7. STARTUP
1. Check all hardware to make sure it is tight, and all duct connections
are sealed properly.
2. Check that filters are installed properly and that all lift rails are in
up position.
3. Check that compressed air is on and regulated to 80 PSI
(Recommend using a minimum of 1 in. diameter pipe to plumb the
compressed air to the CMAXX).
4. Check that timer controller is on and properly programmed. See
section 6 for programming instructions. The following settings work
well in most applications.
• Last output: This number needs to match number of
diaphragm valves on CMAXX.
• Time Off: 10 Seconds.
• Time On: 150 Milliseconds.
• High Limit: 3.0 INWC.
• Low Limit: 2 INWC.
• High Alarm: 6.0 INWC.
• Low Alarm: 0.0 INWC.
• Cycle Delay: 0 Minutes.
• Down Time Cycles: 5 Minutes.
• Auto Alarm Reset: 5 Seconds.
5. Set timer controller to continuous and verify that diaphragm valves
pulse properly. You should hear a short pulse of air every 10 seconds in
the dust collector.
6. Set timer controller to on demand for normal operation.
7. Verify that pressure ports on body of CMAXX are plumbed to timer
controller.
8. If using a drum kit with slide gate, make sure slide gate is open and
drum is connected and sealed. Hopper on CMAXX is not intended to
store material in it.
9. Set fan outlet damper to 75% open.
10. Bump start fan and verify wheel is rotating in proper direction.
11. Start fan and allow to reach full operating speed. Check AMP draw.
Fan should be operating below full load amp rating on motor name
plate. If operating above full load amps, gradually close fan outlet
damper until amps drop below full load amps value.
12. It is recommended that air readings are taken at startup and the
fan outlet damper adjusted to match rated CFM of your dust collector.
A dust collector operating above the design CFM will experience
reduced filter life.
