SAFETY REQUIREMENTS
MECHANICAL SAFETY
ELECTRICAL 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: ELECTRICAL SHOCK HAZARD
Electrical connections are to be made by a qualified
electrician in accordance with all applicable codes,
ordinances and good practices. 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
system components and the release of high temperature
fluids. This can be prevented by installing properly sized
and located expansion tanks and pressure relief valves.
Failure to follow these instructions could result in serious
personal injury, death and/or property damage.
WARNING: ELECTRICAL GROUNDING HAZARD
Adequate electrical grounding is required for the safe
operation of B&G Pumps. The use of grounded metal
conduit 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. Use a copper conductor at least the size of
the circuit connectors supplying the pump. Connect the
ground wire to the green grounding screw in the wiring
compartment. Failure to follow these instructions could
result in serious personal injury death and/or property
damage.
THERMAL SAFETY
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.
WARNING: RISK OF ELECTRIC SHOCK
Do not install this pump in swimming pool or marine
areas. Failure to follow these instructions could result in
serious personal injury, death and/or property damage.
REMOVAL OF PUMP FROM EXISTING SYSTEM FOR REPLACEMENT
2
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect and lockout the power before servicing.
Failure to follow these instructions could result in serious
personal injury or death.
WARNING: ELECTRICAL SHOCK HAZARD
Be certain the electrical power is not present at the
motor leads before continuing. Failure to follow these
instructions could result in serious personal injury or death
1. Close the valves on the suction and discharge sides of the
pump. (If no valves have been installed, it may be necessary to drain the system.)
2. Loosen the conduit box cover screw and remove the cover.
WARNING: HOT WATER HAZARD
Before draining the system, allow water to cool to at
least 100°F, open the drain valve (take precautions against
water damage) and leave the drain valve open until
servicing is complete. Failure to follow these instructions
could result in serious personal injury, death and/or
property damage.
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 pressurized
water to escape. Failure to follow these instructions could
result in serious personal injury or death.
3. Disconnect the electrical supply lines to the pump.
4. Remove the flange nuts and bolts. Then remove the pump
from the piping.
PUMP INSTALLATION
Locate the pump so there is sufficient room for inspection,
maintenance and service. Bell & Gossett recommends the
installation of service valves on the suction and discharge of
all circulators to facilitate servicing or replacement of the
circulator without draining the system.
CAUTION: The use of Teflon ®*impregnated pipe
compound and Teflon® tape on pipe threads provides lubricity which can lead to overtightening and breakage. Do not overtighten. Failure to follow this instruction
can result in moderate personal injury from hot water
and/or property damage.
Apply torque in even increments to both flange bolts until a
value of 115 in-lbs. is reached. Both the suction and discharge
flange bolts must be torqued in this manner.
WARNING: WATER LEAKAGE HAZARD
To prevent leakage, make certain that the flange bolts
or ring nuts have been adequately tightened and that the
solder connections do not leak. Failure to follow these
instructions could result in serious personal injury, death
and/or property damage.
MODE OF DISCHARGE
Install suction and discharge flanges or union connectors on
the pipe ends. The use of Teflon® tape sealer or a high quality
thread sealant is recommended.
Be sure to minimize any pipe-strain on the pump. Support the
suction and discharge piping by the use of pipe hangers near
the pump. Line up the vertical and horizontal piping so that the
bolt-holes in the pump flanges match the bolt-holes in the
pipe flanges. If union connections are used, line up the pump
threads with union tail pieces. DO NOT ATTEMPT TO SPRING
THE SUCTION OR DISCHARGE LINES IN POSITION. THIS
MAY RESULT IN UNWANTED STRESS IN THE PUMP BODY,
FLANGE CONNECTIONS AND PIPING. The code for Pressure
Piping (ANSI B31.1) lists many types of supports available for
various applications.
Bell & Gossett flange gaskets must be installed between the
pump body flanges and the suction and discharge pipe
flanges. Use 7/16" diameter x 11/2" long cap screw and matching nut to connect the pump to the flanges.
WARNING: HOT WATER HAZARD
When disassembling a gasketed joint, always use a
new gasket upon reassembly. NEVER RE-USE OLD
GASKETS. Failure to follow these instructions could result
in serious personal injury, death and/or property damage.
WARNING: HOT WATER HAZARD
Make sure that each flange gasket remains seated in
the flange groove during and after installation. Failure to
follow these instructions could result in serious personal
injury, death and/or property damage.
The Series LR Circulator can be installed to discharge up or
down, horizontally, left or right, but the motor shaft must
remain in the horizontal position, the arrow on the body must
point in the direction of the flow, the conduit box must be positioned on the top or to the side of the motor housing (see figure 2). If the conduit box position must be changed, it is best
to do so before installation. However, if the pump is already
installed, see the section titled “REMOVAL OF PUMP FROM
EXISTING SYSTEM FOR REPLACEMENT” before proceeding.
CAUTION: Make sure the power is turned off before
placing anything inside the discharge opening to
move the impeller. Failure to follow these instructions could
result in serious personal injury, death and/or property
damage.
TO CHANGE THE CONDUIT POSITION
1. Remove the four (4) 1/4-20 Allen screws (3/16 wrench) while
supporting the motor assembly.
2. Remove the motor assembly from the pump body and
rotate it to the desired position (see figure 2).
3. Replace the Allen screws and tighten evenly in a diagonal
method to 60 in-lbs.
4. Check to see that the impeller turns freely. Insert your finger
in the discharge port of the pump body (the arrow on the
pump body points in the direction of the discharge) until
you can feel the impeller and rotate it with your
fingertip. If the impeller does not turn easily, repeat the disassembly/reassembly process.
