!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 out for "just a few hours".
If you are getting rid of your old refrigerator, please fol-
low 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.
!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 in-
ternal components in place. The owners manual 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 damage, the packaging will be needed as
proof of damage in transit. Afterwards please dispose of all
items responsibly.
Note to Customer
This merchandise was carefully packed and thoroughly
inspected before leaving our plant. 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.
If the appliance was shipped, handled, or stored in other
than an upright position for any period of time, allow the ap-
pliance 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.
UNPACKING YOUR APPLIANCE

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 accor-
dance with the National Electrical Code and applicable lo-
cal 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 cir-
cumstances, be cut or removed.
Figure 4
NOTE
Ground Fault Circuit Interrupters (GFCI) are prone to nui-
sance tripping which will cause the appliance to shut down.
GFCI’s are generally not used on circuits with power equip-
ment that must run unattended for long periods of time, un-
less required to meet local building codes and ordinances.

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 circumstanc-
es, 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.

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).

!CAUTION
Front grille
screws
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 ow may be restricted. (See
Figure 8).
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.
Figure 9
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. (See Figure 9).

SIDE-BY-SIDE AND STACKING INSTALLATIONS
Side-by-Side Installation
Other Site Requirements
Units must operate from separate, properly grounded elec-
trical receptacles placed according to each unit's electrical
specications requirements.
Cutout width for a side-by-side installation is the total of the
widths listed under Cutout Dimensions in each unit's Instal-
lation Guide. Each door can be opened individually (one at
a time) without interference.
Figure 10
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.

!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

INTEGRATED PANEL INSTALLATION
Full Integrated Panel Installation Instructions
Determine Wood Screw Requirements
1. A #10 pan head wood screw should be used to proper-
ly secure the integrated panel. A quantity of 16 screws
are supplied with the unit in the literature pack.
2. Use only pan head screws.
3. If your integrated panel is thinner than 5⁄8" (15.9 mm)
you will need to purchase shorter screws. The longer
screws will break through the front of the panel.
Figure 18
• Never attempt to repair or perform maintenance on
the appliance until the main electrical power has been
disconnected. Turning the appliance control "OFF"
does not remove electrical power from the units wiring.
• Replace all parts and panels before operating.
!WARNING
Electrocution Hazard
!CAUTION
It is important to use the factory provided grille that came
with the product to assure proper air ow is maintained
through the condenser. The use of a custom grille is not
recommended and will void the warranty.
15

Cut the integrated panel to the dimensions shown below in
Figure 21. On the top drawer only, drill the 2 counter-bored
holes which are clearance for screw heads on the face of
the top drawer and the lock hole at the bottom of the top
drawer only.
This is also a convenient time to locate and drill the holes
for your handle. Most often the handle is to match that of
the surrounding cabinetry. If your handle attaches from the
back-side of the custom panel, locate the mounting holes
while the panel is attached to the drawer and cabinet. After
the panel is removed from the drawer, drill the mounting
holes from the front, to the recommended diameter of the
handle manufacturer. Counter bore the back-side of the
panel so the screw heads do not interfere with the surface
of the drawer.
Step 2: Size the Integrated Panel

Step 1: Remove Drawers from unit.
1. Begin by pulling out the top drawer. (See Figure 14).
Remove screws securing drawer to slides (See Figure
15). Pull drawer forward, lift up and out to clear clips in
rear of drawer. Move drawer forward about 1" (2.5 cm)
and set down on slides. At the right rear corner of the
drawer disconnect the display wire harness (See Figure
14a). Remove the drawer from the unit by lifting up o󰀨
of the slides. Repeat for bottom drawer but disregard
the harness instructions as there is no wiring to the bot-
tom drawer.
2. Remove the drawer divider from the drawer and
remove the gasket from the drawer front. (See Figure
13). Do this by pulling the gasket out of the channel
that holds it to the drawer front. This will expose the
clearance holes for mounting the integrated panel.
(See Figure 17).

Step 3: Attach the Integrated Panel to the
Drawer
1. Set the integrated panel on drawer front face and align
edges. (See Figure 17). The custom integrated panel
should be ush with the top of the drawer and centered
on the width of the drawer. Clamp panel in position and
mark pilot hole locations. Pick the required pilot hole
size from "Table A" below and drill the pilot holes ensur-
ing not to drill all the way through the integrated panel.

Material Type #8 Wood Screw
Hardwood 1⁄8Diameter Pilot Hole
Softwood 7⁄64 Diameter Pilot Hole
2. Insert wood screws through clearance holes and
tighten to secure integrated panel.
3. Reinstall gasket into channel. Make sure the corners
are fully inserted.
4. Place the drawer divider back into the drawer.

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 pos-
sible. Minimize the number of door openings while the
power is o󰀨 so as not to adversely a󰀨ect the appliance's
temperature.
Light assembly replacement
All models use an LED to illuminate the interior of the ap-
pliance. This component is very reliable, but should it fail,
contact a qualied service technician for replacement of the
LED.
CARE AND CLEANING
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 compart-
ment.
7. Ensure door closing is not obstructed by contents
stored in your appliance.
8. Allow hot items to reach room temperature before plac-
ing 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 “o󰀨” 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.
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.
