Be aware of possible safety hazards when you see the safety
alert symbol on the refrigerator and in this manual. A signal word
follows the safety alert symbol and identies the danger of the
hazard. Carefully read the descriptions of these signal words to
fully know their meanings. They are for your safety.
This signal word means a hazard, which if ignored, can cause
dangerous personal injury, death, or much property damage.
This signal word means a hazard, which if ignored, can cause
small personal injury or much property damage.
Model No. and Serial No.
The model and serial number are on a label which is inside the refrigerator on the
left side and on the cover of this manual.
Operation
This refrigerator is made for refrigerating purposes and operates on 120/220/240
VAC or 12/24 VDC power when installed as written in this manual. The correct
supply voltage(s) is located on the serial plate.
AC is the primary power source. When an AC source is not available, a built-in relay
automatically switches the refrigerator operation to the DC power source. If the
refrigerator is operating on the DC power source and AC power becomes available,
the relay switches the refrigerator operation to the AC power source.
Never store combustible materials near the refrigerator.
Storing combustible materials near the refrigerator creates a
safety hazard and also decreases the ventilation of the cooling
system which decreases the refrigerator performance.
Do not store explosive substance such as aerosol cans with
ammable propellant in this appliance.

WARNING
!
Do not touch the evaporator or other metal parts inside the
refrigerator cabinet with wet hands because they can freeze to
the refrigerator.
Always disconnect all power sources from the refrigerator
when doing routine maintenance. Have service work done only
by a qualied service technician.
This refrigerator can be used by children aged 8 years and
above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have
been given supervision or instruction concerning use of
the refrigerator in a safe way and understands the hazards
involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be done by children
without supervision.
Avoid using ammable sprays near the refrigerator. The
electric contacts may catch re.
When there is a leak of utility gas around you, do not touch the
refrigerator or its cable plug. Open the windows and maintain
good ventalation. Failing to do so may lead to a re and or a
burn from the explosion.
Do not use the refrigerator if its power cable is damaged or
the catch of its plug is loose. Failing to comply may lead to an
electric shock, short or re.

5
Check if the voltage noted on the type plate on the refrigerator
matches the one applied by an external power source.
The refrigerator temperature is controlled by a thermostat, located in the
refrigerator. A light, located on the panel comes on when the refrigerator is “ON”.
Number “1” is the warmest and number “5” is the coldest thermostat position. For
efcient operation, change the thermostat according to the types of food stored and
the ambient temperature.
If you are not going to use the refrigerator for an extended period of time, put the thermostat
to the “OFF” position (full counterclockwise position).
Protection System
Your refrigerator has an over current protection system in the electronic circuit to
prevent damage to the inverter which may occur due to a reverse polarity connection.
If the refrigerator does not operate and the interior light does not come on, check
the fuse, which is located on the side of the inverter case, and the polarity of the DC
power supply. If the refrigerator still does not operate, another problem can exist in the
inverter. Have an authorized Norcold Service Center check the refrigerator.
Cleaning and Defrosting
Defrosting
It is normal for frost to collect on the freezer plate inside the refrigerator. Excess frost
decreases the cooling performance of the refrigerator. Defrost the refrigerator as
necessary.
Do not use sharp objects, a hair dryer, a heat gun, etc.
to defrost the refrigerator. Damage to the interior of the
refrigerator can occur.
- Turn the thermostat to “OFF”.
- Remove all food from the refrigerator.
Defrosting the refrigerator makes excess water inside the refrigerator.
- Put dry towels (etc.) inside the refrigerator to absorb the excess water.
- Put trays of hot water in the freezer until the frost is melted.
- Empty the drip tray.
- Remove the wet towels (etc.) and dry the inside of the refrigerator

Cleaning
- Turn the thermostat to the desired setting.
- Put the drip tray and all food in the refrigerator.
A good time to clean the refrigerator is just after you defrost it.
Clean the inside of the refrigerator as often as necessary to avoid food odors:- Remove
all food from the refrigerator.
Do not use abrasive cleaners, chemicals, or scouring pads because
they can damage the inside of the refrigerator.
- Wash the inside of the refrigerator and the door gasket with a solution of liquid dish
detergent and warm water.
- Rinse with clean water and dry.
- After cleaning, put a thin coating of petroleum jelly on the hinge side of the gasket to
keep it soft and to prevent it from rolling.
Battery Maintenance
Over cooling drains your battery
When the ambient temperature is between 70° and 90° F, keep the thermostat at the “3“
position to avoid an excessive drain of the battery. When making ice, or storing frozen
foods, turn the thermostat to the coldest setting “5“.
Maintain the battery
If the charge of your battery is not sufcient, the cooling performance of your refrigerator
decreases.
Only use a “quick charger” on the battery if the thermostat is
turned to “OFF”.
NOTICE
CAUTION

Check the Battery charge Level
A fully charged battery will have a specic gravity reading of between 1.260 and 1.280.
The battery voltage is best indicated when the refrigerator is “ON” and the battery
charging system is “OFF”. Charge the battery when the specic gravity reading is less
than 1.200.

Ventilation
Sufcient ventilation (airow) over the rear mounted condenser of the refrigerator
is necessary for the refrigerator to operate correctly. Use any of the following
combinations of vent openings: A-D, A-I, A-J, B-C, B-F, B-H, C-D, C-I, C-J, D-F, D-H,
F-I, F-J, G-I, G-J, H-I, H-J (See Art01129 - for 0788 models only).
For the minimum required ventilation, each individual vent opening should be no less
than 50 square inches. However, the vent openings should be larger, to allow as much
ventilation as possible. The more air that circulates over the refrigerator condenser, the
more efciently the refrigerator will operate.
