Compu Pool CPSC Series Manual 10
7.2 Wiring
7.2.1 Power must be shut off at the circuit breaker before performing any wiring. Be sure
to follow local and NEC electrical codes. The Compu Pool CPSC Series chlorinator
has been designed to easily wire into typical in-ground pool systems. To provide
safe operation, the unit must be properly grounded.
7.2.2 The Power Unit comes with a terminated power cord which is typically connected to
an external timer, which will turn the pump and Power Unit on and off together. As
all individual wiring set ups are unique, have the Power Unit wired to the load side
of the external timer by a qualified person.
7.2.3 In Canada and in some parts of the United States, the Power Unit must be
connected to a circuit protected by a Class A ground fault interrupter (GFI). Check
local codes before connecting.
7.2.4 The Compu Pool CPSC Series is shipped from the factory with a 240 VAC
configuration.
7.3 Changing the Wiring to 120 VAC
7.3.1 Power must be shut off at the circuit breaker.
7.3.2 Remove the six screws from the rear of the Power Unit.
7.3.3 Lift the housing cover off the backing plate.
7.3.4 Refer to Figure 1 for the 120 VAC configuration, moving only the wire on J12 to J11
and the wire on J8 to J14.
7.3.5 Ensure that the gray ribbon cable is secure at both ends.
7.3.6 Replace the housing cover. All wires must be enclosed within the housing so that
they are not pinched between the housing cover and the backing plate.
7.3.7 Replace the six screws in the base of the Power Unit.
