ASSEMBLY AND STARTUP
6.1 Description of mounting
Before the assembly of the device in the place of use, check if the device is complete, and if it is not damaged, or
there are indentations, etc. The appliance is delivered in two assemblies, so it should be installed by means of
adequate lifting devices and by a specialised assembly team.
First, put the supporting structure with the hopper chamber. The supporting frame should be levelled and its legs
fastened firmly to the floor. Having installed the first assembly, put the chamber of filters (with the fixed to it
regeneration chamber) on it. Handle with care, as the assembly is of large dimensions. At the upper part of the
regeneration chamber are installed lifting hooks (for lifting and positioning during the transport and assembly
activities).
After the chamber of filters is connected with the supporting structure, seal up the join surface
with “silicone” and
screw it up thoroughly with bolts. The screws, bolts and “silicone” are delivered by manufacturer along with the
device.
The compressed air tank and the electromagnetic valves are delivered to the operator in completely assembled
state. Having installed the device, connect it to the external compressed air installation of 0,6
0,8 MPa. The
pressure air must not contain pollutants, oil and humidity.
The connection must be equipped with a cut-off valve, air filter and a dewaterer. These elements are not
delivered along with the device.
The nominal diameter of the compressed air connection (for the device of 9 cartridge filters and at the nominal
diameter of the compress
ed air tank of 8”) should be 1”1/2.
6.2 Start-up
Upon first operation of the compressed air installation (of the device), check if the connected part of the
compressed air system is sufficiently cleaned of the metal particles, rust, etc., because the membrane of the ele-
ctromagnetic valves would get damaged. If in the first stage of start-up there is not enough air flow intensity (in
the system)
– this means the valves are not tight enough. Shut the cut-off valve in the supply of the compressed
air tank. Wait until the air pressure in the system reaches 0,6
0,8 MPa, and then quickly open the cut-off valve.
The fan chamber with the Ex fan inside
– is located on top of the filtering unit – see Fig. No.3.
Connect the electrical system, power supply and the control units
– strictly according to the enclosed Connection
Diagram Fig. No.7, 8 and 9. As the control system is very complicated, any activity of device connection/energizing
must be carried out by an authorised installing team with qualifications. The filtering unit and the fan should be
connected to the equilibrating grounding profile.
Connect the motor with reference to the adequate data placed on the nominal data plate and in conformity with
the Connection Diagram on the cover of the terminal box (fastened to the motor).
Switchgear A1 should be mounted in area, beyond the explosion hazard zone
.
6.3 ATEX Directive
BIG-10000/Ex filtering unit has been classified, according to the 2014/34/Ex Directive and therefore, it is
important to take precaution measures during the installing and start-up, and follow subsequent aspects:
As the filtering unit is of Category 3D, it should be installed according to the PN-EN 60079-0:2013,
PN-EN 1127-1:2011, PN-EN 13463-1:2010 standards, therefore the installer must be thoroughly ac-
quainted with the contents of these standards
