Pipe Sizing; Suction Pipe - Jandy Stealth SHPF.50 Manuel D'installation Et De Fonctionnement

Figure 2. Typical Piping Installation
NOTE
Better self-priming will be achieved if the pump is
installed as close as possible to the water level of the
pool.
2. If the pump is located below water level,
isolation 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
Some Safety Vacuum Release System (SVRS) de-
vices are not compatible with installation of check
valves. If the pool has an SVRS device, be sure to
confirm that it will continue to safely operate when
any check valves are installed.
3. 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 (5) feet horizontally from the edge of
the pool and/or spa. Choose a location that will
minimize turns in the piping.
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 should be installed on a firm, solid, and
level surface to avoid risk of settlement. Do not
use sand to level the pump as sand will wash away.
Check local building codes for any additional
requirements (Ex. Equipment pads in Florida must
be concrete and equipment must be secured to the
pad.)
NOTE
Zodiac Pool Systems LLC recommends bolting the
pump directly to the foundation.

ENGLISH
AQUAPURE
The pump foundation must have adequate drainage
to prevent the motor from getting wet. The pump
needs to be protected from the rain and sun.
Protect the pump from direct water exposure from
sprinklers, water runoff from rooftops and drainage,
etc. Failure to comply may cause pump failure, and
may void warranty.
Proper ventilation is required for the pump
to operate normally. All motors generate heat
that must be removed by providing proper
ventilation.
Provide access for future service by leaving a
clear area around the pump. Allow plenty of
space above the pump to remove the lid and
basket for cleaning.
If the equipment is under cover, provide
adequate lighting.
