SAFETY INSTRUCTIONS
TO AVOID SERIOUS OR FATAL PERSONAL INJURY
OR MAJOR PROPERTY DAMAGE, READ AND
FOLLOW ALL SAFETY INSTRUCTIONS IN MANUAL
AND ON PUMP.
THIS MANUAL IS INTENDED TO ASSIST IN THE
INSTALLATION AND OPERATION OF THIS UNIT
AND MUST BE KEPT WITH THE PUMP.
This is a SAFETY ALERT SYMBOL.
When you see this symbol on the pump
or in the manual, look for one of the
following signal words and be alert
to the potential for personal injury or
property damage.
Warns of hazards that WILL cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause per-
sonal injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS
AND WARNINGS PRIOR TO PERFORMING ANY
WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
UNIT NOT DESIGNED FOR USE
WITH HAZARDOUS LIQUIDS OR
FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
• Provide adequate space and ventilation around unit for
service and for motor cooling.
• Protect the pump and piping from freezing tempera-
tures.
• The unit MUST be securely affixed to a level metal
base foundation, adequate to absorb vibration and pro-
vide permanent, rigid support for the pump and motor
assembly. See the “ENGINEERING DATA” section of
this manual for specific model weights and pump base
dimensions.
NOTICE: DO NOT DRAW PIPING INTO PLACE BY
FORCING THE PUMP DISCHARGE
CONNECTIONS.
• Discharge piping should be no smaller than the
respective pump opening and should be kept as short
as possible, avoiding unnecessary fittings to minimize
friction losses.
DANGER
WARNING
CAUTION
WARNING
Hazardous fluids
can cause fire,
burns or death.
NOTICE: PIPING MUST BE INDEPENDENTLY SUP-
PORTED AND NOT PLACE ANY PIPING
LOADS ON THE PUMP.
• Insure that the size and minimum liquid submergence,
over the suction inlet, is sufficient to prevent air from
entering through a suction vortex. See typical suction
piping Figures 1 and .
• Install a discharge check valve, suitable to handle the
flow and liquids, to prevent backflow.
• Install an appropriately sized gate valve, AFTER the
discharge valve, to regulate the pump capacity, for
pump inspection and for maintenance.
• When a pipe increaser is required, install between the
check valve and the pump discharge.
• When the pump is purchased less motor, the pump will
be supplied with a motor assembly shim positioned
between the motor adapter and the coupling.
• To assemble the motor to the pump remove the plastic
shipping straps, the  stainless steel coupling guard
halves, and the expanded polyurethane.
• Insure that the motor assembly shim is properly posi-
tioned between the coupling and the motor adapter. If
the motor assembly shim is not available, a 0.03"
(5 mm) shim may be used to locate the pump shaft
assembly and to set the correct height.
• For motor frame sizes 13TC and larger, attach the
motor adapter flange to the motor using  hex cap
screws. Torque to values shown in the
“ENGINEERING DATA” section of this manual.
• Loosen the  coupling socket head screws enough to
provide an adequate opening in the coupling to receive
the motor shaft.
• With an adequately sized crane, carefully lower the
motor assembly onto the pump motor adapter and
into the coupling. Secure the  motor hex cap screws,
torquing to the value provided in the
“ENGINEERING DATA” section of this manual.
• Torque the  coupling socket head screws to the value
provided in “ENGINEERING DATA” section of this
manual.
• Remove the motor assembly shim and retain for future
use.
• Install the  coupling guard halves.
