SCG Transformer Removal and Installation
To remove the SCG transformer assembly (see Figure 1 & 2, page 7 & 8):
1. Remove the screw securing the green ground wire and the circuit
breaker bracket to the enclosure.
2. Remove the two remaining screws securing the circuit breaker bracket
to the enclosure to access the circuit breaker leads.
3. Disconnect RED transformer wire (1/4” quick-disconnect) from the rear
of the 12 A circuit breaker.
4. Disconnect the other RED transformer wire (3/16” quick-disconnect)
from the circuit board terminal.
5. Remove the transformer ground wire screw.
6. Disconnect all the SCG transformer primary leads.
7. Remove the three remaining screws securing the transformer. Remove
the transformer from the enclosure.
To install the transformer assembly (see Figure 1 & 2, page 7 & 8):
1. Mount the transformer onto the back panel of the enclosure. Secure the
transformer with three #8-32 x 3/8” screws.
2. Install the GREEN transformer ground lead screw and remaining
screw.
3. Connect the red transformer wire (1/4” quick-disconnect) onto the rear
of the 12 A circuit breaker.
4. Connect the other RED transformer wire (3/16” quick-disconnect) onto
the circuit board terminal.
5. Install the circuit breaker bracket onto the enclosure and secure with
two #8-32 x 3/8” screws.
6. Secure the green circuit board ground wire to the enclosure with
#8-32 x 3/8” screw.
7. Connect the transformer primary AC wires as required. See “Figure 3:
SCG Transformer AC Wiring Diagram” on page 9 for transformer AC
wiring information.
See IMPORTANT NOTE below for required SCG transformer filter
pump relay connection information:
Before removing and installing the SCG transformer, first be sure
to switch OFF the main AC power to the load/power center.
IMPORTANT! IntelliChlor (SCG) AC Wiring Instructions: When
using the IntelliChlor salt chlorine generator and an IntelliFlo pump
(or 2-speed pump) with a Pentair Water Pool and Spa®IntelliTouch®,
EasyTouch® automation control system , the IntelliChlor AC power
center wires must be connected to the PUMP SIDE OF THE MAIN
FILTER PUMP RELAY located in the load/power center. This ensures
that the IntelliChlor cell produces chlorine only when the main filter
pump is on. This method does not require a separate ground fault
circuit-interrupter (GFCI) to protect the circuit.
