backwards. NEVER attempt to start pump if shaft is rotating due to a
hydraulic turbine action, this COULD cause pump to operate in reverse
and damage internal components.
DRAINS, SUCTION FITTINGS AND JETS
1. Do not allow anyone, child or adult, to play with or sit on any suction
outlet (drain) or wall vacuum fittings!
2. Pull long hair back into a ponytail or a bathing cap.
3. Remove jewelry before entering the swimming pool.
4. Have a licensed professional inspect all suction outlets.
5. Ensure that drain covers are ANSI/APSP-16 (2011) certified and wall
vacuum fittings are self closing/self latching.
6. Replace any broken drain covers, missing covers or uncertified covers
with ANSI/APSP-16 (2011) certified covers.
ELECTRICAL HAZARDS
A licensed electrician, experienced in swimming pools and spas, SHOULD
inspect your equipment to make sure everything is properly grounded,
bonded and protected by proper GFCI circuits according to Article 680 of
the National Electric Code.
INDOOR INSTALLATIONS
Swimming pools and spas located indoors must comply with ANSI/
ASHRAE Standard 62-2001 to ensure adequate ventilation and safe use.
Do NOT enter the swimming pool if the drain
cover is broken or missing. CLOSE the
swimming pool or spa. Immediately call your swimming pool
professional to make repairs.

ENTRAPMENT PROTECTION
Refer to ANSI/APSP-7-2006 or latest version for avoiding suction
entrapment. The pump suction must be designed to eliminate the possibility
of suction entrapment or hair entrapment/entanglement.
SUCTION COVERS
Do NOT enter the swimming pool if drain cover is broken or missing. Call
your swimming pool professional immediately to make repairs.
TESTING AND CERTIFICATION
All suction inlet covers must comply with ANSI/APSP-16 (2011)
specifications for suction fittings for use in swimming pools, spas
and whirlpool bathtub applications. The product must be tested for
compliance with the standards and the certification must be included with
the components.
OUTLETS PER PUMP
Provide at least two hydraulically balanced main drains, with covers for
each swimming pool pump suction line. The centers of the main drain's

suction fitting must be at least 3 feet apart (Figure A). The system must
be built so that it cannot operate with the swimming pool pump drawing
water from only one main drain. Two main drains must be connected to the
swimming pool pump whenever it is running. A valve in each suction line
is not allowed.
1. Keep the piping as straight and short as possible, and of suitable size.
2. Do not connect an elbow directly into the pump inlet. A length of
straight pipe will allow proper entry of the water to the pump.
3. Slope horizontal runs upward to the pump to prevent trapping air.
4. Use independent piping supports to alleviate strain on the pump.
5. Keep as much of the suction line as possible below the water level to
reduce priming time.
6. Install valves and unions in the pump suction and return lines to
facilitate servicing. Do not use valves to throttle the pump. Valves are
essential for pump maintenance if the system is installed below deck
level.
INSTALLATION
NOTE: Refer to ANSI/APSP/ICC-15-2011 or latest version for guidelines on
proper pump selection.
LOCATION
Locate pump as close to swimming pool/spa as possible on a non-
combustible surface. Install the pump on a hard, level surface that is dry,
well ventilated and away from direct sunlight. The surrounding area should
provide protection from the elements and ample room for maintenance
and service. Ensure the drainage will flow away from the pump.
Mount pump below water level for easy priming. If the pump must be
located above the filled water level, keep the vertical distance to a minimum.
Excessive pipe strain caused by incorrect
alignment may cause pump housing failure.
PUMP PLUMBING
Explosion/fire hazard:
adhesive in a well ventilated area.
SOLVENT WELD CONNECTIONS
Use rigid or flexible PVC pipe. Ensure pipe ends are clean and
free of any flash caused by the cutting operation. Use the proper
adhesive for the type of pipe specified.
NOTE: Use an adhesive primer to ensure adhesive joints are
secure. Primers are available with a purple tracer to qualify in areas
where codes specify a primer must be used.
Consider climatic conditions when applying adhesives.
Atmospheric conditions with high humidity will make the adhesive
action of certain glues less effective. Follow the manufacturer's
instructions.
THREADED CONNECTIONS
Use only plumber's seal tape or equivalent on threaded plumbing
connections. Other pipe compounds may damage threads. Do not
use silicone or petroleum based compounds. Do not overtighten.
Hand tightening plus 1/2 turn is sufficient.
