Leveling Absorption Type
For correct operation, the refrigerator MUST be within three degrees of
level in any direction. At 1 degree out of level, it will have one end of a 30
foot trailer 5 inches higher than the other end. Continued operation
outside of these limits will result in irreparable damage to the cooling unit
in the refrigerator.
Venting Absorption Type
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 side vent. The roof vent gives the best “chimney” results. With
correct baffles, side vent will work. All vents MUST prevent birds and
rodents from entering.
Units with 2 side vents in a slideout, require a 12V fan to be in
operation. When upper cooling fins reach 150° 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 of the lower service vent
door.
2. A 12-volt Compressor being supplied with 120-volt, feeding the
converter to produce 12-volt provides energy to cool the appliance.
Leveling and venting is less critical for the absorption system. See
owner’s manual supplied by manufacturer for more instructions.
KZRV is now using 12-volt DC compressor powered refrigerators. Power
of 12-volt DC will be supplied by converter on regular basis. Provisions
must be allowed for a small quantity of air to circulate. Air enters in at the
bottom and out the top.
A dedicated 8 gauge wire is required to provide power for compressor to
operate. A 15 amp breaker is placed in distribution sections of converter
for protection and operation.
In the installation instructions, there are 18 warnings and cautions plus
more in the operator’s manual. Read and obey as several fall in the
“DANGER” category.
Always pre-cool the refrigerator for 8 hours or more before placing food
into it.
Read the operator’s manual to be aware of all the areas to turn on, start,
stop, achieve the desired temperature for coolness, etc. Many helpful
hints and ideas are listed for you.

A free standing “house” type unit is used in larger travel trailers, which
uses 120-volt AC only.
The last 2 CANNOT keep food cold while traveling, unless special
