IMPORTANCE OF LEVELING A
REFRIGERATOR
In an absorption refrigerator system, ammonia is lique-
fied in the finned condenser coil at the top rear of the
refrigerator. The liquid ammonia then flows into the
evaporator (inside the freezer section) and is exposed
to a circulating flow of hydrogen gas, which causes the
ammonia to evaporate, creating a cold condition in the
freezer.
When starting this refrigerator for the very first time, the
cooling cycle may require up to four hours of running
time before the cooling unit is fully operational.
The tubing in the evaporator section is specifically sloped
to provide a continuous movement of liquid ammonia,
flowing 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
sections of the evaporator tubing. This will slow the cir-
culation of hydrogen and ammonia gas, or in severe
cases, completely block it, resulting in a loss of cooling.
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
prevent this loss of cooling.
The vehicle needs to be leveled only so it is comfortable
to live in (no noticeable sloping of floor or walls).
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.
OPERATION
Before starting the refrigerator, check that all the manual
gas valves are in the ON position. DO NOT forget the
manual shutoff valve on the rear of the refrigerator see
FIG. 1.
This refrigerator is equipped with a semi Automatic
Energy Selector (AMES) control system, which can be
set to automatically select either 120 volt AC or LP gas
operation (AUTO mode), or if desired LP gas only (GAS
mode). On 3-way model the control system can manu-
ally be set to DC operation (DC mode).
The refrigerator controls will work down to 9.6 volt DC.

INSTRUCTIONS FOR MOUNTING THE
DOOR PANEL
The refrigerator is normally delivered without door panel.
The lower decoration strip and parts bag are taped in-
side the door.
Before starting the mounting work, check that the panel
dimensions are in compliance with those given in the
Table and the instructions are read thoroughly.
We recommend to mount the panel on the door before
the refrigerator is installed in the enclosure.
When mounting the panel, proceed as follows:
• Slide the panel from the bottom of the door into the
grooves on the vertical edges of the door .
• Push the panel upwards, take the two plastic panel
stops from the parts bag and put them in the two
holes at the lower door frame.
• Put the decoration strip across the door and fasten
it with three screws from the parts bag.
Most LP gas appliances used in recreational ve-
hicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is pos-
sible that the gasoline fumes could enter this
type of appliance and ignite from the burner
flame, CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, when refueling, shut off all
LP gas appliances which are vented to the out-
side.
