12. Service
12.1. General
The humidifier is set to give service demand on the alphanumeric display and on the CHECK light
after is has reached the service hours setting (see section 9.2- Programming)
The routine service is a cleaning of the evaporation chamber.
We recommend setting the service demand depending on the water quality, the frequency of
automatic drain cycles and the demand placed on the humidifier.
The manual cleaning frequency can be from every 2 months to once a year.
12.2. Evaporation chamber cleaning
WARNING
: RISK OF BURN. THE EVAPORATION CHAMBER AND ITS CONTENT CAN BE
EXTREMELY HOT, CHECK TEMPERATURE BEFORE HANDLING.
1. Cool down evaporation chamber
Set the front panel switch ''AUTO/OFF/DRAIN'' to DRAIN. The humidifier will command a drain cycle.
Ensure that the evaporation chamber is completely empty. When it is empty, set the front panel switch
''AUTO/OFF/DRAIN'' to AUTO, the evaporation chamber will be fill with cool water; the FILL light will be
illuminated.
As soon as the evaporation chamber is full of cool water, the FILL light will extinguish, Set the front panel
switch ''AUTO/OFF/DRAIN'' to DRAIN again.
At the end of this drain cycle, check the temperature of the evaporation chamber, to do so, open the front
door of the humidifier and touch the evaporation chamber with the back of your hand, If it is cool enough you
can go the sequence #2 if not repeat the cool down operation until it will be cool enough.
Set the front panel switch ''AUTO/OFF/DRAIN'' to OFF
