ForallmodelsoftheCSC-3000series,use1/4"(5
mm)O.D.“FR”tubingonthefollowingpush-on
ings:
1. Connecttheclean,dry,oil-freemainairsupplyto
Port“M”(15to30psi).
2. ConnectthedamperactuatortoPort“B.”
3. ConnectthethermostatoutputtoPort“T.”
4. Connectthehigh(“total”)pressuretaponthe
airowsensortoPort“H.”
5. Connectthelow(“static”)pressuretaponthe
airowsensortoPort“L.”
6. Checkforproperconnections.Make sure all
tubes are snug on their ings.Ifloose,trimthe
endofthetubingandreconnectittoensurethere
arenoleaks.
NOTE: Overtime,thetubemaystretchordevelop
microcracks.Trimtheendoftubeback
toundamagedmaterialandreconnect.
Replacethetubingifitisbrileor
discolored.
CAUTION
Pneumatic devices must be supplied with clean,
dry control air. Any other medium (e.g., oil or
moisture contamination) will cause the device
to fail.

Magnehelic gauge and 0–30 psi
gauge in illustration added for
checkout and calibration purposes
CAUTION
To prevent damage to the gauge, do NOT
connect a Magnehelic gauge designed to
measure an air flow sensor’s differential
pressure (e.g., 0–0.5 wc) to the main air
pressure (approximately 20 psi or 554 wc)!
