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.

INSTALLATION

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.
