About Your Refrigerator - Norcold 3163 Installation And Operating Instructions Manual

Notice: On initial start-up, it may take longer for
the burner to light because of air being
purged from the gas supply line.
Important Note: Altitude above 4000 feet affects the
performance of the gas burner, could reduce cool-
ing performance of the refrigerator, and may cause
nuisance burner outages. Norcold recommends
that the refrigerator be switched to AC or DC elec-
tric at an altitude above 4000 feet. An optional high
altitude kit is available through your dealer for gas
operation at altitudes up to 10,000 feet.
4. Set thermostat to desired temperature setting.
Notice : Cleaning vehicle exterior by a power
(car) wash may allow water to enter
the refrigerator's burner area through the
vent cap. Operate the refrigerator on
gas to ensure evaporation of any mosi-
ture that may have entered the burner
area.
AC Operation
1. Press mode selection button (C).
2. Set the thermostat (B) to the coldest setting.
Allow to operate at coldest setting for 6 to 8 hours
before adjusting.
DC Operation
1. Press mode selection button (D). There is no
need to set thermostat to any setting. The DC
operation is a continuous run (no thermostat
control) mode.
Shut-Down: All Modes
1. Place the mode selector button to the off position.
This will interrupt all AC and DC power and stop
operation of the refrigerator.

Leveling
The Norcold refrigerator does not require critical lev-
eling. Normal vehicle leveling to provide comfort for the
vehicle occupants is satisfactory for refrigerator operation.
Operation in Transit
While the refrigerator should be level when the vehicle
is stationary, performance during transit is not normally
affected.
Ventilation Fan
A thermostat controlled mechanical fan is used to
move air across the refrigerator's cooling system. The
thermostat is calibrated to activate the fan whenever
the vehicle's interior temperature reaches 85 degrees
or higher.
When leaving the vehicle unattended, it is advisable
to leave windows or roof exhaust vents open to main-
tain the vehicle's interior temperature below 85 de-
grees. This will allow the refrigerator to operate efficiently,
minimize fan operation, and limit current draw from the
battery.
Information Regarding Battery Drain
A 12 volt DC source is required for the gas and DC
modes of operation and the mechanical fan which
assists the air flow across the refrigerator's cooling
system. For gas operation, the DC power source
supplies voltage for electronic ignition (100 milliamps)
and to the mechanical fan (240 milliamps). The cur-
rent draw is 340 milliamps. This indicates that drain
on the battery is very low and has little effect on
"battery run down". For DC operation, the DC power
source supplies voltage for the cartridge heating ele-
ment. The DC operation draws approximately 11.7
amps at 12 VDC and 13.6 amps at 14 VDC. It is
evident that current draw for DC operation is high,
therefore, the refrigerator should not be operated for
long periods of time from a battery only without a
means of recharging the battery. The DC voltage
should be checked while operating the refrigerator in
the DC mode. The voltage at the refrigerator should
never be below 11.5 volts DC.
Fresh Food Compartment
This compartment is designed to store and cool foods.
Refrigeration requires air circulation within the fresh
food compartment. Restriction of air circulation will
cause inadequate refrigerator temperatures and possi-
ble food spoilage. Do not cover the refrigerator shelf
with paper or plastic.
To prevent food odors, store highly flavored foods in
covered dishes, plastic bags or wrap in foil. Cover
vegetables to retain crispness.
To reduce frost formation on the cooling fin, cover liquids
and moist foods. Do not put hot foods into the refrigerator
or let door remain open longer than necessary.
Allow the refrigerator to operate for a minimum of eight
hours or overnight before loading the refrigerator with
food. Loading a warm refrigerator with warm foods will
