FIG. 9
Install the two screws in the top frame, the holes are
accessible from beneath.
After the two screws have been installed, seal the holes
in the top frame with a piece of tape.
Replace the top decoration panel.
Make sure the tabs snap back into the holes in the hinge
plate.
Third: Two screws installed in the rear base.
See FIG. 10.
Hole for drain water hose
FIG. 10
Failure to follow the sequence in securing refrigerator in
enclosure can cause leakage between the frame and
cabinet. Any space between the counter, storage area
or ceiling and top of the refrigerator greater than 1-1/2
inches should be blocked. The heat produced at the rear
of the refrigerator will become trapped in this space,
making the top of the refrigerator hot and reduce the
efficiency of the refrigerator.
Drain water hose
A hole must be drilled through flooring see FIG. 10.
The hole must be drilled in the cut out opening of the
base plate at the rear of the refrigerator. The installer
MUST make sure that the hose does not kink when run
through the floor. Seal around the hose that goes
through the drilled hole. If a longer hose than supplied is
required to get the water to drain outside of the vehicle,
the installer will have to supply the extra length of hose.
GAS CONNECTION
Hook-up to the gas supply line is accomplished at the
manual gas valve, which is furnished with a 3/8" SAE
(UNF 5/8" -18) male flare connection. All completed
connections should be checked for leaks with soapy
water.

DO NOT use a flame to check for gas leaks.
The gas supply system must incorporate a pressure
regulator to maintain a supply pressure of not more than
11 inches water column.
When testing the gas supply system at test pressures in
excess of 1/2 psig, the refrigerator and its individual
shutoff valve must be disconnected from the gas supply
piping system.
When testing the gas supply system at pressures less
than or equal to 1/2 psig, the appliance must be isolated
from the gas supply piping system by closing its individual
manual shutoff valve.
In case detailed instructions on the installation and
connection to the gas supply are required, contact your
dealer or distributor.
TESTING LP GAS SAFETY
SHUTOFF
The gas safety shutoff must be tested after the re-
frigerator is connected to the LP gas supply.
To test the gas safety shutoff, proceed as follows:

WARNING
Start the refrigerator according to the instructions for
Gas Operation.
Check that the gas flame is lit. The red indicator D is
on the green field, (ON).
Close the manual gas shutoff valve by turning the
knob A back to "OFF" position.
Wait for one minute, then disconnect the 12 volt DC
power to the reigniter.
Remove protection cover (see FIG. 1) and open the
manual gas shutoff valve by turning knob A to the
"GAS" position without pushing button C. The reig-
niter should not be sparking. Apply a non-corrosive
commercial bubble solution to the burner jet. Be
careful not to damage the burner jet.
No bubbles should appear at the opening of the
burner jet. The presence of bubbles indicates a de-
fective gas safety shutoff and service is required.
If no bubbles were present at the burner jet, the gas
safety valve is working properly. Rinse jet thoroughly
with fresh water before proceeding. Be careful not to
damage the burner jet. Replace the protection cover.
Reconnect the 12 volt DC power supply to the reig-
niter. Start the refrigerator by following the instruction
for Gas Operation. Normal operation of the burner
should now return. Allow the burner to operate for a
minimum of five minutes.
