9.15 Defrosting the refrigerator manually
NOTICE!
A
I
➤ Disconnect the power supply.
➤ Empty the contents.
➤ Put a cloth in the freezer compartment and the refrigerator to absorb any excess
water.
Never use mechanical tools to remove ice or to loosen objects stuck to
the device.
NOTE
•
The refrigerator compartment has an automatic cyclic defrost
system, which prevents excessive frost forming on the evaporator
fins. However, if the refrigerator is used for extended periods in high
humidity and/or high ambient temperature conditions, frost may
build up on the evaporator fins behind the internal fan cover, which
can reduce the cooling performance. In this case a manual defrost is
recommended.
•
The freezer compartment will require periodic manual defrosting,
recommended if the frost layer is higher than 3 mm.
➤ Leave the doors open.
✓ The condensate drains off through a hose at the back of the refrigerator and is
routed outside the vehicle.
➤ Wipe both compartments dry with a cloth.
