INSTALLATION
VENTILATION
The installation shall be made in such a manner as to
provide necessary air circulation over the cooling unit.
Openings for air supply shall have a minimum dimen-
sion of not less than 1/4 inch.
Proper installation requires one lower fresh air intake
and one upper exhaust vent. The ventilation kits shown
in this instruction manual have been certified for use with
the refrigerator models listed in the table. For “Certified
Vent System Kits” see page 18.
The ventilation kits must be installed and used without
modification. The lower vent of the recommended kits is
provided with proper size openings.
The flow of ventilating air must not be obstructed.
The lower side vent is fitted with a panel, which provides
an adequate access opening for ready serviceability of
the refrigerator. This should be centered on the back of
the refrigerator.
ELECTRICAL CONNECTION
120 Volts AC Connection
The refrigerator is equipped with a three-prong (ground-
ing) plug for your protection against shock hazards and
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 and therefore rec-
ommended that the receptacle be located to the right
side of the refrigerator (viewed from the rear). The re-
ceptacle should be 3” (from the bottom of the plastic
receptacle) above the refrigerator mounting floor. (see
FIG. 3). This allows easy access through the vent door.
The cord should be routed to avoid direct contact with
components that could damage the cord insulation.
12 Volts DC Connection
The refrigerator model NEA 1402 require a continuous
12 volt DC supply to maintain the automatic energy se-
lector system and the auto defrost control system to func-
tion.
The connection is made to the positive (+) and negative
(-) terminals of the terminal block on the back of the re-
frigerator. (See FIG. 1). 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.
It is important that the wires to the 12-volt DC terminal is
of proper wire size.
Recommended conductor wires size and total conduc-
tor wires length are found in the table below.
Example: If the distance between the refrigerator and
the 12V DC supply is 20 ft., the total wire length is 40 ft.
and a wire size of 10 AWG should be used.
