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 chemical
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:
a. Wear safety glasses at all times when working with pumps.
b. Wear a face shield and proper apparel when pumping hazardous chemicals.
c. Keep work area clean, uncluttered, and properly lighted. Replace all unused tools and equipment.
d. Keep visitors at a safe distance from the work area.
e. Make workshop childproof with padlocks, master switches and by removing starter keys.
7. The motor is designed to be used in a clean dry location with access to an adequate supply of cooling air. Ambient
temperature around the motor should not exceed 122ºF (50ºC). For outdoor installations motor must be protected by
a cover that does not block airflow to and around the motor. This unit is not able to be submersed in water.
8. When wiring an electrically driven pump follow all electrical and safety codes, as well as the most recent United
States National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
Installation
The pump should not be used in flammable or explosive atmospheres. In order to safely use this product,
familiarize yourself with this pump and also with the liquid (chemical, etc.) that is going to be pumped through the unit.
This pump is not suitable for many liquids. For installations where property damage might result from an inoperative
or leaking pump due to power outages, discharge line blockage, or any other reason, a backup system(s) should be
used. Failure to follow any warning can result in personal injury and/or property damage.
1. Locate pump as close to the fluid source as possible, thus making the suction line as short and direct as possible.
The unit should be placed where the motor and electrical components are protected from the weather and humidity.
2. Attach piping suction line to suction inlet and piping discharge line to discharge outlet. Avoid using looped section
of pipe or fittings which might permit air to compromise airtight pipe connections. IMPORTANT: If plastic or fabric
hose is used for the suction piping it should be of a reinforced type so as not to collapse under suction.
3. Support the piping independently of the pump.
4. Laing 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.

9. Single phase motors: All units are supplied with 115 volt, single phase motors (unless otherwise noted) and
provided with a 6 foot 3 wire flexible cord with a 3 prong grounded plug suitable for a standard grounded type 115 volt
receptacle. Where a 2 prong wall receptacle is encountered, it must be replaced with a properly grounded 3 prong
receptacle installed in accordance with the National Electrical Code, local codes and ordinances. To ensure a proper
ground, the grounding means must be tested by a qualified electrician.
10. Use only 3 wire extension cords that have 3 prong grounding type plugs and 3 pole receptacles that accept the
equipment plug.
11. All wiring should be performed by a qualified electrician.
12. Protect electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Replace or
repair damaged or worn cords immediately.
Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface or in water.
U.L. Caution
This pump has been tested using water only.
Its suitability for use with liquids other than water is the end user’s responsibility.
Australia
