4.2 Pump Installation
WARNING
AstralPool pumps are powered by a high voltage electric motor and
must be installed by a licensed or certified electrician or a qualified
swimming pool service technician.
When installing the appliance, ensure all parts are installed in the
correct zone in accordance with the wiring rules. In particular refer
to AS/NZS 3000 (Australia) and EN 60364 (EU).
1. The pump must be connected to at least two
hydraulically-balanced main drains for each pool pump
suction line.
2. Each drain (suction outlet) assembly must be provided
with covers and must be listed or certified to the latest
published edition of ANSI
®
/ASME
®
A112.19.8, its
successor standard, ANSI/APSP-16 or the AU/NZS
1926.3-2010.
3. The suction fittings of the main drains must be at least
1m apart, center to center, or on different planes. The
suction fittings can be a drain and skimmer, two drains,
two skimmers, or a skimmer with an equalizer line
installed. Check 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 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. An external by-pass valve must be installed before
the filter if the flow rate exceeds 500 lpm (132 gpm).
Refer to the manufacturer’s recommendations if using a
different brand heater (see Figure 11 Inset).
WARNING
A check valve can interfere with the proper operation of certain
Suction Vacuum Release System (SVRS) products. To avoid
possible entrapment hazard, serious injury, or death, make sure
to review the operation/owners manual of your particular SVRS
product before installing the check valve.
5. Install a corrosion resistant check valve in the return line
if sanitation equipment such as erosion feeders and salt
chlorination systems are installed (see Figure 11).
