WARNING - To reduce the risk of entrapment hazards:
o When suction outlets are less than a 18” x 23” equivalent, a minimum of two functioning suction outlets per pump
must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of three feet
(3’) [1 meter] apart, as measured from near point to near point.
o Dual suction outlets shall be placed in such locations and distances to avoid “dual blockage” by a user.
o Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
o The maximum system flow rate shall not exceed the flow rating of any listed (per current revision of ASME/ANSI A112.19.8) suction
outlet cover installed.
o Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
o Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
o In addition two or more suction outlets per pump installed in accordance with latest APSP (formally NSPI) Standards and CPSC
guidelines, follow all National, State, and Local codes applicable.
This vacuum release system is designed to prevent body suction entrapment, but not evisceration.
WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets
can result in an increase potential for suction entrapment as described above.
WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material
can result in an increase potential for suction entrapment as described above.
WARNING – Suction outlet components have a finite life, the cover/grate should be inspected frequently and replaced at
least every ten years or if found to be damaged, broken, cracked, missing, or not securely attached.
WARNING – All suction and discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result
in severe personal injury and/or property damage. All drains and suction outlets MUST have properly installed covers, securely attached using
the screws supplied with the covers. If screws are lost, order replacement parts from your supplier.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate under hazardous pressure during
start up, normal operation, and after pump shut off. Stand clear of circulation system equipment during pump start up. Failure to
follow safety and operation instructions could result in violent separation of the pump housing and cover due to pressure in the
system, which could cause property damage, severe personal injury, or death. Before servicing pool and spa water circulation
system, all system and pump controls must be in off position and filter manual air relief valve must be in open position. Before
starting system pump, all system valves must be set in a position to allow system water to return back to the pool. Do not change
filter control valve position while system pump is running. Before starting system pump, fully open filter manual air relief valve.
Do not close filter manual air relief valve until a steady stream of water (not air or air and water) is discharged.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could result in violent
separation of pump components. Strainer cover must be properly secured to pump housing with strainer cover lock ring. Before
servicing pool and spa circulation system, manual air relief valve must be in open position. Do not operate pool and spa
circulation system if a system component is not assembled properly, damaged, or missing. Do not operate pool and spa
circulation system unless filter air relief valve body is in locked position in filter upper body.
WARNING – Never operate or test the circulation system at more than 40 PSI.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly isolated from any flammable
structures or foreign debris they can cause fires, which may cause severe personal injury or death. It is also necessary to allow the motor to cool
for at least 20 minutes prior to maintenance to minimize the risk of burns.
WARNING – Failure to install according to defined instructions may result in severe personal injury or death.
DEFINITIONS:
Suction Outlet – The term Suction Outlet is a fitting, fitting assembly, cover/grate and related components that provide a means for water to exit the
pool and into the pump circulating system.
Inches of Mercury (in Hg) - A unit for measuring pressure below atmospheric (“suction” or “vacuum”) (1.0 inch Hg = .491 PSI)
Main Drain – See Suction Outlet
PSI – An abbreviation for pounds per square inch.
