Roof Installation
Recommended duct length: 3200 motor — minimum 4 metres, optimal 4-5 metres.
Mount 250mm (ISD) rigid PVC pipe securely to beams, trusses or other appropriate structures: refer figure 1.
The pipe should be mounted vertically with the roof penetration being sealed using a Dektite or other appropriate
sealing membrane or device when installing through a metal finished roof.
DO NOT install on a over lapping join.
Ensure that the PVC pipe protrudes a minimum of 50mm past the top of the Dektite, checking that the fan
assembly clears the roof cladding at upper edge as shown in figure 1 — Roof Mount Option.
Pass power cord and plug through mounting flange and pipe, then out the slotted PVC pipe for connection to the
female plug coming from the canopy/rangehood. Refer to figure 1.
Do not insert plug into socket outlet or switch on until installation has been completed. Fit fan module to pipe and
fix in position using side locking screw.
Certain external installation configurations may cause audible levels of noise to be heard due to the air being
expelled from the motor. To minimize external noise disturbance you can use between 5 to 15 metres of SteelFlex
™
duct to place the Isodrive motor in an appropriate position.
Please be aware that the 3200 motor is capable of expelling air at 3200m

Do not install the SteelFlex
™
in a straight line and minimum of two gentle bends in the ducts is required.
