ABSORPTION COOLING SYSTEM
In an absorption refrigerator system, ammonia is liquefied in the finned condenser coil at the top rear 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.
When starting this refrigerator for the very first time, the cool­ing cycle may require up to four hours of running time before the cooling unit is fully operational. The tubing in the evapora­tor section is specifically sloped to provide a continuous move­ment of liquid ammonia, flowing downward by gravity through this section.
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 refrig erator operating, the vehicle should be leveled to prevent this loss of cooling.
If the refrigerator 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 hy­drogen and ammonia gas, or in severe cases, completely block it, resulting in a loss of cooling.
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 available (either 120 V AC 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.
MODES OF OPERATION - AUTO AND GAS
AUTO mode
When the refrigerator is in AUTO mode, it automatically uses the most efficient energy source that is available for operation. Should a more efficient energy source become available during operation, the refrigerator controls change from the current energy source to the more efficient energy source as follows:
-
AC operation (if 120V AC is available). AC operation is
1. only possible in AUTO mode.
GAS operation (if 120V AC is not available).
2.
GAS mode (manual LP gas operation)
When AUTO mode is turned off, the refrigerator uses gas as energy source - even if AC is available.
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 THE REFRIGERATOR
FIRE HAZARD. Before lighting the gas burner, after that the RV has not been used for some time, please check that the gas path between the burner jet and the burner tube has not been obstructed. Failure to heed this warning could cause a fire resulting in personal injury
FIRE OR EXPLOSION HAZARD. When refu­eling or parked near gasoline pumps, shut off all LP gas appliances. Failure to heed this warning could cause a fire or explosion resulting in death or severe personal injury.

WARNING
!
OPERATING THE REFRIGERATOR
STARTUP
Before starting the refrigerator:
Check that all the manual gas valves are in the ON position.
Make sure that a continuous 12V DC supply is available for
• the electronic control to function.
To start the refrigerator:
Press the ON/OFF button.
1.
2.
Select operation mode:
AUTO mode (AC and GAS)
Press the AUTO/GAS mode selector button (if not already on).
GAS mode (gas operation only)
Press the AUTO/GAS mode selector button to turn off the AUTO mode (if not already off).
STORAGE COMPARTMENTS
ADJUSTING THE THERMOSTAT
The thermostat controls both the gas and electric operation. Thus it is not necessary to reset each time a different energy source is employed. The adjustable thermostat ranges from 1 - 5 where 5 signifies the coldest temperature setting. After the initial start-up, adjust the thermostat by pressing the TEMP. SET button repeatedly until the desired setting is displayed.
TURNING OFF THE REFRIGERATOR
The refrigerator may be shut off while in any mode of opera­tion by pressing the main power ON/OFF button (OFF position). This shuts off all DC power to the refrigerator, in­cluding the interior light.
If the refrigerator will not be in operation for a period of weeks, it should be emptied, defrosted, cleaned and the doors left ajar. The ice trays should also be dried and kept outside the cabinet.
EXPLOSION HAZARD. Never store explosive substances in the refrigerator, such as cigarette lighter fuel, gasoline, ether or the like. Failure to heed this warning could cause an explosion resulting in death or severe personal injury.

FOOD STORAGE COMPARTMENT
Cool the refrigerator before placing any food inside. Never
• put hot food or drinks into the refrigerator - cool them first.
The food storage compartment is completely closed and
• unventilated, which is necessary to maintain the required low temperature for food storage. Consequently, foods hav­ing a strong odor or those that absorb odors easily should be covered.
Vegetables, salads etc. should be covered to retain their
• crispness.
The coldest positions in the refrigerator are under the cool-
• ing fins and at the bottom of the refrigerator. The warmer ar­eas are on the upper door shelves. This should be considered when placing different types of food in the refrigerator.
Arrange all food in the unit to allow for free air circulation.
• Do not overpack because a stuffed refrigerator must work harder and will have higher cabinet temperatures.
Do not leave the unit’s door open any longer than necessary.
• This will reduce frost formation and increase the efficiency of the refrigerator.
FROZEN FOOD STORAGE COMPARTMENT
This compartment is not designed for deep or quick freezing of food.
To prevent food from drying out, keep it in covered dishes,
• containers, plastic bags or wrapped in aluminum foil.
Meat or fish, whether raw or prepared, can be stored in the
• frozen food storage compartment provided they are pre­cooled first in the refrigerator. They can be stored about three times longer in the frozen food compartment as com­pared to the fresh food compartment.
Quick frozen soft fruits and ice cream should be placed in
• the coldest part of the compartment, which is at the bottom of the aluminum liner.
Frozen vegetables, may be stored in any part of the compart-
• ment.
To prevent frost buildup, which can reduce the efficiency,
• wipe excess moisture off items being placed in the compart­ment.
Ice cubes
Ice cubes can be made in the freezer compartment. Place the trays in direct contact with the bottom of the freezer compart­ment. Ice will be made more rapidly if f the thermostat is set at its highest position, but be sure to move the thermostat back to normal setting when the ice is formed; the refrigerator might otherwise become too cold.
