NOTE

All pipe sizes are able to withstand the pressures

the pump will deliver, but not necessarily the flow. If

the pipe is too small for the pump, or it is elevated

above water, the maximum gallons per minute (GPM)

may not be delivered. If this happens, the pump will

develop an air pocket (cavitation) that will make noise

and the pump life will be shortened.

3.1.3.3

Installation Recommendations

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.

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.

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.

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 (suction outlet) assembly must be provided

with covers and must be listed or certified to the

latest version of ANSI

successor standard, ANSI/APSP-16. 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.

The piping must be well supported and not

forced together where constant stress will be

experienced.

Always use properly sized valves. Jandy Pro

Series Diverter Valves and Ball Valves typically

have the best flow capabilities.

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.

If this is a new installation, pressure test

according to local codes. See Section 3.3,

Pressure Testing.

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

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

In addition to being properly grounded as

described below in Sec. 3.2.3, and in accordance

with the requirements of the National Electrical

Code (NEC), or in Canada the Canadian

Electrical Code (CEC), the pump motor must

be bonded to all metal parts of the swimming

(NEC

, NFPA-70

)
