Safety Precautions

Read this manual and become thoroughly acquainted with it before installing or starting the refrigerator. The following safety precautions and recommendations contained herein are for your protection.

Improper installation, adjustment, or operation can cause injury or property damage.

The safety symbols used in this manual contain Safety Alert information. Understand their meanings and be safety conscious.

DANGER

WARNING

CAUTION

General

A SITUATION WHICH, IF NOT AVOIDED, WILL RESULT IN DEATH OR SERIOUS INJURY.

A SITUATION WHICH, IF NOT AVOIDED, COULD RESULT IN DEATH OR SERIOUS INJURY.

A SITUATION WHICH, IF NOT AVOIDED, MAY RESULT IN MINOR OR MODERATE INJURY.

∙Keep the unit and surrounding area clean. Never use the area behind refrigerator for storage; in particular, storing flammable materials (oily rags, paper, aerosol cans, and chemicals.). Stored materials not only present a safety hazard but could block the ventilation to the system.

∙Provide appropriate fire extinguishers installed in convenient locations. Consult your local fire department for the correct type to use. Do not use foam on electrical fires. Use extinguisher rated by NFPA.

∙Make sure all fasteners, supports, seals, electrical covers are secure.

LP Gas System

∙LP gas is highly flammable. Gas connections must be leak tight. Do not smoke, create sparks or use an open flame when checking gas connections. Do not ignore the "rotten egg" smell of gas fumes.

∙Protect all gas lines from physical damage, vibration, or excessive heat.

∙Insure that the supply gas pressure is within the tolerance specified on the front cover of this manual. The gas controls are designed for safety. Never tamper with the adjustment or function of the controls other than as directed by the Lighting and Shutdown Instructions. All repairs must be done by a qualified service person.

Exhaust Gases

∙Proper ventilation to remove exhaust gases is extremely important. These gases, generated in the GAS mode at the rear of the refrigerator, replace the oxygen in the air and in extreme cases can produce dangerous levels of carbon monoxide. This manual contains installation instructions to safely remove the exhaust gases and seal the zone from the living area. The installation instructions are certified by American Gas Association and Canadian Gas Association and must be followed.

∙Check the burner for proper flame characteristics at the initial start-up and at least once every year. The information for this check is located in this manual and must be performed by a qualified service person.

Safety Precautions - continued

Electrical Circuits - AC and DC

∙The 120 volt AC circuit must be properly grounded. Never cut or remove the round grounding prong from the refrigerator’s AC cord. Do not use a two-prong adapter. Do not use an extension cord to connect to the approved AC receptacle.

∙Protect all wiring from physical damage, vibration, or excessive heat.

∙Always disconnect both AC and DC sources of power when working on either circuit (only a qualified service person).

∙Insure all terminating connections are clean and tight to prevent arcing or overheating.

∙Never allow Leak Detecting fluids or any other liquids to spill on electrical connections. Many liquids are electrically conductive and could cause serious arcing damage and, in some case, fires.

Refrigerant System

∙Never physically bend, drop, drill, weld, or hammer the refrigerant system. Doing so could cause the system to rupture and release dangerous chemicals which can cause severe burns to the eyes or skin. If ignited, these chemicals will burn with intense flame. A leaking system can release certain chromium components which, if inhaled, can cause cancer.

∙Never apply direct heat in excess of 240° F to the refrigerant system. Because the refrigerant is hermetically sealed under pressure, a temperature sensitive safety device opens to protect the system from erupting under excessive pressure. However, the expelled refrigerant could ignite and burn if an ignition source were near.

∙Never attempt to repair or recharge the refrigerant system. If defective, it must be replaced.

Child Entrapment

∙Never install door locks or other restraints which could entrap small children within the refrigerator. The Travel Latch system must not be modified.

Handling the Refrigerator

∙Never lift the refrigerator without assistance. Protect yourself from body strain.

∙Avoid hot surfaces at the rear of the refrigerator when operating. The absorption type refrigerator produces several hot areas at the rear of the unit. This is true whether in GAS or ELECTRIC mode.

∙Take care to avoid brushing against the irregular shapes and sheet metal parts at the rear of the refrigerator. Cuts or abrasions could result.

General Instructions - All Models

The refrigerators described in this manual are designed for built-in installations and require cut out dimensions as indicated on page .

The refrigerators must be placed on a solid and level floor away from heat generating sources. The floor must be strong enough to support the combined weight of the refrigerator and its food load.

Never install the refrigerator directly on carpeting. To protect carpeting, the refrigerator must be placed on a metal or wood panel extending at least the full width and depth of the refrigerator.

Keep the refrigerator and the surrounding area clear and free of combustible materials, gasoline, and other flammable materials.

Note: These appliances are not approved for use as a Free-Standing refrigerator. The refrigerator must be used in the manner for which it was designed. Refer to this manual for installation, operating procedures, and the refrigerator intended use. This appliance is equipped for LP gas and cannot be converted to any other fuels (Natural Gas, Butane, etc.).

VENTILATION REQUIREMENTS

WARNING: Carbon Monoxide can cause nausea, fainting, or death. Inadequate ventilation or partial blockage of the refrigerator’s flue can result in increased carbon monoxide emissions when operating in the gas mode. To prevent the emission of levels of carbon monoxide, installation must assure complete isolation of the living space of the R.V. from the refrigerator’s combustion system. Follow Norcold’s Ventilation and Installation recommendations explicity.

Venting is required in an R.V. refrigerator installation to remove the products of combustion, to isolate the living space of the vehicle from the combustion system of the refrigerator, to remove the excess heat from the generator area of the refrigerator’s cooling system, and to remove the heat that is extracted from the refrigerator cabinet.

Certified installation requires that one intake (lower) and one exhaust (upper) be used. For the models 6052, 6053, 652, and 653, the installer has the option of exhausting through the roof or through an upper side wall vent. Whether roof or side wall exhaust venting, the specified vent kit must be installed as directed by this manual. To insure adequate refrigerator performance, a continuous air flow is required across the refrigerator’s cooling system.

The air passage from the intake vent to the refrigerator coils and from the refrigerator coils through the exhaust vent must be unobstructed.

TABLE 1

DIMENSIONS (INCHES) for Vent Kits 2, 3, and 4

The vents for these refrigerators are certified by A.G.A. and CGA and must be installed as directed by this manual without modification. Any deviation or substitution:

*Can result in carbon monoxide levels in the living space of the vehicle.

*Will void the agencies’ certification.

*Will void the refrigerator warranty.

*Will effect refrigerator performance.

The intake vent (lower) also serves as a access (service entrance) door. The bottom of the intake vent opening must be flush with the surface on which the refrigerator is mounted. This configuration allows any leaking propane to ventilate to the outside.

A.G.A. And CGA certification permits installing the refrigerator with zero (0) inches minimum clearance between the refrigerator and any adjacent walls. This certification does not specify any maximum clearance. However, to insure adequate air flow across the cooling system, the clearance must be minimized. The combination of the two vents and the minimum clearances provide the necessary air flow through the creation of a natural draft, or "chimney effect" across the cooling system.
