5.2 FILTER CLEANING
LAVINA® V32-X-400-E dust collector has an
automatic filter cleaning cycle system with
adjustable filter cleaning interval. The main
filter cleaning is done by the jet pulse. The
operator can set the time interval for the filter
cleaning with the FILTER CLEANING
INTERVAL potentiometer. The minimum
interval between cleaning is 5 minutes and the
maximum is 50 minutes. To increase the
interval, turn the potentiomer clockwise. Each
division of the potentiometer corresponds to 5
minutes. The cleaning cycle lasts 10 to 12
seconds.
The operator can activate the cleaning
anytime by pushing the FORCED CLEANING
button. While forced cleaning is running, the
button flashes.
If the suction is not good, the cleaning cycle
may be run 4 to 5 times by pressing the
FORCED CLEANING button. If the suction
does not improve after the forced cleaning
and the vacuum gauge (pos.24; fig.1.1) shows
more than 0,25 bar, change the main filter. If
suction remains poor, also change the Hepa
filter.
Always clean the main filter before replacing
the waste bag, when daily work is done or
there is a poor suction. Activate the cleaning
cycle by pushing the FORCED CLEANING
button.
If the automatic cleaning system fails, the
operator can clean the filer manually by
disconnecting the inlet valve from the actuator
and manually open and close the valve. The dust collector is designed with the option to do this with the handle for
manual cleaning.
For manual (emergency) cleaning of the filter follow the procedure:
- dismount the security cover with two bolts (pos.1,2,3;fig.5.2)
- remove the hairpin cotter pin (pos.5) of the handle serving as a front axle of the actuator (pos.4) and remouve the
axle.
- turn the actuator as shown (pos.4).
- mount the axle in the inlet valve (pos.6).
- put the hairpin cotter pin back in the axle (pos.7).
The filter may be manually cleaned by following the following procedure:
-
1) Close the inlet valve
-
2) Wait for five seconds to rise the vacuum and rotate the lever by using for example a screwdriver
оr 1
1/16
wrench (pos.8 fig.5.2)
-
3) Repeat the 2
nd
step five times
-
4) Open the inlet valve and continue working
