To avoid the back flow of condensation into the fan in the
ceiling installations it is good practice to fit a condensation

Where flexible ducting is used the diameter must be
maintained and 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 avoid reduced air flow rigid ducting should be used
(see airflow.com). The fan and ducting should be installed
in accordance with the requirements of the Domestic
Ventilation Compliance Guide, part of the
Building Regulations.

Pre-Start
Phase
Automatic Humidity Control with a progressive increase in
humidity—the fan will boost when the pre-set value (factory
setting 70-80% RH) is reached. However, when the sensor
detects a rapid increase in humidity the fan will boost
automatically before the pre-set value has been reached so
that preventive ventilation commences. The fan reverts to
trickle automatically when the humidity is reduced to 10%
below the set point. Note: It is possible that a high level
of humidity is present within the room for a longer period
of time due to generally high humidity in the ambient air
(summertime) or a build up of high humidity over several
hours (steam rooms/sauna etc.)
