CERTIFICATION AND CODE REQUIREMENTS
REFRIGERATOR OVERVIEW
ABSORPTION COOLING SYSTEM
In an absorption refrigerator system, ammonia is liquefi ed in
the fi nned condenser coil at the top rear of the refrigerator.
The liquid ammonia then fl ows into the evaporator (inside the
freezer section) and is exposed to a circulating fl ow of hydro-
gen gas, which causes the ammonia to evaporate, creating a
cold condition in the freezer.
When starting this refrigerator for the very fi rst time,
the cooling cycle may require up to four hours of run-
ning time before the cooling unit is fully operational.
The tubing in the evaporator section is specifi cally sloped to
provide a continuous movement of liquid ammonia, fl owing
downward by gravity through this section.
Sodium chromate is used for corrosion protection (less than
2 weight % of the coolant).
Leveling the refrigerator
Leveling is one of the requirements for proper operation with
absorption refrigerators. to ensure proper leveling the vehicle
needs to be leveled only so it is comfortable to live in (no no-
ticeable sloping of fl oor or walls).
Any time the vehicle is parked for several hours with the refrig-
erator operating, the vehicle should be leveled to prevent this
loss of cooling.
If the refrigerator is operated when it is not level and the
vehicle 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.
When the vehicle is moving, the leveling is not critical, as the
rolling and pitching movement of the vehicle will pass to either
side of level, keeping the liquid ammonia from accumulating in
the evaporator tubing.
AUTOMATIC ENERGY SELECTOR SYSTEM
The refrigerator is equipped with an automatic energy selector
system. The user turns the refrigerator on and then, the refriger-
ator automatically selects the most suitable energy source avail-
able, either 120 V AC or LP gas operation. The system can be
set by the user to be fully automatic (AUTO mode is selected)
or to operate on LP gas only (AUTO mode is off).
On 3-way models, the control system can manually be set to
DC mode (DC operation). The DC mode overrides all other
operating modes.
The refrigerator controls will work down to 9.6 V DC.
When parked close to a gasoline pump, it is
possible that gasoline fumes could enter LP gas
appliances vented to the outside of the vehicle.
These can ignite from the burner fl ame and cause a
fi re or an explosion!
For your safety, when refueling, shut off all LP gas
appliances vented to the outside of the vehicle!
