11.0 TROUBLESHOOTING
11.1 Power LED and LCD Screen Not Turning On
11.1.1 Check to make sure either 120 VAC or 240 VAC input power is connected to the
proper screw terminals at the control. Verify input voltage with a voltmeter. If there
is input power, the circuit breaker may have tripped. The CPSC Series is protected
by a 5 amp circuit breaker located at the base of the power pack. To reset the
circuit breaker press the small yellow pin back in. Main power to the unit must be
turned off prior to resetting the circuit breaker. Should the circuit breaker continue to
trip after this exercise then you should consult Compu Pool for assistance.
11.2 Water Fault LED Illuminated
11.2.1 The power unit has sensed a no-flow condition and has stopped generating
chlorine. Check that there is water in the cell enclosure. If there is adequate flow
and the LED is still on, determine if salt has been added to the pool. If no salt has
been added, the no flow light will be illuminated. If the LED is still illuminated check
the connection between the cell plug connectors and the brass cell terminal posts.
11.3 Low or No Chlorine Residual
11.3.1 The possible cause may be one or more of the following:
 Insufficient chlorine output %
 Insufficient running times
 Insufficient or excessive stabilizer
 pH too high
 Salt content below 2500 ppm
 Check wire connections
 Check circuit breaker on Power Unit
 Check that filter pump running
 Check that water flow through Cell is sufficient
 Cell needs cleaning
11.4 Water Flow Through Cell is Low
11.4.1 The possible cause may be one or more of the following:
 Check for air in system
 Check operation of pump
 Check filter is clean
 Check water level in pool
 Check for blockage in skimmers and/or plumbing
