Piping In The Deep Well; Double Pipe Installation - Plastic Pipe - Craftsman 390.2532 Owner's Manual

INSTALLATION
NOTICE: For proper performance, pump MUST be
matched to ejector and to well depth. Use this pump
on wells 25' to 210' deep.
1. Long runs and many fittings increase friction and re-
duce flow. Locate pump as close to well as possible:
use as few elbows and fittings as possible.
2. Be sure well is clear of sand. Sand will plug the
pump and void the warranty.
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).
4. Be sure all pipes and foot valve are clean and in
good shape.
5. No air pockets in suction pipe.
6. No leaks in suction pipe. Use Teflon tape or Plasto-
Joint stik to seal pipe joints.
7. Match pump to well.
IMPORTANT: Flow into well must at least equal
flow out through pump!
8. Unions installed near pump and well will aid in ser-
vicing. Leave room to use wrenches.
I_, CAUTION]Motor normally operates at high temper-
ature and will be too hot to touch. It is protected from
heat damage during operation by an automatic internal
cutoff switch. Before handling pump or motor, stop
motor and allow it to cool for 20 minutes.
Piping In The Deep Well
See Figures 6, 7, and 8.
NOTICE: Deep well instaUations are either single pipe
(2" wells) or double pipe (4" and larger wells). In a dou-
ble 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 instaUations. Due to
its light weight, it is easy to handle and does not usually
require a block and tackle for instaUation and removal.
Double Pipe Installation - Plastic Pipe
NOTICE: Use Teflon tape on all male threads on plastic
pipe and fittings to prevent air leaks in suction piping.
1. Inspect ejector to make sure that nozzle and ven-
turi openings are clean and clear.
2. Inspect pipe for any foreign matter or obstructions.
NOTICE: Make sure that no foreign matter enters pipe
openings while installing pump.
3. Make sure foot valve operates freely: attach to ejec-
tor with a close nipple. Use Teflon tape on male
threads.
.
5.
Install nozzle and venturi in deep well ejector.
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 Figures 6 and 8 below).
