Installation

Preparation

Plan the installation beforehand to ensure that the best possible ventilation solution is achieved.
Lay out fans, intake grilles, branches and ducts in the roof cavity making sure that suitable suspension points for 
the fans and intake grilles are available.

Ducting

-  Make sure there is at least 2m of duct between the fan and the first bend or branch of which the first metre    
 

from the fan must be straight.

-  Keep ducting paths as short and as straight as possible (ducts can be cut or extended).
-  Take appropriate safety measures when cutting hazardous building materials.
-  Cut a hole in the soffit and install the make-up air grille.
-  Cut holes for the diffusers using the cardboard templates provided.
-  Tape ducts to diffusers and install diffusers.
-  Pull ducts taught, cut off excess and tape to branches, fans and grilles.
-  Make sure the inner and outer sleeve of the acoustic duct is taped thoroughly so air cannot leak out.
-  Wind duct tape 3 times around duct and spigots for a secure connection. 

DO NOT

 put excessive strain on taped connections.

-  Suspend the fan no more than 400mm above the roof insulation and ensure it does not make direct contact    
 

with any framing.

-  Secure the intake grille to ensure the system cannot suck up the roof insulation.
-  All electrical/electronic and mechanical parts must be installed and all ducting secured before applying mains  
 power
-  The system can be extended to a total duct length of 24 metres.

Diffusers

-  Install diffusers in living spaces to be heated (e.g. bedrooms and living rooms). 
-  Where possible, install diffusers within 2m of windows and keep away from doorways.

DO NOT

 install diffusers in wet areas (e.g. bathrooms, kitchens and laundries).

DO NOT

 install diffusers within 1m of smoke alarms and walls, or security sensors and walls.

DO NOT

 install near the doorway.

-  Use the cardboard template supplied to cut the hole for the diffuser. 
-  Before fitting the diffuser make sure the spring loaded arms are pushed upwards, as this will enable the arms  
 

to spring outwards when the diffuser is inserted in the hole.

-  Regulate the amount of warmed air to each room by turning the diffuser cone clockwise to decrease the  

 

 

airflow or anticlockwise to increase the airflow.

 

-  Set the touch screen controller up before use (refer to Installation: Touch Screen Controller, page 8).
