Precautions
Congratulations on the purchase of your
National Luna LEGACY Portable Fridge / Freezer.
The National Luna range of portable fridges and freezers are high-performance,
high eciency refrigerators ideal for harsh conditions and applications that are
limited to battery power such as o-road vehicles, caravans and solar installations.
The versatility of each of the National Luna models allows the use of a wide range
of AC supply voltage (85V DC - 265V AC) as well as 12-volt or 24-volt battery power
(9.6V AC - 31.5V DC).
The use of a custom-designed digital thermostat and smart control circuitry
ensures temperature stability and low power consumption.
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.
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 specications. (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 o, the interior light will still function if the
unit is connected to a power source).
• Do not block or cover the ventilation holes. (During o-road
conditions items may become lodged around the cooling area).

Air Flow
Spacing 100-200mm
Air Flow
Allow a 100-200 mm gap around the refrigerator
compressor area for ventilation (Airow). The
higher the ambient temperature, the more
ventilation space is required for ecient
airow and cooling. (In the case of restricted
airow, the compressor will automatically shut
down - see page 21 for Trouble Shooting).
Do not block or cover the ventilation holes.
(During o-road conditions items may
become lodged around the cooling area).
Getting to know your portable Fridge

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 specied wiring
is used. (See wiring guidelines on page 8)
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 suitable cables to connect the
female socket to the vehicle’s battery.
(Cable thicknesses of 4mm2or greater
is recommended.)
Centre Pin (+)
• If you choose to change the male plug on the DC cable supplied for a dierent
type of plug, rst ensure that all power has been disconnected.
• Split and strip the wires as required for the new plug. Take care to ensure that the
correct polarity is used on the new plug and crimp the connections where possible.

Installation Guidelines
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.
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 path.

cables to Battery

National Luna LEGACY Fridge Manual 8
This Fridge can accept a DC voltage
ranging from 9.6V to 31.5V, 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.
(After a 1 minute delay)
Suggested Wiring Specications / 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. (minimum 4mm2)
Note: Two wires (positive & negative) must be connected from the battery to the Fridge / plug point.

• Voltage of a battery can be an indication of its “state-of-charge”.
• The voltage-capacity relationship is most accurate when the
fridge is not running and the battery temperature is at 25°C.
• By measuring the voltage, we can estimate the amount of
energy remaining in the battery.
• Changes in temperature, battery age and general battery health
can inuence this relationship and therefore result in inaccurate
capacity measurement.
• Normal battery operation takes place between 12.0 and 12.6 volts.
• Depending on the manufacturer’s specications a normal car’s
alternator charges between 13.7 and 14.2 volts.
• A battery should not be discharged below 11.8 volts as a general
rule. A “deep-discharged” battery should be recharged as soon as
possible to prevent permanent damage.
Low Voltage Battery Protection
The Electronic Control Unit will cut-out at the LOW / MEDIUM / HIGH selected setting.
Once the compressor has cut-out, it will not restart (cut-in) until the voltage rises.
The table below reects the set points.

When using the unit in a 24-volt application
do not select battery protection “LOW”
as this may completely drain the battery bank.

HIGH 11.3 12.5 24.6 26.0
Note: these values are measured at the
Electronic Compressor Driver input. It is
important to note that poor / thin wiring
and bad connections to the battery can
cause a large voltage drop. When this
occurs the Fridge switches o and will
re-start again on a repeat cycle “hunting”.
NOTE: When connecting the fridge for the rst time, it will look at the cut-in voltage.
• If the battery protection is set on “High” the initial cut in voltage will be 12.5.
• If the battery is not fully charged the Fridge will not start. Simply select “Low” to start.
• When selecting “Low” the Fridge will operate within a voltage supply of 9.6-31.5Vdc.
Battery Voltage vs Capacity

National Luna LEGACY Fridge Manual 10
The compressor is controlled by the digital thermostat. It has a unique Multi - Speed (2,000 - 3,500 rpm)
capability which makes it ideal for use in all mobile applications up to an angle of 35 degrees. It can
function efciently in extreme conditions where it is not uncommon to have ambient temperatures
above 40ºC.
To control temperature, the thermostat sensor must be placed in a position in order to take an accurate
temperature reading.
For practical purposes National Luna has elected to place this temperature sensor behind the metal
surface forming the interior compartment of the Fridge/Freezer. Thus the switching on and off of the
compressor will be controlled by the compartment surface area temperature.
The inner volume of the cooling bin (i.e. core/centre temperature) will take time to “pull down” to
equalise the compartment temperature. (In practice it is common that the set temperature will be within
3ºC of the core temperature).
Ambient temperatures surrounding the Fridge must also be taken into consideration. Very high
ambient temperatures will affect the running time of the fridge. (e.g. The Fridge will run longer to
maintain or reach the target temperature setting.)

