Control box
The controlbox is factory mounted on the hopper according to our standards
(except when specified by order).
If not pre-mounted please make sure that the in-line filter is positioned correctly
on the dirtyside tapping point connection to the control box (refer to figure 12 for
mounting details).
All the instructions related to the controlbox are mentioned in separate manuals.

Compressed air connection
Compressed air pressure must be between 6 and 7 bar.
Be sure that all compressed air components are adequately sized to meet the
maximum system requirementsof 45 Nliters per pulse at max 7 bar supply
pressure (= design pressure).
It is a requirement that adequate precaution is taken to avoid exceeding this
pressure. A relief, safety valve, is required if the connected supply can exceed
this pressure. A label is also attached to each manifold indicating manifold
design details.
Compressed air supply should be both oil and moisture free.
The piping should be installed to provide a fall in the directions of the air flow to
assist in the drainage. A moisture separator should be provided at the lowest
point of the installation.
Purge compressed air supply lines to remove debris before connecting to the
compressed air manifold.
Connect the compressed air supply line to the compressed air connection at
the bottom of the dust collector.
Use thread-sealing tape or pipe sealant on all compressed air connections.
A compressed air shut-off valve, a filter/water separator with automatic
condensate drain, a pressure regulator with gauge must be installed in the
compressed air supply line. Locate these components for convenient service,
in the immediate vicinity of the dust collector.
