ABSORPTION REFRIGERATOR SYSTEM
In an absorption refrigerator system, ammonia is liqueed in
the nned condenser coil at the top rear of the refrigerator.
The liquid ammonia then ows into the evaporator (inside the
freezer section) and is exposed to a circulating ow of hydro-
gen gas, which causes the ammonia to evaporate, creating a
cold condition in the freezer.
The tubing in the evaporator section is specically sloped to
provide a continuous movement of liquid ammonia, owing
downward by gravity through this section.
If the refrigerator is operated when it is not level and the ve-
hicle is not moving, liquid ammonia will accumulate in sec-
tions of the evaporator tubing. This will slow the circulation
of hydrogen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.
Note! Any time the vehicle is parked for several hours with
the refrigerator operating, the vehicle must be levelled to
prevent this loss of cooling.
When the vehicle is moving, the levelling is not critical, as
the rolling and pitching movement of the vehicle will pass
to either side of level, keeping the liquid ammonia from ac-
cumulating in the evaporator tubing.

GENERAL ADVICE AND INFORMATION
Make sure defrosting is carried out periodically
The refrigerator should be kept clean and dry with the
door left open when it is not to be used for some time.
Ensure that liquids or items with a strong odour are well
packaged.
Service and maintenance must be done on a regular sched-
ule to keep the refrigerator operating properly, efciently
and safely. The service should be performed by qualied
personnel only.
Avoid spraying water through the refrigerator vents while
washing your RV.
Sodium chromate is used for corrosion protection (less than
2 weight % of the coolant).
