Piping Instructions
• Properly support all suction and discharge piping to avoid strain on the pump.
• Piping should match the pump inlet and outlet connection sizes.
• For long runs, increase connections by one pipe size.
• Use pipe thread sealant.
• Avoid the use of unions on the suction line if possible. All suction line connections must be airtight.
• Do not over-tighten piping connections.
Suction Line
Suction Lift Applications
NOTE:
The total suction lift should not exceed 25 feet.
1. Install a new, clean pipe or hose.
• Make sure piping rises vertically or is sloped continually upward from the water source to the
pump inlet connection.
• Check that there are no high spots that cannot be evacuated of air during the priming process.
2. Install a strainer at the end of the suction line.
• Ensure the strainer remains well submerged at all times.
Discharge Line
1. Tighten the discharge pipe, using an opposing pipe wrench on the pump discharge.
2. Install a check valve.
• All discharge piping must have a pressure rating capable of withstanding the incoming inlet
pressure plus the pump’s maximum shut-off head pressure.
IMPORTANT:
Do not operate the pump under a no-flow/shut-off head condition.
Electrical Connections
1. An electrician should be employed to do the wiring.
2. Provide a separate circuit from the distribution panel to the pump unit, properly protected with a
fuse or circuit breaker.
3. Install a proper fused disconnect switch in the line. Make sure the correct gauge of cable is used to
carry the load.
IMPORTANT:
Undersized wire between the motor and the power source will adversely limit the
starting and load carrying abilities of the motor.
4. Wire the motor according to the motor nameplate to achieve clockwise rotation when viewed from
the motor end.
• Very long leads will require a larger cable.
• If needed, remove motor end compartment for viewing.
5. Make sure the insulated green or bare ground wire is securely connected to the green ground termi
-
nal screw on the motor terminal board.
Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power before working on or around the system.
