3.1.3.3
installation recommendations
1.
If the pump is located below water level,
isolation valves must be installed on both sides
of the pump to prevent back flow of pool water
during any routine or required servicing.
2.
To help prevent difficulty in priming, install the
suction pipe without high points (above inlet of
pump - inverted “U”s in plumbing), which can
trap air. For installations of equipment up to 100
feet from the water, refer to the pipe sizing chart,
Table 1. For installations of equipment more than
100 feet from the water, the recommended pipe
must be increased to the next size.

3.
SHP Pumps come 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 SHP Pump must be connected to at least two
(2) hydraulically balanced main drains (suction
outlets) for each pool pump suction line. Each
drain must be provided with covers that are listed
or certified to the latest version of ANSI/ASME
A112.19.8. The suction outlets of the main drains
must be at least three (3) feet apart or at different
planes. The suction outlets 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 requirements.
notE
To prevent entrapment, the system must be built so
that 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. However, if two (2) main drains run into
a single suction line, the single suction line may be
equipped with a valve which will shut off both main
drains from the pump.
5.
The piping must be well supported and not
forced together where constant stress will be
experienced.
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. Every additional
fitting has the effect of moving the equipment
farther away from the water.
notE
If more than 10 suction fittings are needed, the pipe
size must be increased.
8.
If this is a new installation, pressure test
according to local codes. See
Section 3.3,
Pressure Testing.
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 could cause overheating, reduce the motor
life, and result in higher electric bills.
It is the responsibility of the electrical installer to provide
data plate operating voltage to the pump by ensuring
proper circuit sizes and wire sizes for this specific
application.
The National Electrical Code (NEC, NFPA-70) 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.
Caution
Failure to provide data plate voltage (within 10%)
during operation will cause the motor to overheat and
void the warranty.
3.2.2 Bonding and grounding
1.
The motor frame must be grounded to a reliable
grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or
larger must be used. If the pump is installed within
five (5) feet of the inside walls of the swimming
pool, spa, or hot tub, the motor frame must be
bonded to all metal parts of the swimming pool,
spa, or hot tub structure and to all electrical
equipment, metal conduit, and metal piping within
five (5) feet of the inside walls of the swimming
pool, spa, or hot tub.
2.
Bond the motor using the provided external lug.
