KMC Controls CSE-1102 Installation Manual

Mounting
Select a mounting location that is free from vibration.
Mount in any vertical plane in order to obtain the
lowest specified operating setpoint. Avoid mounting
with the sample line connections in the "up" posi-
tion. Surface mount via the two 3/16" diameter holes
in the integral mounting bracket. The mounting
holes are 3-7/8" apart.
1. Align the unit vertically with the barbed ports
at the bottom (alternately pointing to the left or
right).
2. Using the two 3/16" mounting holes, attach to the
ducting.
3. Using the knockout, attach a 1/2" conduit.
4. Connect wires to the screw terminals. See the
Wiring section.

NOTE: A sampling probe should be located
NOTE: For sample lines of up to 10 feet, 1/4" OD
To attach a sampling line:
• To a CSE-1102 with barbed connections, use 1/4
• To a CSE-1103 with compression connections,
Connect the sampling lines according to the applica-
tion:
• Positive Pressure Only: Connect the sample line
• Negative Pressure Only: Connect the sample line
• Two Negative Samples: Connect the higher
