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 defrost
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.
