INSTALLATION

GENERAL INSTRUCTIONS

The refrigerators outlined hereon have been de- sign certified under ANS Z 21.19 Refrigerators by the American Gas Association 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.

The installation must in the USA conform with:

1.National Fuel Gas Code Z223.1-1974

2.Mobile Homes A119.1-1972

3.Recreational Vehicles A119.2-1970

The unit must be electrically grounded in accor- dance with the National Electrical Code ANSI, CI- 1968, when installed if an external alternating current electrical source is utilized.

4.	Any applicable local code
In	Canada
1.	Standard CGA lO.l/CSA 2240.4 gas equipped
	mobile housing and recreational vehicles
2.	Standard CSA Z240.6.1 electrical requirements
	for mobile housing
3.	Standard CSA Z240.6.2/C22.2 No 148 electrical

ELECTRICAL CONNECTION

115 Volts A C

The refrigerator is equipped with a three prong (grounded) plug for protection against shock hazard and should be plugged directly into a properly grounded three prong recept- acle. 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 com- ponents.

12 Volts VDC optional for certain models

On "Tri-Pover" units there is an additional terminal block marked "12 V". The refrigera- tor 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 the following tabel: The 12 V circuit must be fused with an appropriate fuse.

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 di- mension of not less than l/4 inch.

Proper installation requires one lower fresh air intake and one upper exhaust vent. The ventila- tion kits shown in this instruction booklet have been certified for use with the refrigerator mo- dels listed in the tables. 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 opening.

For ready serviceability of the burner and con- trol manifold parts of the refrigerator the lower side vent is fitted with a lift-out panel which provides an adequate access opening.

GAS CONNECTION

Hook-up to the gas supply line is accomplish- ed at the manual gas valve, which is furnish- ed 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 pres- sure of not more than 11 inches water gage.

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 re- frigerator circuit. The refrigerator will draw from l0-21 Amps at 12 Volt depending on model.

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.
