FITTINGS
Fittings restrict flow; for best efficiency use the fewest number of 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.
POOL PUMP SUCTION REQUIREMENTS
Pump suction is hazardous and can trap, 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. Follow the
guidelines below for a pump installation which minimizes risk to all users of
pools, spas, and hot tubs.
ENTRAPMENT PROTECTION
The pump suction must be designed to eliminate the possibility 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 Testing and Certification for outlet cover certification requirements.
All suction outlets must have correctly installed, screw fastened covers in place.
TESTING AND CERTIFICATION
All suction inlet covers must comply with ASME/ANSI specifications for suction fittings for use in swimming pools, spas, hot tubs, and whirlpool
bathtub applications. The product must be tested for compliance with the standards, and the certification must be included with the components.
Suction inlets must be designed so that water is drawn simultaneously. A vacuum relief device can be installed in line leading to the pump
suction.
All suction outlet covers must conform to ASME/ANSI A112.19.18M; or must be a minimum 18 x 23 grate or larger; or must have an approved
channel drain system. Skimmers are exempted. All pool and spa single or multiple outlet circulation systems shall be equipped with an
atmospheric vacuum relief system. The system must be ASME/ANSI A112.19.17 rated.
Any pool or spa shall immediately be closed if the cover or grate is damaged or missing.
Suction outlet covers/grates shall be tested and listed by a nationally recognized testing laboratory as conforming to ASME/ANSI A112.19.8.
ELECTRICAL
Ground the motor before connecting to electrical power supply. Failure to ground the motor may cause severe or fatal electrical shock hazard.
Never 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.
Verify that supply voltage matches the nameplate voltage. Incorrect voltage can cause fire or seriously damage motor and voids warranty.
VOLTAGE
Voltage at motor must be within 10% of the motor nameplate rated voltage or motor may overheat, causing overload tripping and reduced
component life. If voltage does not fall within the specified range during operation consult the power company.
GROUNDING/BONDING
Install, ground, bond and wire motor according to local or National Electrical Code requirements. Permanently ground the motor. Use the ground
terminal provided in the terminal box on the back of the motor. Use size and type wire required by local codes. Connect motor ground terminal to
electrical service ground.
Bond motor to pool structure. Use a solid copper conductor, size No.8 AWG or larger. Run wire from external bonding lug to reinforcing rod or
mesh.
