Page 2 of 8 DUAL SUBMERGED SUCTION OUTLET ISSQUAREHF REV C 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, finger, toe or knuckle to be caught in an opening of a suction outlet cover resulting in mechanical entrapment. To Reduce the risk of Entrapment Hazards: o 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') [.94 meter] apart, as measured from suction pipe center to suction pipe center. (See Diagram 1 below). If suction outlets are to be located closer then three feet (3') [.94 meter] apart, they shall be located in different planes (i.e., one on the bottom, and one on the vertical wall, or one on each of two separate vertical walls.) (See Diagram 2) o Dual suction fittings 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 ASME/ANSI A112.19.8M-1987, ASME A112.19.8b-2009, APSP-7) suction outlet cover installed. o Keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material. o Never use a Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached. o Prior to each use of the swimming pool and/or spa, observe and replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately. o Remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets. o Two or more suction outlets per pump should be installed in accordance with latest APSP Standards and CPSC guidelines, follow all National, State, and Local codes applicable. o Multiple layers of protection are available including installation of a vent pipe system, a gravity flow system, or a vacuum release system. o 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. o Do not exceed maximum flow rate stated on suction fitting. o Only replace a pump with one with a similar flow curve, avoid a pump with a higher horsepower rating. o To reduce the risk of body entrapment, installation of the field fabricated sumps must be such that the top of the mounted WG1031BHF cover is a minimum of 1 ½" above; and the top of the mounted WG1032BHF cover is a minimum of 1 13/16" above, the finished pool surface over an area larger than 40" on a diagonal.
