The leveling feet on the bottom of the unit ensure exact alignment
of the unit during mounting.
For alignment of the unit loosen the nuts and adjust position of the
support disc manually using a wrench. Then tighten the upper and
the lower nut.
To attain the best performance of the unit and to minimize
turbulence-induced air pressure losses while mounting, connect
straight air duct sections to the unit spigots.
Minimum straight air duct length:
equal to 1 air duct diameter on 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 fan, the spigots may be covered with a protecting grille or other protecting device with mesh width not more than ½ inches.
Fasteners for the unit mounting are not included into delivery set and should be ordered separately.
While selecting appropriate fasteners consider material of the mounting surface as well as the weigh of the unit, refer to the technical
data. For selection of the fasteners for unit mounting please refer to a service technician.
INSTALLATION AND CONNECTION OF SENSORS
The unit provides for the installation and connection of one of the sensors – an humidity sensor or a CO2 sensor.
The sensors are not included in the delivery set and can be ordered separately.
Humidity sensor installation and connection
The humidity sensor must be attached inside of the extract air duct.
Attach the sensor to the insert. Open the unit, remove the upper part of the protective casing and install the insert with the sensor on
the bracket located on the wall of the exhaust duct. Connect the sensor connector to the connector with the cable from the control
unit (installed by the manufacturer).
After connecting the humidity sensor, it is necessary to change the control configuration in the controller. Contact the product Seller
for doing that.
