USER MANUAL CombiNeo 4 (E) / CombiNeo 6 (E) (detartrage) TRUMA

Supporting documents

Further information on how to operate the CombiNeo can be found in the corresponding operating instructions. Further information on the vehicle can be found in the vehicle manufacturer's operating instructions.

The user must familiarise themselves with the vehicle's water system and how to operate the CombiNeo before the descaling process.

Carrying out the descaling process

• The CombiNeo must be descaled once a year or when a prompt to do so appears on the control panel.
• While it is possible to skip the descaling prompt on the control panel when it appears, the water heating function will be blocked if it is skipped several times. Space heating will still be available if this is the case.
• Descaling must be started and carried out via the control panel.
• It cannot be interrupted and resumed at a later time. If an error occurs during the descaling process or the process cannot be completed, the warning message is not reset and the process must be restarted from the beginning.
• The water heating block is cancelled automatically as soon as a descaling process (via the menu navigation) has been completed.

The entire descaling process takes about three hours. It consists of several steps, which are outlined below:

• Empty the CombiNeo and fresh water system
• Pour in descaling solution
- Carry out part 1 of the descaling programme
• Exchange the descaling solution
- Carry out part 2 of the descaling programme
- Empty and rinse the CombiNeo and fresh water system.

1 Preparations

Required utensils

• Commercially available citric acid-based descaling agent from camping specialists for producing 20 litres of descaling solution
• A suitable container (e.g. watering can) for mixing 10 litres of descaling solution

Ensure that the following conditions are met during the descaling process:

• Ensure access to fresh water.
• Ensure that a drain is available for grey water and used descaling solution.
• Ensure an adequate voltage supply for the duration of the descaling process.
  • Minimum water temperature in the vehicle: 8 °C
• Park the vehicle on a level surface. Please also refer to the CombiNeo operating instructions in this regard.

▶ Switch off space and water heating.

i Descaling mode can only be selected if space and water heating have been disabled.

i Space and water heating cannot be selected in descaling mode.

2 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.

NOTE

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

▶ Only vent CombiNeo via the hot water taps.

3 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.

NOTE

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

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

4 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').

Fig. 2

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).

NOTE

Faulty / incomplete descaling due to insufficient 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.

5 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.

NOTE

Descaling solution is released into the environment.

▶ Collect any escaping descaling solution beneath 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.

6 Repeating the programme

▶ Fill with descaling solution (see „3 Pour in descaling solution“ Page 10).
▶ Run the descaling programme again (see „4 Carrying out the descaling programme“ Page 11).
- Drain the descaling solution (see „5 Draining the descaling solution“ Page 12).

7 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.

8 Carrying out the rinsing programme

NOTE

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.

NOTE

Possible water damage due to water drainage issues

▶ Remain in the vehicle while rinsing and monitor 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.

① 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.
i Confirmation that the descaling process has been successful is displayed on the control panel.

The full range of functions of the device is available again.
