6.2 External Wiring
120 Volts AC Connection(s): The refrigerator is equipped
with a three prong (grounded) plug for protection against
shock hazards and should be plugged directly into a
properly grounded three prong receptacle. DO NOT cut
or remove the grounding prong from this plug. Units with
icemaker may have a separate plug.
SECTION 7 LP GAS REQUIREMENTS
The LP gas pressure to the refrigerator should be 11 inch-
es water column with half of all BTU’s of the RV turned
on. With all other appliances off, the pressure to the re-
frigerator should not exceed 12 inches water column. To
check the gas pressure when the refrigerator is operating,
there is a pressure test port below the solenoid valve as-
sembly.
SECTION 8 LP GAS COMPONENTS
8.1 Manual Gas Shutoff Valve
The manual shutoff valve is a non-serviceable part. The
valve is part of the solenoid valve assembly. It is rare to
have problems with the manual shutoff or the solenoid
assemblies. If you have checked gas pressure and it is
low, check pressure at input line. If pressure is 11 inches
at input and low at the pressure test port change solenoid
valve assembly. The valve is not opening all the way.
DO NOT use a ame to check for gas leaks.
TESTING LP GAS SAFETY SHUTOFF
The gas safety shutoff must be tested after the refrigera-
tor is connected to the LP gas supply.
To test the gas safety shutoff, proceed as follows:
1. Start the refrigerator according to the instructions, and
switch to GAS mode.
2. Check that the gas ame is lit and the GAS mode indi-
cator lamp is on.
3. Close the manual gas shutoff valve at the back of the
refrigerator.
4. Wait for six to seven minutes for unit to go into ame
failure after three tries. LP is ashing (message alternates
between LP and the temperature). Indicates gas opera-
tion lockout.
12 Volt DC Connection(s): The connection is made to the
terminal block marked 12 volts DC. The control system is
connected to a battery/converter circuit and could draw
up to 5 amps at 12 volts DC. The refrigerator must be
connected to the battery circuit with two wires of adequate
capacity to avoid voltage drop. Proper polarity is crucial
for refrigerator operation. Don’t use the chassis for the
ground circuit. A loose connection will create erratic op-
eration on gas and AC. The wires to the power source
must/should be a dedicated circuit. No other electrical
equipment or lighting should be connected to refrigerator
circuit.
For models equipped with the automatic lock:
The refrigerator requires the connection of a signal wire
from the alternator (D+) in order to maintain the automatic
door travel latch and temporary gas lockout function. The
vehicle’s alternator (D+) is connected to D+ on the termi-
nal block.
