12. Faults and Messages / Conditions
Record display message and switch off the unit immediately in case of
malfunction.
The fault messages displayed depend on the humidifier type in use.
Risk of electrical shock!
Hazardous electrical high voltage!
All electrical work to be performed by certified expert staff (electricians
or expert personnel with eqivalent training) only.

Fault Blow-Down
Unit shuts off au-
tomatically
•
Blow-down pump has not been electrical-
ly activated
- Cable connections are faulty
- The relay on the main PCB is not opera-
ting
•
•
Check or replace cable connec-
tions
Measure voltage at the PCB ter-
minals against N or replace
PCB
•
Defective blow-down pump
•
Replace blow-down pump.
•
Solenoid valve does not close properly. Water
level in the cylinder sinks very slowly even
though blow-down pump flushes out water.
•
Check solenoid valve.
•
Blow-down pump operates, but no water is
pumped out, i.e. the cylinder drain is blocked.
•
Thouroughly clean steam cylinder
and base to prevent short-term
blockage from reoccurring
•
Blow-down pump is blocked up with mineral
deposits.
•
Check blow-down pump, drain as-
sembly and cylinder for mineral de-
posits and clean.

Fault
Max.-Level
Unit shuts off auto-
matically.
•
If the water level “max. level” is reached, the
pump switches on and drains the cylinder un-
til the water level lowers to “operation.” If the
“max.-level” is reached five times, “max.-lev-
el” is displayed.
•
Air pressure in the duct is too high. Duct air
pressure enters the cylinder via the steam
hose. Water is forced into the drain.
•
Reduce air pressure or detach vent
pipes from the unit and place higher
•
Solenoid valve does not close properly. Water
level in the cylinder rises slowly even though
the solenoid valve has not been activated.
•
Check solenoid valve.
•
Water is supplied even thoough the steam hu-
midifier is switched off. Solenoid valve re-
mains open.
•
Clean solenoid valve.
•
Inlet solenoid valve is receiving a constant
electric signal. (If the unit is turned off, water
feeding stops.)
•
The relay on the main PCB has
stuck. Measure voltage at PBC-ter-
minal 10 against 15.
