there is a brief description of the optional electrical controls used for airow. Refer to
the operation manual, Form O-ADF/RDF, for additional control information.
Remote Console
If ordered, the optional remote console is shipped separately. Remote consoles include
terminal blocks for wiring. Depending on what gas control or inlet air options were
ordered, the console could include a temperature selector and/or a potentiometer. If
a dirty lter switch is ordered the indicator light is on the console. See FIGURE 15 for
console size.
When a console with a dirty lter indicator is selected, the remote console includes a
fourth light (dirty lter indicator light). The light is activated by an adjustable, single-
pole/normally open differential pressure switch that senses air pressure across the
lter bank. There are eld-installation procedures that must be done for the proper
operation of the dirty lter indicator light.
Dirty Filter Light Installation Instructions
Before the system is operating, connect the sensing tubes from the switch
to their sensing locations in the eld-installed lter cabinet. (Cabinet installation
instructions are in Paragraph 6.2.)
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 lter rack.
3) Identify the tube connected to the positive connection on the switch (FIGURE
17) 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 lter rack.
Identify the tube connected to the negative connection on the switch (FIGURE
17) as the negative pressure tube. Determine the length of tubing required to
