This booster pump is 3/4 horsepower with a 1.5

service factor producing a minimum of 50 psi at 12 GPM.

1. UNIT LOCATION

Pump should be installed on a firm and level surface.
Unless required by a local code, it need not be bolted
down. Installation should be as close as possib

le to a
filtered water return line and convenient location for
servicing. NOTE: Booster pump must always be con-

nected to return line on discharge side of filter. Nev

er
connect suction side booster pump ahead of filter. (See
Figure 1).

2. TYPICAL INSTALLATION - HEATER
CONSIDERATION

Suction side of booster pump must be connected to

the return line after the heater.

Except on solar installa­tion, never connect suction side of booster pump ahead
of filter or heater. NOTE: Keep booster pump a mini-

mum of 3 feet from heater.

k-up, when in­stalling any one of Pentair automatic pool cleaners in a
pool with solar heating, the in-line tee must be installed
on the return line between the filter and the solar
heater. This minimizes the possibilities of an air lock in
the sweep pump each time the solar panel is filled and
assures an ample supply of water. (See Figure 2B).

Use elbow and reducing bushing if needed on pre-

plumbed installation. Use tee on existing installation.

Connect pump suction to the return line after filter and
heater as follows: Preferably, underneath side
(NEVER ON TOP) of the horizontal return line.

6. INSTALLATION OF PUMP HOSES

a. To install hoses remove adapter from hose kit bag
(P/N 353020) and wrap thread seal tape around the 3/4
inch npt threads of the adapter. A minim

um of four

revolutions is required.

b. Screw adapter with thread seal tape into the pump
outlet. Torque to 60 inch x lbs

.

c. Cut hose to appropriate length. Six (6) feet of
hose has been pro

vided for both the inlet and outlet.

d. Place adapter cap over hose (See Figure 4) and
slide the hose onto the adapter until the hose is flush
against the wall where the threads begin. Heating of
the hose or use of a lubricant may be useful if the hose
is cold.

e. Screw adapter cap and tighten to the adapter to
secure the hose. Torque to 60 in. x lbs.

f. Repeat process for both inlet and outlet of pump.
When routing the hose make sure there are no tight
bends or kinks in the hose.

8. ELECTRICAL CONNECTIONS FOR BOOSTER
PUMP

Pentair Universal Booster Pump is pre-wired to

ate on 230 volts. The motor can also be wired to

oper

ate on 115 volts by making a simple modification

oper
at motor wire connection plate.

BEFORE TURNING ON POWER TO PUMP,

CHECK VOLT

AGE AT INTENDED SOURCE BEFORE
MAKING ELECTRICAL CONNECTION. PUMP
MOTOR CAN BE DAMAGED IF CONNECTED TO
WRONG VOLTAGE.

ELECTRICAL WORK SHOULD BE DONE BY A

LICENSED ELECTRICIAN.

CHECK ELECTRICAL CODES FOR REQUIRE-

MENTS IN YOUR LOCAL AREA.

9. SAFETY WARNING

Motor frame should be grounded for swimming pool
installations as specified in Article 680 of the National
Electrical Code. Failure to proper

ly ground motor can

result in serious electrical shock.

10.TIME CLOCK

A separate time clock is recommended. To ensure
proper sequence of filter pump and booster pump, the
time clocks must be reset if po

wer is interrupted.

The automatic pool cleaner must be run for a
length of time necessary to clean the pool, but should
never be allowed to run while filter system is off. This
will result in damaging the booster pump. Running the
automatic pool cleaner without the filter system in oper­ation will void warranty. The automatic pool cleaner
should start operating one half hour to forty-five min­utes after the filter pump starts and stop one half hour
to forty-five minutes before the filter pump
stops.

11.MANUAL SWITCH

A manual switch is recommended. It should be

located between the time clock and the booster pump.

witch eliminates turning the pump off at the time

This s
clock.

12.PUMP SEAL

The booster pump is fitted with a mechanical shaft

seal which is water lubricated and water

cooled. If the

pump is run without water this seal will be damaged.

NEVER OPERATE UNLESS FILTER SYSTEM IS ON.

13.SERVICING THE BOOSTER PUMP

Note: This motor is a drip proof motor, but can be

damaged by rainfall, splash or flooding by causing

ater to enter the motor.

- To disassemble the booster pump -

1. Turn off booster pump motor and close v

alves.

2. Unscrew suction line in middle of volute.

3. Loosen nuts and remove bolts between booster
pump volute and seal bracket.

4. On back end of motor remove cap. Use a crescent
wrench or open end wrench to hold shaft from
spinning.

5. Hold wrench and turn impellar counter clockwise
to remove.

- To remove seal -

1. Stand motor on end, using one screwdriver slowly

y seal out of impellar. Remove seal bracket and

pr
dislodge seal from backside of seal bracket using
hammer and screwdriver.

- To re-assemble the unit -

1. After replacing the necessary parts, re-assemble
by reversing order of steps 1-5 abo

ve.

2. Ceramic seat must be perfectly clean of any
foreign objects or dirt. If seat is not clean, it will
cause leakage. The ceramic seat must go in with
the side containing grooves facing into the center
of the rubber gasket, otherwise it will leak.

3. Replace impellar and seals if warped or discolored.
This condition is caused by overheating due to
pump running dry. Smooth surface of ceramic seal
should be parallel to and facing away from back
side of impellar.

4. Silicone backside of metal flange on spring seal,
push down until flush in center of seal bracket.
Be careful not to get silicone on to spring seals
contact surface.
