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
performed 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. Disconnect the gas supply line at
the rear of the refrigerator, see FIG. 1. Always use a
back up wrench when loosening and tightening this
connection. Cap the gas supply line, loosen the
screws anchoring the refrigerator to the enclosure
and slide the refrigerator out of the compartment.
When replacing the refrigerator make sure that the
sealing strips are properly positioned.
Replacement is the reverse of removal. Check all
connections for gas leaks.
Refer to section INSTALLATION, page 4 to 8.

PERIODIC MAINTENANCE
To keep your Dometic refrigerator operating efficient-
ly and safely, periodic inspection and cleaning of
several components once or twice a year is recom-
mended.
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.
