When the differential set point is reached, both the audible
and visual alarms will be triggered and will remain engaged
until both the Alarm condition is corrected, and the Alarm-
Reset button is pressed. (If the Alarm-Reset button is pressed
but the differential pressure is beyond the set point, the
alarms will re-engage immediately).
After the strainer is cleaned and put back in service, the
differential pressure should return to 1 PSI.
If you have any questions about the Pressure Differential
Alarm option, please call our technical product specialists at

General Information
Auxiliary Contacts:
The PDA option is equipped with a remote alarm feature.
The remote alarm contacts are located at the two Black &
Red Banana Clip Posts (see illustration). The alarm can be
set up in one of two ways: 1) a remote alarm signal of 12
VDC can be sent to a central monitoring station, or, 2) a set
of auxiliary contacts will indicate a "closed" condition when
the alarm activates. (See auxiliary Contact Schematic inside
PDA Box). Remove the (4) screws on the cover plate and to
access the schematic located inside the cover plate.) If you
have any additional questions please contact a ClimaCool
technical representative at (405) 745-3185.
Water Resistance:
The Pressure Differential Alarm Controller is water-resistant,
but not water proof. Do not install below ground level where
the box can be submerged in water. DO NOT REMOVE the
cover plate from the PDA Controller. Keep the cover tightly
sealed on the module during normal operation.
