RCD is defective. If the RCD interrupts power to the pump
without the test button being pushed, a ground current
is owing, indicating the possibility of an electric shock.
Do not use this pump! Disconnect the pump and have the
problem corrected by a qualied service representative
before using.
This pump is for use with permanent
swimming pools and may also be
used with hot tubs and spas if so marked. Do not use with
storable pools.
A permanently installed pool is constructed in/on the
ground or in a building such that it cannot be readily
disassembled for storage.
A storable pool is constructed so that it is capable of
being readily disassembled for storage and re-assembled
to its original integrity.

sure. There is a capacitor bank that holds a 230
VAC charge even when there is no power to the unit.
• The pump is not submersible.
• The pump is capable of high ow rates; use caution
when installing and programming to limit pumps
performance potential with old or questionable
equipment.
• Before servicing the pump; switch OFF power to
the pump by disconnecting the main circuit to the
pump.
• This appliance is not intended for use by persons
(incl. children) of reduced physical, sensory of men-
tal capabilities, or lack of experience and knowl-
edge, unless they have been given supervision or
instruction concerning the use of the appliance by
a person responsible for their safety.
FAILURE TO FOLLOW ALL INSTRUCTIONS AND WARNINGS CAN RESULT IN SERIOUS BODILY
INJURY OR DEATH. THIS PUMP SHOULD BE INSTALLED AND SERVICED ONLY BY A QUALIFIED
POOL SERVICE PROFESSIONAL. INSTALLERS, POOL OPERATORS AND OWNERS MUST READ THESE WARNINGS AND
ALL INSTRUCTIONS IN THE OWNER’S MANUAL MUST BE LEFT AT THE POOL OWNER.
SUCTION ENTRAPMENT HAZARD: Stay off the main drain and away from all suction outlets! This
pump produces high levels of suction and creates a strong vacuum at the main drain.
RISK OF ELECTRICAL SHOCK OR
ELECTROCUTION: PUMPS REQUIRE
HIGH VOLTAGE WHICH CAN SHOCK, BURN OR CAUSE
DEATH.
BEFORE WORKING ON THE PUMP,
ALWAYS DISCONNECT POWER TO THE
POOL PUMP AT THE CIRCUIT BREAKER
FROM THE PUMP. FAILURE TO DO SO
COULD RESULT IN DEATH OR SERIOUS
INJURY TO THE SERVICING PERSON,
POOL USERS OR OTHERS DUE TO ELECTRICAL SHOCK.
The use of unapproved covers or allowing use of the pool
or spa when covers are missing, cracked or broken can
result in body or limb entrapment, hair entanglement,
body entrapment, evisceration and/or death.
The suction at a drain or outlet can cause:
Limb Entrapment: When a limb is sucked or inserted into
an opening resulting in a mechanical bind or swelling. This
hazard is present when a drain cover is missing, broken,
loose, cracked or not properly secured.
Hair Entanglement: When the hair tangles or knots in
the drain cover, trapping the swimmer underwater. This
hazard is present when the ow rating of the cover is too
small for the pump or pumps.
Body Entrapment: When a portion of the body is held
against thedrain covertrapping theswimmer underwater.
This hazard is present when the drain cover is missing,
broken or the cover ow rating is not high enough for the
pump or pumps.
Evisceration / Disembowelment: When a person sits
on an open pool (particularly a child wading pool) or spa
outlet and suction is applied directly to the intestines,
causing severe intestinal damage. This hazard is present
when the drain cover is missing, loose, cracked or not
properly secured.
Mechanical Entrapment: When jewelry, swimsuits,
hairdecorations, ngers, toes or knuckles are caught
in an opening of an outlet or drain cover. This hazard is
present when the drain cover is missing, broken, loose,
cracked or not properly secured.

