INSTALLATION
which
may occur
in the piping
and foot valve as the
piping
is assembled.
Single
Pipe Ejector
Installation
Single pipe installations
require
(see Figure 9):
a. Galvanized
steel suction
pipe.
b. Leather
packer-type
ejector
with
built-in
foot
valve.
1.
2.
c. Turned
couplings
(supplied
with
packer-type
ejector).
d. Well casing
adapter
(supplied
with packer-type
ejector).
Connect
ejector
to first length
of pipe.
Use pipe
joint compound
sparingly
on male threads.
Lower
pipe
into casing.
Use special
turned
cou-
plings (included
with single pipe ejector
package)
to increase
water
flow. Use pipe joint compound
sparingly
on male couplings
threads.
Horizontal
Offset
Pipe Sizes
When
the pump
is set more than 25' to one side of the
well, increase
the horizontal
pipe
size to reduce
fric-
tion. Never use pipe smaller
than the pump
port size.

NOTICE:
Fill pipe with water
as each length
is added
to be sure foot valve and connections
do not leak.
3.
Add lengths
of pipe
until the ejector
reaches
the
proper
depth.
(Your well driller should supply this
information.)
NOTICE:
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 (see Figure 9, Page 7).
4.
To properly
seat the cup seals, after the ejector
is
correctly
positioned
move
the assembly
up and
down slightly. Water pressure
in the casing will then
soak the cup seals (see Figure 9). They should seal
in 2-3 hours after installation.
5.
With ejector
set, install well casing adapter. Remove
pipe holder. Align locating
lugs and tighten
adapter
to form seal with well casing.
Discharge
Pipe Sizes
1.
If increasing
discharge
pipe size, install reducer
in
pump
discharge
port. Do not increase
pipe size by
stages.
2.
When the pump
is set away from the points of water
use, the discharge
pipe size should
be increased
to
reduce pressure
losses caused by friction.
• Up to 100 ff run: 1"
• 100 ft. to 300 ft run: 1-1/4"
• 300 ft. to 600 ft rim: 1-1/2".
Pressure
Tank
Installation
- Deep
Well
The Pressure
Tank provides
a reservoir
of water under
pressure
and maintains
cushion
of air pressure
to pre-
vent pipe hammering
and possible
damage
to plumb-
ing components.
When
water
is drawn
off through
house fixtures,
the pressure
in the tank is lowered
and
the pressure
switch
starts the pump.
Standard
Tank Connection
When
a standard
tank
is
used,
an
air volume
control
(AVC) adds air to the tank when
it is needed.
See Figure
11 for typical
standard
tank installation.
To connect
AVC to pump,
thread
a 1/8" compression
fitting
into
tapped
hole on the front of the pump.
Cut tubing
to
length
to reach AVC; assemble
to fitting on pump
and
to AVC on tank. See installation
instructions
provided
with tank and AVC for details.
