PUMP LOCATION
Locate the pump so there is sufficient room for inspection,
maintenance and service. If the use of a hoist or tackle is
needed, allow ample head room.
WARNING: Falling Object Hazard
Eyebolts or lifting lugs if provided are for lifting only
the components to which they are attached. Failure to fol-
low these instructions could result in serious personal injury
or death, and property damage.
If lifting of the entire pump is required, do so with slings placed
around the pump assembly as shown in Fig. 2A. Or if your
pump configuration looks like Fig. 2B, connect a nylon sling,
wire rope or chain to the brace ribs on the motor adapter. Use
one sling for each rib. Attach all slings together at least 2 ft,
above the top of the pump.
CAUTION: Some pumps may have the center of
gravity at, or slightly above, the lift point. This may
create a tipping hazard. To avoid this hazard securely bind
the lifting lines to the side of the motor using a strap or
chain wrapped securely around the top of the motor. Unit
should only be lifted vertically. Failure to follow these
instructions could result in serious personal injury or
death, and property damage.

Special precautions to avoid sound and vibration transmission
should be taken if the pump is to be located near a noise sen-
sitive area, a sound specialist should be consulted.
If the pump is not on a closed system, it should be placed as
near as possible to the source of the liquid supply, and located
to permit installation with the fewest number of bends or
elbows in the suction pipe.
The installation must be evaluated to determine that the Net
Positive Suction Head Available (NPSHA) meets or exceeds
the Net Positive Head Required (NPSHR), as stated by the
pump performance curve.
