General Safety Information
Know the pump application, limitations and potential hazards.
WARNING: PUMP SHOULD ONLY BE USED WITH LIQUIDS COMPATIBLE WITH PUMP COMPONENT MATERIALS. WHEN PUMPING
HAZARDOUS OR DANGEROUS MATERIALS, USE ONLY IN ROOM OR AREA DESIGNATED FOR THAT PURPOSE. FOR YOUR
PROTECTION, ALWAYS WEAR PROPER CLOTHING, EYE PROTECTION, ETC. IN CASE OF ANY MALFUNCTION. FOR PROPER
HANDLING TECHNIQUES AND CAUTIONS, CONTACT YOUR CHEMICAL SUPPLIER, INSURANCE COMPANY AND LOCAL AGENCIES
(FIRE DEPT., ETC.). FAILURE TO COMPLY WITH THIS WARNING COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY
Make certain that the power source conforms to the requirements of your equipment.
Provide adequate protection and guarding around moving parts.
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 could result in fatal electrical shock!
Release all pressure within the system before servicing any component.
Drain liquids from the system before servicing.
Secure the discharge line before starting the pump. An unsecured discharge line will whip, possibly
causing personal injury and/or property damage.
Check hoses for weak or worn condition before each use. Make certain that all connections are secure.
Periodically inspect pump and system components. Perform routine maintenance as required (see
10. Provide a means of pressure relief for pumps whose discharge line can be shut off or obstructed.
11. Personal Safety:
Wear safety glasses at all times when working with pumps.
Wear a face shield and proper apparel when pumping hazardous chemicals.
Keep work area clean, uncluttered, and properly lighted; replace all unused tools and equipment.
Keep visitors at a safe distance from the work area.
Make workshop child proof - with padlocks, master switches, and by removing starter keys.
12. This unit is not waterproof and is not intended to be used in showers, saunas, or other potentially wet
locations. 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 1040F (400C). For outdoor
installations, motor must be protected by a cover that does not block airflow to and around the motor. This
unit is not weatherproof nor is it able to be submersed in water.
13. When wiring an electrically driven pump, follow all electrical and safety codes, as well as the most recent
National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
14. WARNING: RISK OF ELECTRIC SHOCK! The motors on Models 2P123, 2P124, 2P125, 2P375, 2P376, &
2P377 are for use with 208-220/440 (3-phase) power. These units are for permanent installation using a
power supply with a ground.
To reduce the risk of electric shock, electric motor must be adequately grounded to a metal raceway
system, or by suing a separate grounding wire connected to bare metal on the motor frame, or to the
grounding screw located inside motor terminal box, or by other suitable means. Refer to the most recent
National Electrical Code (NEC) Article 250 (Grounding) for additional information. ALL WIRING SHOULD
BE DONE BY A QUALIFIED ELECTRICIAN.
15. WARNING: RISK OF ELECTRIC SHOCK! This equipment (Models 2P121, 2P122, 2P373 & 2P374) can
be used for either 115V (single phase) or 230V (single phase). These units can be wired for either
portability, with flexible 3-wire cord, or permanent installation using a supply with a ground.
To reduce the risk of electric shock, the motor must be securely and adequately grounded! This can be
accomplished by either: 1) Inserting plug (portable) directly into a properly installed and grounded 3-prong
grounding type receptacle (as shown) in Figure A for 110-120 volt, or Figure B for 220-240 volt); 2)
Permanently wiring the unit with a grounded, metal raceway system; 3) Using a separate ground wire
connected to the bare metal of the motor frame; 4) Other suitable means. The green (or green and yellow)
conductor in the cord is the grounding wire. Figure 2 Grounding Methods
Figure 2 - Grounding Methods
WARNING: NEVER CONNECT THE GREEN (OR GREEN AND YELLOW) WIRE TO A LIVE TERMINAL
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. Use only 3-wire extension cords
that have 3-prong, grounding type plugs, and 3-pole receptacles that accept the equipment plug.
16. Use only 3-wire extension cords that have 3-prong, grounding type plugs and 3-pole receptacles that
accept the equipment plug.
