Page 4: Introduction
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). -
Page 5: Installation Guidelines
Installation guidelines When installing the refrigerator into a vehicle for the first time, ensure that the electrical connections to the vehicle’s battery are secure and the specified wiring is used. (See wiring guidelines on page 6) The fridge is supplied with a pre-made cable for use with a 12 / 24-volt DC supply. This cable is terminated with a high-quality male plug for connection into your vehicle. -
Page 6: Connecting Power
Connecting power All National Luna Portable refrigerators can accept a DC voltage ranging from 9.6V to 31.5V, as well as Fuse (15amp) an AC voltage range from 85V to 265V. Both power inputs are fuse protected : - 3.15A Time-lag fuse for AC input. -
Page 7: Temperature Settings
To control temperature, the thermostat sensor must be placed in a position in order to take a tempera- ture reading. For practical purposes National Luna has elected to place this temperature sensor on the metal surface forming the interior bin of the fridge/freezer. Thus the switching on and off of the compressor will be controlled by the bin surface area temperature. -

Setting the Temperature The digital thermostat fitted to the National Luna Portable refrigerator allows accurate setting of the desired cooling temperatures. With the single compartment refrigerators, temperatures can be selected between +20°C and -30°C in 1°C increments. When powering up the fridge the first time, the temperature inside the fridge will be reflected on the display. -
Page 9: Speed Control
Introduction to Smart Compressor Control National Luna developed a Smart Compressor Control ( advanced automatic speed control) function which has been fitted as standard to all current models. • Logic 1 (Setting the bin temperature in a range of +20ºC to -11ºC). -
Page 10: Battery Protection
Battery Voltage vs Capacity • 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. -
Page 11: Indicator Lights
Battery Protection Settings 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 10) To change the protection level, press and hold button until the preferred level is reached. -

Page 15: National Luna Double Door And Twin Range
Introduction The Double door and Twin fridges in this range have only one compressor but due to National Luna’s unique Dual Control technology, the fridge and freezer compartments can be set independently. This is like having two fridges in one. - Page 16 90 Litre Twin The Twin has one lid covering both compartments. 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 efficiency and ensuring stable temperatures within. 1.

Page 19: National Luna Weekender Range
The National Luna Weekender is a high-performance, low-power portable refrigerator designed primarily for use in mobile applications. By reducing the insulation to 42mm thickness, National Luna offers a lightweight fridge/freezer to meet the demand for maximum fridge capacity where space is a problem. -

- Page 24 Battery Monitor and Protection The Weekender is equipped with a battery monitor and low-battery “cut-out” protection circuit. The monitor is intended to give an estimate of the available remaining energy in a 12-volt lead-acid battery. (For 24V systems the indicated battery voltage should be multiplied by two). The battery monitor has a built-in low voltage alarm which provides audible warning of a low-battery condition.

Page 25: Dual-Direction Lid
Dual-direction Lid A special feature of the Weekender is the ability to change the direction in which the lid opens. The most common configuration is the front-opening direction (shown). If the application prevents the lid from opening fully or the refrigerator is installed long ways into a vehicle, is may be advantageous to use the side-opening configuration. -
