Motor Voltage Change
The General Electric and Emerson jet pump motors both have a voltage change switch for ease of changing operating voltage
from low (115 volt) to high (230 volt) operation. The GE switch must be pulled out, rotated and pushed in. The GE motor switch
is marked HI (for 230 v) and LO (for 115 v). The Emerson switch is a toggle that can be changed using a pen tip or a small
screwdriver. The Emerson motor switch is marked 115 and 230.
It is an industry standard procedure to ship
CAUTION
power supply will damage the motor windings, and/or the capacitor, and/or the overload protector. This
damage is easily diagnosed and will not be covered as a warranty failure.
Motors of
3
⁄
hp and larger are factory wired for 230 volts. Connecting them to a 115 volt power supply without changing the
4
voltage switch will result in poor performance, noisy operation and overload tripping due to high heat.
