Symbols and terms used in this document
Some symbols are used in this manual or on the product.
These symbols have the following meanings :

Ventilation clearance

• Slots and openings in the body are provided for ventilation; to ensure reliable operation and to protect against overheating, these opening should never be blocked or covered.
• A minimum clearance of 60mm is recommended on the back, side and front of the fridge for ventilation.
• This product should never be placed in a built-in installation with limited airflow unless adequate ventilation is provided.
  Closed compartments should provide for cool air intake and warm air exhaust.

Guide to electrical wiring
This appliance is optimised for mobile use. Standard 12V accessory sockets used in many motor vehicles can be used but may result in unreliable operation due to thin wiring and high voltage loss. For long-term reliable operation in a motor vehicle or other mobile application, it is recommended to install dedicated 12V / 24V wiring and suitable DC-rated connectors.

A minimum cable gauge of 4mm2 (12 AWG) should be used between the fridge and power source (battery). For safety, a 15A fuse should be installed close to the battery on the positive cable.

When connecting the AC supply, make sure the cable plug is appropriate for the region or country of use and the cable is not damaged. Verify the AC supply voltage is within the fridge operating voltage range. Do not place AC plug adaptors or power supplies on or behind the fridge.
Protect all cables from potential damage, particularly in applications where the fridge or cables are likely to move, such as in sliding or drawer systems. Protect the cables from sharp edges and areas that may be exposed to high heat.

• DO NOT use a modified or damaged power cable. Doing so may result in serious injury or damage to the appliance.
• If dedicated wiring is installed to supply the fridge, a 15A fuse should be fitted on the positive cable near to the battery.
• Before installation of any additional wiring, check that this action will not void any vehicle warranty or service agreement.

Side-mount models do not have USB charge ports.

Latches and Handles

Depending on the model, the fridge will have one or two door latches which are used to keep the main door closed securely.
Stainless steel latches provide a locking hole that can be used with locks or tamper-evident seals.
The plastic latches are only on the NL35 and NL45 models.

Bottle-opener strip

Each door handle has an integrated bottle-opener strip.
This can be used to remove standard bottle caps.
Hook the bottle cap on the metal strip and pull the bottle upwards against the handle to detach the bottle cap.

USB charge ports

There are two independent USB-charging ports available on the side.
Each port is capable of fast-charging up to 24W maximum power and will be active when the fridge is connected to DC or AC power sources.

USB charge ports remain active if the fridge is in standby mode.
USB charge ports are not affected by low-battery protection.

Securing fridge in a mobile application

• Using a base plate (optional accessory)
  It is recommended to use a base-locking plate
  (available separately) to secure a fridge in a mobile application.
  The base plate is usually bolted to the vehicle load area or onto a sliding mechanism and allows the fridge to be secured without additional straps.
  The fridge slide-locks onto the base-plate and is secured in place with locking pins.

• Using straps
  Carry handles each feature a tie-down slot that can be used with standard 25mm straps.
  These can be used to secure the fridge to tie-down points.
  Take care not to over-tighten straps as this can cause damage to the handles or fridge body.

Only use the provided tie-down slot. Do not strap to the folding hand-hold.

Connecting power

DC supply input
For battery-powered applications, connect the supplied DC cable (or approved replacement) into the DC input socket and ensure it is properly inserted.
Connect the other end to the DC power source.

Ensure polarity is correct before connecting the DC supply. Incorrect polarity may result in permanent damage.

AC supply input
For AC power sources, connect the supplied AC cable (or approved IEC cable) to the AC input socket and ensure it is properly inserted.
Connect the other end to the AC supply.

AC and DC supply can be connected simultaneously. The fridge will switch between the available power sources automatically. Priority is given to AC power.

User interface
Depending on the fridge model, the control panel will provide either a Single or Dual temperature interface.
Both types provide Battery Protection and Speed control settings as well as Fault and Run status indicators.

Start display sequence

When power is applied to the fridge, the control panel will display a start sequence.
During this initialization period, all digits will be turned on, followed by a version number.
This identifies which program version the fridge is running.

The sequence ends with a display of the currently-measured temperature. The fridge is now ready for operation.

Single compartment models

Dual compartment models will show the configured model on the left display and the program version on the right display.

• Display test.

• Configured model and program version.
  (NL50 shown in this example)

• Current temperatures are shown

If the configured model number does not match the physical model of the fridge there can be unexpected behavior. Contact technical support for instructions on how to reset the model configuration.

