Unpacking
When unpacking the unit inspect carefully for any damage that may have occurred during transit. Check for loose, damaged, or
missing parts. Do not attempt to assemble or operate pump if any parts are missing or damaged.
General Safety Information
1. Know the pump application, limitations and potential hazards.
WARNING: Pump should only be used with liquids compatible with pump component materials. Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable and/or explosive atmospheres.
CAUTION: These pumps have been evaluated for use with water only. For your protection always wear proper clothing, eye
protection, etc. in case of any malfunction. For proper handling techniques and precautions, contact your supplier,
insurance company and local agencies (fire dept., etc.). Failure to comply with this warning may result in personal injury and/
or property damage.
2. Ensure that the power source conforms to the requirements of your equipment.
3. Disconnect power before servicing. If the power disconnect is out of sight, lock in the open position and tag it to prevent
unexpected application of power. Failure to do so may result in a fatal electric shock!
4. Release all pressure within the system before servicing any component.
5. Drain liquids from the system before servicing.
6. Personal Safety:
b. Keep work area clean, uncluttered, and properly lighted. Replace all unused tools and equipment.
c. Keep visitors at a safe distance from the work area.
d. Make workshop childproof with padlocks, master switches and by removing starter keys.
a. Wear safety glasses at all times when working with pumps.
7. The motor is designed to be used in a clean dry location with access to an adequate supply of cooling air.
8. When wiring an electrically driven pump follow all electrical and safety codes.
9. Single phase motors: All units are supplied with 115 volt, single phase motors.
10. All wiring should be performed by a qualified electrician.
WARNING: Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface or in water.
Australia
This pump must be installed in accordance with AS3500
InstallationÉ
The pump should not be used in flammable or explosive atmospheres. For installations where property damage might result from an
inoperative or leaking pump, provide a drip pan to collect leakage. Failure to follow any warning can result in personal injury and/or
property damage.
1. Support the piping independently of the pump. B&G pumps are lubricated by the pumped fluid. How they are mounted and
the condition of the water in the system are important. THOROUGHLY CLEAN and FLUSH the system before installing the pump. If
the fluid contains a high level of dissolved solids such as dirt, sediment, or products of corrosion, a strainer and/or filter should be
installed at least 12” before the inlet to the pump.
Mounting
For installation purposes the arrows on the pump housing indicate the
direction of water flow through the pump. Check to make sure the pump
is adequately supported and that neither the pump or the piping is
stressed. Install the pump at a point closest to the highest static pressure
point, but above the absolute lowest point in the system to avoid dirt and
sediment build-up. If required by application and code, install a safety
relief valve to protect against over temperature and pressure. Do not
mount with the motor above the impeller. This can cause the pump to run
dry leading to premature failure of the pump which voids the warranty.

Electrical
These instructions must be followed to reduce risk of electrical shock. All work should be performed by a qualified electrician and in
accordance with the current national and local electrical codes and regulations. Consult the nameplate for electrical data. The
motor is protected. Make certain that a properly sized circuit is available. Wire size should be based on the current
carrying (amp) capacity of the conductor. The pump must be grounded in accordance with the current national and local codes.
Ground wire should be copper with a current capacity at least equal to that of the wire carrying power to the pump. Observe all
minimum code requirements for your jurisdiction. Isolation valves are recommended for both sides of the pump. Valves should be
positioned to avoid leakage onto the motor and electrical compartment. All elbows, tees, and sharp bends in the piping should be
installed sufficiently upstream or downstream of the suction and discharge ports. Avoid welding or soldering close to the pump,
