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.

9

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.
