➤ Proceed as shown (fig. 16, page 12).
7.10 Using the battery protection
The device is equipped with 3-stage battery protection. The battery protection prevents excessive discharging when the device is connected to a vehicle starter battery or maximises the use of a supply battery. Dometic
If the cooler is operated when the vehicle ignition is switched off, the cooler switches off automatically as soon as the supply voltage falls below a set level. The cooler will switch back on once the battery has been recharged to the restart voltage level.
NOTICE! Damage hazard
When switched off by the battery protection, the battery will no longer be fully charged. Avoid starting repeatedly. Ensure that the battery is recharged.
When the cooler is supplied by a starter battery, select the battery protection mode “MEDIUM” or “HIGH”. If the cooler is connected to a supply battery, the battery protection mode “LOW” is ideal. Dometic
➤ Proceed as shown (fig. 17, page 13).
7.11 Setting the display`s brightness
➤ Proceed as shown (fig. 18, page 13).
7.12 Switching on or off the compartments (only CFX3 75DZ, CFX3 95DZ)
You can activate each zone individually or both of them.
➤ Proceed as shown (fig. 19, page 14). Dometic
7.13 Using the ice maker (only CFX3 55IM)
- 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 cooler`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. Dometic
➤ Proceed as shown (fig. 20, page 14).
Filling the ice trays with water
➤ Remove the ice trays (fig. k 1, page 15) from the ice maker housing (fig. k 2, page 15).
➤ Remove the ice tray covers, fill with clean water and re-fit the cover, taking care to press the edge seal all the way around.
➤ Re-position the ice trays in the ice maker housing and close the lid.
Dry any water spillage from under the ice trays. This will reduce ice build up under the trays and make removal easier.
Removing the ice cubes
➤ Open the ice maker housing lid and lift under the front of the ice trays.
Removal may require additional force using two hands in high humidity conditions which may create an ice bond underneath the ice trays.
➤ 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 cooler:
➤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.
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.
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.
➤Following 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.
