Pentair Water Pool and Spa®
PUMP WARNING AND SAFETY INSTRUCTIONS
For Pool and Spa Pumps (Non SVRS Pumps)
(Pentair Water Pool and Spa®, Sta-Rite®, and Pentair Pool Products®)
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 pool or spa 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 flow rating of the cover is too small for the pump or pumps.
Body Entrapment: When a portion of the body is held against the drain cover trapping the swimmer underwater.
This hazard is present when the drain cover is missing, broken or the cover flow 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, swimsuit, hair decorations, finger, toe or knuckle is 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.
NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN ACCORDANCE WITH THE LATEST NATIONAL
AND LOCAL CODES FOR SWIMMING POOLS, SPAS AND HOT TUBS, INCLUDING NSPI STANDARDS AND
CPSC GUIDELINES.
TO MINIMIZE THE RISK OF INJURY DUE TO SUCTION ENTRAPMENT HAZARD:
•
Pools and spas should utilize a minimum of two drains per pump.
•
A properly installed and secured ANSI/ASME A112.19.8 approved anti-entrapment
suction cover must be used for each drain.
•
Each suction cover must be installed at least three (3’) feet apart, as measured from the
nearest point to nearest point.
•
Regularly inspect all covers for cracks, damage and advanced weathering.
•
If a cover becomes loose, cracked, damaged, broken or is missing, close the pool or
spa immediately, shut off the pump, post a notice and keep the pool or spa closed until
an appropriate certified cover is properly installed.
•
Replace drain covers as necessary. Drain covers deteriorate over time due to exposure
to sunlight, pool chemicals and weather.
•
Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or
outlet.
•
Disable suction outlets or reconfigure into return inlets.
A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must be in an
easily accessible, obvious place near the pool or spa. Make sure bathers know where it is and
how to use it in case of emergency.

Pentair Water Pool and Spa®
PUMP WARNING AND SAFETY INSTRUCTIONS
For Pool and Spa Pumps (Non SVRS Pumps)
(Pentair Water Pool and Spa®, Sta-Rite®, and Pentair Pool Products®)
The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates new requirements for owners and
operators of commercial swimming pools and spas.
Commercial pools or spas constructed on or after December 19, 2008, shall utilize:
(A) A multiple main drain system without isolation capability with suction outlet covers that meet ASME/ANSI
A112.19.8a Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs and either:
(i) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured Safety Vacuum
Release systems (SVRS) for Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading
Pool Suction Systems and/or ASTM F2387 Standard Specification for Manufactured Safety Vacuum
Release Systems (SVRS) for Swimming pools, Spas and Hot Tubs or
(ii) A properly designed and tested suction-limiting vent system or
(iii) An automatic pump shut-off system.
Commercial pools and spas constructed prior to December 19, 2008, with a single submerged suction outlet
shall use a suction outlet cover that meets ASME/ANSI A112.19.8a and either:
(A) A SVRS meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
(B) A properly designed and tested suction-limiting vent system, or
(C) An automatic pump shut-off system, or
(D) Disabled submerged outlets, or
(E) Suction outlets shall be reconfigured into return inlets.
For Installation of Electrical Controls at Equipment Pad
(ON/OFF Switches, Timers and Automation Load Center)
servicing of the system f
Install all electrical controls at equipment pad, such as on/off switches, timers, and control systems,
etc. to allow the operation (startup, shut-down, or servicing) of any pump or filter so the user does
not place any portion of his/her body over or near the pump strainer lid, filter lid or valve closures.
This installation should allow the user enough space to stand clear of the filter and pump during
system start-up, shut down or servicing of the system filter.
HAZARDOUS PRESSURE: STAND CLEAR OF PUMP AND FILTER DURING START-UP
Pool and spa circulation systems operate under high pressure. When any part of the circulating
system (i.e. locking ring, pump, filter, valves, etc.) is serviced, air can enter the system and become
pressurized. Pressurized air can cause the pump housing cover filter lid and valves to violently
separate which can result in severe personal injury or death. Filter 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 up pump.
Before servicing pool and spa equipment, make note of the filter pressure. Be sure that all controls are set to
ensure the system cannot inadvertently start during service. Turn off all power to the pump.
IMPORTANT: Place filter manual air relief valve in the open position and wait for all pressure in the
system to be relieved.
Before starting the system, fully open the manual air relief valve and place all system valves in the “open”
position to allow water to flow freely from the pool and spa back to the pool or spa. Stand clear of all pool and
spa equipment and start the pump.
IMPORTANT: Do not close filter manual air relief valve until all pressure has been discharged from the
valve and a steady stream of water appears. Observe filter pressure gauge and be sure it is not higher than
the pre-service condition.

