ENTRAPMENT PROTECTION
The pump suction system must provide
protection against the hazard of
suction entrapment or hair
entrapment/entanglement.
SUCTION OUTLET COVERS
All suction outlet covers must be
maintained. They must be replaced if
cracked, broken, or missing.
See below for outlet cover certification
requirements.
All suction outlets must have correctly
installed, screw-fastened covers in place.
OUTLETS PER PUMP
(FIGURE 1)
Provide at least two hydraulically
balanced main drains, with covers, for
each swimming pool pump suction
pipe. The centers of the main drains
(suction fittings) must be at least three
feet apart.
The system must be built so that it
cannot operate with the pump
drawing water from only one main
drain (that is, 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 pipe, the single suction
pipe may be equipped with a valve
which will shutoff both main drains
from the pump.
More than one pump can be
connected to a single suction pipe as
long as the requirements above are
met.
WATER VELOCITY
The maximum water velocity through
any suction outlet must be 1.5 feet 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 fittings
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
feet per second or less even if one
main drain (suction fitting) is com-
pletely blocked. The flow through the
remaining main drain(s) must comply
with the latest ASME/ANSI Specifi-
cation 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 a nationally 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 fewest possible fittings.
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
Ground motor
before connecting
to electrical power supply. Failure to
ground motor can cause severe or fatal
electrical shock hazard.
Do not ground to a gas supply line.
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 reset, have a qualified electrician
inspect and repair electrical system.
Exactly match supply voltage to
nameplate voltage. Incorrect
voltage can cause fire or seriously
damage motor and voids warranty. If in
doubt, consult a licensed electrician.
