Filtering unit
UFO-A-5000 24.05.2019
At
the moment when the suction
volume capacity evidently drops, and it keeps low level
for a longer time, take out the filters and clean them manually
(
with compressed air
)
.
Additionally, undertake control
when the device
is functioning incorrectly in another way. When
the
cartridge filters are damaged of naturally worn out, replace them for new ones. While repla-
cing, put the filters subsequently on the guide profiles and push them tightly to the wall of the
electro-valves chamber.
Subsequently tighten the filters with a profile straps and screw knobs.
Close tightly the door of the chamber of filters and tighten up the screw locks of the door.
Having replaced the filters connect the device to the power supply again.
Upon
normal functional
wear out,
the cartridge
filters must be replaced after 1 to 2 years of ope-
rational use.
9.2 Fan
After every year
of operational
use
– clean and examine the impeller, the state of the fan motor
itself, according to the instructions of the motor manufacturer. In case of incorrect function of
the fan,
contact
with the manufacturer.
When it is necessary to
replace the
fan or the motor, this
can be executed exclusively by a specialised team.
9.3 Compressed air tank
The
compressed air tank
should
be examined and submit to maintenance
–
according to
the re-
gulations on pressure devices. Periodically, check all the connections applied on the tank, and
make dewatering
through the drainage fitting piece that is installed for
this purpose at the bottom
part of the tank.
9.4 Electromagnetic valves
The applied electromagnetic valves do not require current maintenance. It is sufficient to check
the state of electrical connections, the state of grounding and tightness of the pneumatic instal-
lation. It is recommended
to replace the valves after 2 years of use, but not later than 4 years.
For this purpose contact the manufacturer of the filtering unit.
9.5 Pneumatic silencers
On the
electromagnetic
valves are p
laced pneumatic silencers 3/8” to reduce the noise level du-
during the compressed air “shot”.
After two months of use,
the silencers must be disassembled and cleaned. For control periods
see Table below.
9.6 Suggested periods of control and maintenance of the filtering unit
Table No.4
Current control of the function after the
waste container is filled up.
Empty the container from the deposited dust.
Routine (current) control
Systematically clean the device and assemblies, so
the dust particles would not deposit on the ele-ments.
Upon each emptying of the waste container Check visually the cartridge filters, through the door
of the chamber of filters.
Every 2 months
Clean the pneumatic silencer (located on the electro-
magnetic valve)
– soak in the extraction naphtha and
clean it.
Once a month
Examine the state of the device grounding and check
the conductivity between all the assemblies of the
filtering unit.
Every 2
÷ 3 months
General visual inspection of the supporting structure
and the housing, check the screw connections.
Every 12 months
Examine the state of electrical connections and
the installation of the compressed air, the
connections of the electromagnetic valves.
