INSTALLATION

GENERAL INSTRUCTIONS

This appliance is designed for storage of foods and storage of frozen foods and maklng ice.

The refrigerators outlined hereon have been design certified under ANS 221.19 -- 1983. Refrigerators by the American Gas Association for installation in a mobile home or recreational vehicle and are appproved by the Canadian Gas Association.

The certifications are, however, contingent on the installation being made in accordance with the following instructions as applicable.

The installation must in the USA conform with:

1.National Fuel Gas Code ANSI Z223.1-1 984

2.Manufactured Home Construction and Safety Standard, Title 24 CFR, Pan 32-80,

3.Recreational Vehicles ANSI/NFPA No. 501 C-1977

The unit must be electrically grounded in accordance with the National Electric Code ANSI/NFPA No. 70-1984 when installed if an external alternating current electrical source is utilized.

4. Any applicable local code

The installation must in Canada conform with

1.Current CGA B 149 Gas Installation Codes

2.Current CSA Standard Z 240.4 GAS - EQUIPPED RECREATIONAL VEHICLES AND MOBIL HOUSING

3.Any applicable local code

The unit must be electrically grounded in accordence with the current CANADIAN ELECTRICAL CODE C 22 Parts 1 and 2.

Ventilation

The installation shall be made in such a manner as to separate the combustion system from the living space of the mobile home or recreational vehicle. Openings for air supply or for venting of combustion products shall have a minimum dimension of not less than 1/4 inch.

Proper installation requires one lower fresh air intake and one upper exhaust vent. The ventilation kits shown in this instruction booklet have been certified for use with the refrigerator models listed in the tables. Certified vent system kits, see separate list. The ventilation kits must be installed and used without modification. An opening towards the outside at floor level in the refrigerator compartment must be provided for ventilation of heavier-than-air fuel gases. The lower vent of the recommended kits is provided with proper size openings. The flow of combustion and ventilating air must not be obstructed.

For ready serviceability of the burner and control manifold parts of the refrigerator the lower side vent is fitted with a liftout panel which provides an adequate access opening.

GAS CONNECTION

Hook-up to the gas supply line is accomplished at the manual gas valve, which is furnished with a 3/8" SAE (UNF 5/8- 18) male flare connection. All completed connections should be checked for leaks with soapy water.

The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than 11 inches water column.

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 or equal 1/2 psig the appliance must be isolated from the gas supply piping system 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.

ELECTRICAL CONNECTION

120VoltsAC

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 cord should be routed to avoid coming in contact with the burner cover flue cover or other hot components.

Refrigerator models requiring 12 V DC

supply

On units provided with interior light or automatic reigniter or both there is one additional terminal block marked “12 V”. On “Three Power” units with interior light or automatic reigniter or both there are two additional blocks.

The refrigerator must be connected to the battery circuit with two wires of adequate capacity to avoid voltage drop. The wire gage should be chosen with consideration to the wire length in accordance with table below. The 12 V circuit must be fused. Maximum circuit fuse size: 15 Amps. for the models RM2300 and RM2400, 20 Amps. for RM2500, 30 Amps. for RM2600 and 40 Amps. for RM2800.

Do not use the body or chassis of the vehicle as a substitute for either of the two conductors. No other electrical equipment or lighting should be connected to the refrigerator circuit. The refrigerator will draw from 10 to 23 Amps at 12 Volt depending on model.

The interior light and the reigniter must be connected to a separate battery circuit and will draw about 1 Amp.

Maximum two conductor wire length in feet and meter.

6	ft.	69	64	49	34	31	135
4	ft.	110	102	79	55	50	220

CAUTION

Do not Operate the refrigerator on 12 Volt when the vehicle is parked. YOU will run out of battery in a rather short time.

If possible the installation of a 12 Volt operated refrigerator should be completed with a relay mounted either in the car or in the recreational vehicle (see below). This relay will automatically cut out the refrigerator when the car engine is stopped.

SPECIAL HINTS

Note. Do not install the appliance directly on carpeting. Carpeting must be protected by a metal or wood panel beneath the appliance which extends at least full width and depth of the appliance.

The refrigerator must be installed in a substantial enclosure and must be level. A spirit level is supplied with each refrigerator and by placing it in the freezer compartment one can level the refrigerator both ways front to back and side to side. When installing the refrigerator in the enclosure care should be taken to ensure a complete sealing between the front frame of the refrigerator and the top, sides and bottom of the enclosure. For this purpose a length of sealing strip is applied to rear surfaces of the front frame. A sealing strip should also be applied to the foremost floor of the enclosure as shown in fig 8. The sealing strip should provide a complete isolation of the appliance combustion system from the vehicle interior.

Be careful not to damage the sealing strip applied to the floor of the enclosure when the refrigerator is put in place.

In the front frame and in the base at the rear of the refrigerator there are holes for screws for fixing the refrigerator in the enclosure. See fig. 9.

Any space between counter or storage area and the top of the refrigerator greater than 1 1/2" should be blocked. The heat produced at the rear of the refrigerator will otherwise become trapped in this space making the top of the refrigerator hot and reducing the efficiency of the refrigerator.

TO REMOVE AND REPAIR THE REFRIGERATOR

Before working on the refrigerator, make sure that 120 V A.C. and optional 12 V DC. Leads are disconnected. Close the gas valve. Unscrew the hexagon nut (#11 Fig. 2) and move the Valve on the gas line out of the bracket. Check that the valve slips out of the clip connection with the switch shaft.

Loosen the screws fixing the refrigerator to the enclosure and remove the refrigerator.

When replacing the refrigerator make sure that the sealing strips are properly positioned. After reassembly the gas connection should be checked for leaks.

TEST OF THE GAS SAFETY SHUTOFF

The gas safety shutoff device must be tested after the refrigerator is placed in operation.
