stopping at a refueling
station.

(Check LP gas.)
ABSORPTION COOLING SYSTEM
When turning on the refrigerator, you should adjust
the thermostat to the coldest temperature setting.
The cooling cycle may require an extended running
time before cooling effect is observed.
LEVELING THE REFRIGERATOR
Leveling is one of the requirements for proper operation
with absorption refrigerators. To ensure proper leveling the
vehicle needs to be leveled so it is comfortable to live in
(no noticeable sloping of floor or walls).
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to al-
low proper cooling.
When the vehicle is moving, the leveling is not critical, as
the rolling and pitching movement of the vehicle will pass
to either side of level, keeping the liquid ammonia from
accumulating in the evaporator tubing.
OPERATING REFRIGERATOR AT HIGH
ALTITUDE
All gas appliances experience lowered efficiency (or
rating) at high altitude This is a direct result of lower
atmospheric pressure and oxygen levels, and is not a
defect of the refrigerator.
Reduced cooling performance and burner outage may
occur at altitudes higher than 5500 feet above sea level
(while operating on LP gas). Always operate refrigerator
on electric power at altitudes higher than 5500 feet.
AUTOMATIC ENERGY SELECTOR
CONTROL SYSTEM
The refrigerator is equipped with an automatic energy
selector control system. The user turns the refrigerator on,
selects the desired temperature, and then the refrigerator
automatically selects the most suitable energy source avail-
able (either 120 VAC or LP gas operation). The system can
be set by the user to be fully automatic (AUTO mode is
selected) or to operate on LP gas only (AUTO mode is off).
The refrigerator controls will work down to 9.6 volt DC.
PURGING AIR FROM THE LINES
If the refrigerator has not been used for a long time - or -
the LP tanks have just been refilled, air may be trapped in
the supply lines. To purge the air from the lines, turn the
refrigerator off and on by pressing the ON/OFF button. If
the flame is not lit within 45 seconds, turn the refrigerator
off and back on again. This procedure can be repeated 3 to
4 times. If repeated attempts fail to start the LP gas opera-
tion, check to make sure that the LP gas supply tanks are
not empty and that all manual shutoff valves in the lines
are open. If the problem persists, turn the refrigerator off
and take it to a Service Center.
