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

 

 

2. 

Shut down of the electrical supply

 

CAUTION

: RISK OF ELECTRIC SHOCK. SHUT DOWN THE ELECTRIC SUPPLY OF THE 

HUMIDIFIER 

 

Turn off the main power supply to the humidifier. 

 

3.  Disconnection of heating element(s) 

 

Remove the high voltage connector located at the top right hand side of the mechanical compartment. 

o

 

Model SKE05: Unscrew the connector. 

o

 

Model SKE10 to SKE80: squeeze the locking ears of the high voltage connector and pull it apart.

 

 

4.  Disconnection of the other accessories. 

 

Disconnect  the  connector  from  the  water  level  sensor;  this  connector  is  attached  to  a  cable  that  enters  the 
mechanical compartment just below the high voltage connector. Squeeze the locking ear of the connector and 
pull it apart. 

 

Remove the connection to the high limit sensor (klixon), located on the top cover of the evaporation chamber. 

 

5.  Disconnection of steam hose and water pipe 

 

Remove the steam hose(s) at the top of the evaporation chamber. 

 

Remove the water drain/fill connection to the evaporation chamber. To do this, unscrew the nipple located on 
the lower right hand side of the evaporation chamber. 

 

6.  Removing the evaporation chamber 

 

The evaporation chamber may now be freely removed from the humidifier cabinet. 

 

CAUTION

: The evaporation chamber still contains 1 inch of water, ensure that you do not reverse this water on 

yourself. 

 

Make sure that your footing is secure when lifting out the evaporation chamber. On large humidifier (SKE50 to 
SKE80) it may weigh more than 15 kg. This operation may require another person to assist you in removing the 
evaporation chamber. 

 

7.  Opening of the evaporation chamber 

 

Remove the cover from the evaporation chamber. 

o

 

Model  SKE05:  Unlatch  the  3  latches  located  around  the  evaporation  chamber, 

caution:  these  latches 

are very tight, we recommend you to help you with a screwdriver or pliers to do

 

this. 

o

 

Model  SKE10  to  SKE80:    Turn  the  latches  of  the  4  or  8  latches  located  around  the  evaporation 
chamber. 

 

Remove the cover from the evaporation chamber.
