5.5. Operation of the self-cleaning system
Models BC126A and BC238A have a self-cleaning system for the lter that can operate at intervals
programmable according to requirements, limiting maintenance to the replacement of the collection
bag.
A timer controls for frequency of daily cleaning of the lter (Figure 3).
Operation of the device is triggered by a compressor that feeds a pressure tank with a capacity of
three liters of air up to a predetermined pressure of 5 bar. At this point an instantaneous air jet is
channelled into the lter through a nozzle. This allows the lter to be kept clean for a longer period.
The lter cleaning parameters pre-set by the manufacturer are as follows:
• 1 daily lter cleaning cycle
• Duration of cleaning cycle 3 minutes
• Start of cleaning cycle at 5 AM
The start time, duration and number of lter cleaning cycles can be varied by changing the timer
settings. The date and time of the timer can also be regulated.
IMPORTANT: During the self-cleaning cycle do not open the dust collector container, and after the
end of the cycle wait at least one minute before opening it
Make annual inspections on the lter to ensure that it is undamaged and to check if it needs
washing (if washed, the lter must be dry before being replaced).
6. MAINTENANCE
6.1. Routine maintenance
Accurate maintenance extends the operational life of the system and ensures constant performance
over time, helping to prevent problems due to unexpected system stop.
ATTENTION: Before proceeding with maintenance operations of any kind whatsoever, unplug the
system from the electrical power supply. Failure to comply with this instruction may expose the
operator to the risk of electric shock.
The intervals between periodic maintenance operations may vary according to the type of use.
Periodic operations Normal frequency
Check lling level of the dust collector bag in the dust container Every month
Check lter cartridge for possible clogging Every month
Cleaning of lter cartridge (models without self-cleaning) Max. every 2 months
Cleaning of lter cartridge (models with self-cleaning) Every year
Replacement of lter cartridge 2 years
