3.1 - GENERAL INFORMATION

Check carton for any evidence of damage due to rough
handling in shipment. If carton or any pump components
are damaged, notify the carrier immediately.
Failure to follow the safety instructions may result in
serious adverse health effects, or even serious or fatal
injury. Failure to follow the safety instructions will in all
cases invalidate all guarantees and liability on the part
of the manufacturer.
Avoid dry run of the pump, as long as the pump is not
filled with water.
This pump is equipped with a mechanical seal.
Damage to shaft seal could be the cause by non-obser-
vance of instructions.
Please follow instructions for filling up the pump accord-
ing to installation and instruction manual.
3.2 - APPLICATION
Only to be used to circulate swimming pool water.
3.3 - INSTALLATION
Only a qualified pump. Refer to "Important Pump Warn-
ing And Safety Instructions" for additional installation
and safety information.
LOCATION
Note: Do not install this pump within an outer enclosure
or beneath the skirt of a hot tub or spa unless marked
accordingly.
Note: Ensure that the pump is mechanically secured to
the equipment pad.
Be sure the pump location meets the following require-
ments:
1. Install the pump as close to the pool or spa as pos-
sible. To reduce friction loss and improve efficien-
cy, use short, direct suction and return piping.
2. Install a minimum of 1.5 meters (5 feet) from the
inside wall of the pool and spa.
3. Install the pump a minimum of 0.9 meters (3 feet)
from the heater outlet.
4. Do not install the pump more than 2.5 meters
above the water level.
5. Install the pump in a well ventilated location
protected from excess moisture (i.e. rain gutter
downspouts, sprinklers, etc.).
6. Install the pump with a rear clearance of at least
7.6 cm (3 inches) so that the motor can be removed
easily for maintenance and repair. See Figure 1.

PUMP INFORMATION
PIPING
1. For improved pool plumbing, it is recommended
to use a larger pipe size.
2. Piping on the suction side of the pump should be
the same or larger than the return line diameter.
3. Plumbing on the suction side of the pump should
be as short as possible.
4. For most installations Pentair recommends in-
stalling a valve on both the pump suction and re-
turn lines so that the pump can be isolated during
routine maintenance. However, we also recom-
mend that a valve, elbow or tee installed in the
suction line should be no closer to the front of the
pump than five (5) times the suction line diameter.
independently support the pipe near the
suction and discharge of the pump in or-
der to reduce the strain on the pump.
Avoid overtightening pipe connections. Use only
pipe sealants formulated for plastics. Do not use
petroleum based products. It is essential that the
suction line is free of air leaks. The suction line
should always be at least the same size as the
suction inlet of the pump. See Figure 2.
ELBOW
Example: A ø50 mm pipe requires a 250 mm straight
run in front of the suction inlet of the pump. This will
help the pump prime faster and last longer.
Note: DO NOT install 90° elbows directly into the pump
inlet or outlet.
