Installation
12. Apply gasket to adapter flange. Be sure holes line up.
13. Align locating lugs on pump base with locating lugs
on adapter flange; attach pump to flange with cap
screws provided.
14. See "Discharge Pipe Sizes" for information regarding
correct discharge pipe size.

E. Offset nipple (supplied with jet package)
F. Pipe holders (see Figure 6B)
1. Place jet in pail of water for two or more hours to
soak cup seals. See Table III for proper venturi and
nozzle.
2. After cup seals are thoroughly soaked, connect jet to
first length of pipe. Use pipe joint compound sparing-
ly on male threads.
NOTICE: Due to normal irregularities in the leather of
the cup seals and the inner walls of the drop pipe, 2"
packer jets do not form a perfect seal. In a dormant
system, water will leak back into well over time and
pump will normally start and cycle to maintain sys-
tem pressure level.
3. Lower pipe into casing. Use specially turned cou-
plings (included with 2" single pipe jet package) to
increase water flow. Use pipe joint compound spar-
ingly on male couplings threads.
NOTICE: Fill pipe with water as each length is added
to be sure foot valve and connections do not leak.
4. Add lengths of pipe until jet reaches proper depth.
(Contact your local well driller.)
IMPORTANT: As a guide, the jet should be set at least
10 to 20 ft. (3-6M) below lowest water level with
pump running, but always at least 5 ft. (1.5M) from
bottom of well.
5. With jet at the proper depth for your installation,
mark the drop pipe 6" above the top of the well cas-
ing, then raise the drop pipe about 18 inches and
clamp it there to allow room to install the casing
adapter, offset nipple, and adapter flange.
6. Cut off the drop pipe at the mark you made in Step 5.
Thread the top of the pipe 1" NPT to take the adapter
flange.
7. Slide the casing adapter over the top of the drop pipe
with bolts in place and leave it loose on the pipe.
8. Thread the drop pipe into the adapter flange; thread
the offset nipple into the adapter flange until it is tight
and aligns with its port inthe casing adapter.
9. Remove pipe holder and lower pipe assembly until
casing adapter seats on well head and offset nipple
seats in casing adapter port. Before tightening casing
adapter bolts, move assembly up and down slightly.
Water pressure in the casing will seal the cup seals.
10. Tighten casing adapter bolts to fasten the casing
adapter to the well casing.
11. Install gasket on adapter flange and bolt pump to
adapter flange.
IMPORTANT: Align locating lugs on adapter flange
and pump base so that pump discharge will be
aligned with piping.
