Humidifier
15.2.1
General information
If the ambient air at the installation location of the
LCP DX has a very low humidity, there is the danger of
device damage caused by electrostatic charges.
The "Humidifier" option allows the humidity to be in-
creased at the installation location. The option consists
of two components:
– Ultrasonic humidifier for producing the extremely small
droplets (approx. 1…5 μm diameter)
– Distribution pipe behind the evaporator for distributing
the droplets into the air flow
Because the droplets are created at the ambient tem-
perature, the air humidifier requires approx. 90% less
energy than a immersed electrodes humidifier.
A humidity sensor is also installed on the inlet side of the
LCP DX. The value acquired here is compared with the
setpoint for the humidity and the humidifier is activated
only when required.
15.2.2
Activating the humidifier
To activate the humidification function, proceed as fol-
lows:
Assign the "YES" value to the "Enable B5 humidity"
entry in the "Hc39" menu.

Also assign the "YES" value to "Enable" entry in the
"Ha35" menu.

Setting the humidity setpoint
DIP switches located below the humidifier allow the de-
sired value to be set for the setpoint humidity.
First remove the third fan from the top in order to reach
the DIP switches.
Set with the DIP switches no. 5 and no. 6 the required
value for the humidity setpoint from the following table.

Technical specifications
Note:
– The two options 6 (low temperature unit)
and 7 (high temperature condenser unit)
cannot
be installed together.
– When the "Dehumidification function" (op-
tion 4) is selected, also the "Electric heater"
(option 3) must be selected.
Note:
When in use, the humidifier performs an au-
tomatic flushing operation every 60 minutes.
When the humidifier is in standby mode, the
flushing operation is performed once every
24 hours.
