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.

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. 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 Pro
Series Diverter Valves and 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.
