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 release 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 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.
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.

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 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: 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.

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.
4. Remove the flange bolts and remove the pump from the
piping.
PUMP INSTALLATION
PUMP LOCATION
Bell & Gossett Booster Pumps should be installed where there
will be sufficient room for future inspection, maintenance and
service. It is highly recommended that service valves (shut-off)
also be installed on each side of circulator pumps to facilitate
servicing or replacing the pump without draining the system.
IMPORTANT: In closed systems, do not install and operate
Bell & Gossett pumps, 3D valves, suction diffusers, etc., without properly sized safety and control devices. Such devices
include the properly sized and located pressure relief valves,
expansion tanks and pressure, temperature, and flow controls. If the system is not equipped with these devices, consult
the responsible engineer or architect before operating.
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.
Apply torque in even increments to both flange bolts until the
value listed in the table below is reached. Both the suction and
discharge flanges must be torqued in this manner.
PUMP SUPPORTING AND PIPING
Install the suction and discharge flanges on the pipe ends
using Teflon ®* tape sealer or high quality thread sealant.
Minimize strain on the pump by supporting the suction and
discharge piping with pipe hangers near the pump. Line up the
vertical and horizontal piping so that the bolt-holes in both the
pump and pipe flanges are aligned. DO NOT ATTEMPT TO
SPRING THE SUCTION OR DISCHARGE LINES INTO POSITION. THIS MAY RESULT IN UNWANTED STRESS IN THE
PUMP BODY, FLANGE CONNECTIONS AND/OR PIPING. The
code for pressure piping, ANSI B31.1, lists types of supports
for various applications.
Ordinary wire or band hangers are not adequate to maintain
alignment. It is very important to provide strong, rigid support
for the suction and discharge lines.
IMPORTANT: Do not support the pump by its power pack. To
function properly, the motor power pack must not be strained.

OPERATIONAL INSTRUCTIONS
WIRING INSTRUCTIONS
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect and lockout the power before making
electrical connections. Failure to follow these instructions
could result in serious personal injury or death.
SYSTEM PREPARATION1
Prior to pump start up, closed heating and cooling systems
should be flushed with clean water and drained. The system
should then be filled with clean water having a PH between 7
and 9.
1. Remove the screws securing the conduit box cover (wiring
compartment) and lift off the cover. Attach the appropriate
size connector to the hole in the side of the conduit box.
LUBRICATION1
Although the new B&G pumps are test run at the factory, they
must be lubricated thoroughly before being placed in operation. Bell & Gossett supplies a high quality lubricant specifically for this purpose which can be purchased from any B&G
Representative (Part No. L23401). Proper lubrication procedurs are as follows:
1. PUMP BEARINGS – Fill the bearing frame according to the
oiling instructions decal. At the time of installation, add
approximately 1 oz. of B&G #20 weight non-detergent oil.
An SAE 20 (non-detergent) or 10W-30 oil may be substituted.
Re-lubrication is required at the start of each heating season, or every three months for continuous service. Relubricate with 1 teaspoon of oil. More frequent lubrication
may be required under adverse conditions such as high
ambient temperatures. Less frequent lubrication is required
if oil overflows from the reservoir.
2. MOTOR BEARINGS – Lubricate through the two motor oil
cups according to the lubrication decal. At the time of
installation the motor bearings use approx. 12 drops each.
At re-lubrication intervals fill each motor bearing with
approx. 6-8 drops. More or less frequent re-lubrication
may be required depending on the installation conditions.
NOTE: Over-oiling can cause motor mount deterioration and
may cause spillage onto surrounding surfaces. Deteriorated
motor mounts will lead to misalignment and excessive coupler
wear.
2. Using a minimum size 14 AWG copper electrical wire (refer
to your local code for wiring restrictions), wire the motor to
a 115 volt, 60 hertz, single phase power source.

3. Connect the ground wire to the green screw inside the
conduit box.
NOTE: Single phase motors are protected with inherent overheating devices and do not require external overload protection.
NOTE: If a motor with special characteristics is selected, the
electrical rating of the power source must be the same as that
of the motor.
WARNING: ELECTRICAL SHOCK HAZARD
Be certain that all connections are secure and the
conduit box cover is closed before electrical power is connected. Failure to follow these instructions could result in
serious personal injury, death and/or property damage.
CAUTION: SEAL DAMAGE HAZARD
Do not run the pump dry – seal damage may occur.
Failure to follow these instructions could result in moderate
personal injury and/or property damage.
PRIMING AND STARTING
Do not run B&G circulator pumps dry. Before starting, the
pump must be filled with water. Air should be vented from the
system by means of a system air vent or by an alternate method.
