Installation (Continued)

DISCHARGE PIPING

Install a 1-1/2” pipe tee in the pump discharge to allow easy priming. Plug the end of the tee opposite the pump to allow the branch piping to go to the spray nozzles (See Figure 1). Remove the pipe plug to fill the pump with water for priming.

CONNECTION TO WATER SOURCE

The maximum vertical suction lift from pump to the water level is 25 feet.

DRILLED WELL

1.Install a foot valve on the first section of pipe (see Figure 2).

2.Lower the pipe into the well.

3.Add pipe until the foot valve is 10 feet below the lowest anticipated water level.

Leaking joints or couplings will allow air to leak into the pipe and cause poor pump operation. Make sure to use pipe joint compound or Teflon® tape on all pipe connections.

Locate foot valve no closer than 2 feet

from the bottom of the well so sand or sediment is not drawn into the system.

4.After the proper depth is reached, install a well seal or pitless adapter to support the pipe.

5.Slope the horizontal pipe upward toward the pump to eliminate trapping air.

6.When using a foot valve, a priming tee and plug above the well seal is recommended.

DRIVEN WELL

•Drive the point several feet below the water table.

NOTE: A packer-type foot valve can be installed in the well (See Figure 3). This type of foot valve allows the well pipe to be filled with water when priming and makes the inlet pipe much easier to test for leaks. Follow the manufacturer’s instructions when installing the packer- type foot valve.

As an alternative, an in-line check valve can be used with a driven well (See Figure 4).

It may be necessary to supply the pump with multiple well points to maintain the high flow capability of this pump. Consult with a plumbing professional for appropriate materials and installation instructions.

Leaking joints or couplings will allow air to leak into the pipe and cause poor pump operation. Make sure to use pipe joint compound or Teflon® tape on all pipe connections.

And Spring Installation

•Install a foot valve on the inlet pipe and lower into the water.

Locate foot valve no closer than 2 feet

from the bottom of the water source so sand or sediment is not drawn into the system.

NOTE: When a lake is used for the water supply, make sure the suction pipe is deep enough to be submerged at all times. Slope the pipe upward toward the pump to eliminate trapping air. The pipe must be removed during winter months or protected against freezing.

Protect the pipe from damage by

swimmers and boaters.

Electrical Connections

Connect the pump to a separate electrical circuit with a dedicated circuit breaker. Refer to the electrical specifications in wiring chart for recommended circuit breaker and wire size.
