MAINTENANCE & SERVICE
REPLACING THE HEATER
The refrigerator is equipped with two electrical heaters, one
for 230-240 VAC and one for 12 V DC.
To replace the heater proceed as follows:
Unplug the refrigerator power cord from the 230-
240 volt AC outlet. Disconnect the 12 V DC power
to the refrigerator.
Remove the refrigerator from the enclosure.
Disconnect the heater leads at the top of the refrig-
erator.
With a pair of pliers, unfold the lug holding the lid
of the boiler casing and open the lid.
Remove some insulation wool so that the heater is
accessible.
Turn and lift the heater out of its pocket.
Fit the new heater into the pocket.
Reconnect the heater leads at the top.
Put back the insulation and close the lid of the
boiler.
Reinstall the refrigerator in the enclosure.
Check all connections for gas leaks.
Connect 230-240 V power cord to the outlet.
Reconnect or turn on the 12 V DC power.
PERIODIC MAINTENANCE
Checking the connections
Check all connections in the LP gas system (at the back of
the refrigerator) for gas leaks. The LP gas supply must be
turned on. Apply a non-corrosive bubble solution to all LP
gas connections. The appearance of bubbles indicates a leak
and should be repaired immediately by a qualied service-
man.
Checking the LP gas pressure
The LP gas pressure should be checked and the main regula-
tor readjusted if pressure is incorrect. The correct operating
pressure is 2,7 kPa. The correct place to measure the LP gas
pressure is at the test port just ahead of the burner jet.

Cleaning the ue and burner
Inspect the ue bafe. It should be reasonably clean and free
of soot. Heavy soot formation indicates improper functioning
of the burner.
The ue and burner both require cleaning in the following
manner:
Unplug the refrigerator power cord from the 230-
240 V AC outlet. Disconnect or shut off the 12 V
DC power to the refrigerator.
Close the gas valve by turning the knob A to
“OFF”.
Remove cover from the burner housing.
Disconnect the wire from the high voltage elec-
trode.
Remove the burner mounting screw and remove
the burner assembly.
Lift out the wire and ue bafe from the top of
ue tube.
Clean the ue from the top using a ue brush.
Blowing compressed air into the ue will not prop-
erly clean soot and scale out of the ue tube.
Replace the ue bafe.
Clean burner tube with a brush.
Blow out burner with compressed air.
Before removing burner jet, clean burner area of
soot and scale that fell out of ue tube.
Remove the burner jet. Soak the jet in wood alco-
hol and blow out with compressed air. Reinstall
and tighten burner jet.
Reinstall burner, being careful that the end of the
burner ts into the slot on the burner bracket.

Do not use a wire or pin when cleaning the
burner jet as damage can occur to the
precision opening. This can cause damage to
the refrigerator or create a re hazard.
WARNING
!

Service and maintenance must be done on a regular schedule to keep the refrigerator operating properly, efciently and safely.
The service should only be performed by a qualied technician who is familiar with LP gas systems and refrigerators.