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS
NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN
ACCORDANCE WITH THE LATEST CODES, STANDARDS
AND GUIDELINES.
WARNING To minimize the risk of injury due to
suction entrapment hazard:
• Each suction cover must be installed at least 1m
apart, as measured from the nearest point to near-
est point.
• Regularly inspect all covers for cracks, damage and
advanced weathering.
• If a cover becomes loose, cracked, damaged, bro-
ken or is missing, replace with an appropriate cer-
tied cover.
• Replace drain covers as necessary. Drain covers
deteriorate over time due to exposure to sunlight
and weather.
• Avoid getting hair, limbs or body in close proximity
to any suction cover, pool drain or outlet.
• Disable suction outlets or recongure into return
inlets.
WARNING Aclearlylabeledemergencyshut-off
switch for the pump must be in an
easily accessible, obvious place. Make sure users know
where it is and how to useit in case of emergency.
WARNING Pumps improperly sized, installed or
used in applications other than for
which the pump was intended can result in severe
personal injury or death.
These risks may include but not limited to electric shock,
fire, flooding, suction entrapment or severe injury or
property damage caused by a structural failure of the
pump or other system component.
WARNING The pump can produce high levels of
suction within the suction side of the
plumbing system. These high levelof suction can pose a
risk if a person comes within the close proximity of the
suction
openings. A person can be seriously injured by this high
level of vacuum or may become trapped and drown. It is
absolutly critical that the suction plumbing be installed
in accordance with the latest national and local codes for
swimming pools.
For installation of electrical controls at equipment pad (ON/OFF Switches, Timers and Automation Load Center):
CAUTION Install all electrical controls at equipment pad, such as ON/OFF switches, timers and control
systems to allow the operation (startup, shut-down or servicing) of any pump or lter so the
user does not place any portion of his/her body over or near the pump strainer lid, lter lid of
valve closures. This installation should allow the user enough space to stand clear of the lter
and pump during system start-up, shut down or servicing of the system lter.
HAZARDOUS PRESSURE: STAND
CLEAROF PUMPAND FILTER DURING
START UP
Circulation systems operate under
high pressure. When any part of the
circulating system (i.e. locking ring,
pump, lter, valves, etc.) is serviced,
air can enter the system and become pressurized.
Pressurized air can cause the pump housing cover, lter
lid and valves to violently separate which can result in
severe personal injury or death. lter tank lid and strainer
cover must be properly secured to prevent violent
separation. Stand clear of all circulation system
equipment when turning on or starting the pump.
Before servicing equipment, make note of the filter
pressure. Be sure that all controls are set to ensure the
system cannot inadvertently start during service. Turn of
all power to the pump. IMPORTANT: Place lter manual air
relief valve in the open position and wait for all pressure
in the system to be relieved.
Beforestarting thesystem, fullyopen the manualair relief
valve and place all system valves in the “open” position to
allow water to ow freely from the tank and back to the
tank. Stand clear of all equipment and start the pump.
IMPORTANT: Do not close lter manual air relief valve
until all pressure has been discharged from the valve and
a steady stream of water appears. Observe lter pressure
gauge and be sure it is not higher than the pre-service
condition.

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS
GENERAL INSTALLATION INFORMATION
• All work must be performed by a qualied service
professional, and must conform to all national, state
and local codes;
• Install to provide drainage of compartment for elec-
trical components;
• These instructions contain information for a variety
of pump models and therefore some instructions
may not apply to a specic model. All models are in-
tended for use in swimming pool applications. The
pump will function correctly only if is properly sized
to the specic application and properly installed;
• Installing a non-return valve after the pump on the
installation will prevent the impeller from unwinding
and is strongly recommended;
• Sufficient equipotential bonding (min. 4.5mm2
recommended), in accordance with local regulation,
is required on all metal components of the pool
including the pool pump. It is required for electrical
safety as well as to reduce the risk of corrosion.

PUMP INFORMATION
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
lled 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 lling 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 qualied 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 ecien-
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.
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 ve (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.
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.

PUMP INFORMATION
FITTINGS AND VALVES
1. Do not install 90° elbows directly into pump inlet.
2. Flooded suction systems should have gate valves
installed on suction and discharge pipes for main-
tenance, however, the suction gate valve should
be no closer than ve times the suction pipe di-
ameter as described in this section.
3. Use a check valve (non-return valve) in the dis-
charge line when using this pump for any appli-
cation where there is significant height to the
plumbing after the pump.
4. Be sure to install check valves when plumbing in
parallel with another pump. This helps prevent
reverse rotation of the impeller and motor.
ELECTRICAL REQUIREMENTS
1. Install all equipment in accordance with
the National Electrical code and all ap-
plicable local codes and ordinances.
Sufficient equipotential bonding (min. 4.5mm²
recommended), in accordance with local regula-
tion, is required on all metal components of the
pool including the pool pump. It is required for
electrical safety as well as to reduce the risk of
corrosion.
2. A means for disconnection must be incorporated
in the fixed wiring in accordance with the wiring
rules.
3. Do not mount electrical controls directly over
pump.
3.4 - START / OPERATION
Starting the pump
• Fill pump strainer with water to suction pipe level.
• Lubricate the lid Oring with lubricant each time it
is removed.
• Make sure the strainer lid is properly closed before
turning on the pump.
• Energize the motor, the pump will prime. The prim-
ing time depends on the suction lift and distance to
the pool. Five minutes is a reasonable time.
• Pump will not lift more than 2,5 meter. If pump does
not prime, see troubleshooting guide.
• Avoid damage on your pool products by installing
water treatment produts (chlorine/ph/pumps/...)
behind other equipment.
Maintenance
The strainer basket should be weekly removed and cleaned. Never operate the pump without its strainer basket.
