SUCTION HAZARD. Suction can cause serious injury
or death. Do not use this pump for wading pools,
shallow pools, or spas containing bottom drains,
unless pump is connected to at least two functioning
suction outlets.

WARNING: Pump suction is hazardous and can
trap and drown or disembowel bathers. Do not use or
operate swimming pools, spas, or hot tubs if a suction
outlet cover is missing, broken, or loose.
The following guidelines provide information for pump
installation that minimizes risk of injury to users of
pools, spas, and hot tubs:
Entrapment Protection
The pump suction system must provide protection against
the hazards of suction entrapment.
Suction Outlet Covers
All suction outlets must have screw-fastened covers
installed. All suction outlet (drain) covers must be
maintained. Drain covers must be listed/certified to the
latest published edition of ANSI/ASME A112.19.8 (ANSI/
APSP-16, 2011). They must be replaced if cracked,
broken, or missing.
Number of Suction Outlets Per Pump
Provide at least two hydraulically-balanced main drains,
with covers, as suction 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 (.9 m) apart,
center to center.
The system must be built to include at least two suction
outlets (drains) connected to the pump whenever the
pump is running. However, if two 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 so that it does not
allow for separate or independent shutoff or isolation of
each drain.
More than one 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 ft (.5 m) 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
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 (1.8 m) 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 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 the fewest
possible fittings (but at least two 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.
2. INSTALLATION
WARNING: Blockage of suction fittings can cause
A
serious or fatal injury due to drowning. To reduce the
risk of injury, do not permit children to use this product.
A
WARNING: Never work on the pump while it is
running or power is still connected. High voltage and
cause serious or fatal injury. A suitable ground fault
interrupter (GFCI) should always be installed at the
power supply source of this unit. Article 681-31 of the
NEC requires that a GFCI be used if this pump is used
with a storage pool. Be sure to ground the motor before
connecting to electrical AC power source. Failure to
ground the motor can cause serious or fatal electrical
shock hazard. DO NOT ground to a gas supply pipe line.
A
WARNING: The system's centrifugal pump operates
with electrical voltage, and can generate both vacuum
and pressure in the water system. When properly wired
and plumbed, this pump will operate in a safe manner.
