READ AND SAVE THESE INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. INSTALLATION AND WIRING
INSTRUCTIONS SHOULD BE LEFT WITH END USER.
Air moving equipment may present mechanical, electrical or noise hazards. To minimise risks associated with these
potential hazards, it is essential that safety, installation, operation and maintenance instructions are followed.
Implementation of these instructions should always be undertaken by technically competent personnel.
Potential mechanical hazards must be eliminated by guarding against access to the rotating parts whilst the air
moving equipment is operating. A range of guards are available for this purpose from Vent-Axia.
Installation work, both mechanical and electrical, must be undertaken in accordance with the safety and installation
instructions before switching on the unit.
Maintenance work should not be attempted before first switching Off and isolating the fan and its control from the
electrical supply and ensuring that it cannot be accidentally turned back on again. It is essential to ensure that
rotating parts have come completely to rest before maintenance work commences.
Air moving equipment may generate unacceptable noise levels when in operation. It may be necessary to take
appropriate action to reduce sound levels. A range of products are available for this purpose from Vent-Axia.
IMPORTANT
1. All electrical connections should be made by a properly qualified electrician. The fan must be sited and connected
in accordance with current IEE Wiring Regulations, BS7671 (U.K.), or the appropriate standards in your country.
2. DO NOT use this appliance when the following are generated or present: Excessive grease or oil laden air,
corrosive or flammable atmospheres.
3. When the fan is installed in a room containing a fuel burning appliance, the installer must ensure that the air
replacement is
adequate for both the fan and the fuel burning appliance.
4. If a fan is used to supply air into a room, the installer must ensure that the fan intake is located at least 600mm
away from any
flue outlet.
5. site away from direct sources of heat, ambient temperature range -40 o C to +70 o C.
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.
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 larger units it is recommended that two people are involved in the installation.
FAN MOUNTING
CASED AXIAL FANS
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 coupling flanges, flexible
connectors, mounting feet, anti-vibration mounts and a wire inlet guard.
FORM OF RUNNING
Cased fans have arrows showing the direction of impeller rotation and airflow.
For reverse running the unit can be turned through 180 o .
Alternatively, the airflow direction may be reversed by changing over the electrical
connections in the fan, but a drop in performance will result.
