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 e uipment may present mechanical, electrical or noise hazards. To minimize
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 e uipment 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 e uipment 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.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities or lack of experience and knowledge unless they
have been given supervision or instruction concerning use of this appliance by a person
responsible for their safety.
Young children should be supervised to ensure that they do not play with the appliance.
IMPORTANT
1. All electrical connections should be made by a properly ualified electrician. The
fan must be sited and connected in accordance with current I.E.E 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 ade uate 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:-10oC to
+40oC.
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, fre uency, speed, phase
insulation class and IP rating.

3
8. It is the responsibility of the installer to ensure that all aspects of system design
are taken into consideration.
9. Due to the weight of units it is recommended that two people are involved in the
installation.
FAN MOUNTING
1. Short duct runs terminating close to the fan (i.e. within 1.5m) re uire 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 is available from Vent-Axia to assist installation including
flexible connectors, mounting feet, anti-vibration mounts and attenuators.
5. For horizontal installations onto a flat roof or flat ceiling, a fixing bracket is
provided with sizes 100 to 250.
6. If the fixing bracket is used, firstly bolt the bracket to the roof or ceiling. Latch
the ACQ into the 2 x bracket slots, as shown, then rotate and secure with 2 further
bolts (Fig. 1).
7. Tighten all bolts.
8. If the fixing bracket cannot be used, 4 x Ø10mm clearance holes are provided for
roof hanger rods.
9. With the larger 315, 400 and 500 fan sizes, parallel fixing brackets are provided
for both sides of the unit (Fig. 2), and because of the additional weight of these
sizes, extra fixing holes are provided for additional hanger rods.

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 ualified electrician.
2. All wiring and connections must be carried out in accordance with current
regulations.
3. To comply with safety standards, an all pole isolator switch with a contact gap of
at least 3mm must be fitted adjacent to the fan.
4. Remove the cover from the terminal box to expose the main terminal block and
the thermal protection block (TK). 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 re uired, an ancillary circuit will be re uired with the
TK switch connected into the circuit. See page 6 for instructions.
5. Connect the power supply from the local isolator (via any appropriate controls if
fitted) to the terminal box via the supplied cable gland using between 4.0mm and
7.0mm diameter cable. 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. CAUTION: In order to avoid a hazard due to inadvertent resetting of the thermal
cut-out, this appliance must not be supplied through an external switching device,
such as a timer, or connected to a circuit that is regularly switched on and off by
the utility.
7. Ensure that all earth connections have been made.
8. 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
B for Conn cting th pow r supply and running th Fan Ch ck…
Are all links and wiring complete as per wiring diagram?
Are all fixings secured?
Are all relevant guards fitted?
Are all Circuit protection devices fitted?
Are all Terminal box covers and sealing glands secured?
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. Check that the current (amps) taken by
the fan does not exceed the current shown on the rating plate.
INSTALLER AND ELECTRICAL CONTRACTOR RESPONSIBILITY
Vent-Axia Ltd, as suppliers of the e uipment cannot be responsible for the final
installation and electrical connection of the product on site. We have made reasonable
effort to offer guidance and assistance but the installer and electrical contractor on site
have a responsibility for ensuring the e uipment is safely and securely installed and
electrically/mechanically safe in accordance with statutory re uirements.
The fans are supplied as a component to be incorporated into a ventilation system. The
final complete system installation that includes the fans MUST meet the re uirements
of:-
Low voltage Directive 72/23/CEE
Machinery Directive 89/392/CE
Electromagnetic Compatibility Directive 89/336/CE
If the fan is installed in an area where there is possible danger to safety or health then
guards MUST be fitted.
Guards suitable for many applications are available from Vent-Axia Ltd.
Please remember that fans need maintenance, cleaning and inspection. Allow for
reasonable access for these operations to be carried out safely.
If in doubt, please ask.
ROUTINE INSPECTION/MAINTENANCE
THIS MUST BE UNDERTAKEN BY A COMPETENT PERSON.
ISOLATE UNIT FROM ELECTRICAL SUPPLY AND ENSURE THAT IT CANNOT BE
ACCIDENTALLY TURNED BACK ON.
1. We recommend that after three months the fan should be inspected and cleaned
to remove deposits on the impeller or motor. Thereafter, it should be checked and
cleaned periodically as experience dictates, or at least twice a year.
2. If a build-up of dirt/deposits is evident then this should be carefully cleaned off.
Please take care not to damage the fan or affect the balance of the impeller motor
assembly (balance weights may be fitted to the impeller).
3. The fan motors are fitted with ‘sealed for life’ bearings and should not re uire
maintenance under normal circumstances.
