Power indicator lamps are provided on the
distribution box and on the feedback
sensor. The lamp on the distribution box
located next to the ON/OFF switch is
illuminated whenever power is supplied to
the control cable. The LED on the
feedback sensor will flash when the sensor is
receiving pulses from the flowsensor. These
LEDs help to ease tracing of power supply
faults and eliminates some of the guesswork
in troubleshooting. This feature is
referenced in the troubleshooting guide.

the following conditions are met:
q All hose connections correct and tight
(Refer to appropriate system plumbing
