Installation and Wiring Instructions for the ACM IN-LINE MIXED FLOW FAN range.
IMPORTANT: READ THESE INSTRUCTIONS
BEFORE COMMENCING THE INSTALLATION
DO NOT install this product in areas where the following may
be present or occur:
•Excessive oil or a grease laden atmosphere.
•Corrosive or flammable gases, liquids or vapours.
• Ambient temperatures higher than 40°C or less than –5°C.
• Possible obstructions which would hinder the access or
removal of the Fan.
•Sudden ductwork bends or transformations close to the Fan.
SAFETY AND GUIDANCE NOTES
A. All wiring to be in accordance with the current I.E.E.
Regulations, or the appropriate standards of your country
and MUST be installed by a suitably qualified person.
B.The Fan should be provided with a local double pole isolator
switch having a contact separation of at least 3mm.
C.Ensure that the mains supply (Voltage, Frequency, and
Phase) complies with the rating label.
D.The Fan should only be used in conjunction with the
appropriate Vent-Axia products.
E.It is recommended that the connection to the fan connecter
terminals is made with flexible cable.
F.When the Fan is used to remove air from a room containing a
fuel-burning appliance, precautions must be taken to avoid
back-flow of gases into the room from the open flue of gas or
other appliance. Ensure that the air replacement is adequate
for both the fan and the fuel-burning appliance.
G. The Fan should not be used where it is liable to be subject to
direct water spray for prolonged periods of time.

H.Where ducted Fans are used to handle moisture-laden air, a
condensation trap should be fitted. Horizontal ducts should
be arranged to slope slightly downwards away from the Fan.
I. 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
the appliance by a person responsible for their safety.
J. Young children should be supervised to ensure that they do
not play with the appliance.
A. INSTALLATION.
The unit is designed as an in-line duct fan to be positioned between lengths of ducting. Short duct runs terminating close to the
fan (i.e. within 1.5m) must incorporate suitable guards unless the fan is mounted higher than 2.1m above the floor. If flexible
ducting is used it should be fully extended to obtain the best results. Position the fan at the highest point on the system with both
ducting runs sloping downwards from this point. The airflow direction is indicated on the rating label with an arrow pointing in the
direction of the airflow. In circumstances where an excessive amount of moisture is present in the air then a condensation trap
should be installed. (Refer to Fig 15 for overall fan dimensions and fixing hole positions). When siting the appliance ensure that
there is sufficient space to allow access for any servicing and maintenance.
To gain access to the mounting holes, proceed as follows: -
A. Using a cross-headed screwdriver, release the two blue plastic clips by undoing the two bolts as shown in Fig 1. Slide
out motor impeller assembly, see Fig 2.
B. The fan can now be mounted at any angle, using the holes provided Fig 3,4,5,6 & 15
C. Once the base is securely fixed, slide the motor impeller assembly back, as shown in Fig 7. Replace the screw and
tighten to lock the assembly together Fig 8.

B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM
THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
THE ACM FANS ARE DOUBLE INSULATED AND CARRY A MARK. THERE ARE NO EARTH TERMINALS
AND THESE FANS MUST NOT BE EARTHED.
1. Remove terminal box cover & screws and put to one side Fig. 9
2. Select and follow the appropriate wiring diagram (Fig. 10-11).
3. Check all connections have been made correctly and ensure all terminal connections and cable clamps are
securely fastened. (Fig 12)
4. The cable entry must be made using the cable grommet provided
5. Replace terminal box cover & screws Fig.13
6. Ensure the impeller rotates and is free from obstructions
(Timer models cannot be used with a speed controller)
Timer Adjustment.
The fan must be wired to a remote switch (e.g. light switch).
When switched ‘ON’, the fan will operate at the selected
speed, and will continue to run for a preset time after the fan
is switched ‘OFF’. The timer is factory set at 15 minutes
approx. The overrun time period can be adjusted from 3-25
minutes by altering the adjuster on the control PCB with the
use of a small flat bladed screwdriver. Fig 13
Before adjusting the timer, switch off the Mains Supply.
Remove the fan terminal box cover and retain screws
To INCREASE the operating time, turn the adjuster CLOCKWISE.
To REDUCE the operating time, turn the adjuster ANTI-CLOCKWISE.
Replace the fan terminal box cover.

Speed adjustment jumper
Speed Adjustment
The fan has three speeds which are selectable by changing the position of the jumper. The fan is factory set to
Setting 3 - High speed. To change the speed setting, pull the jumper off the header pins and place back onto the
desired position, see Fig14.
Setting 1 is LOW SPEED
Setting 2 is MEDIUM SPEED
Setting 3 is HIGH SPEED
Variable Speed Controller
Speed adjustment for the basic version can also be achieved with the use of a speed controller (stock reference
W300310). If a speed controller is used then the speed setting on the fan unit should be setting 3 – High Speed.
Follow the Installation and wiring instructions for the speed controller unit to install the controller correctly. A
variable speed controller should NOT be used with the timer version.
C. OVER-HEATING PROTECTION.
The fan motor is fitted with Thermal Overload Protection. This is a one-shot thermal fuse. In the event of a fault
condition the fan will be automatically switched off. If this occurs isolate the fan, and call your service engineer.
D. SERVICING AND MAINTENANCE.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to ensure there is no build
up of dirt or other deposits.
The ACM In-Line Mixed Flow fan has sealed for life bearings, which do not require lubrication.
