13.4 Humidifier
Maintenance
Clean the humidifier once a year and replace its tank.
Cleaning or replacing the steam tank
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:
Completely drain the tank using the manual drain program governed by the controller.
(See extract from the controller manual 20037,03.2015)
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 badly affected the tank must be replaced: Only the tank body and seal need to be changed.
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.
Procedure
Remove or wash the water supply valve. Check the inlet filter for clogging,
If the pump malfunctions or becomes worn, it must be replaced.
Inspect the water supply, steam supply and condensate drain pipes and replace them if necessary.
