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.
