Section D. Maintenance & Service

E. CLEANING

Cleaning the refrigerator is usually done after it is defro- sted or put into storage. To clean the interior of the refri- gerator, use lukewarm water and a mild dishwashing detergent. Use only warm water to clean the finned eva- porator, gaskets, ice trays and shelves. NEVER use strong chemicals or abrasives to clean these parts as the protective surfaces will be damaged. It is important to always keep the refrigerator clean.

F. SHUTOFF (STORAGE PROCEDURE)

Place the toggle switches for DC and AC operation to the "OFF" position or turn the gas valve to position "OFF", as applicable. See FIG. 8.

When not in use, the refrigerator should be emptied, cle- aned and dried and the door left open so that fresh air can circulate inside.

The travel latch placed in the second hole will hold the door ajar and allow air to circulate.

! CAUTION

DO NOT store explosive substances in the refrigera- tor, such as cigarette lighter gas, petrol, ether or the like.

TIPS FOR THE SERVICE TECHNICIAN

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, or removing the refrigerator, make sure the electrical supply (AC and DC) is turned OFF before leads are disconnected. Shut off the gas supply. Disconnect and cap the gas supply line. Loosen the screws anchoring the refrigerator to the enclosure and slide the refrigerator out of the compartment.

Replacement is the reverse of removal. Check all connections for gas leaks.Refer to Section A, Item 1 through 13 of Installation Instructions.

2. PERIODIC MAINTENANCE

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

A. It is important to keep the area at the back of the refri- gerator clean. Check the lower vent, upper vent and area between these openings for any obstructions such as bird/insect nests, spider webs, etc. Clean the coils on the back of the refrigerator. Use a soft brist led brush to dust off the coils..

NOTE: AVOID SPRAYING WATER THROUGH THE REFRIGERATOR VENTS WHEN WASHING THE RV.

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

B. Check all connections in the LP gas system (at the back of the refrigerator) for gas leaks. The LP gas supply must be turned on. Apply a noncorrosive bubble solution to all LP gas connections. The appea rance of bubbles indicates a leak and should be repaired immediately by a qualified serviceman who is familiar with LP gas systems and refrigerators.

! WARNING

DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
