Installation and Owner’s Manual 24
Upper fl ap (A) may have already been installed as a ventilation baffl e. See also section entitled “Install the Lower and
Upper Vents”, Step 3.
The sealing area must be separated air-tight from the living area.
If the combustion seals are not being used or fail to seal properly in the unit, use a different kind of sealing
to keep hazardous combustion gases out of the living area of the vehicle. If the seal is not complete,
exhaust fumes can be present in the living area of the vehicle. The breathing of exhaust fumes can cause
dizziness, nausea, or in extreme cases, death.
NOTICE
WARNING
!
AC Operation, 120 volts AC voltage (132 volts max. - 108 volts min.)
DC Operation, 12 volts DC control voltage (15.4 volts max. - 10.5 volts min.)
This refrigerator operates on these electrical sources. Operation out of these limits may damage the refrigerator’s electrical circuit
parts and will void the warranty.
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 clearance 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 fi re.
Connect the 120 volts AC supply
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.
Plug the AC power cord(s) 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(s) does not touch the burner cover, the fl ue 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. The voltage drop decreases the output of the system heater and causes
poor cooling performance.
If you use an incorrect wire size and/or fuse size, electrical fi re can result.
1. Determine the min. wire size and the max. fuse size to use:
- Measure the distance from the vehicle battery to the refrigerator.
- If the distance is 0 - 20 feet, use a minimum of 10 AWG wire and a maximum 30 Amp fuse.
- If the distance is over 20 feet, use a minimum of 8 AWG wire and a maximum 40 Amp fuse.
- If the wire size is larger than the min. size, use the correct fuse per RVIA A119.2 standard or local codes.
