Pump must receive constant flow from the filter
pump. The PB4SQ is not a self priming pump.

• Install on a solid level surface that will not vibrate.
• A concrete slab/equipment pad is recommended.
• To reduce noise bolt the pump to the concret equipment pad.
• Ensure the equipment pad has sufficient drainage
• A dedicated return line is required.
• DO NOT USE flexible tubing of any kind for an underground return line.
• Plumb upstream of all air inducing equipment.

Location Requirements
WARNING
Some Safety Vacuum Release System (SVRS) devices
are not compatible with the installation of check valves.
If the pool is equipped with an SVRS device, be sure
to confirm that it will continue to safely operate when
check valves are installed.
NOTE: For installations in Canada the distance from the inner
pool edge must be 10' (3 m).
•
The pump along with all other circulation
equipment must be installed at least 5' (1.5 m) from
the inner pool edge. See Figure 3.
•
The pump must be placed on a solid foundation that
will not vibrate. See Figure 3.
•
Install the pump as close to the pool as possible and
in a position that will minimize bends in the piping.
•
Secure the pump by bolting it to the equipment pad.
This will also have the added benefit of helping to
reduce vibration noise. See Figure 3.
•
The booster pump inlet connection line should be at
least 3/4" pipe.

Electrical Connections
4.3.1
Supply Voltage
The pump can be wired for supply voltage of either
230VAC or 115VAC. The pump comes factory wired
for 230VAC installation. See section 4.3.3 for details
on wiring the motor for 115VAC supply. Correct
supply voltage is necessary for proper performance
and sustained motor life. It is the responsibility of the
electrical installer to provide proper operating voltage,
based on the pump motor rating information found here
or on the pump rating plate, ensuring proper circuit
sizes and wire sizes for this specific application.
The National Electrical Code
requires all pool pump circuits be protected with a
Ground Fault Circuit-Interrupter (GFCI). Therefore,
it is also the responsibility of the electrical installer

•
To help prevent difficulty in priming, install the
inlet line without high points or air locks.
•
The Quick Connect fittings are designed to work
with the Polaris reinforced hose. See Figure 8
•
Return line should be rigid PVC at 1 1/2" (40 mm)
Minimum. See Fig. 3
•
Plumb return line upstream of any air inducing
equipment.
•
Install the booster pump within 1' (30.5 cm) of the
pool surface. See Fig. 3
•
The pump should not be elevated more than a few
1' (30.5 cm) min.
Above Pool
Water Level
feet above the water level of the pool.
•
If the pump is installed below the water level,
check valves must be installed on both the inlet and
return lines to prevent back flow during service or
maintenance of the pump.
•
The equipment pad must have adequate drainage to
prevent water intrusion to the pump.
•
The pump needs to be protected from extreme
weather exposure.
•
Proper ventilation is required in order to avoid
excess heat buildup at the pump motor.
•
Ensure that sufficient service and maintenance
clearances are provided.
•
The area around the pump should be clear and free
of debris.
•
Sufficient space must be left above the pump to
allow access to the electrical connections.
•
If the equipment is under cover, provide adequate
lighting.
•
Do Not Install under the skirt or within the outer
enclosure of a spa.
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.
to ensure that the pump circuit is in compliance
with this and all other applicable requirements of
the National Electrical Code
applicable installation codes.
