IMPORTANT PRE-INSTALLATION INFORMATION
Hazardous voltage can shock, burn or cause
death. All electrical work must be performed
by a qualied technician. Always follow the
local applicable electrical code.
The pump must be connected to a dedicated
electrical circuit protected by a properly sized
circuit breaker or fuses. Install a disconnect
Control Panel where required by the local
code.
Code questions should be directed to your electrical inspector.
See Chart 1 for specific information.
Always disconnect the power source before
installing or servicing the pump. This motors
come with an automatic thermal overload
protection, this feature may allow an
overheated pump to restart suddenly.
Water and electricity can be dangerous if
certain precautions are not adhered to.
This pump is designed to operate in a safe
way in a water environment; however,
improper use and installation can result in
personal harm from electrical shock. Please
pay attention to the following warnings.
Never touch this pump, when it is touching
water, in water, or even in a moist environ-
ment. Always unplug (disconnect the electric-
ity) when working on or installing the unit.
Do not use this pump with ammable or
explosive liquids such as oil, gasoline,
kerosene, ethanol, etc. Using this pump
with or near ammable liquids can cause an
explosion or re, resulting in property damage,
serious personal injury and/or death.
Pumping any of the above mentioned liquids
voids the warranty. Always make sure that this
pump is pumping liquid with same composi-
tion as water.

1. GENERAL INFORMATION
1.1. Read this Instruction Manual thoroughly prior to any work.
Work should be undertaken by qualified persons only.
ATTENTION!
Important information for installers of this
equipment!
This equipment is intended for installation by technically qualified
personnel. Failure to install it in compliance with national and
local electrical codes, and with motor suppliers recommenda-
tions, may result in electrical shock or fire hazard, unsatisfac-
tory performance, and equipment failure. Installation information
is available from pump manufacturers and directly from motor
suppliers. Retain this information sheet with the equipment for
future reference.
WARNING
Serious or fatal electrical shock may result from failure to
connect the motor, control enclosures, metal plumbing, and all
other metal near the motor or cable, to the power supply ground
terminal using wire no smaller than motor cable wires. To reduce
risk of electrical shock, disconnect power before working on or
around the water system.
1. LOCATION
The pump should be installed in a dry, accessible place not
subject to freezing temperatures. If installed in a pump pit or
other location subject to dampness, proper ventilation must be
provided to avoid moisture damage to the electrical equipment.
2. PIPING
Galvanized steel or plastic pipe is recommended. If copper or
other dis-similar metal piping is used, a di-electric union or
bushing is recommended where the piping is connected to the
pump body. The pipe used should be cleaned and free of scale.
Ream ends of pipe to remove burrs. Check threads to see that
they are clean and not damaged. Horizontal runs of suction
pipe must slope upwards from the well to the pump to avoid air
pockets in the line which will make it difficult, if not impossible, to
prime the pump. The recommended slope is one inch in ten feet.
If pump must be offset an appreciable distance from the well,
the size of horizontal pipe should be increased to reduce
friction losses.
If using di-electric bushing, hand start bushing into female end of
pump housing (or other female connection) first. Use a six-sided
socket to tighten the bushing.
The bushing should be fully inserted into the female connec-
tion. After the male end of the bushing is fully installed, hand
start pipe (or other male connection) into the female end of the
bushing.Failuretofollowtheseguidelinesmaydamagethebushing.
Caution should be taken to not cross-thread the bushing.
3. FLUSHING
If the pump discharge line is connected to pressure tank or
house service, disconnect it and flush and clean the system by
* Time delay fuses and circuit breakers (Single Phase).
For distances of 100 feet and over from meter to motor, larger
wire than shown may be required.
5. MOTORS
Motors are equipped with sealed ball bearings and require little
attention.
If motor repeatedly stops, cools off, and starts again, the cause
or trouble must be located and corrected. Do not cover motor
with canvas or other material that may interfere with proper air
circulation and cause over-heating.
CAUTION
!
temporarily wasting the water outdoors or to drain. The pump
should be operated until the water runs clear, without sand, mud
or rust.
This procedure will eliminate the danger of pumping dirty water
into the pressure tank and home appliances. When water runs
clear, re-connect discharge line to tank and service.
4. WIRING (Use copper conductors only)
Be certain that wire and fuses of correct size are installed. Be
certain the phase, voltage, and cycles of the supply circuit are
the same as that shown on the motor name plate.
It is strongly recommended that a separate electric line, well pro-
tected against fire, be run from electrical service to the pump,
with a fused switch box at the pump.
In the event of fire, this precaution will permit continuous opera-
tion of your pumping system. For added safety, the pump and
motor should be properly grounded to the well casing or to a
separate ground rod driven eight feet into the ground.
NOTE: For proper fuse, circuit breaker and wire sizes in your
area, follow local codes. Otherwise:

A shallow well system should not be installed where total suction
lift exceeds 25 feet at sea level. Suction lift must be reduced at
the rate of approximately 1 foot per 1000 feet at elevation. Total
suction lift consists of the vertical distance from the water level
when pumping to the pump plus losses due to friction in the pipe
line. The volume of water delivered decreases with an increased
suction lift.
Drilled, bored or dug wells may employ an arrangement as in
Figure 1. Driven wells and sandpoints employ the configuration
in Figure 2.
1. a) Install a foot valve on the bottom of the suction line and
place it 5 to 10 feet below the draw down level, that is, the level
of the water when the unit is pumping its rated capacity. It should
be far enough from the bottom of the well to avoid pumping sand
and mud. (Figure 1)
b) On driven well installation, install a spring dog- check valve
on the vertical pipe at least five feet above the well point, or in-
stall a horizontal check valve in the suction line near the pump.
(Figure 2)
2. Check the foot valve, see that it seats properly and that no
obstruction prevents its opening or closing. A leaky foot valve
may cause excessive cycling (motor starts and stops).
3. Lower first length of suction pipe, with attached foot valve into
the well, fill pipe with clean water. If water recedes a leak is in-
dicated. If no leaks occurs, assemble the remaining section(s) of
pipe and check again for leaks.
4. Install the well seal at the top of the well casing and tighten
well seal bolts. (Figure 1)
5. Install a tee at top of suction pipe, with a plug in the top open-
ing, and connect through a union to the female thread in the
pump body.

6. Connect pump discharge to pressure tank, and pressure tank
to house plumbing.
7. After piping is completed and motor is properly wired, remove
the priming plug on top of pump and fill pump with clean water.
Allow time for air in the system to escape, and refill pump if nec-
essary before replacing the priming plug. Start motor and the
unit should operate.
If it does not, it may be necessary to reprime.
8. When unit has built up to maximum pressure, and has auto-
matically stopped, check all piping both suction and discharge
lines for leaks, as they will be under pressure.
NOTE: If the unit is to be used with a vacuum type air volume
control where the source of supply is on a level with the pump
or above it (artesian well, pond, cistern or shallow well with less
than five feet lift) a valve should be installed in the suction line
that may be partially closed to cause the pump to operate under
a moderate suction lift of 8-10 ft. to insure correct operation of
the air volume control which is operated by vacuum.
