Mounting instructions
Mounting the assembly
Do not operate the pump unless the assembly is securely and properly mounted.
Misalignment of the motor/pump assembly or not having the assembly reasonably level may cause pump vibration,
noisy operation, fluid leaks, or air leaks and air locks in the suction pipe.
1. Place the motor/pump assembly in its intended operating position.
2. Level the pump through the centerline of the motor/pump assembly suction port.
initial Operation
Make certain the motor is not connected to a power source until the motor is properly assembled and mounted.
Serious personal injury or damage to the motor/pump assembly could occur if the motor is activated improperly.
Only certified electricians should make electrical connections.
1. Prime the pump by adding fluid to the volute case through the top plug.To properly prime the pump, venting
may be required.
2. Check the nameplate on the motor to determine the correct wiring procedure for your intended power source
and if the motor is single or three phase. Connect the motor to a power source by following the wiring proce-
dure
on the motor's nameplate.
note:
a. Single phase motors are typically dual voltage. In some cases, three phase motors are tri-voltage. Check the
nameplate and follow the proper wiring procedure for the voltage you are using. Improperly wiring the motor
could result in damage to the motor.
b. Three phase motors require a control box. Install overload protection to help prevent motor damage.
c. Depending on the wiring, three phase motors may start in reverse. Interchange any two power leads to
change the starting direction and pump rotation.
• Always follow correct operating procedures.
• Always disconnect the motor/pump assembly from all power sources before servicing the pump or motor.
• Periodically check all power connections, bolts, screws, and the motor's mounting.
• Failure to properly follow assembly and operating instructions could result in damage to the pump and motor.
• Failure to properly install the impeller and impeller nut could result in damage to the pump and could cause
serious personal injury.
