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.
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
required.
Failure to follow these instructions could result in serious
personal injury or death, or property 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.
WARNING: 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 result in serious
personal injury or death, or property damage.
WARNING: Excessive Pressure Hazard
Volumetric Expansion
The heating of water and other fluids causes volumetric
expansion. The associated forces may cause failure of
system 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,
maintenance 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 pump as shown in Figure 4.
The best pump location for sound and vibration absorption is
on a concrete floor with sub soil underneath. If the pump
location is overhead, special precautions should be under-
taken 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) exceeds the Net
Positive Suction Head Required (NPSHR), as stated by the
pump performance curve.
WARNING: Falling Objects Hazard
Eyebolts or lifting lugs, if provided, 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.

IMPORTANT
Do not install and operate your pump 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 controls, temperature
controls, and flow controls as appropriate. If the system
does not include these devices, consult the responsible
engineer or architect before making pumps active.
