To reverse the lid opening, proceed as shown:
CFX5 55IM

CFX5 75DZ, CFX5 95DZ

Selecting the temperature units

• Select the temperature as shown.
  

Operation

Saving energy

• Choose a well ventilated location which is protected from direct sunlight.
• Allow warm food to cool down first before placing it in the cooling device to keep cool.
• Do not open the cooling device more often than necessary.
• Do not leave the cooling device open for longer than necessary.
• If the cooling device has a basket: For optimal energy consumption, position the basket according to its position on delivery.
• On a regularly basis, ensure the lid seal still fits properly. Avoid unnecessarily low temperatures.

Connecting the cooling device

Fire hazard
Do not connect more than one power source to the product at any given time. Electrical system damage can occur and may result in a fire.

Connecting to a DC source
NOTICE! Damage hazard
For protection of the device the DC cable supplied includes a fuse inside the plug. Do not remove the fused DC plug. Only use the DC cable supplied.

• Connect the device to a DC source as shown.
  

Connecting to the Portable Battery Pack PLB40 or the Hardwiring Kit HWK-DC (accessories)

• Connect the device to PLB40 or HWK-DC as shown.
  

Connecting to an AC power supply

Electrocution hazard

• Never handle plugs and switches with wet hands or if you are standing on a wet surface.
• If necessary, seek advice from a trained technician.

• Connect the device to an AC power supply as shown.
  

Using the battery monitor

The cooling device is equipped with a battery monitor that provides a 3-stage battery protection. The battery protection prevents excessive discharging when the cooling device is connected to a vehicle starter battery or maximises the use of a supply battery.
If the cooling device is operated when the vehicle ignition is switched off, the cooling device switches off automatically as soon as the supply voltage falls below a set level. The cooling device will switch back on once the battery has been recharged to the restart voltage level.
NOTICE! Damage hazard
When switched off by the battery monitor, the battery will no longer be fully charged. Avoid starting repeatedly or operating current consumers without longer charging phases. Ensure that the battery is recharged.
NOTE
When the cooling device is supplied by the starter battery, select the battery monitor mode "HIGH". If the cooling device is connected to a supply battery, the battery monitor mode "LOW" will suffice.

• Set the battery monitor as shown.
  

NOTICE! Risk of overheating
Ensure at all times that there is sufficient ventilation so that the heat that generated during operation can dissipate. Ensure that the ventilation slots are not covered. Ensure that the device is sufficiently far away from walls and other objects so that the air can circulate.
NOTICE! Damage hazard from excessively low temperature
Ensure that only those objects are placed in the cooling device that are intended to be cooled at the selected temperature.

NOTE
When operating with the battery:

• When voltage is < 8 V the display switches off automatically.
• When voltage is ≥ 8 V and ≤ 12 V the display may show "!ALERT - Voltage low" depending on the battery monitor mode setting.

Using the display

Display states:

Navigating through the menus
The highlighted menu is selected.

• Press to navigate upwards.
• Press to navigate downwards.

Choosing a menu

• Press to select the required menu.

• Set the display brightness as shown.
  

Switching a compartment off or on (dual zone devices only)

You can activate each zone individually or both of them.

• Activate or deactivate the zones as shown.
  

Using the ice maker (CFX5 55IM only)

NOTE

• Independent of the main compartment's temperature setting, the ice maker zone is designed for making ice cubes if the ice maker is switched on.
• The cooling device's energy consumption increases with ice maker on. Therefore you should switch off the ice maker if it is not needed.
• The factory setting for the ice maker is OFF.

Tips for using the ice maker

• The ice maker makes ice fast for a number of hours after switching on and then automatically goes into an ice maintenance mode to reduce energy consumption. If multiple batches of ice are required as quickly as possible, switching the ice maker off and back on will set it back into fast ice making mode. Repeat as required.
• Low freezer temperature settings in the main compartment may not be maintained in high ambient temperature conditions with the ice maker switched on.
  • To turn the ice maker on or off proceed as shown:
    

Filling the ice trays with water

• Remove the ice trays ( Fig. 1) from the ice maker housing ( Fig. 2).
  

1. Open the ice maker housing lid and lift under the front of the ice trays.
2. Remove the ice tray covers and twist trays to release the ice cubes.

Removing the ice maker housing
The ice maker housing can be removed for cleaning or when not in use to increase usable space inside the cooling device.

• Lift the housing at one end until the lug unclips, then remove.
• Reverse procedure for re-fit, pushing down on lugs to snap into position.

Cleaning and drying the ice maker

• When not in use clean and dry the ice trays and inside the ice maker housing to prevent mould.
• After extended periods of non-use clean the inside of the ice trays with a mild dish washing solution and rinse with clean water prior to use.

Using Bluetooth and Wi-Fi

Downloading the Mobile Cooling app
The cooling device can be monitored and controlled via Bluetooth or Wi-Fi using an app that you can install on a compatible device.
Download the Mobile Cooling app.

Setting the Bluetooth signal and connecting to the app
The cooling device can be monitored and controlled via Bluetooth. To do so pair the cooling device with your Bluetooth device.
NOTE

• Pairing must be done within the Mobile Cooling app, not in device settings.
• There is no password required for Bluetooth connection.

• Set the Bluetooth signal and connect the app as shown.
  

Setting the Wi-Fi signal

• Set the Wi-Fi signal as shown.
  

Operating Bluetooth and Wi-Fi

• Follow the instructions in the mobile cooling app.
• The Bluetooth or Wi-Fi LED lights up when the cooler is connected.

Resetting to factory settings

The reset function changes all display menu and app fields to the original factory settings.

• Reset the device to factory settings as shown.
  

USB port for power supply

The USB port allows you to charge small devices like mobile phones and mp3 players.
NOTE
Ensure that any small device connected to the USB port is compatible with 5 V/2.5 A operation.

• Use the USB port as shown.
  

Defrosting the cooling device

Humidity can form frost in the interior of the cooling device or on the evaporator. This reduces the cooling capacity.
NOTICE! Damage hazard
Never use hard or pointed tools to remove ice or to loosen objects which have frozen in place.
To defrost the cooling device proceed as follows:

1. Remove the contents of the cooling device.
2. If necessary, place the contents in another cooling device to keep them cold.
3. Switch off the cooling device.
4. Leave the lid open.
5. Wipe off defrosted water.

1. Disconnect the power supply to the device.
2. Remove the connection cable.
3. Pry out the fuse insert (Fig. 2) with a screwdriver.
4. Replace the defective glass fuse with a new one of the same type and rating (Fast acting, 4 A, 250 V ).
5. Press the fuse insert back into the housing.
6. Reconnect the power supply to the device.

Replacing the DC fuse

1. Disconnect the power supply to the cooling device.
2. Pry out the fuse cover (Fig. 3) with a screwdriver.
3. Reverse the fuse cover and use hook to remove the defective blade fuse.
4. Push in a new fuse of the same type and rating.
   • Single zone devices: 10 A
   • Dual zone devices: 15 A
5. Re-fit the fuse cover.

Cleaning and maintenance

Electrocution hazard
Ensure that the cooling device is disconnected from the power supply before any cleaning or maintenance work.

NOTICE! Damage hazard

• Never clean the cooling device under running water or in dish water.
• Do not use abrasive cleaning agents or hard objects during cleaning.
• Occasionally clean the device interior and exterior with a damp cloth.
• Ensure that the air inlet and outlet vents on the cooling device are free of any dust and dirt, so that heat can be released and the cooling device is not damaged.
