2.6 Pneumatic Installation
—
Remote Checker Board
(See Figure 9)
The Checker board requires pneumatic
connections. The collector has tubing fittings
installed in the clean air plenum and the dirty air
plenum. Attach an airtight, clear tube from the
bulkhead fitting on the enclosure to the matching
fittings on the SDF. An installation drawing has
been shipped with the Checker board which will
show all of the proper connections.
3.0 PRE-START UP CHECKLIST
• Make sure all connections to both air and
electrical are in the correct position according
to the installation print.
• Recheck all of the electrical and air
connections for tightness and leaks.
• Verify that all electrical systems have been
properly grounded.
• Verify the proper installation of the
collector(s) for which the Checker board has
been installed.
• Verify proper blower rotation by pushing the
start-stop button on and off very quickly. The
rotation should be clockwise when looking
down on the top of the motor (Torit blowers
only). See Section 4.0 Start Up/Calibration for
blower rotation fault light.
