Descale CombiNeo

Emptying the fresh water container and CombiNeo:

• Switch off the water pump (Fig. 1-5).
• Turn on all hot water taps (Fig. 1-2, in the kitchen and bathroom) (set pre-selection mixer or single-lever taps to ‘warm’).
• Place empty containers under the drain hose of the FrostControl (Fig. 1-4) and the drain valve of the fresh water system (Fig. 1-6).
• Open FrostControl. To do this, turn the rotary knob on the top through 90°.
• Open the drain valve of the fresh water system.
• Wait until water stops emerging from the drain hose of the FrostControl and from the drain valve of the fresh water system.
• Close FrostControl. To do this, turn the rotary knob on the top through 90°. Then press the pushbutton on the front side of the FrostControl.
• Close the drain valve of the fresh water system.
• Turn the hot water taps off.

Inadequate descaling due to the CombiNeo water container not being emptied completely.

• Only vent CombiNeo via the hot water taps.

Pour in descaling solution

• Mix 10 litres of descaling solution in a suitable container (e.g. watering can) according to the manufacturer's instructions.
• Pour descaling solution into the empty fresh water system (Fig. 1-1).
• Switching on the water pump
• Turn on all hot water taps in the kitchen and bathroom (set pre-selection mixer or single-lever taps to ‘warm’). Leave the fittings open for as long as it takes for the descaling solution to flow without interruption.
• Turn the hot water taps off.

Damage to the water system due to the descaling solution being too "harsh"

• Only use descaling solution in accordance with the manufacturer's instructions.

Carrying out the descaling programme

Starting the descaling programme via the control panel:

• Select the 'Descaling' submenu under 'Settings'.
• Start the descaling programme in the 'Descaling' submenu (Fig. 2) ('Start descaling').

Note: the appearance of the display varies depending on the control panel version or vehicle configuration in use

• Wait for the descaling programme to end.
• The descaling programme lasts 60 minutes. The remaining time is shown on the display.
The descaling programme is complete when the start screen is displayed again in the 'Descaling' submenu (Fig. 2).

Faulty / incomplete descaling due to insuffi- cient descaling solution in the CombiNeo's water container.

• Keep FrostControl closed while the descaling programme is running.
• Keep taps turned off while the descaling programme is running.

Draining the descaling solution

• Switching off the water pump
• Turn on all hot water taps in the kitchen and bathroom (set pre-selection mixer or single-lever taps to ‘warm’).
• Place empty containers under the FrostControl drain hose and the drain valve of the fresh water system.
• Open FrostControl. To do this, turn the rotary knob on the top through 90°.
• Open the drain valve of the fresh water system.
• Wait until there is no more descaling solution escaping from the FrostControl drain hose or the drain valve of the fresh water system.
• Close FrostControl. To do this, turn the rotary knob on the top through 90°. Then press the pushbutton on the front side of the FrostControl.
• Close the drain valve of the fresh water system.
• Turn the hot water taps off.

Descaling solution is released into the en- vironment.

• Collect any escaping descaling solution be- neath the FrostControl drain hose.
• Dispose of the descaling solution in the correct manner.

The descaling solution has not been completely drained.

• Keep cold water taps turned off.

Repeating the programme

• Fill with descaling solution (see „3 Pour in descaling solution“).
• Run the descaling programme again (see „4 Carrying out the descaling programme“).
• Drain the descaling solution (see „5 Draining the descaling solution“).

Filling with fresh water

• Fill approx. 50 litres of fresh water into the empty clean water system (or fill completely if the tank is small).
• Switching on the water pump
• Turn on all hot water taps in the kitchen and bathroom (set pre-selection mixer or single-lever taps to ‘warm’). Leave the fittings open until the fresh water flows without interruption.
• Turn the hot water taps off.

Carrying out the rinsing programme

Descaling solution enters the body, skin contact with descaling solution due to incomplete or incorrect rinsing

• Fill the fresh water system with sufficient fresh water before rinsing.
• Keep FrostControl closed.

Start the rinsing programme via the control panel:

• Select the 'Descaling' submenu under 'Settings'.
• In the 'Descaling' submenu (Fig. 2), start the rinsing programme ('Start rinsing').
Turn on the hot and cold water taps (set pre-selection mixer or single-lever taps to the centre position). Leave them open for the duration of the rinsing process.

Possible water damage due to water drainage issues

• Remain in the vehicle while rinsing and mo- nitor the rinsing process.

Risk of damage to the water pump and incomplete rinsing due to running dry.

• Make sure that the fresh water system does not run empty during the rinsing process. If necessary, top up with water during the rinsing process.

• The rinsing process takes approx. 5 min. The remaining rinsing time is displayed on the control panel.
• Turn off the taps after rinsing is complete.
• Confirmation that the descaling process has been successful is displayed on the control panel.
