IMPORTANT

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE COMMENCING INSTALLATION

1. It is recommended that this controller is installed by a qualified electrician.

2. The installation and wiring must comply with current IEE Regulations, BS7671, or the
appropriate standards in your country.

3. This controller is not suitable for use in rooms containing a fixed bath or shower.

4. This equipment MUST be earthed

On receipt of your controller, check that:
a). It is the correct rating for the size of
motor
b). the voltage and frequency are correct.

Location

The controller may be sited in any
convenient position that is unaffected by
direct heat sources such as radiators,
boilers, etc. Do not site the controller
where it may be subject to water spray,
condensation, damp or wet conditions.
Ensure the controller is installed in a
ventilated area. Ensure that the
enclosure is securely mounted using
appropriate fixing screws or bolts.

Fitting

Unscrew the two screws and remove the
lid/switch from the mounting box. The
mounting box may be fixed to most
single or double gang recessed metal
outlet boxes or alternatively fixed direct
to the wall for surface cable entry. When
using surface wiring that is not being
contained in conduit, the supply and
output cables must be securely clipped to
the mounting surface, close to the
controller.

Wiring
WARNING: THIS APPLIANCE MUST
BE EARTHED

Ensure that mains supply is isolated
before proceeding with the wiring. The
installation must be provided with a
double-pole isolator switch, having a
contact separation of not less than 3mm,

and be protected with a 3 amp fuse
(U.K).

If using automatic control via electro­mechanical ON/OFF switched sensor e.g
electro-mechanical thermostat, timer,
relay etc. ensure sensor switch is
adequately rated for the switched load.
After making wiring connections, check
that they are all correct and secure,
replace lid.

NOTES ON RUNNING

Before switching on CHECK:
Control unit and motor/fan are secure
Earth connections have been made and
are secure
Switch on mains
Slide control to maximum and down to
minimum to ensure motor/fan operates
accordingly.

MINIMUM SPEED

The control unit has been factory set to
Vent-Axia’s recommended minimum
speed.
A minimum speed adjuster is located on
the front of the controller and is exposed
when the bottom slide bar is moved fully
to the left. This adjuster is used to vary
the lowest speed setting if the fan does
not revolve when the controller is set to
minimum speed.
Using a small screwdriver, turn the
adjuster clockwise to increase the
minimum speed setting.
After any adjustment, make sure the fan
will start from a stationary condition by
using the ON/OFF switch with the
variable speed slide knob set6 fully to the
left (minimum speed).
