Assembly, installation and operating instructions
Remedy
Vent heat exchanger.
Set a lower speed, if possible.
Free air ducts.
Replace filter.
Clean and/or replace impeller. Please make sure
that no balancing clips are removed during
cleaning.
Clean dirt from fan.
Clean dirt from Heat exchanger.
Remedy
Switch off, de-energise and remove the mechan-
ical blockage.
Connect the control voltage correctly.
Change potentiometer setting in the motor junc-
tion box.
Check that the airways are clear; remove any
