FIELD ADJUSTMENT
The adjustment range of an AFS-460 Air
Switch is 0.4" ± 0.06" w.c. to 12.0" w.c. To
adjust the set point, turn the adjusting screw
counterclockwise until motion has stopped.
Next, turn the adjusting screw four complete
turns in a clockwise direction to engage the
spring. From this point, the next ten turns will
be used for the actual calibration. Each full
turn represents approximately 1.16" w.c.
Please note: To properly calibrate an air
switch, a digital manometer or other mea-
suring device should be used to confirm the
actual set point.
