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.

DO NOT store explosive substances in the refrigera-
tor, such as cigarette lighter gas, petrol, ether or the
like.
SECTION D. MAINTENANCE & SERVICE
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.
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
