A. INSTALLATION

The refrigerator must be installed in a substantial enclosure and must be level. When installing the refrigerator in the enclosure, all areas within the recess in which the refrigerator is installed must be sealed from the living space.

Make sure that there is a complete seal between the front frame of the refrigerator and the top, sides and bottom of the enclosure. A length of sealing strip is applied to the rear surface of the front frame for this purpose, see FIG. 4. The sealing should provide a complete isolation of the appliance's combustion system from the vehicle interior.

Note: Be careful not to damage the sealing strip when refrigerator is put in place.

B. SECURING REFRIGERATOR IN ENCLOSURE

The refrigerator is installed in the enclosure with eight screws. Six screws are in the front frame and two are in the plate on the rear. See FIG. 5.

FIG. 5

(2) Screws (3) Screws on each side of frame

NOTE: Push refrigerator into enclosure until front frame is tight against the cabinet. First, secure the frame to cabinet with six screws. Second, install the two screws to the floor at the rear of the refrigerator.

Failure to follow the sequence in securing the refrigerator in the enclosure can cause leakage between the frame and cabinet. Any space between the counter, storage area or ceiling and top of the refrigerator should be blocked. The heat produced at the rear of the refrigerator will become trapped in this space, making the top of the refrigerator hot and reducing the efficiency.

The dimensions shown in FIG. 3 will give you adequate space for service and proper installation.

8. GAS CONNECTION

Hook-up to the gas supply line is accomplished at the manual gas shutoff valve, which is furnished with a 3/8" SAE (UNF 5/8" - 18) male flare connection. Always use a backup wrench when connecting the gas supply line to the gas inlet fitting. All completed connections should be checked for leaks with a noncorrosive leak detector. (See FIG. 6 - Gas inlet fitting may have a different orientation than shown).

! WARNING

DO NOT use a flame to check for gas leaks.

FIG. 6 GAS INLET FITTING

The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than 13.5 inches water column, static (no load).

LP GAS CYLINDER PRESSURE REGULATOR TO REFRIGERATOR

When testing the gas supply system at test pressures in excess of 1/2 psig, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing the gas supply system at pressures less than or equal to 1/2 psig, the appliance must be isolated from the gas supply piping by closing its individual manual shutoff valve.

In case detailed instructions on the installation and connection to the gas supply are required, contact your dealer or distributor.

9. TESTING LP GAS SAFETY SHUTOFF

The gas safety shutoff must be tested after the refrigerator is connected to LP gas supply.

To test the gas safety shutoff, proceed as follows:

A. Start the refrigerator according to the instructions for LP Gas Operation. See "Section C. Operation Instructions."
B. Check that the gas flame is lit. Allow it to burn a few minutes to ensure a full, stable flame.
C. Turn the gas safety valve (D, FIG. 8) to the "OFF" position. Within 1-2 minutes the gas safety device within the valve should automatically close. An audible "click" from the valve may be heard.
D. Turn the gas safety valve to the "ON" position (D, FIG. 8).
E. Without pushing in the knob (D, FIG. 8) of the gas safety device, apply a commercial leak detection solution to the burner jet. No bubbles should appear. Bubbles indicate a gas leak and the safety valve must be replaced by a qualified serviceman.
F. Rinse the burner jet with water. Light the burner and allow it to burn for five minutes.

10. 120 VOLT AC ELECTRICAL CONNECTION

The refrigerator is equipped with a three-prong (grounded) plug for protection against shock hazards, and should be plugged directly into a properly grounded three-prong receptacle. DO NOT cut or remove the grounding prong from this plug. The power cord should be routed to avoid direct contact with the burner cover, fuel cover or manual gas shutoff valve knob.

11. 12 VOLT DC CONNECTION

The 125 watt heating element operates the cooling unit when the refrigerator is connected to the battery of the vehicle. It has a current rating of about 10.5 amps; therefore, the wiring from the battery to the refrigerator must be of heavy enough gauge to carry this load satisfactorily without undue voltage drop. To ensure this, the minimum size of wire to be used is 14 A.W.G. The terminal block for connecting the 12V supply cable to the battery is positioned at the lower lefthand corner of the rear side (G, FIG. 8). From this terminal, the connection to the battery should be made using ring-type clamps with tightening bolts to ensure good contact with the battery terminals. Polarity is not important, therefore it does not matter which wire leads to which battery terminal.

DO NOT connect lights or any other electrical components to the same circuit that is used by the refrigerator.

IMPORTANT:

To prevent the refrigerator from being left on and draining the battery when the vehicle's engine is not running and charging the battery, it is recommended that an automatic cutout relay be installed between the battery and the refrigerator toggle switch so that the refrigerator will not draw current when the vehicle ignition is switched off. Alternatively, a suitable plug and receptacle should be installed in the 12V supply line so that the refrigerator can be disconnected from the supply, as necessary.

FUSE

A 12 amp (continuous rating) fuse should be incorporated in the wiring of the DC supply, as near to the battery as possible. The fuse must be in the side of the wiring which is not connected to the chassis. For example, if the vehicle has a negative ground, the fuse must be in the positive side of the wiring.

