Venting
For an absorption unit to operate fully, it MUST have two vents. The lower
vent serves as access to service the components and allows air to enter.
As the refrigerator cooling unit 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 vents are efficient.
All vents MUST have screens to prevent birds and rodents from entering.
Units with two side vents, such as in a slideout, requires a 12-Volt fan to
be in operation. When upper cooling fins reach 150°, the fan will
automatically start. The positive wire has a 5 amp in-line fuse installed.
Access to the fuse is inside the lower vent door and upward, between the
wall and coils.
These absorption systems come in numerous sizes, from 2.3cuft to
10cuft. Performance of these refrigerators depends on various factors,
such as; energy, venting, leveling, humidity, and atmospheric heat
temperatures, but limited to these.
Door Seal
To maintain cooling efficiency the door must seal completely on all four
sides along the door gaskets. Frequent frost build up or reduced cooling
are indicators of air leaks around the doors. Place a strip of paper the size
of a dollar bill between the flange and door gasket. Close the door and
pull the paper out. There should be a light frictional drag indicating proper
seal. Should the paper feel loose, the gasket is not sealing well. Contact
your dealer or service center.
Door Latch
A positive or full locking latch is not permitted through codes. Each latch
has a rating by pounds of pressure, yet will prevent the door from opening
during travel.
Operating Instructions
In order for proper operation, and to achieve proper cooling, 12-Volt DC
power MUST be present at the power supply board. Power comes from
the solid state converter, auxiliary or tow vehicle battery.
For smaller 3 and 4 cubic foot units follow the directions given in Norcold
owner’s manual as supplied by manufacture.
Do not use undue force or jerking action when opening the
refrigerator door. Air temperature differences can cause a
partial vacuum within the cabinet requiring a firm, but steady
force to open. A sudden jerk could cause door damage or
personal damage.
