Maintenance interventions on the humidifi er should be carried out by
CAREL Support Service or by specifi cally qualifi ed staff .
Important: before proceeding with any operation:
•
cut off the power supply setting the master switch of the machine to
"OFF";
•
close the shut-off valve of the water supply line.
•
ON/OFF swithc on the device cuts off power to electronic circuit only,
not to other electrical parts!

Non-routine maintenance is carried upon every time scheduled
maintenance request (code "CL" on display). Therefore, it is necessary to
perform complete maintenance of the humidifi er and reset the hour
counter.

14.3 Maintenance frequency

Maintenance frequency depends on the amount of water and steam
generated.
Tap water
Water hardness
Daily operating hours
No. of maintenance/ year
Demineralised water
The use of demineralised water minimises maintenances times.
Note: we recommend you carry out non/routine maintenance at
least once a year, regardless of the operating hours and the data
shown on the hour counter.
