12 Volts DC Connection

All refrigerator models require a 12
volt DC supply (even though 2-Way
models are designed to operate on
120 volts AC and gas, a 12 volt DC
control is required to perform control
functions in Gas and AC Modes. The
DC lead connections (1/4" male quick
connects) are at terminals located on
the Power Supply at the rear of the
refrigerator. One connection
marked positive (+ ) and the other
negative (-). Correct polarity must be
observed when connecting to the DC
supply. Connect two wires at the re-
frigerator and route to the DC supply.
The distance the current must travel
from the battery to the refrigerator
dictates the AWG wire size to be
used. Should the wire be too small
for the distance, a voltage drop will
result. In the case of 3-Way models,
the voltage drop affects the wattage
output of the system heater and re-
sultant refrigerator performance.
See the wire and fuse chart (Table
1) for the correct wire and fuse size.
Electrical Connection
120 Volts AC
The refrigerator is equipped with a
three-prong plug for protection
against shock hazard and must be
connected into a recognized three-
prong attachment receptacle. The
free length of cord is 24" and there-
fore is recommended that the re-
ceptacle be located to the left side
of the refrigerator (viewed from rear)
and approximately 12" from the
floor. This allows easy accessibility
through the vent door. The cord
must be routed so as not to come in
contact with the Burner cover, flue
pipe, or any other component that
could damage the cord insulation.
WARNING
DO NOT REMOVE
GROUNDING PRONG FROM THE
REFRIGERATOR AC
CORD. REMOVAL OF
PRONG CAN RESULT IN A SEVERE ELECTRICAL SHOCK, AS WELL AS,
VOIDING THE REFRIGERATOR ELECTRICAL CERTIFICATION AND WAR-
RANTY. EXTENSION CORDS ARE NOT RECOMMENDED.