Battery protection

Battery protection is used to prevent excessive discharge and potential damage to a source battery. The choice of setting will depend on the specific application.
Press and hold the battery button to cycle through available options.

• HIGH is recommended when powering the fridge from a vehicle main battery. This provides the highest protection level.
• MED is recommended for most applications where a deep-cycle auxiliary battery is used to power the fridge.
• LOW can be used to prioritize fridge run-time over battery discharge.

Speed control

Under normal conditions, the fridge will automatically balance cooling performance and efficiency.
This is preferred for most applications.

TURBO mode will increase cooling performance but at the expense of increased energy consumption.

The TURBO mode can be toggled by holding the TURBO button for 3 seconds.

TURBO mode may increase power consumption.

Standby mode

The fridge can be put into a standby mode by holding the UP button for 3 seconds.
(right compartment control on Dual models)
Press and hold the UP button again to exit standby and return to normal operation.
The ON/OFF state is saved if power is removed. This setting is restored when power is applied.

When in standby mode, the fridge interior light and USB ports will remain operational.

Choosing the temperature display units (°C / °F)

The temperature display units can be toggled between °C / °F by briefly pressing both UP and DOWN buttons together.
The display will then change to the selected units.

On Dual models, press the two buttons on the Right Compartment.

Setting the desired temperature

• The compartment temperature can be adjusted by entering the SET mode on the respective compartment :
  Hold the DOWN button until the display begins to flash.
  The procedure is the same for both controls on
  Dual-compartment models.

• When the display is flashing, press UP or DOWN to increase or decrease the compartment temperature.
  When the desired value is reached, release all buttons.
  After 10 seconds, the display will stop flashing and the new setting will take effect.
  The display will then return to showing the current temperature.

Disabling a compartment – dual models only

On Dual models, it is possible to independently turn off the left or right compartment.
This can be used to reduce power consumption if only one compartment is needed.
To turn off a compartment, enter the settings mode.
Increase the temperature setting until “OFF” is displayed. Release the buttons.
To re-activate the compartment, enter set mode and set any desired temperature.

RUN indicator

The RUN status indicator will show when the fridge compressor is running. Dual compartment models will have two RUN indicators which will show which compartment is being cooled.

• OFF – The compartment is not cooling.
• ON – The compressor is running and the compartment is being cooled.

Flashing (1/2 second on, 1/2 second off) –
Start delay before compressor runs.
Flashing (1 second on, 1 second off) –
Compressor is slowing down before stopping.

Fault diagnostics
There are several parameters being monitored by the fridge during operation.
If a fault is detected, it will be identified by flashing the Fault-ID indicator between 1 and 6 times within a 4-second period. The number of flashes will indicate which fault has been detected.

1 flash

| Low voltage – The DC supply voltage is lower than the chosen battery protection level. Check the battery and all wiring from the battery. This can also occur with an AC power supply fault.
---|---

2 flash

| Fan over-current – This can occur if the ventilation fan is blocked or damaged. Check the fan intake for signs of excess dust or debris. This can also occur if the fan has failed.

3 flash

| Motor start error – The compressor is unable to start. This can occur in extreme environments with high temperatures and heavy loads. This error can be temporary and may clear automatically.

4 flash

| Minimum speed error – The compressor is unable to maintain a minimum speed. This can be an electronics failure or over- pressurised system.

5 flash

| Over-temperature – The electronic driver is too hot and has shut down. This can occur if the ventilation intake is blocked or the fan is damaged.

6 flash

| Driver failure – The electronic driver has suffered a failure.   This may be permanent damage and may require replacement.

In addition to the 6 flash codes, if a fault is detected on the internal temperature sensors, a “PrF” message is displayed. This indicates a “Probe Failure” and that the sensor may need to be replaced.
Dual models have two sensors. A “PrF” message may be displayed on either the left or right display – this will show which of
the two sensors is problematic.

NL CONNECT Mobile application

Legacy SMART fridges include Bluetooth® wireless technology that allows the status and settings to be monitored by a connected mobile device.
The NL CONNECT application allows the user to observe the fridge status, adjust settings and be notified of fault conditions.

The NL CONNECT application is available for iOS and Android devices and can be downloaded from the respective APP stores.

You will not need to select the device from the scan list.

Keep screen on option
This option will prevent the screen of the mobile device from turning off while the APP is open.

Note – this will increase battery use on the mobile device.

Defrosting
It is normal for ice to accumulate on the cooling surfaces of a freezer. This will be more significant in humid environments. Increased ice build-up will reduce cooling performance and should be removed periodically.

