Step 7. Install enough plastic pipe in well casing to put ejector at the
proper depth. (Ask your well driller for 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 2.
IMPORTANT: Align locating lugs on adapter flange and pump base so that
pump discharge aligns with piping.
Step 10. Install 1" (1-1/4") 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 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.
SINGLE PIPE EJECTOR INSTALLATION
Single pipe installations require (see Figure 3):
a. Galvanized steel pipe
b. Leather packer-type ejector with built-in foot valve
c. Turned couplings (supplied with packer-type ejector)
d. Well casing adapter.
Step 1. Connect ejector to first length of pipe. Use pipe joint compound
sparingly on male threads. Consult Table II for proper venturi and
nozzle.
2357d 0797
Step 2. Lower pipe into casing. Use special turned couplings (included
with 2" single pipe ejector package) to increase water flow. Use
pipe joint compound sparingly on male couplings threads.
NOTE: Fill pipe with water as each length is added to be sure foot valve
and connections do not leak.
Step 3. Add lengths of pipe until the ejector reaches 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 5 feet above the bottom of the well.
Step 4. To properly seat the cup seals, after the ejector is correctly posi-
tioned, move the assembly up and down slightly. Water pressure
in the casing will then soak the cup seals. They should seal within
2-3 hours after installation.
Step 5. With ejector set, install well casing adapter. Align locating lugs
and tighten adapter to form seal with well casing.
