Suction Outlets per Pump
Provide at least two hydraulically balanced main drains, with covers, as suction outlets for each circulating pump
suction line. The centers of the main drains (suction outlets) on any one suction line must be at least 3 ft. apart.
The system must be built so that it cannot operate with the pump drawing water from only one main drain. There
must be at least two main drains connected to the pump whenever it is running.
However, if two main drains run into a single suction line, the single suction line may be equipped with a valve
which will shut off both main drains from the pump.
More than one pump can be connected to a single suction line as long as the requirements listed above are met.
Water Velocity
The maximum water velocity through the suction fitting or cover for any suction outlet must be 1.5 ft. per second
unless the outlet complies with the latest ASME/ANSI Specification for Suction Fittings For Use in Swimming Pools,
Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum
designed flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum water velocity in the pump suction
hydraulic system must be 6 ft. per second or less even if one main drain (suction outlet) is completely blocked. The
flow through the remaining main drain(s) must comply with the latest ASME/ANSI Specification for Suction Fittings For
Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Testing and Certification
Suction outlet covers must have been tested by recognized testing laboratory and found to comply with the latest
ASME/ANSI Specifications for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications.
Fittings
Fittings restrict flow; for best efficiency use the fewest possible fittings (but at least two suction outlets). Avoid fittings
which could cause an air trap. Pool fittings must conform to International Association of Plumbing and Mechanical
Officials (IAPMO) standards. Use only non-entrapping suction fitting or double suction.
Electrical
WARNING:
Risk of electric shock. Can shock, burn or kill. Ground pump before connecting to power supply.
Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal
electrical shock hazard.
To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical problem. If GFCI trips and will not re-set,
have a qualified electrician inspect and repair electrical system.
Exactly match supply voltage to name plate voltage. Incorrect voltage can cause fire or seriously damage motor
and voids warranty. If in doubt consult a licensed electrician.
