Modes of Operation
A precise heat is applied to the boiler area of the cooling unit caus-
ing a chemical reaction within the cooling unit that ultimately results
in the refrigerator cooling. The heat is applied by means of:
■
A 120 volt AC heater positioned in a heater well welded to the
surface of the boiler. AC operation requires 108 to 132 volts AC.
To replace the heater, the refrigerator must be removed from the
enclosure.
Burn hazard! Allow canister and heaters
to cool before attempting to remove and
replace.
■
A propane gas burner positioned below the boiler such that the
heat from the flame is directed across the surface of the boiler.
The controls energize the solenoid coil to open the gas valve.
Spring pressure closes the valve when the controls stop the flow
of current to the solenoid coil. The controls use an electronic
sparker to ignite the propane gas at the burner.
ATTENTION
!
