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.

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 specications, 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).
T
o 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.

Step 1: Removing the Door and Hinges
Hold the door secure in the closed position and remove
Hinge Pin from the Upper Hinge using a 1/8” Hex Key tool.
Slowly remove the door by sliding outward away from the
cabinet and lift to remove o the Lower Hinge. If reversing
the door, remove hinges from cabinet per Door Reversal
Instructions.
Remove the hinge bushing from the adaptor plate. A new
bushing is included in the literature pack with your unit.
Cut and prepare panels according to the information
provided in the Integrated Panel Dimensions section.
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.
INTEGRATED DOOR PANEL INSTALLATION
Step 2: Remove the Door Gasket
With the door laying on a at surface and starting at a
corner of the door, remove the magnetic door gasket from
the interior side of the door. Set the gasket aside on a at
surface.
There are 10 holes in the gasket retainer extrusions (3 on
each side and 2 at the top and bottom) which are used to
fasten the panel to the front of the door. The screws are
provided in the literature pack.
Step 3: Assemble the Panel to the Door
The preferred method of attaching the panel to the door
is to clamp the panel to the door so it cannot move while
drilling the screw pilot holes. Use bar clamps or "C" clamps
with pads on the clamping surfaces that will not mar the
panel or the door. The custom panel should be ush with
the top of the door and centered along the width of the
door. Drill holes through the gasket extrusion using the 10
holes as pilot holes. Use the drill size from the chart in the
table below being careful not to drill through the front sur-
face of the panel. Fasten the panel to the door with the 10
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.

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.
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.
27
Vacation/Holiday, Prolonged Shutdown
The following steps are recommended for periods of ex-
tended non-use:
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.
Winterization
If the unit will be exposed to temperatures of 40° F (5° C) or
less, the steps above must be followed.
For questions regarding winterization, please call Marvel at
(616) 754-5601.

MAIN CONTROL
The main control board is very robust and is rarely the
cause of system issues. It is important to fully diagnose
the board for any suspected failures before attempting
to remove the board for replacement or service. Follow
the guidelines below to fully test and diagnose the main
control.
Power Fault
If the unit does not (or seems to not) power on, follow the
ow chart below to help diagnose the issue. Before begin-
ning it is important to rst verify the unit is not simply set
to sabbath mode.

CAUTION
!
Precautions must be taken while working with
live electrical equipment. Be sure to follow
proper safety procedures while performing tests
on live systems.
ROCKER SWITCH
A rocker switch is used to monitor door state. When the
door is closed it comes into contact with the rocker which
closes a circuit which turns the light and display off. When
the door is open the rocker moves outward and opens the
circuit. If the door is left open for longer than 5 minutes
the switch will trigger an error code and set an audible
warning.
44
Thermistors
Thermistors are used for various temperature readings.
Thermistors provide reliable temperature readings
using a resistance which varies based on surrounding
temperatures. If a faulty thermistor is suspected it may be
tested using an accurate ohmmeter.
If a thermistor is suspected of being defective, the
resistance can be veried. Place the thermistor in an ice
water bath, the resistance should read 16.lk Ohms +/-5%
on your meter.
Thermistor connections must be kept clean. A thermistor
connection that has become corroded can cause resistance
values from the thermistor to change as they pass through
a dirty connection to the board.
It is for that reason that we apply dielectric grease to all of
our thermistor connections. Dielectric grease will help to
keep thermistor connections clean and dry.
If you change a thermistor in the unit please re-apply
dielectric grease to the connection. If you encounter
a dirty thermistor connection, you should replace the
thermistor and the thermistor harness.
Thermistor error information can be found in the Control
Operations - Service section.
This unit has one thermistor.
Thermistor (Zone):
Located along the right hand side wall. It is used to
maintain the operating temperature within that zone.
THERMISTOR FAILURE
Zone Thermistor
If the zone thermistor in the unit fails, the unit will
continue to cool in a backup mode
(
Self Preservation Mode)
to preserve the integrity of the contents. The unit will
otherwise operate normally.

CONVECTION COOLING
This unit is equipped with an advanced convection cooling
system. Convection cooling stabilizes cabinet temperature,
cools product faster and increases energy eciency.
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 modied 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 eciently, the evaporator fan blade
and vents should be unobstructed and free of any dust
buildup.
Evaporator Fan Replacement
Should the evaporator fan need to be replaced follow the
steps below.
1. Remove any product from the unit.
2. Remove unit from cabinetry to access rear.
3. Disconnect power to the unit.
4. Remove back panel from unit.
5. Disconnect fan electrical connection at rear of unit.
6. Remove insulating foam from refrigerant line pass-
through hole as needed to gain clearance for fan plug.
