Figure 2. Typical Piping Installation
NOTE
In Canada, the minimum distance maintained from
the edge of the pool and/or spa as noted above must be
3 meters (10 feet), as required by the Canadian Electrical
Code (CEC, 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
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 Table 1.
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. See Table 1.
Installation Recommendations
1. To help prevent difculty 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.

2. VS FloPro Pumps come equipped with unions on
both the suction and discharge ports. This feature
simplies installation and service and eliminates
the possibility of leaks at threaded adapters.
3. The VS FloPro 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 provided with covers and must be
listed or certied to the latest published edition of
ANSI
®
/ASME
®
A112.19.8, or its successor standard,
ANSI
®
/APSP-16. The suction ttings of the main
drains must be at least three (3) feet (1 m) apart or at
different planes. The suction ttings can be a drain
and skimmer, two (2) drains, two (2) skimmers, or a
