WARNING

FIRE HAZARD

When filling the tank, provide a metal-to-metal contact between fuel tank and container. This will prevent a spark

from being generated as fuel flows over the metallic surface. Do not fill fuel tank while I engine is in operation.

Gasoline spilled on a hot engine may explode and cause serious injury to personnel.

WARNING

DANGEROUS GASES

Do not operate or test-run the refrigeration unit in an enclosed area unless the exhaust gases are piped to the

outside. Exhaust gases contain carbon monoxide, a colorless, odorless, and poisonous gas. Refrigerant R-12

decomposes in the presence of flame. Therefore, quantities should not be released where a torch is being used

for welding, since the R-12 will decompose into phosgene gas, a lung irritant.

WARNING

Make sure refrigerant charge has been released into the refrigerant system before operating the unit. Disconnect

the power source from the refrigeration unit before performing maintenance on wiring or components. Failure to

observe this warning may result in injury to personnel and damage to the equipment. Do not use a lifting device

of less than 1500 pounds capacity. Do not allow unit to swing while suspended from lifting device. Failure to

observe this precaution may result in injury to personnel and damage to the equipment. Avoid bodily contact

with liquid refrigerant, and avoid inhaling of refrigerant gas. When working with or handling refrigerant, always

wear approved goggles to prevent possible eye injury. In case of refrigerant leaks, ventilate area at once; high

concentration of refrigerant can cause suffocation. Evacuate all gasoline fumes from the unit before soldering or

using Halide leak detector on refrigeration components. Do not apply heat to refrigerant cylinder containing

refrigerant with a Prestolite torch, blow torch, electric or gas stove, or any other heating device over which there

is no temperature control. To apply heat to a refrigerant cylinder, use a shallow vessel containing tap or

lukewarm water or apply cloths heated in hot water. Attach a pressure gage to the cylinder so the pressure is

always known. Always replace refrigerant cylinder valve cap after using the cylinder. Before breaking any

refrigerant connections, loosen slightly to be sure that liquid refrigerant is not present. Do not drop a refrigerant

cylinder or allow cylinder to strike another drum violently. Do not spill or allow oil to remain on floor; it may

cause personnel to fall or slip and come into contact with a rotating part. The burning of polyurethane foams is

dangerous. Due to the chemical composition of polyurethane foam, toxic fumes are released when it is burned or

heated. If it is burned or heated indoors, such as during a welding operation in its proximity, precautions should

be taken to adequately ventilate the area. An exhaust system equivalent to that of a paint spray booth should be

used. Air supplied respirators, approved by the National Institute for Occupational Safety & Health or the U. S.

Bureau of Mines, should be used for all welding in confined spaces and when ventilation is inadequate.

Individuals who have chronic or recurrent respiratory conditions, including allergies and asthma, should not be

employed in this type of environment.

WARNING

Liquid refrigerant is used in this equipment.

Severe injury may result if personnel fail to observe safety

precautions.

WARNING

Do not operate gasoline engine or refrigeration unit in an enclosed area unless exhaust gases are piped outside.

Inhalation of the gases could result in serious illness or death.

WARNING

Check engine fuel system for leaks or seeps and repair before soldering or using a Halide leak detector. Further,

seal the vent hole in the fuel tank cap with tape and cover with a wet cloth. Then ventilate unit to evacuate

gasoline fumes. Failure to follow this procedure could result in a flash or explosion, causing serious injury or

death to personnel.

WARNING

Dry cleaning solvent, Fed. Spec. P-D-680 or P-S-661, used to clean parts, is potentially dangerous to personnel

and property. Do not use near an open flame or excessive heat. The flash point of solvent is 1000F-138°F. (38°C.

to 59°C.)
