Installation & Operation Manual
NOTE: To prevent entrapment, the system must be
built so it cannot operate with the pump drawing
water from only one main drain. At least two main
drains must be connected to the pump when it is in
operation. However, if two 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.
4. The piping must be well supported and not forced
together where it will experience constant stress.
5. Always use properly sized valves. Jandy Diverter
Valves and Ball Valves typically have the best ow
capabilities.
6. Use the fewest possible ttings and limit the use of
90 degree elbows. Each additional tting or length
of pipe increases resistance to ow which makes
the pump work harder.
NOTE: If more than ten suction fittings are needed,
the pipe size must be increased.
7. Every new installation must be pressure tested
according to local codes.
3.2.4 Adjustable Bases VSFHP Models
To replace an existing pump with dierent dimensions,
use the adjustable bases to correctly align the suction
and discharge ports with existing plumbing. The VS
FloPro base and spacers increase the total height of
the pump and the height of the suction side port of the
pump. See Figure 5 and Table 2.

2. The unions on both the suction and discharge ports
simplify installation and service while eliminating
the possibility of leaks at threaded adapters.
3. The pump must be connected to at least two
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 certied 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 feet (1 m) apart
or at dierent planes. The suction ttings can be a
drain and skimmer, two drains, two skimmers, or a
skimmer with an equalizer line installed. Check the
local codes for proper installation.
