a. CAUTION! DO NOT EXCEED THE MAXIMUM ALLOWABLE FLOW RATE: 28 gallons per minute (1,680 gallons per hour) for PSF-2021A and 34 gallons
per minute (2,040 gallons per hour) for PSF-2021B.
b. Carefully observe and inspect the suction outlet fitting for damage and tampering. Missing, broken or cracked suction outlet fitting must be replaced before
each use of your pool.
c. Loose suction outlet fitting should be reattached or replaced before each use of your pool.
d. Remove and store the suction outlet fitting assembly if temperatures are expected to fall below 32°F (0°C).
• PSF-2021A and PSF-2021B Suction Outlet Fittings are certified by IAPMO in accordance with the ASME/ANSI/APSP/ICC-16 2017 Suction Fittings for Use in
Swimming Pools, Wading Pools, Spas, and Hot Tubs.
• This is a submerged suction outlet fitting for use with aboveground swimming pool.
• For dual drain only. TWO outlet fittings are used for each pump.
• Do not locate these suction outlet fittings on sitting areas or on the backrest for such seating area.
• Install this outlet fittings at location recommended by the pool manufacturer. Maximum height 1.8 m from the ground.
• The maximum allowable flow rate of PSF-2021A is 28 gallons per minute (1,680 gallons per hour) and PSF-2021B is 34 gallons per minute (2,040 gallons per hour).
• Connection hose:
a. Model PSF-2021A is to be connected with 1 ¼” (31.8mm) diameter hose.
b. Model PSF-2021B is to be connected with 1 ½” (38.1mm) diameter hose.
• The suction outlet fitting is to be mounted at the suction outlet fitting opening as specified by the manufacturer of the aboveground pool. The diameter of this
opening should be within the range of 1.875” (47.625mm). Refer to the following diagram for detailed assembly instructions:

Important Information about Suction Outlet Fitting Assembly (SOFA)
WARNING! This is a BLOCKABLE VGBA Suction Outlet that must ONLY be installed in a multiple VGBA Suction Outlet system.
• When installing and using this equipment, basic safety precautions shall always be followed, including the following: IMPORTANT SAFETY INSTRUCTIONS.
• READ, FOLLOW, AND UNDERSTAND ALL INSTRUCTIONS AND WARNINGS.
• Any modification that increases the flow rate of the circulation system shall require reevaluation of the cover/grate and sump to ensure that the flow rating of the
Suction Outlet Fitting Assembly (SOFA) is not exceeded.
• All SOFA components must be replaced in every 3 years.
• According to Section 6.2.2 of
《
ANSI/APSP/ICC-16 2017
》
, the Suction Outlet Fittings of this pump are categorized as blockable type.
• Any field modifications made to a SOFA not authorized by the manufacturer’s installation instructions shall void the SOFA certification.
• No modification shall be made to a SOFA structure or flow path unless the new configuration has been certified as new SOFA.
• Cover/grates and all other SOFA components shall be replaced at or before the end of their service life (3 years) and that service life begins the month and
year in which a SOFA component is installed with or without water.
• Cover/grate, including fasteners, shall be observed for damage or tampering each operational day.
• Missing, broken, or cracked cover/grates shall be replaced before bathers are allowed to use the pool.
• Loose cover/grates and associated components shall be reattached before bathers are allowed to use the pool.
• SOFA components and fastener receptacles shall be clean and free of debris or obstructions during installation of cover/grate and fasteners.
• It is required to hand-check cover/grate for snugness to the sump/frame after installation.
• Regular visual and hand-check of SOFA components is required to ensure there is no color change, cracks, deformation, missing parts or components with
pieces broken off. Replace the SOFA if there is color change, cracks, deformation, missing parts or broken pieces.
• The General Certificate of Conformity (GCC) is available at the following website: www.polygroupstore.com.
Installation Requirements and Limitations for Suction Outlet Fitting Assembly (SOFA)
• All SOFAs shall be installed in accordance with the manufacturer’s installation instructions, or for RDP SOFAs, in accordance with the registered design
professional’s engineering plans.
• No modification shall be made to a SOFA structure or flow path unless the new configuration has been certified to the original SOFA.
• The performance-based flow ratings for all SOFA(s) are tested with standard
《
ANSI/APSP/ICC-16 2017
》
. These flow limits are designed to prevent
suction entrapment.
• Compliance with this standard requires that these SOFA-configuration specific flow ratings NOT be exceeded at any time the pool is open to bathers.
• Compliance with this standard requires selecting and installing a SOFA, or combination of SOFAs, such that the resulting individual suction system flow rating
is greater than the pumping system’s maximum system flow rate.
• The flow rating for pools with multiple, blockable SOFAs piped together in one body of water without isolation valves shall be determined by combining the
flow rating of all SOFAs, minus the flow rating of one. If the flow ratings of all SOFAs are not equal, subtract the flow rating of the SOFA with the highest
flow rating. SOFAs are not intended for single application and are not unblockable. Flow rating: PSF-2021A: 28 GPM; PSF-2021B: 34 GPM.
• The cover/grate for this pump is “For Use in Storable Pool Only”. The cover/grates, when installed, shall not protrude more than 2 inches (51 mm) from the
finished surface of the pool in which the SOFA is installed.
• When used in multiple-outlet systems, cover/grates marked blockable shall be arranged such that the two outermost sumps/frames shall have a minimum
separation of three feet, measured center-to-center. If they are to be installed closer than three feet center-to-center, they shall be located on two different
planes, i.e., one SOFA shall be located on the pool floor, and one shall be located on a vertical wall, or one SOFA shall be located on each of two separate walls.
• The Suction Outlet Fitting Assembly (SOFA) has been certified to the consumer product safety rule applicable to SOFAs, which is covered in the Virginia
Graeme Baker Pool and Spa Safety Act
