NOTES TO THE ELECTRICIAN:
Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug to rein-
forcing rod or mesh. Connect a No. 8 AWG solid copper bonding wire to the grounding lug provided on the
heater and to all metal parts of swimming pool or spa, and to all electrical equipment, metal piping (except
gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool or spa. IMPORTANT -Refer-
ence NEC codes for all wiring standards including, but not limited to, grounding, bonding and other general
wiring procedures.
Hair Entrapment- Hair can become entangled in suction outlets.
Limb Entrapment- A limb inserted into an opening of a suction outlet 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 differential pressure applied to a large portion of the body or limbs can
result in an entrapment.
Evisceration/ Disembowelment - A vacuum 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).
Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, fi nger, toe or knuck-
le to be caught in an opening of a suction outlet or suction outlet cover resulting in mechanical entrap-
ment.
WARNING - To reduce the risk of entrapment hazards:
• The maximum system fl ow rate shall not exceed the fl ow rating of any listed (per current revision of
ASME/ANSI A112.19.8) suction outlet cover installed.
• Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not
securely attached.
• Replace damaged, broken, cracked, missing, or not securely attached suction outlet components imme-
diately.
• Install two or more suction outlets per pump in accordance with latest APSP (formally NSPI) Standards
and CPSC guidelines. Follow all applicable National, State, and Local codes.
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 fol-
lowing entrapment hazards:
• 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. fl oor or wall), must be installed a minimum of three feet (3') [1 meter]
apart, as measured from near point to near point.
• Dual suction outlets shall be placed in such locations and distances to avoid "dual
blockage" by a user.
• Dual suction fi ttings shall not be located on seating areas or on the backrest for
such seating areas.
