INTRODUCTION
We suggest
you take a few
minutes
to read the instructions
con-
tained in this manual
before
installing
and using your pump.
This
will help you obtain
the full benefits
of the quality
and convenience
built into this equipment.
It will also help you avoid
any needless
service
expense
resulting
from causes
beyond
our control
which
naturally
cannot
be covered
in our warranty.
RULES FOR SAFE INSTALLATION
AND
OPERATION
1.
Read
the
Owners
Manual
and
Rules for Safe Operation
and
installation
Instructions
carefully.
Failure to follow
these
Rules
and Instructions
could cause
serious
bodily injury,
and/or
prop-
erty damage.
2.
Check your
local electrical
wiring
codes
before
installation.
If
your local codes
are not followed,
your pump
will not work
to
its full rated
capacity.
If in doubt,
contact
your
local
Power
Company.
3.
Be certain
your
pump
installation
meets
all local
plumbing,
pump
and well codes.
4.
While installing
the pump,
always keep the well covered
to pre-
vent leaves and foreign
matter from falling into the well and con-
tanlinating
the water
and/or
causing
possible
serious
damage
to
the mechanical
operation
of the pump.
5.
Always
test the well water
for purity
before
using. Check
with
local health
department
for testing
procedure.
6.
Before
installing
or servicing
your pump,
BE CERTAIN
pump
power
source
is disconnected.
7.
Be sure your pump
electrical
circuit
is properly
grom_ded.
8.
Complete
pump
and piping
system
MUST be protected
against
below
freezing
temperature.
Failure to do so could cause
severe
damage
and voids the Warranty.
9.
Make sure the line voltage
and frequency
of t he electrical
circuit
supply
agree
with
the
motor
wiring.
If motor
is dual
voltage
type, BE SURE it is wired
correctly
for your power
supply.
IO. The correct
fusing and wiring
sizing is essential
to proper
motor
operation.
Recommended
fusing
and wire
size data
is in the
mallual.
MAJOR COMPONENTS
/ PIPING
MAJOR
COMPONENTS
AND
WHAT
THEY
DO
NOTICE: Use Teflon
tape supplied
with
the pump
for making
all
threaded
connections
to the pump.
Impeller
and
Jet
Impeller
turns
with
motor
shaft,
causing
water
to fly out from
its
rim by centrifugal
force.
Impeller
rotation
creates
a vacuum
which
pulls in more
water.
Part of the water
is diverted
back
to the jet
where
it passes through
the nozzle
and venturi.
This creates
more
vacuum
to draw in more
water.
In shallow
wells (less than
20 feet deep),
the vacuum
created
at the
pump
is enough
to pull water
to the pump.
Therefore,
the jet as-
sembly
is built into the pump.
Air
Volume
Control
The air volume
control
(AVC)
maintains
the
cushion
of air in
Standard
tanks.
