WATER HEATER
The water heater, which runs on 120 or 220 volt AC power, has an
ON/OFF switch at the main panel in the cabin area. A check valve in
the water heater piping prevents hot water from washing back into
the cold water source. A pressure relief valve prevents damage if
pressure or temperature gets higher than safe settings. The thermo-
stat on the water heater is preset and is not adjustable.
Note: Refer to the water heater instruction manual for safety pre-
cautions and for detailed operation, maintenance, and winterizing
instructions. In areas where frost is possible, the heater tank must
be drained to prevent possible damage during winter storage.
Before turning on power to the water heater, be sure tank is full and
water is covering the heating element. The heater tank must be kept
full of water to avoid damage to the heating elements.
REFRIGERATOR
The refrigerator/freezer is designed to operate on 120 or 220 volt
AC and/or 12 volt DC power. When the 120 or 220 volt system is
not operating, the refrigerator operates on 12 volts. A built-in relay
automatically switches to the correct power. The AC control is an
OFF/ON breaker switch at the main panel in the cabin. The unit
also has a 10 amp direct current (DC) breaker on the battery switch
panel in the engine compartment.
The power needed by the refrigerator exerts a continuous drain on
the battery when it is powered by the 12 volt DC system. It can draw
a 100 amp battery dead in a short period of time. To avoid exces-
sive battery drain, keep the temperature control at a medium setting
when air temperatures are in the 70° to 90° F range. If you plan an
overnight trip and shore power is not available, run the generator or
the engine occasionally to ensure your battery is charged.
Note: Refer to the refrigerator instruction manual for safety
precautions and for detailed operation and maintenance
instructions. The manual is in your owner’s packet.
MICROWAVE OVEN
The microwave oven is controlled by an electronic touch control
panel. The breaker at the main panel must be on in order to use the
microwave. For a detailed description of the microwave oven fea-
tures see the owner’s manual supplied by the manufacturer.
