MAINTENANCE OF YOUR REFRIGERATOR
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, benzene,
gasoline, or thinner. These tend to leave scratches on the coat-
ing.
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.
Defrosting
Set the On-Off switch to "OFF". When frost is melted, wipe the
compartment plates with a soft, dry cloth. A better suggestion is to
set the dial to "1" before you retire for the night. The frost will be
gone the next morning.
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
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 3 for the suggested dual-battery wiring diagram.
You will note that in this diagram there are 2 separate battery
sources. One source is the vehicle or car battery used exclusively
for the operation of the engine and accessory equipment such as
head lights. The other source is for the operation of the DC appli-
ances 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.
