Pneumatic Installation
Install a customer-supplied regulator, filter, dryer,
and lock-out bleed-type isolation valve between the
plant air supply and the dust collector manifold to
allow safe and convenient service.
Install the 1 x 1/4 x 1-in reducing tee at the
connection point of the compressed air supply.
Locate this fitting immediately adjacent to the
manifold. See Fitting Installation. On multiple-
module installations, install fitting between the
manifolds.
Pneumatic Installation
The collector has tubing fittings installed in the clean-
and dirty-air chambers. Attach a section of tubing
from the clean-air chamber to the low pressure fitting
on the enclosure. Attach a section of tubing from the
dirty-air chamber to the high pressure fitting.
Connect a section of 1/4-in OD, 120-psi rated tubing
from the collector’s manifold at the point closest to
the hookup of the plant air supply to the compressed
air line pressure tap on the enclosure. An installation
drawing has been shipped with the Checker board
that illustrates proper connections.
