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 in-
structions could result in serious personal injury or death,
or property damage.
WARNING: Electrical Overload Hazard
Three 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.
WARNING: 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 pr
operty damage.
WARNING: Unexpected Startup Hazard
Disconnect and lockout power before servicing.
Failure to follow these instructions could result in serious
personal injury or death, or property damage.

ARNING: Excessive System Pressure Hazard
The maximum working pressure of the pump is listed
on the nameplate, do not exceed this pressure. Failure to
follow these instructions could r
esult in serious personal
injury or death, or property damage.
WARNING: Excessive Pr
essure Hazard
Volumetric Expansion
The heating of water and other fluids causes volumetric
expansion. The associated forces may cause failur
e 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.
PUMP LOCATION
Locate the pump so there 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 of the entire pump is required, do so with slings placed
under the base rails as shown.
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.
IMPORTANT
Do not install and operate Bell & Gossett Pumps, 3D Valves,
Suction Diffusers, etc., in closed systems unless the system is
constructed with properly sized safety devices and control
devices. Such devices include the use of properly sized and
located pressure relief valves, compression tanks, pressure con-
trols, temperature controls, and flow controls as appropriate. If
the system does not include these devices, consult the respon-
sible engineer or architect before making pumps operational.

WARNING: Fall Objects 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, or property damage.
