IMPORTANT! IntelliChlor (SCG) AC transformer wiring Instructions: When using the EasyTouch
PL4/PSL4 Control Systems with the IntelliChlor (SCG) option , be sure the IntelliChlor (SCG) AC
transformer conductors are connected to the LOAD SIDE OF THE MAIN FILTER PUMP RELAY located
in the enclosure (see page 20). This ensures that the IntelliChlor cell produces chlorine only when the
main filter pump is on. This method does not require a ground fault circuit-interrupter (GFCI) for the
IntelliChlor power center.
TO AVOID AN ELECTRICAL HAZARD AND EQUIPMENT DAMAGE TO THE ENCLOSURE
AND INTELLICHLOR CELL: FIRST DISCONNECT AC POWER TO THE ENCLOSURE
BEFORE CONNECTING THE INTELLICHLOR COMMUNICATION CABLE.
Connect the IntelliChlor (SCG) transformer conductors to the main filter pump relay as follows:
1.
Switch OFF AC power
to the Power center at the house panel circuit breaker.
2. Loosen the two retaining screws securing HIGH VOLTAGE FRONT COVER PANEL.
Remove the panel from the enclosure (see illustration below).
3.
Locate the FILTER PUMP RELAY. Connect the IntelliChlor SCG transformer
conductors to the LOAD SIDE of the relay. See relay wiring diagram shown on page
20.
4. After electrical connections have be completed, install the HIGH VOLTAGE FRONT COVER
PANEL and tighten the two retaining screws to secure in place.
5.
Switch AC power ON
to the Power Center.
BEFORE REMOVING THE HIGH VOLTAGE COVER PANEL FROM THE POWER
CENTER,
switch OFF the main power at the house circuit breaker box.
