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

inthis instruction manualhave beencertifiedfor usewith

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.Thelower ventof the recommendedkitsis

provided with proper size openings.

The flow of ventilating air must not be obstructed.

Thelower sidevent isfitted witha panel,whichprovides

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

Therefrigerator isequipped witha three-prong(ground-

ing) plug for your protection against shock hazards and

shouldbepluggeddirectlyintoaproperlygroundedthree-

prongreceptacle. DONOTcut orremove thegrounding

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-

lectorsystemandthe autodefrostcontrolsystem 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).Correctpolaritymustbeobserved

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

DCsupply.

Itis importantthat thewires to the12-volt DCterminal 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 10AWG should be used.

INSTALLING REFRIGERATOR IN

ENCLOSURE

Securing the Refrigerator

After the refrigerator is put in place, the refrigerator is to

be secured in the enclosure with six screws (not in-

cluded). The screws have to be installed in the following

order:

STEP1: Two screws installedthroughthe front base,

which includes the lower front strip installation.

The refrigerator is provided with a lower front strip

(shippedasaloosepart).Thefront strip isto be attached

after the refrigerator is set into the cutout opening.

1. Install the lower front strip by sliding it under the

bottom hinge plates, as shown in FIG. 5.

The transport support at the rear of the refrigerator can

be removed if necessary for the installation of the refrig-

erator in the enclosure. (See figure above).

NOTE: DO NOT install the appliance directly on

carpeting. Carpeting must be removed or

protectedby a metalor wood panelbeneath

the appliance, which extends at least full

width and depth of the appliance.

Caution: Use care when installing the refrigerator. This

refrigeratoris equippedwith thelatest vacuuminsulated

panel technology. These insulating panels are located

ontheTop, Back,Bottom, Sidesand Doors ofthe refrig-

erator.

If the surface is punctured, loss of insulation will occur,

resulting in poor refrigerator performance.

NOTE: A wood strip must be in place across the upper

openingof theenclosure.The topframe ofthe refrigera-

tor will be anchored to the wood strip with screws, see

FIG. 10.

The refrigerator must be installed in a substantial enclo-

sure and must be level. When installing the refrigerator

in the enclosure, all areas within the recess in which the

refrigerator is installed must be sealed.

Make sure that 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 ap-

plied to the rear surface of the front frame for this pur-

pose, see FIG. 4.

NOTE: Be careful not to damage the sealing strip when

the refrigerator is put in place.

FIG. 4

2. Secure the refrigerator and the lower front strip with

two screws: One screw through each hinge. See

FIG 6.

FIG. 5

FIG. 6

Step 2: Two screws installed in the top frame.

Open the doors and fasten the refrigerator with two

screwsthrough theholes underneaththe topdecoration

panel. See FIG. 7.

STEP 3: Two screws installed in the rear base.

See FIG. 8.

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

andtopoftherefrigeratorgreaterden 1-1/2inchesshould

be blocked. The heat produced at the rear of the refrig-

eratorwill become trapped in thisspace,making the top

of the refrigerator hot and reduce the efficiency of the

refrigerator.

Drain water hose

Ahole must be drilled through flooring see FIG. 8.

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

throughthefloor.Sealaroundthe hose thatgoesthrough

thedrilled hole.Ifa longerhose than suppliedis required

to get the water to drain outside of the vehicle, the in-

staller will have to supply the extra length of hose.

OPERATING

INSTRUCTIONS

IMPORTANCE OF LEVELING A

REFRIGERATOR

In an absorption refrigerator system, ammonia is lique-

fied in the finned condenser coil at the top rear of the

refrigerator. The liquid ammonia then flows into the

evaporator (inside the freezer section) and is exposed

to a circulating flow of hydrogen gas, which causes the

ammonia to evaporate, creating a cold condition in the

freezer.

When starting this refrigerator for the very first time, the

cooling cycle may require up to four hours of running

time before the cooling unit is fully operational.

Thetubingin theevaporatorsectionisspecifically sloped

to provide a continuous movement of liquid ammonia,

flowing 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

sections of the evaporator tubing. This will slow the cir-

culation of hydrogen and ammonia gas, or in severe

cases, completely block it, resulting in a loss of cooling.

Any time the vehicle is parked for several hours with the

refrigerator operating, the vehicle should be leveled to

prevent this loss of cooling. The vehicle needs to be

leveled only so it is comfortable to live in (no noticeable

sloping of floor or walls).

When the vehicle is moving, the leveling is not critical,

as the rolling and pitching movement of the vehicle will

pass to either side of level, keeping the liquid ammonia

from accumulating in the evaporator tubing.

OPERATION

This refrigerator is equipped with an automatic defrost-

ing control system.

Thedefrost systemwill automaticallycarry out defrostin

frozen food and fresh food compartment once per 24

hours. To be able to control the performance of the de-

frost intervals the system is equipped with a built in real

time clock.

Theclock has tobe set tolocal time atthe veryfirst start

up of the refrigerator or when the 12-volt DC supply has

been disconnected for a longer period of time.

A message on the LED panel will alert when the clock

needs to be set.
