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.
The 9”x 9”/ 640-479X V fitting is rated at 240 GPM for floor and 208 GPM for wall. If the fitting is missing or
broken, replace with a fitting of equivalent rating or higher. Use of a lower rated suction fitting 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 fitting is missing, broken or not secured per
instructions. The suction fitting 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 fitting. Users of the spa or hot tub must
be instructed not to come in contact with this fitting in such a way as to block its orifice. If a user of the spa or
hot tub blocks this fitting 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 finite 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 flow rate. Do not increase flow 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 fitting 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 affixed, death or serious injury can result.
It is imperative to securely attach the suction cover to the wall fittings (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 fittings is required.

TO REDUCE THE RISK OF ENTRAPMENT HAZARDS:
• Installation of a vacuum release system,
which relieves entrapping
suction, is recommended.
• SOFA(s) should be chosen so that the
individual suction system flow rate is >
pumping system’s MAX system flow 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.
