GAS, AC AND DC OPERATION
UNIVERSAL LP GAS OPERATION
Before starting the refrigerator, open the shuto valve of the
gas bottle (check that there is enough gas). Open any on-
board shuto valve.
1. Start the refrigerator by turning turn knob A to
position (GAS).
2. Turn the thermostat knob B to position 4.
3. Press and hold button C and push button D for the
piezo igniter several times to light the burner.
This can be observed on the ame indicator E.
When the ame is lit, the red indicator is in the
green eld. (ON).
4. After the gas is lit keep button C pressed for 10 s.
Release the button and check that the red indicator
is in the green eld, (ON).
Note! After changing an ULPG tank, or after a long shut o
period, the gas line is likely to be lled with air. You may
have to repeat the lighting procedure several times to purge
the air out of the gas lines.
230-240 V AC OPERATION
Before operating the refrigerator, check that the voltage
stated on the data plate is the same as the main voltage in use.
1. Check to be sure that the power cord is properly
connected to the power supply.
2. Turn the knob A to the position marked “AC” for
230-240 volt AC operation.
3. Turn the thermostat knob B to position 4.
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, eciently
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).
!WARNING
The sealed cooling system must not be opened.
It contains corroding chemicals under high pressure.
OPERATING INSTRUCTIONS
A. ON/OFF, Fuel selector switch
B. Thermostat knob, Gas/Electric
C. Flame failure safety valve push-button
D. Piezo igniter
E. Flame indicator
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.
