INSTALLATION
17. Develop
the well - See "Well Development
and
Pump
Test".
18. Before piping
up a Captive Air@ Tank, be certain
air pres-
sure in tank is the same as the cut-in pressure
of the pres-
sure switch.
For additional
information,
see instructions
on tank or in the tank owners
manual.

Installation
with Steel
Pipe
1. Read the
"Do It Yourself
Installation
with
Plastic
Pipe"
section
first. Information
on the following
items
will be found there:

2. Screw a length of galvauized
pipe into discharge
of pump.
3. With the pump
and pipe in vertical
position,
tape cable
to pipe just above and below
the splice connections.
4. Lower pump
into well and tape
cable to pipe every
10'
with plastic tape. For easy and safe handling
in lowering
pump
into well, it is advisable
to use a tripod with a block
and tackle.
A pipe holder
shotfld
always
be used to sup-
port the assembly
on top of the well casing
while making
up the next length
of pipe. See Figure 11 below.
IA CAUTION] Risk
of cable
damage
and
electrical
q
shock.
Never support
the weight
of the pump
and pipe
on the electrical
cable. Use the drop pipe for this purpose.
Protect
the cable from damage
when
lowering
the unit in
the well.
5. Add sufficient
length of pipe to tbe pump discharge,
using
pipe joint compound
on male threads,
until the pump
is
at the proper
setting.
The pump
should
not be set closer
than 5 feet from the
bottom
and should
be submerged
15 to 20 feet below
the
draw down water
level. If drawdown
level is not known,
set the pump
5 feet from the bottom
of the well.
6. Develop
the well - See "Well Development
and Pump
Test,"
below.
7. Refer
to Typical
Pump
Installation
Drawings
for
proper
method
of piping
depending
on the type of pres-
sure tank used.
Well
development
and pump
test
Proper
well development
will normally
clear out all solid ma-
terials in the well water.
It will also tell you if the well is ca-
pable
of supplying
the full capacity
of the pump.
If you are
not certain
of the draw
down
water
level in your well, this
can also be measured
after pumping
at maximum
flow for a
period
of time.
Well development
simply means
pumping
at very low flow
rate to start with and gradually increasing
the flow to its max-
imum.
The quality
of the water
must
be visually
checked
throughout
the procedure.
The amount
of time spent on well development
will vary de-
pending
on the condition
of the water.
Allow yourself
at
least
2 hours
continuous
running
and
do not
become
alarmed
if it takes 4, 5 or more hours
to clear up the water.
This well development
procedure
will assure
you of long,
no-pump
wear,
trouble
free operation.
Do not start
pump
with
discharge
open
unless
this de-
velopment
procedure
has been
done
and well
is clear.
1. Connect
temporarypiping
as shown
in Figure 12, below.
This includes
a gate valve for flow regulation.
2. Connect
motor
leads
and
electric
power
supply.
See
Figures 4 and 5, Page 6.
Do not
start
pump
yet!
3. Close the gate valve
and then
carefully
open
slightly
to
allow a small amount
of water to be pumped.
You can
now
start
your
putnp!
