A.3.3. WIRING
All electrical work should be performed by qualied personnel and in accordance to applicable electrical
codes, best practices and safety standards. All wiring must conform to federal, state and local electrical
codes.
A.3.3.1. PROCEDURE TO WIRE THE SPRAY PUMP MOTOR
1. Remove the cover (spray pump) motor junction box and pull the leads to connect the power supply.
2. Wire the pump motor following the wiring diagram placed in the motor. Ensure that the motor is
properly grounded.
3. Procedures for verifying shaft rotation:
If the shaft is visually accessible verify that is rotating in the correct direction (to the outlet of the pump
motor) as indicated by the arrow cast on the pump volute.
If the motor is sealed and you have no visual access to the shaft, use a pressure gauge on the pump, if there
is no pressure, change the shaft rotation.
4. For 3-phase motor only, momentarily energize the motors to ensure that the rotation is correct as
indicated by the arrow cast into the pump volute. If rotation is incorrect, interchange two wires at the
motor starter terminals T1 and T2.
Check the voltage and phases of the incoming power source. Wire the motor per
manufacturer’s instructions for proper installation.
CAUTION
Electrical wiring must be handled ONLY by qualied personnel. Failure to do so
may result in severe personal injury or property damage.
CAUTION
This equipment is powered by a three-phase alternating current, as specied on
the serial tag and data plate. A properly sized ground wire from the incoming
power supply must be connected to the chassis ground terminal inside the electrical
enclosure.
Improper grounding can result in severe personal injury.
Always disconnect, tag and lock the incoming main power source before opening
the electrical enclosure.
