Bell & Gossett P76966E Booster Pumps 11/2HP - Manual (Page 2)

ELECTRICAL SAFETY MECHANICAL SAFETY
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, death and/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 sys-
tem components and the release of high temperature fluids.
This can 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, death and/or property damage.
WARNING: EXTREME TEMPERATURE HAZARD
If the pump, motor or piping are operating at extremely
high or low temperature, guarding or insulation is required.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.
THERMAL SAFETY
WARNING: ELECTRICAL GROUNDING HAZARD
Adequate electrical grounding is required for the safe
operation of B&G Pumps. The use of grounded metal con-
duit assures this requirement. If the means of connection to
the supply-connection box (wiring compartment) is other
than grounded metal conduit, ground the pump back to the
service by connecting a copper conductor at least the size
of the circuit conductors supplying the pump to the green
grounding screw provided within the wiring compartment.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect and lockout the power before servicing.
Failure to follow these instructions could result in serious
personal injury or death.
REMOVAL OF THE PUMP FROM EXISTING SYSTEM FOR REPLACEMENT
1. Close the valves on the suction and discharge sides of
the pump. If no valves have been installed, it may be nec-
essary to drain the system.
WARNING: HOT WATER HAZARD
Before draining the system, allow water to cool to
100°F max., open the drain valve (take precautions against
water damage) and leave the drain valve open until servic-
ing is complete. Failure to follow these instructions could
result in serious personal injury, death and/or property
damage.
WARNING: ELECTRICAL SHOCK HAZARD
Be certain the electrical power is not present at the
motor leads before continuing. Failure to follow these in-
structions could result in serious personal injury or death.
2. Loosen the conduit box cover screw and remove the cover.
3. Disconnect the electrical supply lines to the pump
.
WARNING: HIGH PRESSURE HAZARD
Pressure may be present in the pump body. This
pressure can be relieved by loosening the flange bolts and
shifting the pump assembly slightly to allow the pressur-
ized water to escape. Failure to follow these instructions
could result in serious personal injury or death.
4. Remove the flange bolts and nuts and then remove the
pump from the piping.
WARNING: ELECTRICAL SHOCK HAZARD
Electrical connections are to be made by a qualified
electrician in accordance with all applicable codes, ordi-
nances and good practices. Failure to follow these instruc-
tions could result in serious personal injury, death and/or
property damage.
SAFETY REQUIREMENTS
WARNING: ELECTRICAL OVERLOAD HAZARD
Three phase motors must have properly sized
heaters to provide overload and under voltage protection.
Single phase motors have built-in overload protectors.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.

WARNING: HOT WATER HAZARD
When disassembling a gasketed joint, always use a
new gasket upon reassembly. NEVER REUSE OLD GAS-
KETS. Failure to follow these instructions could result in
serious personal injury, death and/or property damage.
WARNING: UNEXPECTED START-UP HAZARD
Single phase motors are equipped with automatic
reset overload protectors. The pump can restart without
warning. Disconnect and lockout power before servicing.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.
