PRODUCT CARE

DEFROSTING
1. Shut off the refrigerator by turning the knob A to
"OFF" position.
2. Empty the refrigerator, leaving the drip tray under
the finned evaporator.
3. Leave the cabinet and freezer doors open. Filling
the ice tray with hot water and placing it on the
freezer shelf can reduce defrosting time.
Defrost water
Defrost water runs from the drip tray to a recepta-
cle at the rear of the refrigerator where it nor-
mally evaporates. With a lot of defrost water as a
result of heavy frosts build up on the cooling fins,
remove the drip tray and turn it around. Replace
the drip tray with the outlet on the right side of the
drip tray and put a bowl under the outlet.
Do not use:
• A knife or an ice pick, or other sharp tools
to remove frost from the freezer shelves. It
can create a leak in the ammonia system.
• A hot air blower. Permanent damage could
result from warping the metal or plastic
parts.
4. When the ice has melted, dry the interior of the
refrigerator with a clean cloth.
5. Replace the drip tray to its original position and
connect the draining tube.
6. Replace all food and set the thermostat to "MAX"
for a few hours. Then reset the thermostat to the
desired setting, usually at mid-setting.
CLEANING THE REFRIGERATOR
Always keep the refrigerator clean. Cleaning the refrigera-
tor is usually done after it is defrosted or put into storage.
To clean the interior liner of the refrigerator, use lukewarm
weak soda solution. Use only warm water to clean the finned
evaporator, gasket, ice tray and shelves.
Note! Never use strong chemicals or abrasives to clean these
parts, as the protective surfaces will be damaged.
It is important to keep the area at the back of the refrigerator
clean. Check the lower vent, upper vent and area between
these openings for any obstructions such as bird/insect nests,
spider webs, etc. Clean the coils on the back of the refrigera-
tor. Use a soft bristled brush to dust off the coils. Keep the
refrigerator area free from combustible material, gasoline and
other flammable vapours or liquids.
CAUTION
MAINTENANCE & SERVICE
Service and maintenance must be done on a regular schedule to
keep the refrigerator operating properly, efficiently and safely.
The service should only be performed by a qualified
or gas technician.

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:
1. Unplug the refrigerator power cord from the 230-
240 volt AC outlet. Disconnect the 12 V DC power
to the refrigerator.
2. Remove the refrigerator from the enclosure.
3. Disconnect the heater leads at the top of the refrig-
erator.
4. With a pair of pliers, unfold the lug holding the lid
of the boiler casing and open the lid.
5. Remove some insulation wool so that the heater is
accessible.
6. Turn and lift the heater out of its pocket.
7. Fit the new heater into the pocket.
8. Reconnect the heater leads at the top.
9. Put back the insulation and close the lid of the
boiler.
10. Reinstall the refrigerator in the enclosure.
11. Check all connections for gas leaks.
12. A qualified gas fitter should be employed
13. Connect 230-240V
14. Reconnect or turn on the 12 V DC power.

PERIODIC MAINTENANCE

This work should be made by a qualified service man.
CHECKING THE CONNECTIONS
Check all connections in the ULP gas system (at the back of
the refrigerator) for gas leaks. The ULP gas supply must be
turned on. Apply a non-corrosive bubble solution to all ULP
gas connections. The appearance of bubbles indicates a leak
and should be repaired immediately by a qualified
CHECKING THE ULP GAS PRESSURE
The ULP 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 ULP gas
pressure is at the test port just ahead of the burner jet.
