In an absorption refrigerator system, ammonia is liquefied
in the finned condenser coil at the top of the refrigerator.
The liquid ammonia then flows into the evaporator (inside
the freezer section) and is exposed to a circulating flow of
hydrogen gas, which causes the ammonia to evaporate,
creating a cold condition in the freezer.
The tubing in the evaporator section is specifically sloped
to provide a continuous movement of liquid ammonia
downward by gravity through this section. If the refrigera-
tor is operated when it is not level and the vehicle is not
moving, liquid ammonia will accumulate in sections of the
evaporator tubing. This will slow the circulation of hydro-
gen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
prevent this loss of cooling. The vehicle needs to be
leveled only so it is comfortable to live in (no noticeable
sloping of floors or walls).
When the vehicle is moving, the leveling is not critical as
the rolling and pitching motion of the vehicle will pass to
either side of level, keeping the liquid ammonia from
accumulating in the evaporator tubing.

Before starting the refrigerator, check that all the manual
gas valves are in the ON position. DO NOT forget the
manual shutoff valve on the rear of the refrigerator. See
FIG. 6.
This refrigerator is equipped with a control system, which
can automatically select the most suitable energy source
which is available, either AC or LP gas operation. The
system can be set by the user to be fully automatic, or if
desired, LP gas only.

necessity of resetting each time a different energy
source is employed.
After the initial start-up, the thermostat should be
moved from "COLDEST" to the desired temperature
setting, usually about mid-setting.

4. DESCRIPTION OF OPERATING
MODES
A. AUTO MODE
When operating in the AUTO mode, the AUTO mode
indicator lamp (B) will illuminate. The control system
willautomatically selectbetweenAC andGASopera-
tion with AC having priority over GAS. Either the AC
indicator lamp (A) or the GAS indicator lamp (C) will
illuminate depending on the energy source selected
by the control system. If the control system is operat-
ing with AC energy and it then becomes unavailable,
the system will automatically switch to GAS. As soon
asACbecomesavailableagain,thecontrolwillswitch
backto ACregardless ofthestatusofGASoperation.
B. GAS MODE
When operating in the GAS mode, the AUTO mode
indicatorlamp(B)willbeoffandtheGASmodeindicator
lamp(C)willbeilluminated.ThismodeprovidesLPgas
operation only. The control system will activate the
ignition system and will attempt to light the burner for a
period of approximately 45 seconds. If unsuccessful,
the CHECK indicator lamp (D) will illuminate and the
GAS mode indicator lamp (C) will turn off.
To restart GAS operation, press the main power ON/
OFF button (1) to the OFF and then ON position. The
control system will attempt a new 45 second ignition
sequence.
If the refrigerator has not been used for a long time or
theLPtankshavejustbeen refilled, air may be trapped
in the supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1)
three or four times. If repeated attempts fail to start the
LP gas operation, check to make sure that the LP gas
supply tanks are not empty and all manual shutoff
valves in the lines are open. If the problem is still not
corrected, contact a service center for assistance.
C. STANDBY MODE OF OPERATION
This control system contains a feature where it will
continuetooperate the coolingsystemin the eventofa
failure of a major operating component. Two different
modes of operation can occur in this category.
If for some reason the display module becomes non-
functional, the control system will revert to fully auto-
matic operation – selecting the best energy source
availablewithACand GAS priority. Thetemperatureof
the refrigerator will be maintained at the MID position
withinnormaltemperaturetolerances.Thepowermod-
ule will continually attempt to reestablish operation of
the display module.
The second standby mode of operation will execute
when a failure of the temperature sensing device or
associated electronic circuitry occurs. If this should
occur, the control system will operate on the energy
source selected via the control panel. The cooling unit
willruncontinuouslyontheselectedenergysource.The
refrigerator will continue to operate in this mode indefi-
nitely or until a new sensor is installed and the system
is reset.
