REFRIGERATOR OVERVIEW
ABSORPTION COOLING SYSTEM
When turning on the refrigerator, you should ad-
just the thermostat (excludes RM2351, RM2451,
RM2551, DM2652 & DM2852 - not adjustable) to
the coldest temperature setting. The cooling cycle
may require an extended running time before cool-
ing 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 oor 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 efciency (or rat-
ing) at high altitude This is a direct result of lower atmos-
pheric 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.
PURGING AIR FROM THE LINES
If the refrigerator has not been used for a long time - or -
the LP tanks have just been relled, 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 ame 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.
WHEN THE REFRIGERATOR IS NOT
IN USE
Any absorption refrigerator that is to be taken out of ser-
vice for an extended period of time should be turned off.
It is important that you do not leave the refrigerator
to run idle and/or unattended for days or weeks.
AUTOMATIC ENERGY SELECTOR
SYSTEM
The refrigerator is equipped with an automatic energy se-
lector system. The user turns the refrigerator on and then,
the refrigerator automatically selects the most suitable en-
ergy source available, 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).
On 3-way models, the control system can manually be set
to DC mode (DC operation). The DC mode overrides all
other operating modes.
The refrigerator controls will work down to 9.6 VDC.
