 S-20 Automatic Skimmer Installation Guide

Suction entrapment dangers include:

Hair Entanglement – 

When the hair tangles or knots in the drain cover, trapping the swimmer underwater.  This hazard is present

when the flow rating of the cover is too small for the pump or pumps.

Limb Entrapment – 

When a limb is sucked or inserted into an opening resulting in a mechanical bind or swelling.  This hazard is

present when a drain cover is missing, broken, loose, cracked or not properly secured.

IMPORTANT WARNINGS AND SAFETY INSTRUCTIONS

 SUCTION ENTRAPMENT HAZARD

Pool and spa pumps produce high levels of suction, which can pose extreme danger if a person comes in close proximity
to an open pool or spa drain or if a drain cover is loose, cracked, broken or missing.

Pool and spa pumps move large volumes of water, which can pose extreme danger if a person’s hair comes in close
proximity to a drain that is not the proper size for the pump or pumps.

Body Entrapment – 

When a portion of the body is held against the drain cover trapping the swimmer underwater.  This hazard

is present when the drain cover is missing, broken or the cover flow rating is not high enough for the pump or pumps.

Evisceration/Disembowelment – 

When a person sits on an open pool (particularly a child wading pool) or spa outlet and

suction is applied directly to the intestines, causing severe intestinal damage.  This hazard is present when the drain cover is
missing, loose, cracked, or not properly secured.

Mechanical Entrapment – 

When jewelry, swimsuit, hair decorations, finger, toe or knuckle is caught in an opening of an outlet

or drain cover.  This hazard is present when the drain cover is missing, broken, loose, cracked, or not properly secured.

Use these fittings only with a pumping system rated for the corresponding flow or less for two (2) inch plumbing.
FAILURE TO DO SO CAN RESULT IN HAIR OR BODY ENTRAPMENT WHICH CAN CAUSE SEVERE

PERSONAL INJURY OR DEATH. If in doubt about the rating of your system, consult a qualified pool or spa professional.
