One cleaning cycle consists of six compressed air pulses.
Automatically | at fan shutdown
After ≥30 minutes of (intermittent or continuous) operation,
one cleaning cycle takes place when the fan is off, with a delay
time of 15 seconds. If the fan starts running again within
those 15 seconds, the filter cleaning system will not be
activated.
Automatically | pressure controlled
A differential pressure switch activates the filter cleaning
system immediately when the pressure drop reaches the
threshold value during use.
Manually | by push button
To activate the filter cleaning system manually, do the
following:
• Push and hold the FILTER CLEANING button (ref. Fig. 5.1D)
for 5 seconds.
