NOTICE: Dual-voltage
motors are factory wired for 230 volts. If nec-
essary, reconnect
the motor for 115 volts, as shown.
Do not alter
the wiring in single voltage
motors.
Install, ground,

in compliance
with
the National

Electrical
Code
(CEC), as applicable,
and with all local codes and ordinances

Connection
Procedure:
1.
Connect
the ground
vdre
first as shown
in Figure 4_ The
ground wire must be a sold copper
wife at least as large as the
power
supply wires.
2.
There must be a sofid metal connection
between
the pressure
switch
and the motor for motor grounding
protection.
If the
pressure
switch
is not connected
to the motor,
connect
the
green ground
screw
in the switch to the green ground
screw
under the motor end cover. Use a solid copper
wire at least as
large as the power
supply wires.
3.
Connect
the ground wire to a grounded
lead in a service panel,
to a metal undeeground
water
pipe, to a metal well ca_mg at
least ten feet (3M) long, or to a ground
electrode
provided
by
the power
company
or the hydro authority.
4.
Connect
the power
supply
wires
to the pressure
switch
as
shown
in Figure 4.