Press and hold the button for 3 seconds
to turn the fridge ON or OFF.
If power to the refrigerator is interrupted, it will default
to ON automatically.
Note: When the fridge is switched off, the interior light will
still function if the unit is connected to a power source.
The refrigerator is equipped with a multi-level battery
protection circuit.
The user has the choice of three voltage levels at
which the compressor will shut down to protect against
excessive battery discharge. (See page 9)
To change the protection level, press and hold
the button until the preferred level is reached.
Selecting the “Low” cut-out setting can cause excessive discharge resulting in damage to the battery.
Note: When changing the protection level the compressor will stop and restart 1 minute later (compressor
start delay). When powered by an AC source, the battery protection level can be changed, but will only
affect operation when the DC source is used.

Selecting the “Turbo” mode will override the Smart Compressor
Speed Control function and the unit will run at maximum speed
For situations where maximum cooling power is
required, press and hold the “Turbo” button until the
indicator is illuminated.
This will bypass the automatic control and force
high speed operation.
This Fridge is tted with a Smart Compressor Speed Control function which will vary the speed of the
compressor in order to conserve power and optimise performance.
At the start of each cycle the Fridge will automatically run at low speed for 3 minutes to equalize gas
pressure in the system.
• Logic 1 (Setting the compartment temperature in a range of +20ºC to -11ºC).
The compressor will operate at 3 speeds: low 2,000 rpm, medium 2,750 rpm and high 3,500 rpm.
When the inner compartment temperature is warm, the Fridge will automatically run at full speed
to bring the inner compartment temperature down as fast as possible. It will then step down to medium
speed to reach the set temperature point where the fridge will then switch off. The temperature will then be
maintained at low speed.
This logic makes the Fridge operate and maintain the desired compartment temperature under all
ambient temperature conditions optimising performance and efciency.
Should the temperature of the fridge contents change, such as when fresh foodstuffs are added, the
compressor will automatically speed up to cool the new contents.
• Logic 2 (Setting the compartment temperature in a range of -12ºC to -30ºC).
When temperatures are set below -11ºC, the Smart Compressor Control will operate at high speed to
bring temperature down as fast as possible to the desired set point. Thereafter the temperature will be
maintained at medium speed.
Using the TURBO function may increase power consumption
On initial plug-in, the compressor will have a one minute time delay before starting.

Temperatures can be selected between
+20°C and -30°C in 1°C increments.
When powering up the fridge the rst time, the temperature inside the fridge will be reected on
the display. (NOTE: the previously set temperature will be in memory)
To select the new cooling temperature, press and hold the button until the display starts to
ash. (The previous set temperature will be displayed).
Press or to raise or lower the desired temperature. The thermostat will accept the
new setting and exit the setting mode 10 seconds after the last button was pressed. (It will now
remember the new set temperature).
The temperature display will reect the inner compartment temperature prior to the new setting.
Provided the new setting is colder, the compressor will then switch on and cool the fridge further
to the set point. (During this time the run indicator light will be displayed).

By reducing the fridge side insulation to 42mm thickness, National Luna offers a fridge/freezer
to meet the demand for maximum fridge capacity where space is limited.
The freezer compartment has a separate internal lid. This prevents cold air escaping from the
freezer when the main lid is opened, adding to the efciency & ensuring stable temperatures within.
Although the compartment temperatures can be independantly set, it is recommended for the
efcient functioning of the unit that the compartment with the thicker insulation (with internal
freezer lid) be set as the colder freezer compartment.

A special feature of the NL50 and NL52 is the ability
to change the direction in which the lid opens.
The most common conguration is the
front-opening direction (shown on the right).
If the application prevents the lid from opening fully or
the refrigerator is installed long ways into a vehicle, it may
be advantageous to use the side-opening conguration.
The Fridge is supplied in the front-opening conguration.
In order to change the lid direction, follow these steps :
1. Close the lid. Remove both front latches and
lid handles.
2. Re-t one of the latches and lid handles to the
alternative latch positions on the side of
the refrigerator. (Keep the spare parts safe)
3. Remove all three hinges from the rear of the
refrigerator. Also remove the hinge cover plates from
the alternative hinge locations.
4. Re-t two of the hinges on the side of the refrigerator.
5. Align the lid and ensure that it closes fully before
tightening the screws.
6. Keep the spare hinge and screws in a safe place.
The Fridge will now be in the side-opening conguration
NOTE: Take care not to apply excessive pressure when
locating the screws to the inside retaining nuts.
(They can be pushed too far back or incorrectly
angled).
Tip - The optional protection jacket has a side pocket
which is ideal for keeping the spare hinge and latch
parts.

1Low voltage. This is shown when the DC supply voltage is low. The battery could be
at, wiring losses are too high or there is a poor connection to the power source.
2Fan over-current cut-out. There is a problem with the ventilation fan. It is possible that
the ventilation fan is damaged.
3Motor start error. The compressor has not started successfully. This can happen in
extreme environments where the refrigerator is heavily loaded & temperature is very high.
4Minimum speed error. The motor cannot maintain a minimum speed of 1900 rpm.
This can be the result of an Electronic Compressor Driver failure.
5Thermal cut-out. The electronic circuitry has over-heated. This happens in very hot
environments. This can occur when the fridge is over-loaded with warm contents and
the ambient temperature is high. The electronics will re-set when the temperature
has dropped.
