Dometic RM 4223 - Manual (Page 9)

B. ELECTRIC OPERATION
12V DC / 120V AC OPERATION
In the case of the RM4223, the refrigerator works conti-
nuously on DC operation (no thermostat control).
On AC operation, the temperature is controlled by a ther-
mostat. The thermostat knob (C, in FIG. 8) should be set
to position 4-5 in normal working conditions. If the
ambient temperature is high and/or fresh food is put into
the refrigerator you may set the refrigerator to a higher
setting.
If you wish a higher temperature in the cooling compart-
ment, set the knob to a lower position.
3. TO TERMINATE ELECTRIC OPERATION
To terminate electric operation, turn switches (A and B)
to the "OFF" position.
NOTE: NEVER OPERATE THE REFRIGERATOR ON
MORE THAN ONE ENERGY SOURCE AT A TIME.
4.HOW TO USE THE REFRIGERATOR
A. FOOD STORAGE COMPARTMENT
The storage compartment is completely closed and
unventilated, which is necessary to maintain the required
low temperature for food storage. Consequently, foods
having a strong odor or those that absorb odors easily
should be covered. Vegetables, salads, etc. should be
covered to retain their crispness. The coldest positions in
the refrigerator are under the cooling fins and at the
bottom of the refrigerator. The warmer areas are on the
upper door shelves. This should be considered when
placing different types of food in the refrigerator.
The refrigerator is designed for the storage of fresh
foods, milk, etc. It is not intended for the storage of fro-
zen food. The internal volume of the refrigerator is 2,5
cubic feet, net.
NEVER PUT HOT FOOD INTO THE REFRIGERATOR.
Avoid using large dishes and do not stack food or food
containers too closely as this interferes with the circulati-
on of cold air within the cabinet.
If possible, start the refrigerator on gas or AC the day
before it is to be used, to allow time for the interior to be
cooled. It is then preferable to load the refrigerator with
food which has been precooled in your household
refrigerator, or in the market.
Before moving the vehicle, make sure that all containers
are tightly covered to avoid spills. If required, crumpled
paper may be packed between bottles and other items to
prevent shifting while traveling.
Engage the travel catch at the top of the front corner of
the door before moving the vehicle.
B. DEFROSTING
To defrost, take out any food, etc. then turn off the gas
valve or switch of the DC/AC supply to the refrigerator.
Leave the refrigerator door open and place a suitable
dish or other receptacle under the evaporator to catch
the defrost water.
When all the frost has melted, any remaining drops of
water in the refrigerator should be wiped up with a clean
cloth.
DO NOT use a hot air blower. Permanent damage
could result from warping the metal or plastic parts.
DO NOT use a knife or an ice pick, or other sharp
tools to remove frost from the freezer shelf.

Most LP gas appliances used in recreational
vehicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is possi-
ble that the gasoline fumes could enter this type
of appliance and ignite from the burner flame,
CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, it is recommended that all LP
gas appliances which are vented to the outside
should be shut off when refueling.
The refrigerator must be shut off during refueling.
