Installation (Cont.)

The pump mount must be located away from corrosive or flammable chemicals. Do not connect the pump to a municipal water system. The pump is only designed for pool or spa installation. The pump must be installed with at a minimum of 2 main drains equipped with certified anti-entrapment cov- ers that comply with ASME/ANSI A119.19.8 standard (see Figure 2). All air must be re- moved from piping system before operating or testing equipment (see filter manual).

THREADED CONNECTIONS

Use only Teflon® tape or equivalent on threaded plumbing connections. Other pipe compounds may damage threads. Do not use silicone or petroleum based compounds.

PUMP PLUMBING

Suction pipe should be as large as or larger than discharge pipe. Avoid us- ing a suction pipe smaller than pump connection. The pump is designed to accept either 2 or 3 inch suction piping. Larger diameter pipes reduce noise and improve performance.

1.Keep the piping as straight and short as possible, and of suitable size.

2.Avoid connecting 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 reduce 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. Valves are also essential for pump maintenance if the system is installed below pool water level.

7.Keep all valves fully open during operation. Partially closed valves waste energy!

Use Teflon tape for making threaded

connections to the pump. Do not use pipe dope.

TEFLON TAPING INSTRUCTIONS

Use only new or clean PVC pipe fittings. Wrap male pipe threads with one to two layers of Teflon tape. Cover entire threaded portion. Do not over tighten. If leaks occur, remove pipe, clean off old tape, rewrap with one to two additional layers of tape and remake the connection.

Internal - 2 in. NPT are available for direct

connection to pipe. The suction line is also designed to accept 3 in. NPT external threaded connection. For best results use the larger diameter suction line.

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 Associa- tion of Plumbing and Mechanical Officials (IAPMO) standards. Use only non-entrap- ping suction fitting or double suction.

PRIOR TO PRESSURE TESTING

•Securely tighten knobs, drain fittings, lid, and system accessories

•Air may collect at the highest point in the plumbing system. Normally an air purge valve is provided with the pool filter. Consult pool filter instruction manual for air purging instructions.

•Basket lid must be rotated and locked into position as indicated in Figure 3.

Figure 3 - Clamp rings

•Test system at a water pressure of 25 psi or less

•Water Temperature for test must be less than 100° F

•After 24 hours visually check system for leaks.

POOL PUMP SUCTION REQUIREMENTS

Pump suction is hazardous and can trap,

drown or disembowel bathers. Do not use or operate swimming pools or spas if a suction outlet cover is missing, broken, or loose.

Follow the guidelines below for a pump installation which minimizes risk to users of pools and spas.

Ground the motor before connecting

to electrical power supply. Failure to ground the motor may cause severe or fatal electrical shock hazard.

ENTRAPMENT PROTECTION

The pump suction must be designed to eliminate the possibility of suction entrap- ment or hair entrapment/entanglement.

SUCTION COVERS

All suction inlet covers must be maintained and replaced if cracked, broken, or missing. See Figure 2 for outlet cover certification requirements.

TESTING AND CERTIFICATION

All suction inlet covers must comply with ASME/ANSI A112.19.8 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.

Single or Multiple Pump Circulation Sys- tems must be provided with a minimum of 2 (two) suction inlets of the approved type.

Do not install multiple pumps in one hydraulic circuit. The pump is not designed to accept output flow from another pump. Do not allow water to back flow through the pump. Water flowing in the discharge and out the suction during an upset condition can cause the motor to rotate 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.

Any pool or spa should immediately

be closed if the cover or grate is damaged or missing.

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 drains suction fitting must be at least three feet apart (see Figure 2). The system must be built so that it cannot operate with the pump drawing water from only one main drain. Two main drains must be con- nected to the pump whenever it is running. If two main drains run into a single suction line, the single suction line can be equipped with a single valve that shuts off both main drains from the pump. A valve in each suction line is not allowed.
