consume propane, 120-volt AC, and 12-volt DC power.
To keep units at cool temperatures, it MUST remove the heat from box,
keeping the temperature down to 34 to 38 degrees, to protect your food.
Types of cooling units:
1. Absorption system requires precise leveling within 1 degree. Air
MUST enter at lower service vent, be allowed to escape at upper
vent, and unrestricted.
2. A 12-volt DC compressor being supplied with 120-volt AC,
feeding the converter to produce 12-volt DC power to cool box.
Leveling is not as important as the absorption system.
A "house" type is used as a free standing unit in several large

CANNOT keep food cold while traveling. All refrigerators used
in outside kitchens are 120-volt AC only.
Performance of refrigerators depends on various factors, such as, power,
venting, leveling, humidity and atmospheric heat temperatures, but not
limited to these.

Leveling

For correct operation, the refrigerator must be within three degrees of
level in any direction. Operating it at more than these limits can cause
damage to the cooling system and create a risk of personal injury or
property damage. The closer to level, the better it performs.

Venting

For an absorption unit to operate fully it MUST have two vents. The lower
vent serves as access to service components and allows air to enter. As
the refrigerator heats up, warm air leaves through the upper vent in the
roof or the upper side vent. The roof vent gives the best "chimney"
results. However with correct baffles, side vent is efficient. All vents
MUST prevent birds and rodents from entering.
Units with two side vents, as in a slideout, require a 12-volt fan to be in
operation. When upper cooling fins reach 150 degrees Fahrenheit, the
fan will automatically start to operate. The positive wire has a 5 amp in-
line fuse installed. Access to the fuse is inside the lower vent door and
upward, between walls and coils.

Moisture Reduction Heater

The refrigerator has a heater that prevents moisture from forming on the
center divider between the doors of the freezer and the fresh food
compartment. The heater operates only when the refrigerator is on.

Door Sealing

Check the seal of the doors. If either door does not seal correctly, excess
