INSTALLING MOTOR ON PUMP ENDS
If you purchased a pump end without a factory supplied
motor, you will need to install a motor to the pump end.
A 56C Frame keyed shaft motor must be used with the
BT4 pump ends. The table below outlines the minimum
motor rating for your pump.

ATTACHING MOTOR TO PUMP END
1. If you are installing a three-phase motor onto the
pump end, the motor rotation must be checked
prior to connecting it to the pump. Instantaneously
energize the motor to check for counterclockwise
rotation as viewed from the pump end, or shaft end,
of the motor. The proper rotation is also indicated
by the rotation arrow label on the pump bracket. If
it is not correct, reverse the rotation as instructed
on the motor label. Failure to check rotation prior
to assembly to the pump could result in pump
damage if the rotation is wrong when the completed
assembly is energized.

2. Apply one drop of Loc-Tite 242 to each set screw
and install both of them into the shaft coupling.
Screw them into the coupling to the point where
they just protrude into the ID of the coupling. This
position will allow you to align the shaft keyway with
the set screws, but still allow the shaft to slide into
the coupling ID.
3. Position the motor up to the pump bracket and slide
into position after lining up the shaft adapter keyway
with the coupling set screws.
4. Fasten the motor to the pump bracket with the
four provided bolts, lock washers, and nuts. Lock
washers should be located under the nut, and not
under the bolt head. Tighten to 115 in-lbs torque.
5. Properly position the coupling by inserting a flat
bladed screw driver between the pump bracket and
the coupling. Pry the coupling all the way toward the
motor with the screw driver.
6. Tighten the set screws to 75 in-lbs with a 5/32"
Allen wrench, while holding the coupling in position
with the flat bladed screw driver.
OPERATION
RATINGS
C A U T I O N
Maximum operating pressure is 500 psi.
Maximum suction pressure is 75 psi. Maximum water
temperature is 120 °F. Consult factory to pump liquids
other than water. Avoid pumping abrasive or sandy
water. Do not run pump dry.
PRIMING
Never run the pump dry. To prime (fill with liquid) fill the
suction pipe, pump, and discharge piping completely
with water. A foot valve is required in all installations
where the pump is required to draw the water from a
source below itself to prevent the priming liquid from
draining out of the pump. A typical booster installation
will be supplied by either a tank, or a pressurized water
source, creating what is known as a flooded suction
condition. A foot valve is not needed in flooded suction
installations.
If the pump's installation will require frequent re-priming
of the pump, it may be useful to add a capped "Priming
T" to the suction line piping. This allows easy re-priming
without removing or disassembling the rest of the
system plumbing.
W A R N I N G
HAZARDOUS PRESSURE: Do not run
pumps against a closed discharge, or at a system
operating pressure above what is mentioned by the
pump manufacturer.
STARTING
Close all system outlets, then slightly crack one system
outlet to allow excess air to bleed out of the system.
Start the pump. Gradually, but immediately, begin
opening the discharge valve to half open. If after a few
minutes of running you do not get water, repeat priming
process (the pump may be locked by excess air that is
