introduction
refrigerator overview
Thank you for entrusting us to supply your new quality-guaranteed refrigerator which is to be used as a recreational device
designed for storage of foods, frozen foods and making ice. Please, when the refrigerator is not in use as a recreational device,
turn the system off and open the door(s).
This manual describes how to operate NEA1402 (all-electric) and NDA1402 (2-way operated). Read it carefully to ensure that
you know how to operate the refrigerator safely and correctly. Be aware of possible safety hazards when seeing alert symbols on
the refrigerator as well as in this manual. The manual should be kept and stay with the refrigerator if it is ever moved or change
owners.
Servicing should be performed by qualified personnel only! Thus, the section regarding maintenance and service is intended for
service personnel. For installation instructions, refer to the
INSTAllATIoN mANUAl.
features
This side-by-side refrigerator-freezer has two compartments
•
with separate doors. The left one is a frozen food compart-
ment (the freezer) and the right one is a fresh food com-
partment (the fridge). Both compartments have automatic
defrosting and independent temperature controls.
NDA1402
•
: 2-way power option. The cooling system may
use either 120V AC or lP gas as energy source for the cool-
ing. Energy selection is made either automatically or manu-
ally (forced to gas).
NEA1402
: All-electric operation.
models equipped with ice dispenser or both ice and water
•
dispenser: In order to make serving water and ice easier,
the refrigerator is equipped with a dispenser for ice cubes
and chilled water through the door. Without having to open
the freezer it provides water as well as crushed or cubed ice
right into the cup.
Climate control cooling system.
•
Digital controls show current temps in both compartments.
•
Vacuum insulated panels increase interior storage space.
•
Automatic front frame heater prevents condensation from
•
forming on exterior cabinet.
Flexible storage options.

absorption cooling system
In an absorption refrigerator system, ammonia is liquefied 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 hydro
-
gen 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 run
-
ning time before the cooling unit is fully operational.
The tubing in the evaporator section is specifically sloped to
provide a continuous movement of liquid ammonia, flowing
downward by gravity through this section.
leveling the refrigerator
leveling is one of the requirements for proper operation with
absorption refrigerators. To ensure proper leveling the vehicle
needs to be leveled so it is comfortable to live in (no noticeable
sloping of floor or walls).
Any time the vehicle is parked for several hours with the refrig-
erator operating, the vehicle should be leveled to prevent this
loss of cooling.
If the refrigerator is operated when it is not level and the
vehicle is not moving, liquid ammonia will accumulate in sec-
tions of the evaporator tubing. This will slow the circulation
of hydrogen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.
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.
CAUTION
Do not park your RV on a slope for a longer period of
time. Absorption refrigerators use a gravity-flow system.
Being on an angle of more than a couple of degrees for ex
-
tended periods of time stops the refrigeration and might
cause damage to the cooling unit.
