Installation and Wiring Instructions
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.
The Fan should be provided with a local isolator switch
capable of disconnecting all poles, having a contact
separation of at least 3mm.
Ensure that the mains supply (Voltage, Frequency, and
Phase) complies with the rating label.
The Fan should only be used in conjunction with the
appropriate Airtech products.
The fan should only be used in conjunction with fixed wiring.
When the Fan is used to remove air from a room containing a
fuel-burning appliance, ensure that the air replacement is
adequate for both the fan and the fuel-burning appliance.
The Fan should not be used where it is liable to be subject to
direct water spray for prolonged periods of time.
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.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental

SAFETY AND GUIDANCE NOTES

DESCRIPTION
Radon mitigation fans are used with under-floor extract and ventilation systems designed to
remove the gas from underneath the floor of a house and vent it into the atmosphere through
a pipe.
Radon is measured in becquerels per cubic metre of air (Bq m3) and Public Health England
(PHE) has set the UK Action Level for radon at 200 Bq m3. Most homes in the UK have radon
of around 20 Bq m3. Above 500 Bq3 a radon sump fan installation is usually required.
The UT150/SC is a centrifugal fan which can be used for becquerel levels from 0 to 2000+.
The UT150/SC is supplied with a Single Phase SC (Electronic) - 1.5 amps controller, an
infinitely variable speed controller that allows you to manually adjust the speed of the fan by
varying the motor voltage through phase angle control.
SITING
Avoid installing the fan on an occupied bedroom wall if running the fan at high speeds.
It is normal for the fan to be set at the mid point on the controller for levels of approx. 200 plus
Bqs up to 1500Bqs. The lower and higher settings are generally for use after a re-test or if the
levels are exceptionally high.
Please note the supply voltage can affect the speed of the extraction rate.
All connections must be via
fixed wiring. The speed controller is
supplied fitted inside a IP67
rated enclosure.
Use the supplied brackets to mount
the fan to the wall.
Ensure the fan is the correct way up
(note the airflow direction arrow on the fan)
IMPORTANT: After installation, the fan wiring enclosure should be sealed with silicone
sealant to ensure water cannot get in and damage the fan.
