Xylem AC8584C Series HSCS Base Mounted Centrifugal Pumps - Manual (Page 4)

PUMP LOCA TION
Locate the pump so ther e is sufficient room for inspection, main-
tenance and service. If the use of a hoist or tackle is needed,
allow ample head room.
If lifting base pump is required, use a nylon string, chain, or
wire rope, hitch around both bearing supports. If lifting of the
entire pump is required, do so with slings placed under the
base rails as shown.
Care must be taken to size equipment for unbalanced loads
which may exist if the motor is not mounted on the base at the
time of lifting. Motor may or may not be mounted at the factory.
Pump, base, and driver assemblies where the base length
exceeds 100 inches may not be safe to lift as a complete
assembly. Damage to the baseplate may occur. If the driver has
been mounted on the baseplate at the factory, it is safe to lift
the entire assembly. If the driver has not been mounted at the
factory and the overall baseplate length exceeds 100 inches,
do not lift the entire assembly consisting of a pump, base, and
driver. Instead, lift the pump and baseplate to its final location
without the driver. Then mount the driver.
The best pump location for sound and vibration absorption is
on a concrete floor with subsoil underneath. If the pump loca-
tion is overhead, special precautions should be undertaken to
reduce possible sound transmission. Consult a sound specialist.
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 Suction Head Required (NPSHR), as stated by the
pump performance curve. See page 9 for more details on
proper suction piping installation.

ADDITIONAL SAFETY REQUIREMENTS:
ELECTRICAL SAFETY:
THERMAL SAFETY:
MECHANICAL SAFETY:
WARNING: Electrical Shock Hazard
Electrical connections to be made by a qualified
electrician in accordance with all applicable codes, ordi-
nances, and good practices. Failure to follow these
instructions could result in serious personal injury or death,
or property damage.
W ARNING: Electrical Overload Hazard
Thr ee phase motors must have properly sized
heaters to provide overload and undervoltage protection.
Single phase motors have built-in overload protectors.
Failure to follow these instructions could result in serious
personal injury or death, or property damage.
W ARNING: Extreme Temperature Hazard
If pump, motor , or piping are operating at extremely
high or low temperatures, guarding or insulation is re-
quired. Failure to follow these instructions could result in
serious personal injury or death, or property damage.
W ARNING: Unexpected Startup Hazard
Disconnect and lockout power befor e servicing.
Failure to follow these instructions could result in serious
personal injury or death, or property damage.
W ARNING: Excessive System Pressure Hazard
The maximum working pr essure of the pump is listed
on the nameplate, do not exceed this pressure. Do not use
air to hydrotest pump. Failure to follow these instructions
could result in serious personal injury or death, or property
damage.
W ARNING: Excessive Pressure Hazard
Volumetric Expansion
The heating of water and other fluids causes volumetric
expansion. The associated forces may cause failure of sys-
tem components and release of high temperature fluids.
This will be prevented by installing properly sized and
located compression tanks and pressure relief valves.
Failure to follow these instructions could result in serious
personal injury or death, or property damage.
W ARNING: Falling Objects Hazard
Eyebolts or lifting lugs, if pr ovided, are for lifting only
the components to which they are attached. Failure to
follow these instructions could result in serious personal
injury or death, or property damage.
