OPERATING

INSTRUCTIONS

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, 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.

OPERATION

Before starting the refrigerator, check that all the manual gas valves are in the ON position. DO NOT forget the manual shut off valve on the rear of the refrigerator see FIG. 1.

This refrigerator is equipped with an automatic energy selector system and an auto defrosting control system. The energy selector system will automatically select the most suitable energy source that is available, either 120-volt AC, or LP gas operation. The system can be set by the user to be fully automatic, or if desired, LP gas only.

The defrost system will automatically carry out defrost in frozen food and fresh food compartment once per 24 hours. To be able to control the performance of the de- frost intervals the system is equipped with a built in real time clock.

The clock has to be set to local time at the very first start up of the refrigerator or when the 12-volt DC supply has been disconnected for a longer period of time.

A message on the LED panel will alert when the clock needs to be set.

! WARNING

Most LP gas appliances used in recreational ve- hicles are vented to the outside of the vehicle. When parked close to a gasoline pump, it is pos- sible that the gasoline fumes could enter this type of appliance and ignite from the burner flame, CAUSING A FIRE OR AN EXPLOSION.

FOR YOUR SAFETY, when refueling, shut off all LP gas appliances which are vented to the out- side.
