requires minimal maintenance.
The attic space should be inspected visually one to two times per year to check the function of the
system. Fans should be checked and cleaned as necessary, however, at least 1 time/year. This is to
prevent imbalance that can result in unnecessary bearing damage. Servicing is performed according
to the following instructions:
Note that the fan must be disconnected from power before it is opened.
1.
Disconnect the fan from power (all-pole break) by removing the fan connector
in the control unit, and wait until the fan wheel has stopped.
2.
Open the cover.
3.
Clean the inside of the fan but be careful not to deform the fan wheel or upset
its balance weights. Do not spray water inside the fan wheel.
4.
Check that the fan wheel is not obstructed and can rotate freely without
making any strange noises.
5.
Close the cover and reconnect the connector.
6.
Test operate the entire system and perform checks according to section:
