IMPORTANT SAFETY INSTRUCTIONS
WARNING - SUCTION ENTRAPMENT HAZARD
Suction in suction outlets and/or suction outlet
covers which are damaged, broken, cracked,
missing, or unsecured can cause severe injury and/
or death due to the following entrapment hazards:
Hair Entrapment: Hair can become entangled in suction outlet cover.
Limb Entrapment: A limb inserted into an opening of a suction outlet
sump or suction outlet cover that is damaged, broken, cracked, missing,
or not securely attached can result in a mechanical bind or swelling of
the limb.
Body Suction Entrapment: A negative pressure applied to a large
portion of the body or limbs can result in an entrapment.
Evisceration / Disembowelment Entrapment: A negative pressure
applied directly to the intestines through an unprotected suction
outlet sump or suction outlet cover which is damaged, broken, cracked,
missing, or unsecured can result in evisceration / disembowelment
entrapment.
Mechanical Entrapment: There is potential for jewelry, swimsuit,
hair decorations, nger, toe, or knuckle to be caught in an opening of a
suction outlet cover resulting in mechanical entrapment.

• This is an “Unblockable” SOFA.
• Suction cover life is 7 years, the sump wall tting life is 15 years, the rest of the components have 25 year life, cover and all
SOFA components shall be replaced on or before the end of service life.
•The use of adhesives or other attachment methods that prevent access to suction piping or SOFA components is prohibited.
•Please refer to Head Loss Curve, suction head measured at the wall tting.
•This is an unblockable SOFA as marked on the suction cover.
•DO NOT USE POWER TOOLS TO INSTALL FASTENERS. Ensure proper thread engagement to prevent cross-threading.
•Ensure proper atness of installation surface.
• When mud-rings, sump and other components are held in place by the interior surface of the pool, the surface should be free
of deterioration or voids
•Damaged Fasteners shall be replaced with original parts, and must be passitive grade 316 stainless steel. The wall tting shall
be inspected for the presence of any CRACK or material loss. Cracked/damaged mud rings, sumps, or wall ttings shall
be replaced.
•No unauthorized eld modications.
•This product is intended for use on gunite, vinyl, berglass, and roto-molded pools, spas and hot tubs.
•No modication shall be made to SOFA structure or ow path unless the conguration has been certied as a new SOFA.
•Service life begins the month and year in which SOFA components are installed with or without water.
•For winterization remove the cover and plug the inlet.
•Observe cover/grate/fasteners for damage each operational day.
•During installation ensure components and fastener receptacles are clean, free of debris and obstructions.
•Hand-check cover/grate for snugness to the sump/frame/wall tting after installation.
•SOFA installation components with crack, chunks, or pieces broken o, stripped screw holes, brittleness, and/or unusual
discoloration should be replaced.
•The mounting surface or interior surface of the pool should be free of deterioration.
•Start installation of screws by hand to ensure proper thread engagement and to prevent cross-threading.
•Do not exceed the safe ow rating of SOFAs as listed.
•All SOFAs should be installed in accordance with Waterway installation instructions.
•No modication shall be made to SOFA structure or ow path unless new conguration has been certied as a new SOFA.
•SOFA specic ow ratings are not to be exceeded while the pool is open.
•The capacity of secondary circulation system (skimmer, cutters, etc) should not be included when evaluating an individual
suction system ow rating.
•For the ow rating for pools with multiple blockable SOFAs in one body of water without isolation valves: combine all
SOFAs, minus the ow rate of one, if all are not equal use the larger ow rate.
•“Blockable” SOFAs in new pools shall be installed in multiple-SOFA system ONLY.
•“Blockable” SOFAs in existing pools with single SOFA systems shall be installed with an additional anti-entrapment device
or system.
•This SOFA shall be used with Waterway sump or with Waterway mud-ring and eld built sump per attached instructions.
•Unauthorized eld modications will void certication.
•Cover/grate, including fasteners, shall be observed for damage or tampering each operational day.
•The ow rating for pools with single or multiple unblockable SOFAs shall be the combined ow rate of all SOFAs piped together
on one body of water.
•All SOFAs shall not be located on backrests or seats.
Required Tools: Philips screw driver bit and torque wrench. Hand tighten screws. DO NOT use power tools. Torque fasteners to a maximum
of 48 in-lb.

Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction
outlets can result in an increased potential for suction entrapment as described on the previous page.
This tting is rated at 244 GPM when mounted on the oor and 216 GPM when mounted on the wall when
only one port on the center of the sump is used. This tting is rated at 320 GPM when mounted on the oor
and 240 GPM when mounted on the wall when two ports on the sump are used. If the tting is missing or
broken, replace with a tting of equivalent rating or higher. Use of a lower rated suction tting could result in
entrapment of the body which could result in serious injury including drowning.
Do not use or operate pool, spa, or hot tub if this suction tting is missing, broken or not secured per
instructions. The suction tting is intended to prevent entrapment of the body. Use of the spa hot tub with a
missing, broken or improperly secured suction grate may result in serious personal injury including drowning.
When the pool, spa or hot tub is in operation, suction is created at this tting. Users of the spa or hot tub must
be instructed not to come in contact with this tting in such a way as to block its orice. If a user of the spa or
hot tub blocks this tting with his/her body, serious personal injury or drowning may occur.
Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material,
can result in an increased potential for suction entrapment as described on the previous page.
Suction outlet components have a nite life. The cover/grate should be inspected frequently and replaced at
least every seven years, or if found to be damaged, broken, cracked, missing, or not securely attached.
WARNING
Do not exceed the safe ow rate. Do not increase ow through system by increasing pump size or horsepower.
Do not allow children to sit, play or interact with main drains or suction outlet.
In order to remove the suction cover (for service or winterization), using a Phillips-head screw driver remove
the screws. Inspect both the suction cover and suction tting for any cracks or damages.
Any and all broken or missing parts must be replaced prior to starting spa or pool pump. Never operate spa or
pool without drain cover in place and properly axed, death or serious injury can result.
It is imperative to securely attach the suction cover to the wall ttings (use only the original supplied screws
or obtain original replacements). Do not over tighten the screws. Inspection of fasteners and observation for
damaged/tampered with suction ttings is required.
Use 2.5" schedule 40 PVC pipe.

TO REDUCE THE RISK OF ENTRAPMENT HAZARDS:
SAVE THESE INSTRUCTIONS.
• Installation of a vacuum release system,
which relieves entrapping
suction, is recommended.
• SOFA(s) should be chosen so that the
individual suction system ow rate is >
pumping system’s MAX system ow rate.
• Never use a pool or spa if any suction outlet component is damaged,
broken, cracked, missing, or not securely attached.
• Replaced damaged, broken, cracked, missing, brittle, or not securely
attached suction outlet components immediately.
All other applicable National, State, and local codes and requirements shall be followed.
