7.5 Operation
Operation is identical to a standard system, with the exception of the automatic filter cleaning function.
For the Vibra-Pulse cleaning, this takes place automatically ten minutes after the fan stops and requires
thirty seconds to complete. If either of these conditions is not satisfied, cleaning either does not start or
is aborted. A manual “re-clean” pushbutton is provided which causes another 30-second cleaning cycle
to be initiated when the button is pressed and released, but only if the ten-minute time-out period has
expired.
Multiple sequenced solenoid cleaning is similar, except that there is no delay after fan stop. A red
“CLEANING ON” indicator indicates when cleaning is in operation. Additionally, a contact is brought out
to be used by an air make-up system of for any other purpose as required. There is also a MANUAL
CLEAN override switch which triggers cleaning regardless of any other condition. This should be used
with caution.
7.6 Troubleshooting
This is again similar to a standard system, with the exception that the sequencer or timer relays may also
fail. Such a failure would be immediately obvious, and would require replacement of the sequencer or
affected relay.
