3.2.1 Electrical Wiring
1.
The pump motor must be securely and adequately
grounded using the green screw provided. Ground
before attempting to connect to an electrical power
supply. Do not ground to a gas supply line.
2.
Wire size must be adequate to minimize voltage
drop during the start-up and operation of the
pump. See Table 1 for wire sizes.
3.
Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. To prevent wire
nuts from loosening, tape them using a suitable,
listed (UL, ETL, CSA) electrical insulating tape.
For safety, and to prevent entry of contaminants,
reinstall all conduit and terminal box covers. Do
not force connections into the conduit box.
4.
To configure the internal wiring of the pump motor
for the correct voltage, refer to the diagram on the
motor data plate.
5.
The starting current of the booster pump motor
may exceed 15 amps on 115 VAC voltage line. It
is recommended that a 20 amp service breaker be
used for the pump connected to 115 VAC.
6.
The booster pump motor is factory wired for 230
volts, but can be wired for either 115 or 230 volts.
To rewire to 115 volt, follow the instructions on
the name plate located on the back of the motor or
the sizing plate on the side of the motor.

7.
A separate time clock (in addition to the filtration
system time clock) is recommended to control the
On/Off functions of the booster pump. A manual
switch can also be used.
8.
If a time clock is used, set it to turn the pump
on at least a half an hour after the pool filtration
pump is turned on, and turn the pump off at least
half an hour before the filtration pump shuts off.
Periodically check the time clock settings to make
sure they are properly synchronized.

Plumbing
CAUTION
Be careful not to overtighten any pipe fitting on the
inlet or outlet of the booster pump. Overtightening
can cause the housing to crack.
3.3.1 Requirements
The Polaris Booster Pump requires a dedicated
return line. Plumb the booster pump into the system so
that it always receives flow from the filtration pump.
To ensure proper function of the pump and the cleaner,
refer to Figure 2 and adhere to the following guidelines
for specific equipment.
1.
Plumb the dedicated line upstream of all air
inducing equipment.
NOTE
Plumb the booster pump up-stream
of all air inducing equipment.
