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.
