Droplet separator

Depending on the type of extraction, the separator frames can be 

disassembled as follows:

 

Side extraction:

Side

extraction

Retaining

bracket

Frontal

extraction

1.  Remove the separator's side access panel (4 screws)
2.  Pivot the 2 retaining brackets to release the separator (1 at 

the top, 1 at the bottom)

3.  Pull the separator towards you to remove it from the unit

 

Frontal extraction:

1.  Open the separator's access door (opening handle)
2.  Pivot the 2 retaining brackets to release the separator frames 

(1 at the top, 1 at the bottom)

3. 

Detach the frame from its runner in the direction of the air flow 

(removal via a recess in the runner)

4.  If the separator is made up of several frames, slide the second 

one to position it opposite the recess and detach it, etc.

When refitting, remember to lock the frames using the retaining 

brackets.

Humidifiers

IMPORTANT: The type of humidifier used and the water quality 

must comply with the regulations in force.

The upper limit value for non-pathogenic bacteria is 10,000 CFU/

ml (Colony Forming Units). However, it is best to check and clean 

the air handling unit from 1,000 CFU/ml onwards (standard EN 

13053). An overflow with siphon must be installed on adiabatic 

humidifiers. UV treatment and cleaning are recommended.

 

Steam humidifier 

Ordinary maintenance simply involves having the steam cylinder 

replaced and the unit cleaned each year. This must be carried out 

by a qualified technician.

 

Cleaning or replacing the steam cylinder

This is necessary when deposits on the active surface of the 

electrodes prevent normal current flow (alarm E06, E08).

Disassemble the cylinder as follows:

 -Press the manual drain button to completely empty the water 

in the cylinder,

 -Remove the cylinder steam hose,

 -Disconnect the main electrodes and the level electrodes,

 -

Remove the retaining spring and twist off the cylinder.

The steam cylinder can generally be reused after descaling (scale 

on the electrodes prevents the free flow of water and current).
Unscrew the clamp and remove the bottom filter. Flush away any 

mineral debris in the cylinder under running water and clean the 

grilles with an off-the-shelf cleaner.

Replace the cylinder if the electrodes are too badly corroded. Only 

the cylinder body and O-ring need to be changed (do not change 

the capping ring, seat or filter). 

Reassemble the cylinder by following the above steps in reverse 

order after checking or replacing (if necessary) the seal between 

the coupling and the drain unit.

Cleaning the unit and seasonal servicing

Check and clean the unit once a year. Drain the unit and 

disconnect it from the power source before doing so:

 -Disassemble or wash the water supply valve and check the 

cleanliness of the inlet filter,

 -Remove the drain unit and clean the lines and nozzles,

 -Inspect the water supply, steam supply and condensate drain 

pipes and replace them if necessary.

 

Servicing frequency

 -Check the connections each time the air handling unit is 

turned on,

 -Check the condition of the cylinder. If necessary, replace it 

once every three months,

 -Retighten the electrical connections and check the 

components and correct diffusion of steam each year.

For further information, refer to the manufacturer's instructions 

delivered with the unit.
