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 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
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.
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
qualified 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 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:-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,
frequency, speed, phase insulation class and IP rating.
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) require suitable guards.
2. All ATQ units MUST be installed in a horizontal position.
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 parallel fixing brackets are provided for both sides of the unit
(Pic. 1),and extra fixing holes are provided for additional hanger rods.

6. All twin units have a pair of exit airflow gravity shutters fitted which must be orientated
correctly to match the floor or ceiling mounting chosen for the installation. As supplied from
the factory, the gravity shutters are correctly fitted for floor mounting the unit. If the unit is
to be ceiling mounted, the shutter assembly must be repositioned as (Pic. 2.). To do this,
remove the top cover to gain access to the outlet plenum area. Remove the 6 x M6 screws
holding the shutter assembly in place then detach the assembly and rotate through 180
degrees. Then refit the assembly using the 6 x M6 screws ensuring that the foam sealing
strips remain fitted correctly.

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. 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 required, an ancillary circuit will be required 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
Before Connecting the power supply and running the Fan Check…
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 equipment 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 equipment is safely and securely installed and electrically/mechanically safe in accordance
with statutory requirements.
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 requirements of:-
Low voltage Directive - 2014/35/EU
Machinery Directive - 2006/42/EC
Electromagnetic Compatibility Directive - 2014/30/EU
If the fan is installed in an area where there is possible danger to safety or health then guards
MUST be fitted.

6
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 require maintenance
under normal circumstances.
Wiring Diagrams:
Important Notes:-
•For ducted applications the Thermal Protector (TK) must be connected into a control
circuit in order to ensure that the fan cannot restart before the fault condition is cleared
and the circuit manually reset.
•To comply with the above statement, this product is intended for use with Vent-Axia
