When a console with a dirty filter indicator is selected, the remote console
includes a fourth light (dirty filter indicator light). The light is activated by an
adjustable, single-pole/normally open differential pressure switch that senses
air pressure across the filter bank. There are field-installation procedures that
must be done for the proper operation of the dirty filter indicator light.

Installation Instructions
o
Before the system is operating, connect the sensing tubes from the
switch to their sensing locations in the field-installed filter cabinet. (Cabi-
net installation instructions are in Paragraph 15.)
1) Run the tubes through the holes in the cabinet wall. Pull gently to
extend the tubing to its entire length without stress.
2) Position the tubing approximately at the center of the height of the filter
rack.
3) Identify the tube connected to the positive connection on the switch
(FIGURE 11) as the positive pressure tube. Determine the length of
tubing required to attach the positive pressure tube so that it will sense
pressure at the inlet side of the filter rack.
Identify the tube connected to the negative connection on the switch (FIG-
URE 11) as the negative pressure tube. Determine the length of tubing
required to attach the negative pressure tube so that it will sense the
pressure at the blower side of the filter rack.
(NOTE: Tubing shipped is the same length for all sizes of systems; cut to
the appropriate length for the smaller systems.)
4) If required, cut the tubing to the proper lengths. Using the clamps
provided, attach the ends of the tubing to the filter rack at about center
height being careful not to kink or compress the tubing.
o
After the system is operating, the filter switch must be manually set.
With clean filters in place, blower doors closed, and blower in operation,
increase the pressure setting by adjusting the set screw on the switch
