Bell & Gossett P86101D Series LR Circulators - Manual (Page 2)

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.
DESCRIPTION
The Series LR Circulator features maintenance-free system
liquid lubricated bearings, non-overloading permanent split
capacitor motor with impedance protection and quiet operation.
PUMP APPLICATION
The Series LR Circulator may be used for water circulating
applications in hydronic and solar systems.
This pump is nonsubmersible, for indoor use only. It has not
been investigated, nor is it intended for use in swimming pool
and marine areas.
OPERATIONAL LIMITS
These pumps are designed to pump liquids compatible with
their iron, bronze or stainless steel body constructions.
Maximum Operating Pressure: 150 PSI (10 bars)
Maximum Operating Temperature: 225°F (107°C)
Electrical Rating: 115V, 60Hz, 1Ø
REMOVAL OF PUMP FROM EXISTING SYSTEM FOR REPLACEMENT
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
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.
1. Close the valves on the suction and discharge sides of the
pump. (If no valves have been installed, it may be neces-
sary to drain the system.)
2. Loosen the conduit box cover screw and remove the cover.
3. Disconnect the electrical supply lines to the pump.
4. Remove the flange nuts and bolts. Then remove the pump
from the piping.

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
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: 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: 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: 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.
