5.4 Fans
The following general steps should be taken to maintain the fans:
•
Check the fan wheel for unbalance (every 3 month).
•
Check the fan and motor bearings for unusual noise (every 3 month).
•
Check vibration dampers for damage (every 3 month)
•
Check the fan for dust or dirt. If necessary, clean the fan wheel, either dry or wet (every
12 month).
•
Check all flexible connections for damage/leakage (every 12 month).
•
Check if all mounting bolts are tight (every 12 month).
•
Check the pressure hoses from the pressure transmitter to the fan for leakage or
damage (every 3 month).
5.5 Filter
If the filters are equipped with a pressure transducer the control panel automatically gives an
alarm when the filters have to be changed. Still every 6 month the filters should be checked
for damage/leakages which will not be detected by the pressure transmitter. If no pressure
transmitter is installed the following steps should be taken every 6 month:
•
Check the filter for dirt and damage.
•
Measure the pressure loss over the filter which should not be below 150 Pa (G3/G4) or
250 Pa (F5/F7). If the pressure loss is higher the filters have to be changed.
•
Open the filter rail by the blue handles (1).
•
Take out the filters (2) and check the gasket on the filter rail for damage.
•
Clean the filter rail and reinstall the old/new filters.
