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 BEFORE USING THIS
PUMP. THESE WARNINGS AND THE OWNER’S MANUAL MUST BE LEFT
WITH THE POOL OWNER.
Do not permit children to use this product.
RISK OF ELECTRICAL SHOCK (For all permanently
installed units intended for use on 15 or 20 ampere,
125 through 240 volt, single phase branch circuits). Connect only to a branch
circuit protected by a ground-fault circuit-interrupter (GFCI). Contact a
qualified electrician if you cannot verify that the circuit is protected by a GFCI.
This unit must be connected only to a supply circuit that is protected by a
ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by
the installer and should be tested on a routine basis. To test the GFCI, push
the test button. The GFCI should interrupt power. Push the reset button.
Power should be restored. If the GFCI fails to operate in this manner, the
GFCI is defective. If the GFCI interrupts power to the pump without the test
button being pushed, a ground current is flowing, indicating the possibility of
an electric shock. Do not use this pump. Disconnect the pump and have the
problem corrected by a qualified 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 or 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 reassembled to its original
integrity.
General Warnings
• Never open the inside of the drive motor enclosure. 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 flow rates; use caution when installing and
programming to limit pumps performance potential with old or questionable
equipment.
• Code requirements for electrical connection differ from country to
country, state to state, as well as local municipalities. Install equipment
in accordance with the National Electrical Code and all applicable local
codes and ordinances.
• 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 (including children) of
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their
safety.
SUCTION ENTRAPMENT HAZARD: STAY OFF
THE MAIN DRAIN AND AWAY FROM ALL SUCTION
OUTLETS!
RELEASE SYSTEM (SVRS) PROTECTION AND DOES NOT PROTECT
AGAINST BODY OR LIMB ENTRAPMENTS, DISEMBOWELMENTS (WHEN
A PERSON SITS ON A BROKEN OR UNCOVERED POOL DRAIN) OR HAIR
ENTANGLEMENTS.
THIS PUMP PRODUCES HIGH LEVELS OF SUCTION AND CREATES A
STRONG VACUUM AT THE MAIN DRAIN AT THE BOTTOM OF THE BODY
OF WATER. THIS SUCTION IS SO STRONG THAT IT CAN TRAP ADULTS
OR CHILDREN UNDER WATER IF THEY COME IN CLOSE PROXIMITY TO
A DRAIN OR A LOOSE OR BROKEN DRAIN COVER OR GRATE.
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 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, STANDARDS AND
GUIDELINES.

TO MINIMIZE THE RISK OF INJURY DUE TO
SUCTION ENTRAPMENT HAZARD:
• A properly installed and secured ANSI/ASME A112.19.8 approved antientrapment 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,
replace with an appropriate certified 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 reconfigure into return inlets.
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.
A clearly labeled emergency shut-off switch for the pump
must be in an easily accessible, obvious place. Make
sure users know where it is and how to use it in case of emergency.
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.
HAZARDOUS PRESSURE: STAND CLEAR OF PUMP
AND FILTER DURING START UP.
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 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
tank and back to the tank. Stand clear of all 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 service 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.
Pumps and replacement motors that are single speed and one (1)
Total HP or greater cannot be sold, offered for sale, or installed
in a residential pool for filtration use in California, Title 20 CCR
sections 1601-1609.
For Installation of Electrical Controls at Equipment
Pad (ON/OFF Switches, Timers and Automation
Load Center)
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.
