Before powering the dehumidifier for the first time by
switching the electrical disconnect, check the
following:
▪ Have the safety instructions and the locally
applicable regulations been observed?
▪ Is the dehumidifier properly and securely attached
to the ceiling?
▪ Is the air duct correctly dimensioned, properly
installed and adequately sealed?
▪ Have the hydraulic and electrical connections been
made according to these instructions and in
compliance with local regulations?
▪ Have the hydraulic and electrical connections been
made properly?
▪ Are the hydraulic connections of the water circuit
and the condensation drain properly sealed?
▪ Is the water circuit filled and properly vented?
▪ Is the dehumidifier properly earthed?
▪ Does the supply voltage match the value specified
in the technical data?
The supply voltage must correspond to the
specifications on the type plate with ±10 %
tolerance.
▪ Are all cover plates in the correct position and
adequately secured with the appropriate fixing
screws?
▪ Is the cover of the electronics box properly inserted
and secured with the appropriate screws?
After the device has been properly installed, the first
start-up may only be carried out after at least 2 hours.
If the water circuit is not filled, not properly vented or
there is no sufficient water supply available in the set
temperature range, the function of the machine may
be impaired.
As soon as the unit is supplied with voltage, it is in
STAND BY mode and the display shows two blue
stripes.
Now the input signals of the dehumidifier can be set
using the connected NEA SMART 2.0 control system.
After an input signal has been set, the fan starts right
away.
The input signal dehumidification (DH) additionally
activates the output signal ZONE VALVE and the
compressor starts with a time delay.
For correct wiring and configuration of the
NEA SMART 2.0 control system, refer to the relevant
technical information.
