PRIME ERROR may be displayed.
The pump motor is running but with loud noise.
Foreign matter (gravel, metal, etc.) in pump impeller.
Cavitation.
Improper automation IntelliFlo setup.
Communication network inoperative.
Corrective Action
Check trap basket; if plugged, turn pump off and
clean basket.
Check and clean pool filter.
Increase piping size.
Increase filtration run time
Check voltage at motor terminals and at panel while
pump is running. If low, see wiring instructions or
consult power company.
Check for loose connections.
Check line voltage; if less than 90% or more than
110% of rated voltage consult a licensed electrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose wiring connections.
Motor internal terminal overload protector is open.
Motor runs too hot. Turn power to motor off.
Check for proper voltage.
Check for proper impeller or impeller rubbing.
If suction and discharge piping are not adequately
supported, pump assembly will be strained. Do not
mount pump on a wooden platform!
Securely mount on concrete platform for quietest
performance.
Disassemble pump, clean impeller, follow pump
service instructions for reassembly.
Improve suction conditions.
Increase pipe size.
Decrease number of fittings.
Increase discharge pressure.
1. Ensure that the communication cable is connected
at both ends.
2. Check that the IntelliFlo local address is set to "1".
3. Ensure that the IntelliFlo display says "DISPLAY
NOT ACTIVE", in case of IntelliPool.
A defective device on the network can inhibit the
