installation procedure
gas connection (nda1402)
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 are connection. All completed connections should be
checked for leaks with a non corrosive commercial bubble
solution.
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:
> 1/2 psi• - the refrigerator and its individual shutoff valve
must be disconnected from the gas supply piping system.
≤ • 1/2 psi - the appliance must be isolated from the gas
supply piping system by closing its individual manual shut-
off valve.
For detailed instructions on the installation and connection to
the gas supply, contact your dealer or distributor.
installing the drain water hose
To install the drain water hose, follow these steps:
Drill a hole through ooring. It is essential that it is 1.
drilled in the cut out opening of the base plate at the
rear of the refrigerator.
Make sure that the hose does not kink when run 2.
through the oor.
Seal around the hose that goes through the drilled 3.
hole. If a longer hose than supplied is required, the
installer needs to supply one in order for the water to
drain outside of the vehicle.
testing lp gas safety shut off
The gas safety shut off must be tested after the refrigerator is
connected to LP gas supply. To test the gas safety shut off, fol-
low these steps:
Turn on the refrigerator and switch to GAS mode.1.
Check that the GAS indicator dot is illuminated and 2.
the gas ame is lit.
Close the manual gas shut off valve at the back of 3.
the refrigerator.

electrical connection
120 v ac connection
The refrigerator is equipped with a three-prong (grounding)
plug for your protection against shock hazards and should be
plugged directly into a properly grounded three prong recep-
tacle. DO NOT cut or remove the grounding prong from this
plug!
The free length of the cord is 2 feet and it is recommended that
the receptacle is located to the right side of the refrigerator
(viewed from the rear).
The receptacle should be 3” (from
the bottom of the plastic receptacle)
above the refrigerator mounting oor.
This allows easy access through the
vent door. The cord should be routed
to avoid direct contact with com-
ponents that could damage the cord
insulation.

12 v dc connection
The refrigerator requires a continuous 12 V DC supply to main-
tain the automatic energy selector system and the auto defrost
control system to function.
The connection is made to the positive (+) and negative (-)
terminals of the terminal block on the back of the refrigerator.
Correct polarity must be observed when connecting to the DC
supply. Do not use the chassis or vehicle frame as one of the
conductors. Connect two wires at the refrigerator and route to
the DC supply.
Maximum fuse size for the DC supply is 10 A.
Wait for approx. 6-7 minutes. The message 4.
“ch LP” is displayed (ashing).
Remove the protection cover. 5.
Open the manual gas shut off valve. (Do not change 6.
any button positions on the control panel.)
Apply a non corrosive commercial bubble solution 7.
to the burner jet orice. No bubbles should appear at
the opening of the burner jet orice. The presence of
bubbles indicates a defective gas safety shut off, and
service is required.
If no bubbles were present at the burner jet orice, 8.
rinse it with fresh water. Be careful not to damage
the burner jet orice.
Put back the cover.9.
Switch the refrigerator OFF and back ON again. 10.
Normal operation of the burner should return.
Allow the burner to operate for a minimum of 5 11.
