INSTALLING THE SYSTEM
Before commencing installation, select a suitable place for the fan to be installed in the
ceiling cavity. It is recommended to place the fan and filter near the manhole for easy access
when carrying out maintenance to the system. Suspend the fan and filter from the ceiling
framing with the chain and cable ties provided in order to minimise the sound levels
resonating through the ceiling framing.
If the system will be taking air from outside or the fan or air inlet is installed in outside
windows or walls, care must be taken to avoid the backflow of gases into the system from
open gas flues or other open-fire appliances.
Attach the inlet side of the fan to the filter frame using the duct tape provided. Connect the
acoustic ducting to the outlet of the fan. The acoustic ducting should be 1-1.5m long and
placed after the fan to eliminate sounds from the fan motor inside the ducting system.
The inlet of the fan unit is the end where you can see the fan blade clearly. There are also
arrows on the unit showing airflow direction.
Spending time planning the layout of the ducting system is important. See the inside page
of this instruction manual for further details and example layouts.
Some simple rules to apply to ensure the best possible results:
• Lay the ducting so there is a roughly equal length of ducting to each diffuser.
• The shortest length of ducting should be no shorter than 3 metres.
• Avoid tight bends in the ducting.
• Ensure the ducting is stretched out fully. Cut the ducting if needed.
• Avoid installing the ducting where it may be crushed or damaged by you or other tradesmen.
• Avoid installing the diffusers near doors/hallways and directly above beds or couches.
If a wall controller is included with the system, this is connected to the fan via the supplied
network cable. The controller is low-voltage only, however to prevent any damage to both
the fan and controller, please ensure that the fan is disconnected from the mains supply
before connecting the controller.
STARTING UP THE FAN
Before starting up the fan, ensure that:
• The apparatus is well secured and the electrical connections have been carried out correctly.
• Any electrical safety devices are correctly connected, adequately adjusted and ready for use.
• The wire and electrical connection inputs are correctly sealed and water-tight.
When starting up the fan, ensure that:
• The propeller turns in the correct direction.
• There are no abnormal vibrations.
If the circuit protection device is tripping during operation, the apparatus must be quickly
disconnected from the mains supply. The whole installation should be carefully checked
before trying to start up the machine again.
When the fan is first powered up, there may be a momentary startup delay of up to 30
second while the fan is calibrating the sensors or checking user input from the wall
controller.
