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.

!CAUTION
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 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.

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).

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.
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.
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 thor-
oughly clean crevices, weld points, under gaskets, rivets,
bolt heads, and any locations where small amounts of liquid
could collect, become stagnant, and concentrate contami-
nates. 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 sur-
faces a brisk rubbing with a soft cloth soaked in warm water
and a gentle detergent, or mild mixture of ammonia. Rub-
bing 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 clean-
ers," 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
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
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.
