INSTRUCTIONS
(Continued)
6. Disconnect
electrical
power
source
before
installing
or
working
on pump.
7. Ground
pump
with a ground
wire run from grounding
lug on motor
to a grounded
lead in the service
panel.
8. Line voltage
and frequency
of electrical
power
supply
must agree with motor
nameplate.
9. Use of fuses or wire smaller
than size recommended
in
owner's
manual can cause overheating,
possible
fires,
and will void warranty.

MAJOR COMPONENTS
AND
WHAT
THEY
DO
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 di-
verted
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
cre-
ated
at the pump
is enough
to pull water
to the pump.
Therefore,
for shallow
well use the jet is built into the pump.
Pre-Charged
Tank
The tank serves
two
functions.
It provides
a reservoir
of
water
under
pressure
and
maintains
a cushion
of air pres-
sure
to prevent
pipe
hammering
and possible
damage
to
plumbing
components.
When
water
is drawn
off through
the house
fixtures,
the pressure
in the tank is lowered
and
the pump
starts.
Pressure
Switch
The
pressure
switch
provides
for automatic
operation.
Pump starts
when
pressure
drops
to 40 pounds
and stops
when
pressure
reaches
60 pounds.
Check Valve or Foot Valve
This pump
is equipped
with
a built-in
check valve. Install a
check valve as close
to well
as possible
on well point
in-
stallations.
A foot valve must be installed
in the well on dug
or cased wells. See Figures 2A and 2B, Page 4. For long hor-
izontal pipe runs, install check
valve as close to well as pos-
sible (all types of wells).
