PANEL MOUNTED AXIAL
1. The fan is designed to be positioned in a panel or wall aperture.
2. The fan is suitable for mounting at any angle using the corner holes.
3. Ensure the fan impeller rotates freely before and after installation.
4. Plan the installation carefully, taking into consideration the safety points noted above,
before securely fixing the fan using appropriate screws, bolts, rubber bushes, etc.
5. If the fan is mounted less than 2.3m high, an external guard must be fitted. A range of Discharge Guards or
Louvre Shutters are available from the Vent-Axia accessory list.
FORM OF RUNNING
Panel mounted fans (ex-stock) are supplied for extract use (Form 'A' running). When used for intake, the fan can be
wired for reverse running, although performance will be reduced.
GENERAL WIRING INSTRUCTIONS
WARNING – THE FAN AND ANY ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM THE POWER
SUPPLY DURING INSTALLATION AND/OR MAINTENANCE. THE EQUIPMENT MUST BE EARTHED.
1.
All electrical connections should be made by a properly qualified electrician.
2.
All wiring and connections must be carried out in accordance with current regulations.
3.
It is recommended that an all pole isolator switch is fitted adjacent to the fan for safety during
maintenance/servicing.
4.
Remove the cover from the terminal box to expose the main terminal block and the thermal protection block
(TB). The thermal protection device fitted is an automatic resetting type which must always be included in the
circuit. For ducted applications a manual reset is required, an ancillary circuit will be required with the TB switch
connected into the circuit.
5.
Connect the power supply from the local isolator (via any appropriate controls if fitted) to the terminal box via an
appropriate cable gland. Refer to the wiring diagrams and select the appropriate connections for the fan,
controller or other devices as being installed. If in doubt please ask.
6.
Ensure that all earth connections have been made.
7.
After making connections inside the terminal box, replace the cover ensuring that the sealing gasket is in place.
Also ensure that all cable gland nuts, grommets etc. have been used correctly to prevent the ingress of water.
NOTES ON RUNNING
Before Connecting the power supply and running the Fan Check...
Are all links and wiring complete as per wiring diagram?.
Are all fixings secure?.
Are all relevant guards fitted?.
Are all Circuit protection devices fitted?.
Are all Terminal box covers and sealing glands secure?
Are all Earth connections secured?
Check that no hazard exists for persons in the locality of the fan. Switch on the fan and check that the fan
rotation is correct as per the direction arrows on the fan plate/casing. If not isolate power supply and
check wiring. For three phase fans interchange of any two phase leads on the supply will change rotation.
Check that the current (amps) taken by the fan does not exceed the current shown on the rating plate.
