MAINTENANCE & SERVICE

The user should be aware of service that must be
done on a regular schedule to keep the refrigerator
operating properly. The service should only be per-
formed by a qualified technician who is familiar with
LP gas systems and refrigerators.

1. REFRIGERATOR REMOVAL

Before working on the refrigerator, make sure the AC
voltage and DC voltage leads are disconnected. Shut
off the gas supply at the LP tank. Disconnect the gas
supply line at the rear of the refrigerator, see FIG. 1.
Always use a back up wrench when loosening and tight-
ening connections.
Cap the gas supply line, loosen the screws anchoring
the refrigerator to the enclosure and slide the refrigera-
tor out of the compartment.
When replacing the refrigerator make sure that the seal-
ing strips are properly positioned.
Replacement is the reverse of removal. Check all con-
nections for gas leaks.
Refer to section INSTALLATION, page 4 to 8.

2. PERIODIC MAINTENANCE

To keep your Dometic refrigerator operating efficiently
and safely, periodic inspection and cleaning of several
components once or twice a year is recommended.

A. 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 obstruc-
tions such as bird/insect nests, spider webs, etc.
Clean the coils on the back of the refrigerator. Use a
soft bristled brush to dust off the coils.

It is important to keep the refrigerator area free from
combustible material, gasoline and other flammable
vapors or liquids.

NOTE: The following maintenance is required once or
twice a year, but should only be done by a qualified ser-
viceman who is familiar with LP gas systems and refrig-
erators.
