NOTES:
�Where an open-flued oil or gas- fuelled
appliance is installed in the kitchen, extract
ventilation can cause the spillage of flue
gases. Care must be taken to ensure
ventilation is reduced as appropriate, as set
out in the building regulations. The guide to
the regulations suggests that the reduced
provision should be an extract rate of 20 l/s
(72 m3/h) maximum. Kitchens with
solid-fuel appliances should not have extract
fans fitted.
�The fans should not be sited where
it would be subject to a direct source
of heat in excess of 40ºC.
�For window mounting do not install fans in
opening windows. Use the correct thickness
of glass for the size of window (at least 4
mm thick) if in doubt, contact a glazier.
�A clearance of 75 mm to be allowed on both
sides of fan for the removal of the internal
grille.
Operation
The Airvac Elite range of fans are single speed
SELV 12V axial flow extract fans to exceed
Building Regulation requirements for bathroom
and toilet ventilation. The remotely mounted
controller contains switch line control.
Types of controls and operation
as follows:
TYPE ‘T’
Operation by pull cord, light switch
or remote switch.
Integral pull cord will activate the fan for
pre-set overrun timer operation.
If wired into room light or remote switch the fan
will operate whilst the switch is on. Switching off
will activate the overrun timer.
TYPE ‘TR’
Operation by light switch or remote switch.
When wired into room light or remote switch the
fan will operate whilst the switch is on. Switching
off will activate the overrun timer.
TYPE ‘HTR’
Automatic operation by light switch or remote
switch.
The fans integral humidity sensor will operate the
fan whilst the RH exceeds the pre-set activation
point, When the RH is reduced back to the
activation point the linked overrun timer
continues to operate the fan for the pre-set time
period to ensure the RH level is further reduced
within the room to prevent ‘hunting’.
When wired into room light or remote switch the
fan will operate whilst the switch is on. Switching
off will activate the overrun timer.
�See Sensor / Timer Adjustments section for further details.
�The Airvac Elite range of fans are fitted with electrical operated anti-backdraught
shutters which have a time delay to open or close.
