Please ensure that if your butterfly valves are fitted, that the tape stuck over your butterfly valves in the factory
is removed when your unit is installed. Failure to remove the tape on the two butterfly valves will result in
airflow outlet to be restricted and this will cause the air to be returned causing the blowing of air instead of the
extraction of air. Before booking a service call make sure you check this first to avoid being charged.
(a)This is a picture of the butterfly valve closed with the tape on top:
The tape should be removed when installed. Both butterfly valves open when the extractor is switched on:
(b) Ducting hoses exceeding the 2.5meters will also have a negative effect on the extraction rate of your extractor fan.
If you are out-venting the air and the extension of ducting hose exceeds 2.5meter you need to purchase an addition
extraction motor that must be installed in line with the ducting hose to support in the extraction of the air. The longer
your ducting hose the less your extraction rate will be. If your ducting hose is too long and you did not install an
additional extracting motor in line with the ducting hose, your extractor will not extract the air. Please ask your installer
about an additional inline motor when your ducting hose is exceeding 2.5m.
