TECHNICAL DATA
WARNING: DISCONNECT POWER SOURCE BEFORE CHECKING. DO NOT MAKE
ANY CHANGES WITH POWER ON.
VOLTAGE CHANGES ARE MADE INSIDE THE MOTOR COVER, NOT IN THE PRESSURE SWITCH.
VOLTAGE CHANGE PROCEDURE AND TERMINAL BOARD DESIGN
Jet pump motors have a voltage plug to facilitate simple voltage changes from 115V to 230V. All ½ HP motors
are factory wired for 115V operation. If wired for 115V, operation at 230V will destroy the windings in a matter of
seconds and will not be covered by warranty. Larger HP motors are factory wired at 230V.
A.O. Smith / Century Terminal Board Design:
• L1 has two (2) male terminals, one switch wire is attached to one terminal.
• L2 has two (2) male terminals, one switch wire is attached to one terminal and when set up for 115V operation the
voltage plug is connected to the other.
• "A" has 1 male terminal, the voltage plug is always connected to "A".
A.O. Smith / Century Voltage Change: failure to follow these instructions may damage the windings
• 115V - Place the Black voltage plug on the open L2 male terminal and the "A" terminal.
• 230V - Place the Black voltage plug only on the "A" male terminal. The 2nd L2 male terminal will be open.

■ Pumps are Pre-Wired by HP:
DANGER
• ½ hp wired for 115 volts
• ¾ hp - 1½ hp and larger wired
for 230 volts
• 2 hp is 230 volt only