12. CHANGING DOOR HINGES FROM ONE SIDE TO THE OTHER

If required, the door hinges can be moved to the opposite side. Reverse the door hang in the following way:

A. Unscrew the upper hinge pin, taking care not to lose the set of washers and bushings.
B. Lift the door from the lower hinge pin. If decorative door panel is to be installed, proceed to Step 13.
C. Unscrew the pin and mount it on the opposite side hinge.
D. Unscrew the travel catch and mount it on the opposite side.
E. Replace door on lower hinge pin. Replace upper hinge pin and bushings removed in Step A.
F. Check that the door closes properly and seals all around.

13. INSTALLATION OF DECORATIVE DOOR PANEL

The door panel can easily be mounted. The dimensions of the panel must be:

Height 19-3/4"

Width 17-27/32"

Thickness Up to 1/8"

Weight 49 lbs.

A. Remove the door. See Section 12.
B. Remove the lower trim molding. (NOTE: Trim molding is not installed on new units in cartons)

SECTION C. OPERATING INSTRUCTIONS

1. IMPORTANCE OF LEVELING A REFRIGERATOR

In an absorption refrigerator system, ammonia is liquefied in the finned condenser coil at the top of the refrigerator. The liquid ammonia then flows into the evaporator (inside the freezer section) and is exposed to a circulating flow of hydrogen gas, which causes the ammonia to evaporate, creating a cold condition in the freezer.

The tubing in the evaporator section is specifically sloped to provide a continuous movement of liquid ammonia downward by gravity through this section. If the refrigerator is operated when it is not level and the vehicle is not moving, liquid ammonia will accumulate in sections of the evaporator tubing. This will slow the circulation of hydrogen and ammonia gas, or in severe cases, completely block it, resulting in a loss of cooling.

Remember to level the vehicle when stopping for more than an hour, otherwise the cooling unit could be permanently damaged due to overheating if it is left "ON".

When the vehicle is moving, the leveling is not critical as the rolling and pitching motion of the vehicle will pass to either side of level, keeping the liquid ammonia from accumulating in the evaporator tubing.

2. CONTROLS

The gas and electric controls are located at the rear of the refrigerator and are accessible through the lower vents in the outside wall of the vehicle. See FIG. 8.

3. OPERATING INSTRUCTIONS

A. LP GAS OPERATION

After initial installation, servicing, or changing gas cylinders, etc., the gas line may contain some air which should be allowed to escape by briefly turning on the refrigerator or other gas appliances. This will ensure that the flame lights immediately. See FIG. 8 for control location and identification.

1) Open the shutoff valve of the gas bottle. Check that there is enough gas. Open any on-board shutoff valve which is in the gas line to the refrigerator.
2) Open the lower vent at the rear of the refrigerator on the outside of the vehicle, and switch the electrical toggle switches A and B to the "OFF" position.
3) Turn the gas thermostat control (F) to the highest setting.
4) Depress the knob (D) of the flame failure device, turn it to position "ON", and hold it down while depressing the piezo igniter button (E) several times in quick succession (a click should be heard each time it is depressed).
5) Keep the knob depressed for a further 10-15 seconds.
6) Release the knob and check for flame by looking through the opening in the metal burner cover.
7) If the burner has not lit, repeat the lighting procedure. If the burner fails to light within a couple of attempts, contact a qualified technician or your dealer.

NOTE: The refrigerator has a flame failure device which will automatically shut off the gas to the burner if the flame is blown out. While the knob (D) is being held in, this device is temporarily inoperative.

8) If the ambient temperature is above 80^ F and/or the door of the refrigerator is opened frequently the knob (F) should be left in higher position.
9) To terminate gas operation, turn knob (D) to the "OFF" position.

DO NOT attempt to operate the refrigerator by both gas and electricity at the same time. Always ensure that one method of operation is turned off before using the alternate energy source.

! WARNING

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 possible 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.

In the case of the RM4223, the refrigerator works continuously on DC operation (no thermostat control).

On AC operation, the temperature is controlled by a thermostat. 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 compartment, 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 frozen food. The internal volume of the refrigerator is 2,5 cubic feet, net.

Avoid using large dishes and do not stack food or food containers too closely as this interferes with the circulation 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.

! CAUTION

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.

E. CLEANING

Cleaning the refrigerator is usually done after it is defrosted or put into storage. To clean the interior of the refrigerator, use lukewarm water and a mild dishwashing detergent. Use only warm water to clean the finned evaporator, 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, cleaned 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 refrigerator, 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 components once or twice a year is recommended.

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 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 appearance 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.

C. Examination and Cleaning of Flue, Burner and Jet

Once or twice a year, look through the opening (see FIG. 9) in the burner box and examine the appearance of the burner flame which should be predominantly blue in color when the gas thermostat knob is set to its highest position. (Refer to FIG. 10).

If this is not the case, clean the flue, burner, jet, etc. (see section D and E).
