To avoid over-heating wire and excessive voltage
drop at motor, be sure that wire size is at least as
large as size listed in cable sizing tables for your
horsepower pump and length of wire run.

NOTICE When built-in overheating protection
is not provided, install an approved overload
input in full load amps. Select or adjust overload
element(s) in accordance with control instructions.
When built-in overheating protection is provided,
use an approved motor control that matches motor
input in full load amperes.
Rotation – (3 Phase only)
To make sure motor is running in the correct
direction, proceed carefully as follows:
After electrical connections have been made
as outlined, and with pump hanging in well
supported from clamp on the discharge pipe, turn
on then turn off the switch connecting the motor to
the power supply line.
connections are properly made, pump will "jerk"
clockwise when looking into the pump discharge
the motor is running in the wrong direction.
connect to the "lead" terminals in the magnetic
starter. With connections properly made, and pump
the pump should deliver water according to the
performance charts.

All recommended overload selections are of the
ambient compensated type to maintain protection
at high and low air temperatures.
All heaters and amp settings shown are based on

with a Wye-Delta starter, divide motor amps by
heaters carrying phase amps.
