Operation of the filtering cartridges

1.
Electropneumatic device
2. Filter cartridges
3. Timer
The filtering cartridges (2) serve the purpose of filtering
the intake air. The vacuum cleaner is equipped with a fully
automatic electropneumatic device (1) to alternately clean
the filtering cartridges (2), which guarantees continuous
service.
Powered with a 24V rating, is complete with cyclic timer (3)
to regulate the following times:
T3= time between one cleaning cycle and the next, set on 0
seconds;
T2= time between one cleaning operation of the cartridge
(2) and the next, set on 20 seconds;
T1= opening time of the solenoid valve for backwashed air
exhaust into the cartridge, set at 2 ÷ 3 tenths of a
second. The shorter the time, the more energetic the
cleaning action will be.
Check the arrows on the knobs of the timer (3) for the
exact regulation.
The factory settings must not be modified without
prior consent from Blastrac.
The three solenoid valves of the electropneumatic device
control the cleaning of the relative filter cartridges.
1. Filter cleaning solenoid valve E1
2. Filter cleaning solenoid valve E2
3. Filter cleaning solenoid valve E3

Maintenance, cleaning and
decontamination
WARNING!
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the filter.
■ To allow the user to carry out the maintenance
operations, the vacuum cleaner must be
disassembled, cleaned and overhauled as far as
is reasonably possible, without causing hazards
for the maintenance staff or other people. The
suitable precautions include decontamination
before disassembling the device, adequate
filtered ventilation of the exhaust air from the
room in which it is disassembled, cleaning of
the maintenance area and suitable personal
protection.
Compartments that are not dust-tight must
be opened with suitable tools (screwdrivers,
wrenches, etc.) and thoroughly cleaned.
■ Carry out a technical inspection at least once
a year, for example: check the filters to find
out whether the air-tightness of the vacuum
cleaner has been impaired in any way and
make sure that the electric control panel
operates correctly. This inspection must
be carried out by the manufacturer or by a
competent person.

Filter disassembly and replacement

WARNING!
When the vacuum cleaner is used to vacuum
hazardous substances, the filters become
contaminated, therefore:
■ Work with care and avoid spilling the
vacuumed dust and/or material.
■ Place the disassembled and/or replaced filters
in a sealed plastic bag.
Close it hermetically.
■
■ Dispose of the filters in accordance with the
laws in force.
WARNING!
Filter replacement is a serious matter. The filters
must be replaced with ones of identical filtering
surface characteristics.
Otherwise the vacuum cleaner will not operate
correctly.
