Pipe Sizing; Pump Location - Zodiac Pool Systems Polaris PB4-60 Manuel D'installation Et D'utilisation

2. If a heater is installed on the system, tap the
inlet for the booster pump into the return line
downstream and at least three (3) feet (1 meter)
from the heater discharge. See Figure 2. Do not
tap the booster pump inlet into the three-foot
(1 meter) section of heat sink pipe that comes
directly out of the heater.
3. Some solar heating systems utilize the entire water
flow when the panels are being purged of air. If the
pump is installed in a non-flow pipe during solar
panel purges, install an automatic override to shut
off the pump.
4. Plumb the booster pump inlet higher, upstream and
as far away as possible from a chlorinator.

3.3.2 Pipe Sizing

1. Use rigid PVC pipe with a minimum diameter
of 3/4", 1-1/2" is recommended, for the
dedicated return line. Flexible PVC piping is not
recommended for the dedicated pool return line
underground as it can be damaged by expansion
and movement caused by the surge of pump
pressure. Refer to Figures 3 and 4.

2. The booster pump inlet connection line should be
at least 3/4" pipe. The Softube quick connect is
designed to work with the Polaris reinforced
hose (part #P19) only.
3. Do not tap into the top of a horizontal line.
4. Use 90° street ells to minimize bends and loops in
the Polaris reinforced hose.

3.3.3 Pump Location

1. Zodiac Pool Systems, Inc. recommends installing
the pump within one 1 foot (30 cm) above the
water level. The pump should not be elevated
more than a few feet above 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.
Some Safety Vacuum Release System (SVRS)
devices 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. The pump and other circulation equipment must
be located more than 5 feet (1,5 meter) from the
water. Choose a location that will minimize turns
in the piping.
NOTE In Canada, the pump must be located a
minimum of 3.0 meters [approximately 10 feet]
from the water (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.
NOTE Zodiac recommends bolting the pump directly to
the foundation.
5. 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.
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 service by leaving a
clear area around the pump. Allow plenty of space
above the pump for servicing.
8. If the equipment is under cover, provide adequate
lighting.
