Pump Location
WARNING
To Reduce the Risk of Fire, install pool equipment in an area
where leaves or other debris will not collect on or around
the equipment. Keep surrounding area clear of all debris
such as paper, leaves, pine-needles and other combustible
materials.
AstralPool recommends installing the pump within
30 cm (1 ft) above water level. The pump should not
be elevated more than 152 cm (5 ft). If the pump is
located below water level, isolation valves (check
valves) must be installed on both the suction and
return lines to prevent back flow of pool water during
any routine or required servicing.
WARNING
A check valve can interfere with the proper
operation of certain Suction Vacuum Release
System (SVRS) products. To avoid possible en-
trapment hazard, serious injury, or death, make
sure to review the operation/owners manual of
your particular SVRS product before installing the
check valve.
NOTE:
When the pool equipment is located below the
pool surface a leak can result in large scale water
loss or flooding. AstralPool cannot be responsible
for such water loss or flooding or damage caused
by either occurrence.
1.
Install the pump such that any disconnecting means
and/or junction boxes for power connection are within
sight of the pump and at least five feet horizontally
from the edge of the pool and/or spa. Choose a
location that will minimize turns in the piping.
2.
Place the pump on a solid foundation that will not
vibrate. To further reduce the possibility of vibration
noise, bolt the pump to the foundation.
3.
Ensure that the foundation has adequate drainage to
prevent the pump motor from getting wet.
4.
Make sure the pump has the proper ventilation to
prevent the motor from overheating. Overheating due
to lack of cooling voids warranty.
5.
Allow plenty of space for any maintenances by leaving
a clear area around the pump.
6.
Provide adequate lighting if the equipment is in a
potentially dark area.

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