GRATE AND FRAME OWNER’S MANUAL
Read and keep these instructions for future reference. Follow all instructions in this
owner’s manual and on the equipment. Failure to follow instructions can cause severe
injury and/or death.
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.
• Use two or more suction fitting on each
pump suction line. The suction fittings
shall be separated by a minimum of 3 ft.
(91.44 cm), or if any are located closer they
shall be located on two different planes
(i.e., one on the bottom and one on the vertical wall, or one each on
two separate vertical wall).
• In the event of one suction outlet being completely blocked, the
remaining suction outlets serving that system shall have a flow
rating capable of the full flow of the pump(s) for the specific suction
system.
• Dual suction fittings shall not be located on seating areas or on the
backrest for such seating areas.
• The maximum system flow rate shall not exceed the flow rating of
any listed (per ASME A112.19.8-2007) suction outlet cover installed.
In the event of one suction outlet being completely blocked, the
remaining suction outlets serving the system shall have a flow rating
capable of the full flow of the pump(s).
• Never use a 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 immediately.
• Two or more suction outlets per pump should be installed in
accordance with latest APSP Standards and CPSC guidelines, and
follow all National, State, and Local codes applicable.
• Replace the suction within 7 years from the installation date.
• Installation of a vacuum release system, which relieves entrapping
suction, is recommended.
TO REDUCE THE RISK OF ENTRAPMENT HAZARDS:
USE ONLY GENUINE WATERWAY REPLACEMENT PARTS.

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 fitting is rated at 540 GPM. 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.
