Defrosting
Over time, frost forms on the freezing surfaces. Because
it reduces freezer efficiency, this must not be allowed to
build up.
Check the freezer element regularly every week.
If the frost is 3 mm thick or thicker, the refrigerator must be
defrosted.
When defrosting:
• Turn off the refrigerator.
• Remove all foodstuffs and ice trays from the refrigerator.
• Leave the doors slightly open.
Do not attempt to speed up defrosting with any form of
heating apparatus. This can damage the refrigerator's
plastic surfaces. Similarly, sharp objects must not be used
to scrape ice away.
The melt water from the freezer element runs from a col-
lection channel, through a pipe, to a bowl at the back of
the refrigerator (from where it normally evaporates).
With heavy frosting and a lot of melt water, lift the drainage
hose out of the bowl (accessible from the vehicle's exte-
rior, via the ventilation grille) and let the water run from the
hose down into a suitable container.
After defrosting, put the hose back into the bowl. Use a
rag to dry up melt water from the freezer compartment.
When all the ice has melted, dry the refrigerator.
Foods may now be placed in the refrigerator, but do not
try to make any ice until the refrigerator has become cold
again.
NB!
Layers of ice must not be removed using
force.
Defrosting must not be speeded up by the
use of heat sources.
Important!
If the refrigerator is not to be used for some time,
the cut-off valve in the motorhome and the valve
on the gas bottle must be closed.

Cleaning the refrigerator
Clean the refrigerator regularly.
1 Turn off the refrigerator.
2 Clean the refrigerator's interior with water and a mild,
unperfumed washing-up liquid.
Do not use strong chemicals or abrasives.
Never use cleaning agents, scouring powder, stron-
gly perfumed products or wax polishes to clean the
refrigerator's interior. These can damage the surfaces
or leave strong odours.
3 Clean the refrigerator's exterior with a damp rag and a
mild cleaning agent.
4 Clean the door seals with a soap solution. Wipe them
dry.
5 Use a brush to clean the element at the back of the
refrigerator. Ensure that the refrigerator is turned off
when cleaning the element.
If the refrigerator is not working
Check the following before calling in a service technician:
1 That the refrigerator is level.
2 If it is possible to start the refrigerator using any of the
connected energy sources.
3 If the refrigerator is not working on bottled gas, check
that:
• there is enough gas in the bottle.
• the gas valves are open.
4 If the refrigerator is not working on 12 V, check that:
• the vehicle's headlights are on.
• the 12 V fuse has not blown.
5 If the refrigerator is not working on 230 V, check that:
• the 230 V supply is connected to the refrigerator.
• the 230 V fuse has not blown.
If the refrigerator is not cold enough, this may be because:
1 The thermostat is set incorrectly.
2 Too much (hot) food has been placed in the refrigerator
at one time.
3 The door is not properly closed or the door seals are
defective.
4 The freezer element is frosted up.
5 The ventilation is insufficient due to the grille being
obstructed or the winter hatch throttling the air supply.
6 The ambient temperature is too high (e.g. because the
ventilation openings are in an awning enclosed area).
If the refrigerator still does not work normally, contact a
service technician.
