INSTALLATION INSTRUCTIONS
INSTALLING THE REFRIGERATOR
SECURING THE REFRIGERATOR
Be careful when installing the refrigerator model
NDR1062. It is equipped with the latest vacuum
insulated panel technology. These insulating panels
are located on the top, back, bottom, sides and doors.
If the surface is punctured, loss of insulation will occur, resulting in poor refrigerator performance.
For a proper installation, follow these instructions:
• Make sure the floor is solid and level.
• The refrigerator must be level and installed in a substantial
enclosure.
When installing the refrigerator, make sure the heat can not be
trapped in the space between the refrigerator and storage area.
This would make the top of the refrigerator hot and reduces the
efficiency of the refrigerator. Any space between the counter,
storage area or ceiling and top of the refrigerator greater than
1½ inches should be blocked.
After the refrigerator has been installed (ensuring a combustion
seal at the front frame) it must be secured in the enclosure with
screws (not included). Note that it is important to follow the
sequence in securing refrigerator since failure in doing that can
cause leakage between the frame and cabinet!
RM2351-2354
• Do not install the appliance directly on carpeting. Carpeting must be removed or protected by a metal or wood panel
beneath the appliance, which extends at least full width and
depth of the appliance.
Install the five screws in the following order:
1. Four screws installed through the front frame.
(To cover the screw heads, use the plugs in the parts
bag.)
2. One screw installed in the rear base.
• RM2451-2454-2551-2554-2652-2662-2663-2852-28623862 & NDR1062
A wood strip must be in place across the
upper opening of the enclosure. The top
frame of the refrigerator will be anchored to
����������
the wood strip with screws.
• All areas within the recess have to be sealed. The sealing
should provide a provide a complete isolation of the appliance’s combustion system from the vehicle interior.
Make sure there is a complete seal between the front frame
of the refrigerator and the top, sides and bottom of the enclosure. A length of sealing strip is applied to the rear surface of
the front frame for this purpose.
RM2351 and RM2354: In addition, apply a sealing strip to
the foremost floor of the enclosure.

Be careful not to damage the sealing strip when the
refrigerator is put in place!
RM2451-2454-2551-2554-2652-2662-2663-28522862-3862 & NDR1062
Install the six screws in the following order:
1. Two screws installed through the front base.
(Installation of the lower front strip.)
a) The refrigerator is provided with a lower front
strip (shipped as a loose part). The front strip is
to be attached after the
refrigerator is set into
the cutout opening.
RM2451-2454-2551-25542652-2662-2663-28522862-3862 &NDR1062
Install the lower front
strip by sliding it
under the bottom
hinge plate.
The hinge plate can be
on the right or left side
depending on the door swing.
Once the lower front strip is slipped under the
hinge, the part is possible to swing into place.

INSTALLATION INSTRUCTIONS
b) Secure the refrigerator and the lower front strip
with two screws: One screw through the hinge
and on the opposite side and then, one screw
through the lower front strip.
DRAIN WATER HOSE
A hole must be drilled through flooring and the installer needs
to make sure 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.
RM2451-2454-2551-25542652-2662-2663-28522862-3862 & NDR1062
2. Two screws installed in the top frame.

CONNECTIONS
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 examined for leaks using a solution of liquid detergent and water.
! WARNING
Be very careful when working on or near the gas system. Do not use an open 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:
• > 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 shutoff valve.
If detailed instructions on the installation and connection to
the gas supply are required, please contact your dealer or
distributor.

The refrigerator is equipped with a grounded three-prong plug
for protection against shock hazards. It should be plugged directly into a properly grounded three-prong receptacle. Do not
cut or remove the grounding prong from this plug!
The free length of the cord is 2 feet. It should be routed to
avoid direct contact with the burner cover, flue cover or any
other components that could damage the cord insulation.
To allow easy access through the vent door, it is recommended
that the receptacle is placed:
• To the left of the refrigerator. (On the opposite side of the
refrigerator burner assembly.)
• 3” above the refrigerator mounting floor

INSTALLATION INSTRUCTIONS
12 V DC connection
RM2451-2551-2652-2852: These refrigerator models are not
designed for 12 V DC operation of the cooling system. However, 12 V DC must be supplied to operate the controls.
RM2354-2454-2554-2662-2663-2862-3862 & NDR1062:
These refrigerator models require a continuous 12 V DC supply to maintain the automatic energy system.
For 3-way models, the voltage drop affects the wattage output
of the 12V cartridge heater and the refrigerator performance.
The 12V DC heater is fused with a 30 amp. in-line blade fuse.
Recommended wire sizes are displayed in the following table:
CONDUCTOR WIRE SIZE AND LENGTH
WIRE
Size
Length
The connection is made to the positive (+) and negative (-)
terminals of the terminal block on back of the refrigerator, see
APPENDIX A - REARVIEW EQUIPMENT. 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. Ensure the
connections are clean, tight and free from corrosion.
The distance the current must travel from the battery to the
refrigerator dictates the AWG wire size to be used. Should the
wire be too small for the distance, a voltage drop will result
causing a decreased cooling capacity.
