Operation
Thisrefrigerator is made for refrigerating purposesand operates on220/240 voltsAC
and12/24 volts DC power supplyieswheninstalledas written in thismanual.
NOTE: The refrigerator operates automatically onAC or DC power. When both
power sources are supplied to the refrigerator, it defaults toAC. When the
refrigeratoris disconnected from the shoreline power (whenACpoweris
nolonger available), therefrigeratorswitches to DCoperation.
CAUTION: Neverstore combustible materials near therefrigerator. Storing
combustiblematerials near therefrigerator creates asafety hazard andalso
decreasesthe ventilation ofthe cooling systemwhichdecreases the refrigerator
performance.
Donottouchtheevaporatororothermetalpartsinside the refrigerator cabinet with
wethands because they can freezetothe refrigerator.
Alwaysdisconnect all power sources from therefrigerator when doing routine
maintenance.Have service workdone only bya qualified servicetechnician.
Therefrigerator temperature is controlled byathermostat, locatedonthe panelabove the
door. Agreen power 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
efficient operation, change the thermostat according to the types of food stored and the
ambienttemperature.
If you are not going to use the refrigerator for an extended period of time, put the thermo-
stat to the “OFF” position and open the door so the latch pin is in the storage position.
(SeeArt01520).

Protection System
Yourrefrigeratorhas an over currentprotection
systemin the electronic circuit toprevent damage to
theinverter which may occur duetoa reverse polarity
connection.
If the refrigerator does not operate and the green
power light does not come on, check the fuse,
which is located on the side of the inverter case, and
thepolarityofthe DC power supply. Ifthe refrigerator
stilldoes not operate, another problemcan exist in
theinverter. Have an authorizedNorcold Service
Centercheck the refrigerator.
Cleaning and Defrosting
Defrosting
Itis normal for frost to collecton the freezer plate inside therefrigerator. Excess frost
decreasesthe cooling performance of therefrigerator. Defrostthe refrigerator as neces-
sary.
CAUTION: Do not use sharp objects, a hair dryer, a heat gun, etc. to defrost the
refrigerator. Damage to theinteriorof the refrigerator can occur.
- Turn the thermostat to “OFF”.
- Removeallfood from the refrigerator.
NOTE: Defrostingthe refrigerator makesexcess water inside therefrigerator.
- Putdry towels (etc.) inside the refrigerator toabsorbthe 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
- Turn the thermostat to the desired setting.
- Put the drip tray and all food in the refrigerator.

Cleaning
Agood time to clean the refrigerator is just after you defrost it.
Cleanthe inside of the refrigerator as oftenas necessary to avoid food odors:
- Removeallfood from the refrigerator.
NOTE: Donot use abrasive cleaners, chemicals, or scouring pads because they can
damagethe inside of therefrigerator.
- Wash the inside of the refrigerator and the door gasket with a solution of liquid dish
detergentand 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
Ifthe charge of your battery is notsufficient, the coolingperformanceof your refrigerator
decreases.
CAUTION: Only use a “quick charger” on the battery if the thermostat is turned to
“OFF”.
Check the Battery charge Level
Afullychargedbattery willhave a specificgravity reading ofbetween 1.260and1.280. The
batteryvoltage isbestindicated when the refrigerator is“ON”and the battery charging sys-
temis “OFF”. Charge the battery when the specific gravityreadingis less than 1.200.

Installation
Therefrigerator should be located and secured on a solid surface in the vehicle.
Beforeinstalling therefrigeratorinto the opening, make surethe DC supply is properly
connected. In many cases, the DC supply can be connected from outside the vehicle
by means of the baggage or access door.
Measurethe opening to determineif you have proper clearancefor installation.
Additionalinsulation spacearoundthe refrigerator isnotnecessary.
For your reference
The wiring diagram shown below is recommended for dual battery hookup (See
Art01516).

Be sure the refrigerator is not in direct sunlight or near a gas stove, a heater, or other
heat-generatingappliances. Avoidinstallingyour refrigerator closeto warm waterlines
or warm air ducts.
Yourrefrigeratorwas thoroughly cleaned beforeshipment from the factory.
Itis advisable, however, to cleantheinterior once more before using. Wipethe interior
with a cloth and warm water. Then wipe with a dry cloth.
Ventilation
Sufficientventilation (airflow) overtherear mounted condenserofthe refrigerator is
necessaryfor the refrigerator tooperate correctly (SeeArt01582).
* NOTE: The fan will operate only when
theambient temperature is
higherthan approximately 95° F.
CAUTION: Do not remove the
bottomrails from therefrigerator
cabinet. Therails supply space
underthe refrigerator that is neces-
saryfor correctventilation.
If you do not make sure that the
ventilationis correct,ashortened

Connect the 220/240 volts AC and 12 volts DC supplies
This refrigerator operates on 220/240 volts (50 hertz)AC current and 12/24 volts DC
currentfrom a battery.
CAUTION: Onlyconnect the refrigerator directly to the battery. Because they
oftengeneratehigh voltagepulsesand cause transistor defectsinthe inverter, no
otherswitches, lead wires, orelectrical equipment should share thewiring between
the refrigerator and battery. Do not use an extension cord.
When using either a converter or a battery charger, make sure that they are connected in
parallelbetween the battery and the refrigerator. Donot use a converter or battery charger
to supply the DC power directly to the refrigerator because these two devices do not
supplyfiltered DC power (SeeArt01521).
Asthe distancefromthe vehicle battery to the refrigeratorincreases,the correctAWG wire
sizealso increases. If he wire size istoosmall for the distance,a voltagedrop occurs.
Thevoltage dropdecreasesthe cooling performance of therefrigerator.
1. Norcold recommends that you use the following wire and fuse sizes:
- Measurethe distancefromthe vehicle battery to therefrigerator:
- If the distance is less than 12 feet, use 16AWG wire and a 10Amp fuse.
- If the distance is between 12 and 20 feet, use 14AWG wire and a 10Amp fuse.
- If the distance is more than 20 feet, use 12AWG wire and a 10Amp fuse.
