Hazards Related to Suction Entrapment:

Stay away from all suction outlets and the main drain. This pump is not equipped with a Safety Vacuum Release System (SVRS). Prevent your body or hair from being sucked by the water pump inlet.

The pump produces strong vacuum and high suction. Adults and children can be trapped underwater near drains with loose or broken covers. Missing, cracked, or broken drain covers can cause limb entrapment, hair entanglement, body entrapment, evisceration, and/or death.

Causes of suction at drains and outlets:

• Limb Entrapment: Occurs when a limb is sucked into an opening due to a broken, loose, or improperly fastened drain cover.
• Hair Entanglement: Occurs when a swimmer's hair gets tangled in the drain cover, trapping them underwater. This can happen if the cover's flow rating is too low for the pump.
• Body Entrapment: Occurs when a portion of a swimmer's body is trapped under the drain cover, especially if the cover is damaged, missing, or not rated for the pump.
• Evisceration/Disembowelment: Suction from an open pool or spa outlet can cause severe intestinal damage, particularly if the drain cover is missing, loose, cracked, or not properly secured.
• Mechanical Entrapment: Occurs when jewelry, swimsuit, hair decorations, fingers, toes, or knuckles get caught in an outlet or drain cover that is missing, broken, loose, cracked, or not properly secured.

NOTE: Suction plumbing must be installed according to the latest local and national codes.

Reducing Injury Risks from Suction Entrapment Hazards:

• Each drain must have an ANSI/ASME A112.19.8 approved anti-entrapment suction cover.
• Suction covers should be installed a minimum of three (3) feet apart.
• Regularly check all covers for cracks, damage, and weathering.
• Replace covers if they become loose, cracked, damaged, broken, or missing.
• Replace drain covers as necessary, as they deteriorate over time.
• Avoid getting close to any suction cover, pool drain, or outlet with your hair, limbs, or body.
• Suction outlets can be disabled or reset into return inlets.

WARNING: High suction levels can cause serious injury or drowning. Swimming pool suction plumbing must be installed according to the latest national and local codes.

WARNING: An emergency shut-off switch for the pump should be clearly identified and located in a highly visible location. Ensure all users know its location and how to use it.

The Virginia Graeme Baker (VGB) Pool and Spa Safety Act establishes new requirements for commercial pools and spas.

On or after December 19, 2008, commercial pools and spas must use:

• A multiple main drain system without isolation capability with suction outlet covers complying with ASME/ANSI A112.19.8a, and either:
  • Safety vacuum release systems (SVRS) that meet ASME/ANSI A112.19.17 or ASTM F2387, or
  • Suction-limiting vents that have been properly designed and tested, or
  • System for shutting off pumps automatically.

Pools and spas constructed before December 19, 2008, with a single submerged suction outlet, must use a suction outlet cover that meets ASME/ANSI A112.19.8a or either:

• (A) A SVRS compatible to ASME/ANSI A112.19.17 and/or ASTM F2387, or
• (B) Suction-limiting vents that have been properly designed and tested, or
• (C) System for shutting off pumps automatically, or
• (D) Submerged outlets can be disabled, or
• (E) Reconfiguration of suction outlets into return inlets is required.

Information about Installation:

• Work must be performed by a qualified service professional in accordance with national, state, and local regulations.
• Ensure electrical components are properly drained.
• This manual covers several pump models; some information may not apply to a specific model. All models are for swimming pool use. Proper sizing and installation ensure correct function.

WARNING: Improper pump size, installation, or use can result in serious personal injury or death, including electric shocks, fires, flooding, suction entrapment, and property damage.

Pumps and replacement motors that are single speed and one (1) Total HP or greater cannot be sold, offered for sale, or installed in a residential pool for filtration use in California (Title 20 CCR sections 1601-1609).

CAUTION: Install electrical controls at the equipment pad (ON/OFF switches, timers, automation load centers). This prevents users from placing their bodies near pump or filter components during operation. Ensure users can stand far enough away from the filter and pump during system start-up, shutdown, or servicing.

DANGER: Keep the filter and pump away from your body when starting up. Air entering the system during servicing can pressurize it, causing components like the pump housing cover or filter lid to separate violently. Secure the strainer cover and filter tank lid to prevent separation. Keep circulation equipment clear of you during operation. Note the filter pressure before servicing and ensure pump controls cannot start inadvertently.

IMPORTANT: Ensure the filter manual air relief valve is open and wait for all pressure to be released. Open all system valves to the "open" position before starting. Stand clear of equipment. If filter pressure is higher than pre-service, do not close the manual air relief valve until all pressure is released and a steady stream of water appears.

Location:

• Do not place the pump within an outer enclosure or underneath the skirt of a hot tub or spa, unless marked accordingly.
• Ensure the pump is mechanically secured to the equipment pad.
• Install the pump as close to the pool or spa as possible to reduce friction loss and improve efficiency. Use short, direct suction and return piping.
• Maintain a minimum of 5' (1.5 m) between the inside wall of the pool/spa and any other structures. For Canadian installations, maintain a minimum of 9.8' (3 m).
• Install the pump at least 3' (0.9 m) away from the heater outlet.
• Do not install the self-priming pump more than 8' (2.6 m) above the water level.
• Choose a well-ventilated location protected from excess moisture.
• Allow at least 3" clearance from the rear of the motor and 6" from the top of the control pad for maintenance and repair.

Piping:

• The piping diameter on the intake should be the same or larger than the discharge.
• Shorter piping on the suction side is preferable.
• A valve on both suction and discharge lines is recommended for easy maintenance.
• Any valve, elbow, or tee in the suction line should be at least five (5) times the suction line diameter away from the pump's suction port. For example, a 2" pipe requires 10" of straight line before the suction port.

Fittings and Valves:

• 90° elbows directly into pump intake & discharge are NOT allowed.
• Installing gate valves on suction and discharge pipes is important for maintenance. The suction gate valve should be placed no closer than five times the diameter of the suction pipe.
• A check valve in the discharge line is highly recommended, especially where there is significant plumbing height after the pump.
• Install check valves when plumbing in parallel with another pump to ensure proper functioning and prevent reverse rotation of the impeller and motor.
