LOW AMBIENT CONTROL
All RV absorption refrigerators, while similar, operate a
little differently than your home refrigerator. Dometic de-
signers and engineers have equipped your refrigerator
with an exclusive feature that allows for trouble-free op-
eration in low ambient temperature (like below 50°F) for
extended periods of time. Simply turn on the low ambi-
ent switch located beneath the top decoration panel that
houses the control panel (see figure 2, "D"). Once the
outdoor temperature is above 50°F, the low ambient
switch should be turned off.
ELECTRIC EQUIPMENT

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
refrigerators.
1. REFRIGERATOR REMOVAL
Before working on the refrigerator, make sure the AC
voltage and DC voltage leads are disconnected.
Loosen the screws anchoring the refrigerator to the
enclosure and slide the refrigerator out of the com-
partment.
When replacing the refrigerator make sure that the
sealing strips are properly positioned.
Replacement is the reverse of removal.
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 sev-
eral 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.
