Connect the Propane Gas Components
Connect the Electrical Components
AC Operation 120 volts AC voltage
(132 volts max. - 108 volts min.)
12 volts DC control voltage
(15.4 volts max. - 10.5 volts min.)
This refrigerator operates on these electrical sources. Opera-
tion out of these limits may damage the refrigerator’s electrical
circuit parts and will void the warranty.
WARNING: The rear of the refrigerator cooling system
has hot surfaces and sharp surfaces that can damage
electrical wiring. Make sure that there is a good clear-
ance between all electrical wiring and the cooling system
of the refrigerator. Position any electrical wiring within the
refrigerator enclosure opposite the burner side of the
refrigerator. Do not put any electrical wiring through the
roof exhaust vent. Failure to correctly position electrical
wiring can result in electrical shock or fire.
Connect the 120 volts AC supply:
WARNING: Connect the AC power cord(s) only to a
grounded three-prong receptacle. Do not remove the
round ground prong from any of the AC power cords. Do
not use a two prong adapter or an extension cord with
any of the AC power cords. Operation of the refrigerator
without correct ground can cause dangerous electrical
shock or death if you are touching the metal parts of the
refrigerator.
Put the AC power cord(s) into a grounded three-prong recep-
tacle:
- Make sure the receptacle is positioned within easy reach of
the lower intake vent.
- Make sure the power cord(s) does not touch the burner
cover, the flue pipe, or any hot component that could
damage the insulation of the power cord.
Connect the 12 volts DC supply:
As the distance from the vehicle battery to the refrigerator
increases, the correct AWG wire size and fuse size also
increases. If the wire size is too small for the distance, a
voltage drop occurs.
1. Determine the min. wire size and the max. fuse size to use:
WARNING: If you use an incorrect wire size and/or fuse
size, electrical fire can result.
- Use a minimum of 18 AWG wire and a maximum 6 Amp
fuse.
- If the wire size is larger than the min. size, use the correct
fuse per RVIA A119.2 standard or local codes.
2. Install a fuse in DC power supply wires between the battery
and the refrigerator:
- Put fuse as close to the battery as possible.
3. Connect the DC power supply wires (See Art00966):
- Attach a 1/4 inch Quick Connect terminal to each DC power
supply wire.
NOTE: Do not use the chassis of the refrigerator or the
vehicle frame as one of the conductors. Attach the
DC power supply wires only to the battery and the
power board [1] of the refrigerator.
- Push the positive DC power wire [2] onto the power board
terminal that is marked 12VDC.
- Push the DC ground wire [3] onto the power board terminal
that is marked GND.
- Make sure each DC power supply wire is on the correct
polarity terminal.
This refrigerator operates on propane gas at a pressure of 11
inches Water Column Propane.
The controls operate on 12 volts DC (10.5 volts min. - 15.4 volts
max.). Operation out of these limits can damage the refrigerator
electrical circuit parts and will void the warranty
- Flush the water supply line until the water is clear.
- Put the tubing into the adapter [5] until it is against the stop
of the adapter.
- Tighten the compression nut by hand (hard finger tight).
- Using two wrenches, tighten the compression nut 1 ½ to 2
turns.
- Open the water shut off valve of the vehicle.
- Examine the connections for leaks.
