INSTALLATION

GENERAL INSTRUCTIONS

The refrigerators outlined hereon have been design certified under ANS i! 21.19 Refrigerators by the American Gas Asso- ciation for installation in a mobile home or recreational vehicle and are approved 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 2223.1-l 974

2.Mobile Homes Al 19.1-l 975

3.Recreational Vehicles Al 19 2-l 975

The unit must be electrically grounded in accordance with the National Electric Code ANSI, Cl- 1978 when installed if an external alternating current electrical source is utilized.

4. Any applicable local code

In Canada

1.Standard CGA 10.1 /CSA 2240.4, gas equipped mobile housing and recreational vehicles

2.Sandard CSA 2240.61 electrical requirements for mobile housing

3.Standard CSA Z240.6.2/C22.2 No 148 electrical require- ments for recreational vehicles.

Ventilation

The installation shall be made in such a manner as to separa- te 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 dimen- sion 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 instruc- tion booklet have been certified for use with the refrigerator models listen in the tables. Certified vent system kits, see separate list. The ventilation kits must be installed and used without midification. 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 iiftout planel 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 gage.

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

ELECTRICAL CONNECTION

120 Volts A C

The refrigerator is equipped with a three prong (grounded) plug for protection against shock hazards and should be plug-

ged directly into a properly grounded three prong receptacle. Do not cut or remove the grounding prong from this p!ug 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 “Tri-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 RM 360 and RM 460.20 Amps. for RM 660.30 Amps. for RM 760 and RM 1300.

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.

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 refngerator

should	be completed with	a relay mounted either in the car or
in the	recreational vehicle	(see Fig below	) This relay will

automatically cut out the refrigerator when the car motor is stopped
