been checked and the problem persists, Contact your local

1. Remove obstructions from the outlet opening(s) and/or
connected ductwork.
2. Replace lter cartridge.
3. Install non- return valve(s) correctly.
1.Press alarm reset and investigate VFD fault issue. Note the
VFD has an LCD display that will assist troubleshooting with a
message or fault code to help determine reason for the fault.
2. If the Differential Pressure read by the sensor is higher than
your DP Alarm set point your alarm light will be on and
ashing and the unit most likely has already passed your
online cleaning set point (default of which is 1500 Pa). Filters
need to be changed if this DP reading is correct and your set
point is realistic.
Check fuses for incoming power to the drive and for the
controls power and replace if necessary.
Remove and re-apply AC line voltage to the unit after a 1
minute delay. Variable Speed Drive will reset for some faults. If
this cycle repeats locate the source of fault- checking motor,
wiring and each connection point to motor and the VSS.
Replace VFD if determined to be faulty.
After checking for proper 24VDC supply to devices. They
should each have a green power "POW" light on. Determine
normal lights seen on an operating unit if possible and
compare to the faulty controls for hints on what component
isn't operating correctly. Replace suspected component(s).
