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
recommended installation location temperature range is
from 55°F to 100°F (13°C to 38°C).
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 Outdoor models with
articulated hinges are intended for built-in applications only.

CARE & CLEANING
Defrosting
Under normal conditions this unit does not require manual
defrosting. Minor frost on the rear wall or visible through the
evaporator plate vents is normal and will melt during each
o cycle.
If there is excessive build-up of 1/4” (6 mm) or more,
manually defrost the unit.
Ensure the door is closing and sealing properly.
High ambient temperature and excessive humidity can also
produce frost.
DO NOT use an ice pick or other sharp instrument to help
speed up defrosting. These instruments can puncture the
inner lining or damage the cooling unit. DO NOT use any
type of heater to defrost. Using a heater to speed up
defrosting can cause personal injury and damage to the
inner
lining.
The drain pan was not designed to capture the water
created when manually defrosting. To prevent water from
overowing the drain pan and possibly damaging water
sensitive ooring, the unit must be removed from cabinetry.
To defrost:
1. Disconnect power to the unit.
2. Remove all products from the interior.
3. Prop the door in an open position (2 in. [50 mm]
minimum).
4. Allow the frost to melt naturally.
5. After the frost melts completely clean the interior and
all removed components (see Interior Cleaning).
6. When the interior is dry, reconnect power and turn unit
on.
Stainless Models
Stainless door panels and handles can discolor when ex-
posed to chlorine gas, pool chemicals, saltwater or
cleaners with bleach.
Keep your stainless unit looking new by cleaning with a
good quality all-in-one stainless steel cleaner and polish
monthly. For best results use Claire® Stainless Steel
Polish and Cleaner. Comparable products are acceptable.
Frequent cleaning will remove surface contamination that
could lead to rust. Some installations may require cleaning
weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on any
glass surfaces.
Clean any glass surfaces with a non-chlorine glass cleaner.
Do not use cleaners not speci cally intended for stainless
steel on stainless steel surfaces {this includes glass, tile
and counter cleaners).
If any surface discoloring or rusting appears, clean it
quickly with Bon-Ami® or Barkeepers Friend Cleanser®
and a nonabrasive cloth. Always clean with the grain. Al-
ways nish with Claire® Stainless Steel Polish and Cleaner
or comparable product to prevent further problems.
Using abrasive pads such as Scotchbrite™ will cause the
graining in the stainless steel to become blurred.
Rust not cleaned up promptly can penetrate the surface of
the stainless steel and complete removal of the rust may
not be possible.
Integrated Models
To clean integrated panels, use household cleaner per the
cabinet manufacturer’s recommendation.
Interior Cleaning
Disconnect power to the unit.
Clean the interior and all removed components using a mild
nonabrasive detergent and warm water solution applied

26
STAINLESS STEEL MAINTENANCE
NOTE
Background
Stainless steel does not stain, corrode, or rust as easily as
ordinary steel, but it is not stain or corrosion proof.
Stainless steels can discolor or corrode if not maintained
properly.
Stainless steels dier from ordinary carbon steels by the
amount of chromium present. It is this chromium that
provides an invisible protective lm on the surface called
chrome-oxide. This protective chrome-oxide lm on the
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
contaminants. This is especially important in coastal areas
which can expose the stainless to severe contaminants
such as halide salts, (sodium chloride).
It is strongly recommended to periodically inspect and
thoroughly clean crevices, weld points, under gaskets,
rivets, bolt heads, and any locations where small amounts
of liquid could collect, become stagnant, and concentrate
contaminates. 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.
Typically the most eective and ecient means for routine
cleaning of most stainless steel products is to give the
surfaces a brisk rubbing with a soft cloth soaked in warm
water and a gentle detergent, or mild mixture of ammonia.
Rubbing 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
cleaners," some may contain abrasives which could scratch
the surface, (compromising the protective chrome-oxide
lm), 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
nish.
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.
27
ENERGY SAVING TIPS
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.
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 with-
in 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
periods, 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 temperature (13°C / 55°F).
28
LONG-TERM STORAGE / WINTERIZATION
Outdoor Product Long-Term Storage /
Winterization:
1. Time to Winterize, when the daily low ambient tempera-
ture is at or below 38°F (3.3°C).
!
CAUTION
Operation of the unit at ambient temperatures below the
recommended Winterization temperature will void your
warranty.
2. Turn unit of.
3. Remove all contents.
4. If necessary, move the unit so you can gain access to
the rear of the product.
5. Unplug the unit from the power outlet.
6. It is also recommended that the power to the outlet be
turned-o if the circuit is not required for other items
during the Winter season.
7. When cleaning unit pay particular attention to any
cracks and crevices that may have accumulated dirt
and debris.
8. Remove the front toe-grille, and use a brush and
vacuum to clean dirt and debris from beneath the unit.
9. Thoroughly clean the toe-grille and re-install on the
unit.
10. Remove the rear access cover, and use a brush and
vacuum to clean dirt and debris from the machine
compartment.
11. Thoroughly clean the rear access cover and re-install
on the unit.
12. Wipe down all interior surfaces with anti-bacterial
cleaner to be followed with clean rinse water to remove
any residual chemicals which could cause staining. o
not use any abrasive cleaners or scouring pads.
13. Leave the door open and allow to completely dry out
before closing the door.
14. Thoroughly clean the door gasket with anti-bacterial
cleaner to be followed with clean rinse water to remove
any residual chemicals.
15. Thoroughly clean the exterior with a cleaner approved
for stainless steel. Do not use any abrasive cleaners or
scouring pads. See "Stainless Steel Maintenance".
16. Any mounting hardware / fasteners that are showing
signs of corrosion should be replaced.
17. Once the exterior has been thoroughly cleaned,
you may want to apply a coating of car wax to help
protect against spotting from moisture, dirt, and
debris that may accumulate on the surfaces during the
Winterization period.
18. Do not place a cover on the unit, as this can trap
condensation.
• If the plastic defrost drain pan located under the
compressor contains water, use a sponge to
remove as much water as possible.
Start-Up After Long-Term Storage:
1. If stored outside, it is recommended that the unit again
be thoroughly inspected per the storage instructions
above to address any dirt or debris from the weather
and/or animals/insects.
2. Connect the unit to electrical power.

tendency to reect normal appliance operating noises.
Listed below are common refrigeration components with a
brief description of the normal sounds they make.
Your product may not contain all the components listed.
• Compressor: The compressor makes a hum or pulsing
sound that may be heard when it operates.
• Evaporator: Refrigerant owing through an evaporator
may sound like boiling liquid.
• Condenser Fan: Air moving through a condenser may
be heard.
• Automatic Defrost Drain Pan: Water may be heard
dripping or running into the drain pan when the unit is
in the defrost cycle.
Solenoid Valves: An occasional clicking sound may be
heard as solenoid valves are operated.

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 o. 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.

THERMISTOR
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.
Both thermistors in the unit are identical. If a thermistor is
suspected of being defective, the resistance can be ver-
ied. Place the thermistor in an ice water bath, the resis-
tance 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 one (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.

DEFROST
Defrost
Outdoor units defrost every 3 hours of
compressor runtime for 40 minutes. If you have
veried that the unit does not have an ambient
air leak, utilize the Control Operation - Service
section and adjust unit to defrost every 2 hours
for 60 minutes

REMOVE FAN & COVER
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.
