GENERAL PUMP INFORMATION

Typical Pump Setup
Typical setups for lawn sprinkler pump systems include ground water wells (Fig. 1) or surface water, such as lakes, ponds or streams. (Fig. 3)

Location
For best performance, the pump must be located as close to the water source as possible and protected from the elements.

Ventilation
Ventilation and drainage must be provided to prevent damage to the motor from heat and moisture.

Freezing
The pump and all piping must be protected from freezing. If freezing weather is forecast, drain pump or remove completely from the sprinkler system.

Water Supply
The water source must be able to supply enough water to satisfy the capacity of the pump and water needs. See performance chart.
WARNING: NEVER run pump against a closed discharge. Doing so can boil water inside pump, causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling pump. (Fig. 2)

Vertical Lift
Vertical lift is the vertical distance from the lowest level of the water to the pump intake. The pump will move water as long as the pump is within 25 vertical feet of the water source.

Horizontal Distance
The horizontal distance is the horizontal measurement between the pump inlet and the water source. This distance may affect the ability of the pump to operate. If it is over 60 feet, call customer service at 1-866-994-4148.

Pipe And Fittings
Use galvanized steel or NSF PW Schedule 40 PVC pipe and fittings. This material is designed for water pressure and will seal against air and water under pressure. Do Not Use: DWV fittings, as these are designed for drains without pressure and will not seal properly.

CAUTION: The entire system must be air and water tight for efficient operation and to maintain prime.

Wire Size:
The wire size is determined by the distance from the breaker box to the pump motor, and the horsepower rating of the motor. See the wire chart for proper wire size.

PUMP PREPARATION FOR WELL AND SURFACE WATER

CAUTION: Dry-fit entire assembly to ensure proper fit before gluing or taping parts.
CAUTION: Follow all proper gluing procedures as specified by the glue manufacturer. Always glue in a vertical direction whenever possible to prevent glue from dripping inside pipe or fittings
CAUTION: Use thread tape and a thread paste compound on all male threads except for the unions. Tighten securely with a wrench and add another 1/4 turn to ensure proper seal.

1. Thread 1-1/2 in. MPT x 1-1/2 in. slip adaptor into the outlet port located at the top of the pump.

2. Glue a 6 in. piece of 1-1/2 in. pipe into the adaptor.

3. Glue a 1-1/2 in. tee to the pipe.

4. Glue a 1-1/2 in. slip x 1-1/4 in. adaptor to the top opening of the 1-1/2 in. tee.

5. Thread in a 1-1/4 in. priming plug or optional priming plug with pressure gauge.
   NOTE: Hand tighten only, as this will be removed for priming.

6. Glue another 6 in. section of 1-1/2 in. pipe into the opening in the 1-1/2 in. tee.

7. Glue the male thread side of a 1-1/2 in. union to the pipe.

8. Thread 2 in. MPT x 2 in. slip adaptor into the inlet port located on the front of the pump body.

9. Glue an 8 in. section of 2 in. pipe into the 2 in. adaptor.

10. Glue one side of a 2 in. union to the pipe.
    For Well Installations

11. Thread a 2 in. MPT x 2 in. slip adaptor into the foot valve.

12. Glue 2 in. pipe into the adaptor. Glue enough sections of pipe together using 2 in. couplers in order for the foot valve to be completely submerged in water. Be sure inlet pipe

13. will remain fully submerged at the lowest expected level of the water source.
    Install well seal in order to hold the inlet pipe in position in the well.

14. Glue a 90º elbow when the inlet pipe is in line with the inlet port of the pump.
    For Surface Water Installations
    For surface water installations, follow steps 11 and 12 above and then:

15. Glue a 45º elbow when the inlet pipe is in line with the inlet port of the pump.

16. Support inlet pipe with pipe support.

1. Mount pump on a solid foundation as close to the water source as possible.
   CAUTION: Support the 2 in. inlet pipe from the well or lake to the inlet port to prevent sagging. Sagging will create air pockets within the pipe that will prevent the pump from priming and operating correctly.

2. Glue female 2 in. union to the end of inlet pipe leading from the water source.

3. Connect the 2 in. union together to complete the inlet line to the pump.

4. Glue a 6 in. piece of 1-1/2 in. pipe to the female portion of the 1-1/2 in. union.

5. Glue 1-1/2 in. ball valve to the other end of the 6 in. piece of pipe.

6. Connect the 1-1/2 in. outlet pipe to the sprinkler system by gluing in additional sections of pipe as needed.

7. Connect union to ensure proper fit. Do not tighten until after priming.
   CAUTION: Do not glue union together.

   • a. Using a pair of needle nose pliers, pull the gray wire with the female flag connector from the “B” terminal spade post. Place it to the left on the “A” terminal space post.
   • b. Pull the red wire with the female flag connector from the “B” terminal. Place it to the right on the L2 terminal space post.
   • c. Reinstall the rear motor cover.

PUMP PRIMING & STARTUP

CAUTION: All pumps must be primed by filling the pump cavity with water before they are first operated. This may take several gallons of water, as the entire inlet line will be filled in addition to the pump cavity. The longer the inlet line, the more water is required for priming.

1. Disconnect the 1-1/2 in. outlet union and separate the pipe.

2. Remove the air relief plug on top of pump and the 1-1/4 in. priming plug with pressure gauge or plug. Refer to Pump Preparation Step 5.

3. Slowly fill pump cavity until water comes out of air relief hole on top of the pump.

4. Replace air relief plug and continue adding water to pump cavity until water comes out of the open outlet pipe at the open union.

5. Wait 10 minutes to see if water level drops below the pipe tee. If level drops, check foot valve. If level stays constant, replace the priming plug.

6. Reconnect 1-1/2 in. union on outlet pipe. Open the ball valve (turn handle to line up with pipe), and then turn on breaker to start pump.
   IMPORTANT: If the pump fails to prime within five minutes:

7. Turn the power off at the break box. Check all pipe connections for leaks, making sure all connections are water and air tight. Check the inlet pipe for any sagging, making sure the inlet pipe is in a straight line to the pump. Watch for leaks or a milky color in the discharged water, which indicated an air leak. Re-prime if necessary, following steps 1 through 6 above. Reset breaker at the breaker box.

IMPORTANT: If the pump hums instead of pumping or turns off repeatedly, shut pump off immediately. Check voltage. Pump is wired to run on 230 volts. If the pump cuts out or stops, you may be attempting to connect to 115 volts. See PUMP ELECTRICAL INSTRUCTIONS to see how to correctly change the motor voltage to 115 volts.
