SAFETY INFORMATION
Please read and understand this entire manual before attempting to assemble, operate or install the
product.
• NOTE: Pumps with the “UL” mark and pumps with the “US” mark are tested to UL Standard
UL778. CSA certied pumps are certied to CSA Standard C22.2 No. 108. (CUS.)
• ELECTRICAL SHOCK HAZARD.
Always disconnect power source before performing any work on or near the motor or its connected load.
If the power disconnect point is out-of-sight, lock it in the open position and tag it to prevent unexpected
application of power. Failure to do so could result in fatal electrical shock.
• ELECTRICAL SHOCK HAZARD.
Do not handle the pump with wet hands or when standing in water as fatal electrical shock could occur.
Disconnect main power before handling unit for ANY REASON!
• RISK OF ELECTRIC SHOCK.
These pumps have not been investigated for use in swimming pool areas.
DANGER
WARNING
• ELECTRICAL SHOCK ALERT.
To reduce the risk of electric shock, install only a circuit protected by a ground-fault circuit-interrupter (GFCI).
Make certain that the ground fault receptacle is within the reach of the pump’s power supply cord. DO NOT
USE AN EXTENSION CORD.
• ELECTRICAL SHOCK ALERT.
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSHA).
• ELECTRICAL SHOCK ALERT.
Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces, chemicals
or sharp objects. Replace damaged or worn wiring cord immediately.
• ELECTRICAL SHOCK ALERT.
As a safety measure, each electrical outlet should be checked for ground using an Underwriters Laboratory
Listed circuit analyzer which will indicate if the power, neutral and ground wires are correctly connected to your
outlet. If they are not, contact a licensed electrician.
• ELECTRICAL SHOCK ALERT.
These pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical
shock. DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE GROUND PIN.
• ELECTRICAL SHOCK ALERT.
Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers of proper capacity. A
separate branch circuit is recommended, sized according to the National Electrical Code for the current shown
on the pump nameplate.
• CHEMICAL ALERT.
