Current unbalance should not exceed
5%. If the unbalance cannot be cor-
rected by rolling leads, the source of
the unbalance must be located and
corrected. If, on the three possible
hookups, the leg farthest from the av-
erage stays on the same power lead,
most of the unbalance is coming from
the power source.
Contact your local power company to
resolve the imbalance.
5.0 STARTING
THE PUMP
5.1 Install a Valve
and Run the Pump To
Clear the Water
On a new well - Install a
ball or globe valve on the
pump discharge line and

open, pump the well
until the water begins to run clear.
Open the valve slowly to check ow
and when the water runs clear turn
the pump Power Off.
Remove the ball or globe valve and
connect the pump discharge to the
house plumbing, pressure tank and
switch. Turn Power On. Run a few
cycles through the tank to rinse it out
and to verify proper pump and switch
operation. Use this time to check all
ttings for leaks.
CAUTION: If the well has a high
static level, please see next section
for important pump protection
information.
5.2 Throttling A
High Static
Level Well To
Prevent Upthrust
Any well with a high static water level
may allow the pump to operate off
the curve to the right or outside the
“Recommended Range” shown on
the pump curve. We recommend
using a “Dole” ow restrictor or
throttling with a ball valve to prevent
upthrust damage to the pump and
motor. The maximum ow must be
restricted to be within the pumps
recommended operating range. If
you use a ball valve, set it, remove the
handle, tape the handle to the pipe,
and tag the valve with a note saying,
“Do not open this valve or pump may
be damaged”. The easiest way to “set”
the ow is to ll a 5 gallon bucket and
time how long it takes to produce 5
gallons. Calculate the ow in gpm
based on this value. As the water
level drops in the well the ow will
be reduced due to increased head
and the valve will not interfere with
performance.
6.0 PAPERWORK
and IOM
Please give this lled-in IOM and your
business card to the owner.
A sticker with your name and phone
number on the tank or control box is
a great sales tool for future business!
We now provide an extra pump label
which you can afx to the IOM, put
on a 3-wire control box or locate near
the tank and pressure switch for future
pump identication.
Hazardous pressure can
cause personal injury
or property damage.
