1. OPERATING INSTRUCTIONS A E D OFF ON FUEL SELECTOR Safe FLAME PUSH WHEN LIGHTING THERMOSTAT IMPORTANCE OF LEVELING A REFRIGERATOR In an absorption refrigerator system ammonia is lique fied 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 If the refrigerator is operated when it is not level and the ve hicle is not moving liquid ammonia will accumulate in sections of the evaporator tubing This will slow the cir culation of hydrogen 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 floor or walls When the vehicle is moving the leveling is not critical a2. ee FIG 9 2 Turn the knob A to position marked AC for 230 240 volt AC operation 3 Turn the thermostat knob B to position 4 4 To shut off the refrigerator turn the knob A to OFF position 12 V OPERATION Only operate your refrigerator on 12V when the engine of the vehicle is running otherwise your battery will soon be discharged 1 Turn the knob A to the position marked DC for 12 volts operation 2 Note there is no thermostat function on 12 V DC operation the refrigerator works continuously 3 To shut off the refrigerator turn the knob A to OFF position REGULATING THE TEMPERATURE The refrigerator is equipped with a thermostat that can be adjusted by turning the knob B to different setting to maintain the desired cabinet temperature At OFF In gas operation the thermostat closes its main valve and the burner runs continuously at the bypass rate just enough to keep the burner lit In electrical operation the contacts in the ther mostat are open and the heating elements are off At MAX In gas operation the thermostat allows the burner to remain on high flame continuously In electric operation the heating element is ON continuously Lowest cabinet and freezer tem peratures are obtained at this setting The thermostat can be adjusted between MAX and OFF to obtain the desired cabinet temperature The closer the knob is to MAX the colder the cabinet tempera
