3. The pump and other circulation equipment must
be located more than five (5) feet from the water.
Choose a location that will minimize turns in the
piping.
NOTE In Canada, the pump must be located a
minimum of three (3) meters (approximately 10
feet) from the water (CSA C22.1).
4. The pump must be placed on a solid foundation
that will not vibrate. To further reduce the
possibility of vibration noise, bolt the pump to the
foundation, or place it on a rubber mat.
NOTE Zodiac Pool Systems, Inc. recommends bolting
the pump directly to the foundation.
5. The pump foundation must have adequate drainage
to prevent the motor from getting wet. Protect the
pump from the rain and sun.
6. Proper ventilation is required for the pump to
operate normally. All motors generate heat that
must be removed by providing proper ventilation.
7. Provide access for future services by leaving a
clear area around the pump. Allow plenty of space
above the pump to remove the lid and basket for
cleaning.
8. If the equipment is in a potentially dark area,
provide adequate lighting.

3.1.3 Pipe Sizing

3.1.3.1

Suction Pipe

When the pump is located up to 50 feet (15 m) from
the pool, the recommended minimum pipe size for the
suction side of the pump is two (2) inches (5 cm). For
suction lengths greater than 50 feet see Section 3.1.3.3
Step 2.
3.1.3.2

Discharge Pipe

When the pump is located up to 50 feet (15 m) from
the pool, the recommended minimum pipe size for the
discharge side of the pump is two (2) inches (5 cm).
For discharge lengths greater than 50 feet (15 m) see
Section 3.1.3.3 Step 2.
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 the 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, commonly referred to in
plumbing as an airlock) that can trap air.

Installation and Operation Manual
For installations of equipment up to 100 feet (30
m) from the water, refer to Table 1, the pipe sizing
chart. For installations of equipment more than
100 feet (30 m) from the water, the recommended
pipe size must be increased to the next size.

3. VS-FHP 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 VS-FHP Pump must be connected to at least
two (2) hydraulically-balanced main drains for
each pool pump suction line. Each drain must be
provided with covers that are listed or certified
to the latest published edition of ANSI/ASME
A112.19.8. 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. However, 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 Diverter
Valves and Jandy Ball Valves typically have the
best flow capabilities.
7. Use the fewest fittings possible. Each additional
fitting has the effect of moving the equipment
farther away from the water.
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.
