The system must be built to include at least two (2) suction outlets (drains) connected to the pump
whenever the pump is running. However, if two (2) main drains run into a single suction line, the single
suction line may be equipped with a valve that will shut off both main drains from the pump. The system
shall be constructed such that it shall not allow for separate or independent shutoff or isolation of each
drain.
More than one (1) pump can be connected to a single suction line as long as the requirements above are
met.
Water Velocity: The maximum water velocity through the suction fitting or cover for any suction outlet
must be 1.5 feet per second, unless the outlet complies with the latest published edition of ANSI/ASME
A112.19.8 (ANSI/APSP-16, 2011), the standard for Suction Fittings For Use in Swimming and Wading
Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction if
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 six (6) feet per second or less, even if one (1) main drain (suction
outlet) is completely blocked. The flow through the remaining main drain(s) must comply with the latest
published edition of ANSI/ASME A112.19.8 (ANSI/APSP-16, 2011), the standard for Suction Fittings For
Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Testing and Certification: Suction outlet covers must have been tested by a nationally recognized
testing laboratory and found to comply with the latest published edition of ANSI/ASME A112.19.8 (ANSI/
APSP-16, 2011), the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot
Tubs, and Whirlpool Bathtub Applications.
Fittings: Fittings restrict flow; for best efficiency use fewest possible fittings (but at least two (2) suction
outlets).
Avoid fittings that could cause an air trap.
Pool cleaner suction fittings must conform to applicable International Association of Plumbing and
Mechanical Officials (IAPMO) standards.
WARNING - Risk of Electrical Shock or Electrocution
This pool pump must be installed by a licensed or certified electrician or
a qualified pool serviceman in accordance with the National Electrical
Code and all applicable local codes and ordinances. Improper installation
will create an electric hazard which could result in death or serious injury
to pool users, installers, or others due to electrical shock, and may also
cause damage to property.
Always disconnect power to the pool pump at the circuit breaker
before servicing the pump. Failure to do so could result in death or
serious injury to serviceman, pool users, or others due to electric shock.
