Pump Motors
Pumps are shipped from the factory with motors wired according to the specifications given
on the order as to kind of current, frequency, and voltage.
Very often on installation, it becomes necessary to change the original setting to suit the AC
power source. To do this, locate the motor change-over plate, typically located on the shaft end
of the motor and remove the screw which secures it in place. Slide the plate so that the
required voltage as marked on the plate, lines up with the screw hole. Reinsert the screw and
secure the plate in place.
Many motor failures result from improper setting of the motor change-over plate. If set for
115 VAC and 230 VAC feed is used, the motor will burn out after running only a short time. If
set for 230 VAC and 115 VAC feed is used, the motor will run very slowly and the starting
field will soon burn out.
Motor Loads
The following table shows the maximum running amperage that can be expected for the pump
motor, unless noted otherwise.

Notes: 1) Inadequate feed wiring (too long or too small a diameter wire) will increase current
draws on the motor and/or reduce voltage at the motor. This may also reduce motor
life.
2) These numbers do not account for the higher load upon start-up, nor up to one
additional Amp associated with other electrical components (lights, solenoid valves,
and so on).
3) All model numbers ending in TWIM or TW2 have one pump motor per side. 9140K
and 9840K also have one pump motor per side.
4) The 9140K and 9840K models must use no less than a 20 A breaker to account for
the high current upon start-up.
