In some cases, your pump ownerSmanual may stillshow hori-
zontal casing adapter instaJlations.If so, disregard, and follow
these instructions.
INSTALL JET
1. Presoak the leathers on the leather packer-type jet. This
can be done by placing the jet in a pail of water until
leathers are soft. For best results, soakovernight.
2. Connect thejet to the first length ofsuction pipe, 1-1/4" pipe
for 2" and 3" casings.
CAUTION: 2" casingsizes require special turned couplings,
Do NOT use ordinary pipecouplings as you will restr;,ctthe
flow of water, andreduce the pump capacity.
3. Lower the jet and pipeassembly into the well casing, adding
additional lengths of pipe until proper depth is reached.
Tighten each joint as lengths are added. Use pipe
compound sparingly,and on male threads only.
4.After the correct depth is reached, move the jet up and
down slightly to help seat the leathers, Water pressure will
complete the sea_ng of the leatherSagainst the casing wall.
Be certain to leave sufficient pipe above the well casing to
allow for installation of the casing adapter and hook-up of
off-set piping. Supportthe suction pipe with a pipe clamp or
other suitable device just above the casing. To check the
foot valve for leakage, fill the pipes with water. The pipes
should remain full.
INSTALL CASING ADAPTER
1. Securely thread a 1"elbow onto the 1"x 6"nipple furnished.
2. Slide adapter over the 1-I/4" suction pipe and onto the well
casing as far as it willgo.
3. Securely thread 1-1/4" elbowonto the 1-1/4" suctionpipe.
4. Slide the 1" nipple assembly into casing adapter drive hole
as far as it willgo, Be certain it extends through the rubber
packing.
5. Position the 1-1/4" suctionline with respect to the t" drive
line as shown in illustrations.
6. Tighten three (3) belts to seal adapter to casing and piping
to adapter.
