

ELECTRICAL
Do not remove
ground prong
!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.
• Do not use an adapter.
• 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. 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, unles required to meet local building codes and
ordinances.

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 applica-
tion as they are too narrow, but a recessed outlet box
equivalent to Arlington #DVFR1W is recommended for
this application.

Front grille

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 specications, the recom-
mended 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 appli-
ance. 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 unobstruct-
ed. All Marvel Professional models with articulated hinges
are intended for built-in applications only.
Front Grille
Do not obstruct the front grille. The openings within the
front grille allow air to ow through the condenser heat ex-
changer. Restrictions to this air ow 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.
INSTALLING YOUR APPLIANCE
!WARNING
An optional stacking kit, for 24" wide models, is re-
quired 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
Leveling Legs
Adjustable legs at the front and rear corners of the appli-
ance should be set so the unit is rmly positioned on the
oor and level from side to side and front to back. The over-
all 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 oor beneath the legs to avoid
scratching the oor. 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 appli-
ance 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 ad-
justed to the desired height. When adjustment is complete
tighten the two front grille screws.

Other Site Requirements
Units must operate from separate, properly grounded elec-

To ensure unobstructed door swing (opening both doors at
the same time), 1/4" (6.4 mm) of space needs to be maint-
ained 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.

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 dam-
age or personal injury.

Step 3: Assemble the Panel to the Door

screws provided in the literature pack. Remove the clamps
and replace the gasket in the gasket extrusion channels of
the door. Some force may be required to seat the gasket
into the channels. Be sure the gasket corners are seated
properly.
