13 - MAINTENANCE
Cleaning procedure:
Remove the lters as instructed above,
To avoid damaging the blower nozzle, make sure that it is not too close to the nned surface.
13.4 - Humidier
Servicing
Clean the humidier 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 ow 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)
Cut the power to the unit by turning it o at the switch or removing the fuses on the line.
Remove the cylinder steam pipe.
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 ow of water and current).
If the electrodes are too damaged to allow regeneration, replace the tank: simply change the tank body and the gasket.
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 o for an extended period. Remember to always rst drain the
water from the tank and to cut the power supply.
Procedure
Remove or wash the water supply valve. Check the inlet lter 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.

If the humidier malfunctions (no steam produced).
Check the water conductivity: it must be between 350 and 1250µS/cm.
If frequent descaling is necessary, check the water hardness. It should be 15°f<TH<30°f.
