BEFORE YOU INSTALL YOUR PUMP

NOTE: For proper performance, pump MUST be matched to ejector and to

well depth. Use shallow well installation for wells up to 25 ft depth to water and deep well ejector for depths up to 130 ft.

Step 1. Long runs and many fittings increase friction and reduce flow.

Locate pump as close to well as possible: use as few elbows and fittings as possible.

Step 2. Be sure well is clear of sand. Sand will plug the pump and void the

warranty.

Step 3. Protect pump and all piping from freezing. Freezing will split pipe,

damage pump and void the warranty. Check locally for frost protection requirements (usually pipe must by 12” below frost line and pump must be insulated).

Step 4. Be sure all pipes and foot valve are clean and in good shape.

Step 5. No air pockets in suction pipe.

Step 6. No leaks in suction pipe. Use Teflon tape or Plasto-Joint Stik to seal

pipe joints.

Step 7. Match pump to well.

IMPORTANT: Flow into well must at least equal flow out through pump!

Step 8. Unions installed near pump and well will aid in servicing. Leave

room to use wrenches.

Step 9. Plug 1” drive port when installing on shallow well.

SHALLOW WELL/CENTRIFUGAL INSTALLATION

No ejector is used in this case, plug the smaller of the two inlet ports, using the larger for the suction pipe. Refer to Figure 6 for installation tips. Maximum depth to water for shallow well/centrifugal operation is 25 feet.

NOTE: To avoid pump overloading and motor failure, install a flow control valve at the discharge to limit flow to 20 gallons per minute.

Well Casing

PIPING IN THE DEEP WELL

See Figures 7 and 8.

NOTE: Deep well installations are either single pipe (2” wells) or double pipe (4” and larger wells). In a double pipe installation, the larger pipe is the suction pipe and the smaller pipe is the drive pipe (very deep wells may use suction and drive pipes of the same diameter).

Plastic pipe is ideal for double pipe installations. Due to its light weight, it is easy to handle and does not usually require a block and tackle for installation and removal.

PLASTIC PIPE INSTALLATION – DOUBLE PIPE

NOTE: Use Teflon tape on all male threads on plastic pipe and fittings to

prevent air leaks in suction piping.

Step 1. Inspect ejector to make sure that nozzle and venturi openings are

clean and clear.

Step 2. Inspect pipe for any foreign matter or obstructions.

IMPORTANT: Make sure that no foreign matter enters pipe openings while installing pump.

Step 3. Make sure foot valve operates freely: attach to ejector with a close

nipple. Use Teflon tape on male threads.

Step 4. Install nozzle and venturi in deep well ejector.

Step 5. Using Teflon tape on male threads, install special plastic pipe

adapter (supplied with ejector) by screwing adapter into 1-1/4” tapped hole in ejector body (see Figure 7A).

Step 6. Thread a 1” plastic pipe adapter into the 1” tapped hole in ejector

body (see Figure 7A).

Step 7. Install sufficient plastic pipe in well casing to place ejector at the

proper depth. (Your well driller should supply this information.)

IMPORTANT: as a guide, the ejector should be set at least 10 to 20 feet below the lowest water level with pump running, if possible, but always at least five feet from the bottom of the well.

Step 8. Tighten all hose clamps securely on plastic pipe. Use two clamps

per joint to prevent air leaks into suction pipe. Clamp screws should be on opposite sides of the pipe. Fill pipes with water to make sure that foot valve and connections do not leak.

Step 9. Install sanitary well seal on top of well casing; use steel nipple

through well seal as shown in Figure 7A.

IMPORTANT: align locating lugs on adapter flange and pump base so that pump discharge will be aligned with piping.

Step 10. Install 1” nipple in one side of adapter flange. Slide threadless

coupling down over drive pipe from well. Thread adapter flange onto suction pipe from well and align nipple and drive pipe.

Step 11. Slide threadless coupling up and secure nipple to drive pipe.

Step 12. Remove paper backing from adhesive gasket. Apply gasket to

adapter flange, making sure that holes line up.

Step 13. Align locating lugs on pump base with locating lugs on adapter

flange; attach pump to flange with cap screws provided.

Step 14. See “Discharge Pipe Sizes” for information regarding correct dis-

charge pipe size.