• Before defrosting, remove any contents of the fridge or freezer compartments.
• Disconnect all power cables from the fridge and open the main door.
• Allow any ice or frost to melt.
• Use a soft cloth to remove melting ice and water.
• Do not use sharp objects to scrape ice from the cooling surfaces.

It is best to dry the interior before turning on the fridge.

Care and cleaning

Use a soft cloth with mild detergent if necessary to clean the exterior of your fridge.
Make sure surfaces are dry before storage.

• The interior should be cleaned regularly to prevent bacteria and odours from forming.
• Use a soft cloth with mild detergent or anti-bacterial soap, do not use abrasive or strong chemicals.
• Do not use ammonia-based cleaning agents or strong acids.
• Do not use sharp tools to remove ice on the cooling surfaces.
• The ventilation intake on the rear of the fridge may accumulate dust or debris over time. Check the vents regularly and blow out any dust, remove any loose debris.

A blocked air intake can result in poor cooling performance and increased power consumption.

Storage when not in use

When your fridge is not in use, it is best to clean the interior and exterior prior to storage. Turn off the fridge and remove power cables.
It is recommended to keep the door open to allow air to circulate inside the fridge.
This will help keep the interior dry and prevent odours.

A door latch can be used to keep a door open as indicated below

TIP – Place baking soda in an open container and position inside the fridge. This will help to absorb odours.

Adjusting door tension

Over time, the door seal may compress or deform.
This is normal and it may be necessary to adjust the door tension.

Adjustable door hinges

1. Unclip the door latches.
2. Loosen the 3 lower screws on each door hinge.
3. Apply light, even pressure on the back edge of the door. The door seal should be lightly compressed.
4. Tighten the 3 screws on each hinge.
5. Close the door latches and check their tension.
   They should not be loose or overly tight.

Adjustable door latches – NL35 and NL45 only
The door latches on the NL35 and NL45 models can be adjusted to increase or decrease door tension on the opening edge of the fridge.

To adjust tension :

1. Unclip and fully open the door latch.
2. Tighten the brass nut to increase tension or loosen the nut to decrease tension.
3. Make small changes, checking the tension between each adjustment. The latch should operate easily with light force. Do not over-tighten.

Take care not to over-tension the door catches or hinges as this can over- compress the door seal or damage the door catch components.

Removing door seal

The door seal can be removed for cleaning simply by pulling from one corner. Clean and dry the seal and replace by pushing it firmly into the recessed slot in the lid.
Over time the door seal may become less flexible and not seal completely. Remove the seal and place in a warm environment, such as in the sun.
This can help the seal to return to its original shape.
If the seal is damaged, replace with a new one.
(spare part available)

Removable hinges – optional accessory

Applications with limited space where it is not possible to fully open the main door can benefit from removable hinges.
These replace the standard hinges and allow the door to be completely removed after opening partially.
Remove each of the standard hinges and replace with a removable hinge. Adjust the door tension if necessary.

Recommended temperature settings

Optimising efficiency

Follow these simple tips to reduce your fridge’s energy consumption :

• Keep your fridge in a cool, well-ventilated area.
• Set the internal temperatures appropriate for the contents. Setting temperatures colder than necessary can increase energy consumption.
• Avoid opening the main door more than necessary.
• Load pre-frozen foods into the freezer or freeze the contents when AC power is available.
• Turn off an unused compartment on a Dual-compartment model to reduce energy use.
• Dual-compartment models often have one compartment with thicker insulation and seperate lid. Use this as the freezer if a fridge + freezer combination is used.
• With Dual-compartment models, defrost frozen foods by moving them from the freezer to the fridge compartment. This will help to keep the fridge contents cool and also prevent bacterial growth. Note – This will increase the defrost time so careful planning is required.

Solar panel, battery and inverter sizing
For most remote applications where solar is the primary energy source, a solar panel size of 100-150W is recommended if 6-8 hours of direct sunlight is available each day.
This should be combined with a battery of at least 100Ah and solar regulator suitable for the solar panel used.
A larger battery capacity will allow the fridge to run longer between re- charges and can extend battery life by reducing the chance of deep discharge.
If the fridge is powered by an AC inverter or generator, it should have a rating of 150W or more.
The inverter or generator output must be within the fridge AC voltage limits.
Large voltage surges can cause permanent damage to your fridge.

Note – It is more efficient to power a fridge directly from a battery than to use an inverter.
