Fan adjustment—Timer
The fan with timer function switches on when the voltage
is supplied to the LT or L1 terminal via an external switch.
After the voltage to the LT or L1 terminal is disconnected
the fan continues to run for the set overrun period,
between 1 and 20 minutes. The timer overrun is factory
set to 15 mins, it is adjusted by turning the potentiometer
(T) clockwise to increase and anti-clockwise to decrease.

Installation with flexible ducting
Where flexible ducting is used the diameter must be
maintained with the minimum radius of a bend equal to the
diameter of the ducting. It is good ventilation practice that
the ducting is extended to 90% of its possible length in
order to maintain the best possible airflow. Ensure that
flexible duct connections are not over tightened to the fan
outlet spigot. To maximise airflow rigid ducting should be
used where possible. The fan and ducting should be
installed in accordance with the requirements of the
Domestic Ventilation Compliance Guide, part of the
Building Regulations.

Recommended Best Practice
The Building Regulations 2010, Statutory Instrument Part
9, paragraph 42, imposes a requirement that testing and
reporting of mechanical ventilation performance is
conducted in accordance with an approved procedure.
Compliance with this requirement by an assessed and
registered 'Competent Person' should follow a 'Best
Practice' process and adopt air flow measurement,
Method A – The Unconditional Method – using a suitable
UKAS certified measuring instrument. Generically referred
to as a 'Zero Pressure Air Flow Meter' or 'Powered Flow
Meter'.
Further information on this method is detailed in NHBC
Building Regulations Guidance Note G272a 10/13 and
BSRIA 'A Guide to Measuring air flow rates' document
BG46/2015
