3. The pump comes equipped with unions on both
the suction and discharge ports. This feature
simplifies installation and service and eliminates
the possibility of leaks at threaded adapters.
4. The pump must be connected to at least two (2)
hydraulically-balanced main drains for each pool
pump suction line. Each drain (suction outlet)
assembly must be equipped with covers and must
be listed or certified to the latest published edition
of ANSI
/ASME
A112.19.8, or its successor

standard, ANSI/APSP-16. The suction fittings of
the main drains must be at least three (3) feet (1
m) apart or at different planes. The suction fittings
can be a drain and skimmer, two (2) drains, two
(2) skimmers, or a skimmer with an equalizer
line installed. Check the local codes for proper
installation.
NOTE To prevent entrapment, the system must be
built so it cannot operate with the pump drawing
water from only one (1) main drain. At least two
(2) main drains must be connected to the pump
when it is in operation. If two (2) main drains run
into a single suction line, the single suction line
may be equipped with a valve that will shut off
both main drains from the pump.

5. The piping must be well supported and not forced
together where it will experience constant stress.
6. Always use properly sized valves. Jandy Pro
Series Diverter Valves and Ball Valves typically
have the best flow capabilities.
7. Use the fewest fittings possible.
NOTE If more than ten (10) suction fittings are needed,
the pipe size must be increased.
8. Every new installation must be pressure tested
according to local codes.
3.2
Electrical Installation
3.2.1 Voltage Checks
The correct voltage, as specified on the pump data plate,
is necessary for proper performance and long motor life.
Incorrect voltage will decrease the pump's ability to
perform and can cause overheating, reduce motor life,
and result in higher electric utility cost.
It is the responsibility of the electrical installer to
provide the correct operating voltage to the pump by
ensuring proper circuit sizes and wire sizes for the
specific application.
The National Electrical Code
requires all pool pump circuits be protected with a
Ground Fault Interrupter (GFCI). Therefore, it is also
the responsibility of the electrical installer to ensure that
the pump circuit is in compliance with this and all other
applicable requirements of the National Electrical Code
(NEC) and any other applicable installation codes.
