■ Maintenance
Clean the humidifier once a year and replace its tank.
■ Cleaning or replacing the steam cylinder
This operation is necessary when the deposits that form on the active surface of the electrodes prevent the correct flow of current
(alarms E08, E06).
To remove the tank:
- Drain the cylinder completely via the manual drain programme actuated by the control (See extract from the control manual:
paragraph 6.2, parameter no.911)
- Cut the power to the unit by turning it off at the switch or removing the fuses on the line,
- Remove the tank steam hose,
- Disconnect the main electrodes and remove the pins from the level electrodes,
- Remove the retention spring from the cylinder and lift the tank up and out.
In general, the steam tank can be reused after being descaled (scale on the electrodes prevents the free flow of water and current).
If the electrodes are too damaged to allow regeneration, the cylinder must be replaced: only the cylinder body and the gasket require
replacement.
Check the gasket and replace it if need be. Put the tank back in place by following the above steps in reverse order.
■ Cleaning the unit and seasonal servicing
The unit must be checked and cleaned once a year or after it is shut off for an extended period. Remember to always first drain the
water from the tank and to cut the power supply.
