Installation and Maintenance
Installation
Warning - Units should be installed with the access
panel on the top never upside down.
Installation must be carried out by competent personnel
in accordance with the appropriate authority and
conforming to all statutory and governing regulations.
Units must not be installed at an angle over 5
horizontal (to ensure the backdraught shutters operate
satisfactorily).
Units should always be positioned with sufficient space
to allow removal of the access covers and subsequent
removal of fan and motor assemblies etc.
Ductwork connections must be airtight to prevent loss of
performance.
The method of mounting used is the total responsibility of
the installer. The lower edge of the casing has an internal
skirt allowing the unit to be located on an upstand or
prefabricated curb if desired. The units must be securely
screw fixed to the upstand/curb to prevent vibration
and/or wind damage.
It is the installers responsibility to drill the case to provide
access for the electrical cables. Care should be taken not to
damage internal components and the cable entry must be
properly sealed. NOTE: on bottom inlet units the electrical
cabling may be routed up through the bottom inlet spigot.
Testing after installation
Ensure that the Fan unit and any specified controls are
fitted securely according to the instructions.
Switch on the mains supply. Push the test button to run
each fan and check that they run satisfactorily.

If a switched live signal is used, activate this signal and
check that the fan runs. De-activate the switched live signal
and check the run-on-time; adjust if necessary.
Adjust the set point of any sensors and PIR; check that
they function correctly.
Adjust the maximum and minimum airflow (if required) by
following the commissioning procedures.