General Installation Information
•
All work must be performed by a qualified pool professional, and must conform to all national,
state, and local codes.
•
Install to provide drainage of compartment for electrical components.
•
These instructions contain information for a variety of pump models and therefore some
instructions may not apply to a specific model. All models are intended for use in swimming
pool applications. The pump will function correctly only if it is properly sized to the specific
application and properly installed.
Pumps improperly sized or 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
be 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.
The pump can produce high levels of suction within the suction side of the plumbing system.
These high levels of 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 absolutely critical that the suction plumbing be installed
in accordance with the latest national and local codes for swimming pools.

pages ii-vi.
Electrical Requirements and Wiring
WARNING — Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in
accordance with the National Electrical Code and all applicable local codes and ordinances. Improper
installation will create an electrical hazard which could result in death or serious injury to pool users,
installers, or others due to electrical shock, and may also cause damage to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump.
Failure to do so could result in death or serious injury to serviceman, pool users or others due to
electric shock.
Wiring Installation
1. Be sure all electrical breakers and switches are turned off before wiring motor.
2. Be sure that the wiring voltage matches the motor voltage (230 VAC or 115 VAC). If they do not match, the
motor can overheat.
3. Choose a wire size from the Chart 1. When in doubt use a heavier gauge (larger diameter) wire. Heavier
gauge will allow the motor to run cooler and more efficient.
4. Be sure all electrical connections are clean and tight.
5. Cut wires to the appropriate length so they do not overlap or touch when connected to the terminal board.

Maintenance
This section describes how to maintain the SuperFlo® pump.
The Pump Strainer Basket
This unit, sometimes referred to as the ‘Hair and Lint Pot’, is the unit in front of the volute. Inside the chamber
is the basket which must be kept clean of leaves and debris at all times. View basket through the ‘See Through
Lid’ to inspect for leaves and debris.
Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint
pot basket at least once a week. A clogged basket reduces the efficiency of the filter and heater and puts added
stress on the pump motor.
Cleaning the Pump Strainer Basket
WARNING — DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in
the strainer pot. Pumps operated in these circumstances may experience a build up of vapor pressure
and may contain scalding hot water. Opening the pump may cause serious personal injury. In order
to avoid the possibility of personal injury, make sure the suction and discharge valves are open and
strainer pot temperature is cool to touch, then open with extreme caution.
CAUTION — To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer
and skimmer baskets regularly.
1. Turn off motor.
2. Relieve pressure in the system.
3. Turn the clamp and lid in a counter-clockwise direction until it stops.
4. Turn the clamp and lid set to remove the clamp and lid.
5. Put the debris from the basket into the trash and rinse the basket. Replace the basket if cracked.
6. Replace the basket. Be sure to align the slot in the basket with the rib in the volute, see Figure 2.
7. Fill the pump pot and volute up to the inlet port with water.
8. Clean the cover, cover O-ring, and sealing surface of the pump pot. Grease the O-ring with a silicone
based lubricant.

CAUTION — DONOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump
will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water
level in your pool (half way up skimmer opening). If the water level falls below the skimmer opening,
the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting
in a damaged seal. Continued operation in this manner could cause a loss of pressure, resulting in
damage to the pump case, impeller and seal, and may cause property damage and personal injury.
Priming the Pump
1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to
prime the pump.
a. Remove the pump lid plastic clamp. Remove the pump lid.
b. Fill the pump strainer pot with water.
c. Reassemble the pump cover and plastic clamp onto the strainer pot. The pump is now ready to prime.
d. Open the air release valve on the filter, and stand clear of the filter.
e. Turn on the switch or time clock.
f.
When water comes out of the air release valve, close the valve. The system should now be free of air
and recirculating water to and from the pool.
2. For 2-speed pumps:
a. Pump should run on high-speed for priming.
b. The pump should not run longer than 8 minutes before priming is achieved.
