TROUBLESHOOTING

Always disconnect power to the IntelliFlo
before servicing the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to electric
shock. DO NOT attempt to adjust or service without consulting your dealer or a qualified pool technician. Read the entire Installation
& User's Guide before attempting to use, service, or adjust the pool filtering system or heater.

Alerts and Warnings

The IntelliFlo Variable Speed Pump displays all alarms and warnings on the control panel display. When an alarm
®
or warning condition exists, the corresponding light will be lit on the display.
All control panel buttons are disabled until the alarm or warning is acknowledged with the Reset button. Pressing
the Reset button will clear the alarm once the fault condition has been resolved.
Note: The pump will not start if the impeller is rotating.
Power Out/OFF
The incoming supply voltage is less than 170 VAC. The drive faults to protect itself from over current. The drive
contains capacitors that keep it powered up long enough to save the current run parameters. If power is restored
during this process, approximately 20 seconds, the drive will not restart until completed.
Priming Failure
If the pump is not defined as primed within the "Max Priming Time" it will stop and generate a "Priming Alarm" for 10
minutes, then attempt to prime again. The "Max Priming Time" is set by the user on the priming menu as discussed
on page 16. If the pump cannot prime within five attempts it will generate a permanent alarm that must be manually
reset.
Overheat
If the drive temperature gets above 54.4° C (130° F) the pump will slowly reduce speed until the over
temperature condition clears.
Thermal Mode
When active, the motor will run at the preset RPM until the drive internal temperature increases above the
minimum. The pump's internal thermal protection is disabled when connected to an automation system. Thermal
protection is provided by selecting YES at the ON WITH FREEZE portion of the circuit function menu in the
automation control system. To re-enable the internal thermal protection, the power to the drive must be cycled
off then back on. Important: See explanation of Thermal Mode on page 17.
Over Current
Indicated that the drive is overloaded or the motor has an electrical problem. The drive will restart 20 seconds
after the over current condition clears.
Over Voltage
Indicates excessive supply voltage or an external water source is causing the pump and motor to rotate thereby
generating an excessive voltage on the drives internal DC buss. The drive will restart 20 seconds after the over
voltage condition clears.
Internal Error
Indicates that the self-monitoring motor control software has encountered an error. Clear the alarm and restart the
pump. If this alarm persists, contact Pentair Technical Service at 1-800-831-7133.
