7.3 MAIN FILTER CLEANING
7.3.1 MANUAL FILTER CLEANING.
IMPORTANT: Lavina V32E is equipped with a signal lamp (fig 3.1 pos.10). The lamp starts
glowing red as the vacuum reaches the red area of the vacuum’s pressure gauge (about -
0.2bar) to indicate that the main filter must be cleaned or changed.
Lavina V32E uses jet pulse manual filter cleaning. One cycle of filter cleaning
takes 10 to 20 seconds, depending on the vacuum’s operator. The filter must
be cleaned as the vacuum gauge goes to red (the LED lamp starts glowing) or
if there’s low suction. If the suction performance is still not improved after a
cleaning cycle is applied, the filter must be replaced with new one.
In fig. 7.3.1 you have the vacuum’s working position on the left. To clean the main filter,
follow the steps below in the exact order:
1
st
. Open the valve situated on the vacuum’s head cover by pushing the lever pos.1 and wait
for a few seconds before releasing. This will discharge the vacuum from the accumulated
dust.
2
nd
. After discharging, close the entrance valve by pushing the lever pos. 2. This creates a
vacuum in the system, indicated by the pressure gauge (fig. 3.1) as it goes to red (-0.28 to -
0.3 bar).
3
rd
. With the system under vacuum, open and close the valve on the head cover pushing the
lever (pos. 1) 3 to 5 times to clean the filter. Allow 1-2 seconds between each valve opening
to build up vacuum in the system again. This can also be verified via the pressure gauge.
Once complete, return to the normal operating position.
