Testing and Certification
Suction outlet covers must have been tested by a nation-
ally recognized testing laboratory and found to comply
with the latest ASME/ANSI Specification for
Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications.
Outlets Per Pump
Provide at least two hydraulically balanced main drains,
with covers (see Page 5), for each swimming pool pump
suction line. The centers of the main drains (suction fit-
tings) 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). (See Figure 2).
However, if two main drains run into a single suction
line, the single suction line may be equipped with a valve
which will shutoff
both main drains from the pump (see
Figure 2).
More than one pump can be connected to a single suc-
tion line 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/SNSI Specification for
Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications. In any case, do not ex-
ceed 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 completely blocked.
The flow through the remaining main drain(s) must com-
ply with the latest ASME/ANSI Specification for
Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications.
ELECTRICAL
Ground motor before
connecting to electrical
power supply. Failure to
ground motor can cause se-
vere 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 be-
fore working on electrical
connections.
Ground Fault Circuit
Interrupter (GFCI) trip-
ping 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 dam-
age motor and voids warranty. If in doubt consult a li-
censed electrician.
Voltage
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may over-
heat, causing overload tripping and reduced component
life. If voltage is less than 90% or more than 110% of
rated voltage when motor is running at full load, consult
power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local
or National Electrical Code requirements.
Permanently ground motor. Use green ground terminal
provided under motor canopy or access plate (See Figure
3); use size and type wire required by code. Connect
motor ground terminal to electrical service ground.
Hazardous voltage.
Can shock, burn,
or cause death.
Ground pump before
connecting to
power supply.
