Cleaning Cabinet and Door
Wipe with a soft, dry cloth. To remove dirt, use a cloth mois-
tened by a warm neutral detergent solution. Never use hot water.
After cleaning, wipe with a dry cloth.
CAUTION: Never use a brush, powder soap, cleanser, acid, ben-
zene, gasoline, or thinner. These tend to leave
scratches on the coating.
Gasket (door cushion)
Wipe away dirt with a soft cloth moistened by a neutral deter-
gent. Do not soak the cloth excessively. If water gets inside, the
insulating effect may become temporarily impaired.
Attachments
Wash all attachments in soap suds. Rinse and wipe clean with a
dry cloth.
To Turn Off The Refrigerator
If you will not be using the refrigerator for a day or two, turn the
thermostat knob to "1". For a longer period, set the On-Off switch
to "OFF" and disconnect power by removing the AC plug from it's
socket. Also, disconnect the DC power from it's source.
When not in use, the refrigerator should be emptied, cleaned,
and dried, and the door left ajar.
Drip Tray
The drip tray is located beneath the evaporator plate (See Fig-
ure 14). The tray can be emptied by either pulling it forward and
removing it, or by removing the drain plug while holding a pan
below.
For installations where the refrigerator door cannot be opened
beyond 90 degrees, the drain plug must be utilized to empty the
tray prior to removal for cleaning.
To remove the tray, pull forward until the tray drops down. Tilt
the front of the tray down to allow tray to be removed. Re-install
in reverse order.

Defrosting
Remove food contents and set the On-Off switch to the "Off"
position. When frost has melted, wipe the compartment plates
with a soft dry cloth and remove excess water from drip pan.
Do not use sharp objects to chip ice from the cooling plates.
Information on battery power
The battery power required for the operation of the refrigerator
is dependent upon the number of DC appliances being used, the
MAINTENANCE OF YOUR REFRIGERATOR
type of operation desired and cycling pattern desired.
A battery must also be sufficiently charged to prevent overdraw.
A battery is rated usually in ampere-hours; that is, it is capable
of sustaining it's rated ampere capacity for a period of one hour.
If the total amperage load of the vehicle is high (25 amperes),
then the installation of a 72 ampere-hour battery will not provide
the required power for any length of time unless it is aided by a
recharging source such as an alternator or generator.
Various load requirements of the vehicle's DC system dictate
the ampere-hour capacity that should be installed.
Refer to Figure 15 for the suggested dual-battery wiring dia-
gram. You will note that in this diagram there are 2 separate bat-
tery sources. One source is the vehicle or car battery used exclu-
sively for the operation of the engine and accessory equipment
such as head lights. The other source is for the operation of the
DC appliances within the recreational vehicle or boat. This battery
source is referred to as the accessory or house battery and is
used solely for that purpose.
Both of these battery sources are charged by one alternator or
generator which is powered by the vehicle engine. This charging
device should be of adequate amperage rating so that a short
engine run will bring the batteries up to full charge. The standard
alternator has a minimum rating of 60 amperes.
Check your voltage regulator or cut-out for correct charging
level. Voltage should be 13.5 to 14.5. volts to the battery.
Important Points Regarding Battery-Powered
Sources
The dual battery switch or battery isolator is an important com-
ponent as it permits the alternator or generator to charge both
the accessory battery and the vehicle battery during operation of
the vehicle engine. However, it limits the current draw of the DC
appliances to the accessory battery source when the engine or
vehicle is idle or stopped. Thus it assures that the vehicle battery
is fully charged for starting the engine. The batteries referred to in
Figure 15 are two 6 volt golf cart batteries connected in series to
provide 12 volts. Golf cart batteries are suggested for the follow-
ing reasons:
1. Larger plate construction.
2. Deep draw characteristics.
3. High ampere-hour rating.
The standard golf cart battery has a rating of approximately
185-205 ampere-hours. When two of these batteries are con-
nected in series, the result is 12 volt DC at 185 or 205 ampere-
hour capacity.
The DC supply to the refrigerator is connected to the negative
post of one battery and to the positive post of the other battery.
The power converter or solid state battery charger shown in Fig-
ure 15 is an essential item for battery-operated systems.
The converter is operated on 120 volt AC and should have an
output rating of 12.6-l4.5 volts DC at approximately 20-50 ampere
capacity. During 120 volt operation, the converter is used to
charge the batteries and to operate the DC appliances. It has the
capacity to operate items such as lighting, water pumps, exhaust
fans, and sanitary facilities while maintaining or charging the bat-
teries. Charging rate varies from 5-20 amperes per hour.
The Norcold dual voltage refrigerator automatically switches
from AC to DC or from DC to AC. When a power supply of 120
volts AC is connected to the vehicle, the voltage selection relay is
energized and disconnects the unit from DC operation. This
unique feature assures 120 volt operation when available and per-
mits the power converter to concentrate it's charging facilities to
the batteries or to other DC appliances.
When the AC supply is disconnected, the refrigerator automat-
ically reverts to DC operation. Setting the On-Off switch to the
"OFF" position will prevent operation on AC or DC.
