INSTALLATION AND SET-UP
HV2 HUMIDITY SENSOR INSTALLATION AND CONNECTION (FOR UNITS WITH A14 AND A21 CONTROL)
The HV2 humidity sensor is not included in the delivery set and is available as a specially ordered accessory.
The humidity sensor must be installed prior to the unit mounting.
Install the humidity sensor through the extract spigot into the mount on the extract air duct panel. After that connect the humidity
sensor plug to the respective socket on the control unit, refer to the External wiring diagram.
UNIT INSTALLATION
To attain the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section
to the spigots while installing.
Minimum straight air duct length:
• equal to 1 air duct diameter on the intake side
• equal to 3 air duct diameters on outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects.
To prevent uncontrollable access to the fans, the spigots may be covered with a protecting grille or other protecting device with mesh
width not more than 12.5 mm.
While installing the unit, ensure convenient access for subsequent maintenance and repair.
The unit must be mounted on a flat floor.
Installing the unit to an uneven surface could lead to the unit’s casing distortion and operation disturbance.
Do not expose the unit to direct sunlight.
The plate opposite to the service side must be fixed with screws (included in the delivery set) before installation.
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
