6. When installing unit, take care not to damage electrical or other hidden utilities.
7. Check the details on the rating label for correct voltage, frequency, speed, phase
insulation class and IP rating.
8. Select the correct direction of rotation for the fan. Remove the rubber grommet fitted
in the sight port next to the terminal box to view rotation. Three phase units require
a trial connection. To change direction of rotation, interchange any two phase supply
leads.
9. It is the responsibility of the installer to ensure that all aspects of system design are
taken into consideration.
10. Due to the weight of units it is recommended that at least two people are involved in
the installation.
FAN MOUNTING
1. A duct mounted in-line fan. Short duct runs terminating close to the fan (i.e. within
1.5m) require suitable guards.
2. The fan can be mounted in a variety of ways and at any angle to suit the
application.
3. Plan the installation carefully, taking into consideration the safety points noted
above, before securely fixing the fan using appropriate screws, bolts, rubber
bushes, etc.
4. A range of accessories are available from Vent-Axia to assist installation including
flexible connectors, mounting feet, anti-vibration mounts and attenuators.
