Getting to know your portable FridgeIntroduction
In 2018 Outdoor Warehouse commissioned National Luna to manufacture a unique
Stainless Steel chest-type refrigerator/freezer exclusively for their customers.
Developed for performance at high ambient temperatures, minimum power
consumption and high operating efciency, these single compartment Fridges are
recognised as the most powerful in the world.
Utilizing world-class technology, all refrigerator models are built using high quality
materials, unique assembly techniques and strict testing procedures to ensure the
highest level of quality and performance.
The use of a custom-designed digital thermostat and smart control circuitry ensures
temperature stability. Low power consumption is achieved using 42mm high-density
insulation and a very compact design.
National Luna is a South African company and was established in 1987.
In 1989 the company expanded into manufacturing high efciency chest-type
refrigeration for the solar power medical vaccine industry.
The National Luna range of portable Fridges and Freezers are high-performance,
high efciency refrigerators ideal for extreme conditions and applications that
operate off battery power, such as off-road vehicles, caravans and solar installations.
With the aid of an integrated electronic thermostat this unit can be accurately set
as a Fridge or as a Freezer (+20°C to -30°C).

Precautions
When the refrigerator is used in an automotive application, ensure that it is secured
to prevent accidental movement. The carry handles can be used with straps or
tie-downs if necessary.
• A base mounting plate is optional and recommended for most applications.
• Ensure the correct type of cable and connectors are used for installation.
• Ensure that any power leads connected to the refrigerator will not be pulled or
damaged by any movement of the Fridge - especially where slides or drawers are
used.
• Do not use a power lead that is damaged.
• Do not connect the refrigerator to a power source that does not comply with the
input power specications. (Displayed on the Fridge’s rear panel)
• When storing the Fridge, ensure that the lid is propped open to allow for breathing.
Disconnect the appliance from an electrical source. (Note: When the Fridge is
switched off, the interior light will still function if the unit is connected to a power
source).
Spacing 100-200mm
Air Flow
• Allow a 100-200 mm gap around the refrigerator compressor area for ventilation
(Airow). The higher the ambient temperature, the more ventilation space is
required for efcient airow and cooling. (In the case of inefcient airow and
cooling, the compressor will automatically shut down - see page 15 for
Trouble Shooting).
• Do not block or cover the ventilation holes. (During off-road conditions items may
become lodged around the cooling area).

A low-prole design with locking pin, this base offers a xed mounting position
with an easy to remove mechanism. The optional base mounting plate allows the
refrigerator to be securely fastened to the oor or body of the vehicle.
The unique locking design ensures that the Fridge remains xed in position.

Sturdy and functional carry handle.
A hold down strap can be tted in the
slot provided as indicated.
(Care must be taken not to
over-tighten the hold-down strap
when using a ratchet device.)

Electrical Connections
When installing the refrigerator into a vehicle for the rst time, ensure that the
electrical connections to the vehicle’s battery are secure and the specied wiring
is used. (See wiring guidelines on page 9)
The fridge is supplied with a power lead for use with a 12 Volt DC supply.
This power lead is terminated with a high-quality male plug for connection into
your vehicle.
1. Install the supplied female
socket into your vehicle
in a convenient location.
2. Use a suitable cable to connect the
socket to the vehicle’s battery.
A cable thickness of 4mm2or greater
is recommended.

Fitting an in-line fuse
Although the fridge has a built-in fuse, it
is recommended to install an additional
fuse on the positive wire as close to
the battery as possible. This will protect
against short-circuits that may occur
along the length of the cable.
Ensure that all connections are
properly crimped and insulated.
If you choose to change the attached plug on the DC cable for a different type,
rst ensure that the power has been disconnected before cutting it.
Split and strip the wires as required for the new plug. Take care to ensure that the
correct polarity is used on the plug and crimp the connections where possible.
An automotive fuse with a rating
of 15A is recommended
When installing electrical outlets in your vehicle, do
not rely on the vehicle’s body for an electrical earth.
Male Plug
Female Socket
This Fridge can accept a DC voltage
ranging from 9.6V to 17V, as well as an
AC voltage range from 85V to 265V.
The 12Vdc power input is protected
with a 15A automotive blade fuse.
An AC and DC source can be connected
to the refrigerator simultaneously. Under
these conditions, the AC supply will be
chosen as the primary power source.
If the AC supply is interrupted, the DC
supply will be automatically selected
and operation will continue normally.

Suggested Wiring Specications / Guidelines
One of the most problematic issues with installing a 12 Volt refrigeration system
is incorrect wiring. Most users do not understand the importance of maintaining
battery voltage over the distance from the battery to the installed Fridge.
While most car cigarette lighter sockets appear to be adequate, in practise a
large voltage drop occurs between the socket and the car battery. This may
result in the fridge shutting down as a result of a low-voltage condition.
It is recommended the following table be used as a guide to establish what cable
thickness is to be used depending on the distance from the car battery to the
fridge. As a rule of thumb one should use a 1.0 mm2multi-strand copper wire
per meter of distance from the battery.
Note: Two wires (positive & negative) must be connected from the battery to the Fridge / plug point.
