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 only to a
grounded three-prong receptacle. Do not remove the
round ground prong from the power cord. Do not use a
two-prong adapter or an extension cord. 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 into a grounded three-prong receptacle:
- Make sure the receptacle is positioned within easy reach of
the lower intake vent.
- Make sure the power cord does not touch the burner cover,
the flue pipe, or any hot component that could damage the
insulation of the power cord.
- Make sure the travel latch engages the travel latch plate.
- If not, loosen the screw and adjust the height of the
travel latch plate.
- Tighten the screw.
Connect the 12 volts DC supply (3-way models only):
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. The voltage drop decreases the output of
the system heater and causes decreased cooling performance.
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.
- Measure the distance from the vehicle battery to the
refrigerator:
- If the distance is 0 - 20 feet, use a minimum of 12 AWG
wire and a maximum 20 amp fuse.
- If the distance is more than 20 feet, use a minimum 10
AWG wire and a maximum 30 amp fuse.
- If the wire size is larger than the min. size, use the correct
fuse per RVIA A119.2 standard or local codes.
The wire connections must be clean, tight and free of corrosion.
If any of these items are not correct:
- A voltage drop to the refrigerator will occur.
- The voltage drop will reduce the cooling performance of the
refrigerator.
The terminals for connecting the DC power supply are marked
positive (+) and negative (-) on the terminal block of the refrig-
erator. Make sure that:
- Each DC power supply wire is attached to the correct
polarity terminal.
- The chassis or the vehicle frame is not used as one of the
conductors.
- The DC power supply wires including the fuses are routed
directly from the battery to the refrigerator.
2. Connect the D.C. power supply wires:
- Attach a 1/4 inch female Quick Connect terminal to each DC
power supply wire.
- Push each power wire onto the terminal block [1] at the rear
of the refrigerator (See Art01254).
- Make sure each DC power supply wire is on the correct
polarity terminal.
