8-4 Humidifier
Servicing
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:
Press the manual discharge button to drain all the water,
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. 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.
The pump must be replaced if it malfunctions or shows signs of wear.
Check the water supply pipes, steam pipes and condensation drain pipes. Replace them if necessary.
Supply valve
If the humidifier fails (no longer produces steam), check the conductivity of the water.
It should be between 350 and 1250 µS/cm. If frequent descaling is necessary,
check the water hardness. It should be between 60 and 120 mg/l calcium.
