WARNING When using two or more suction ttings on a common suction line, suctions must be separated by

a minimum of 3 ft or they must be located on two dierent planes (i.e., one on oor and one on the

wall).

WARNING WARNING: DO NOT locate suction outlets on seating areas or on backrests for such seating areas.

NOTICE Attention Installer: This manual contains important information about the installation, operation

and safe use of this product. Before installing this product, read and follow all warning notices and

instructions which are included. This information should be given to the owner and/or operator of

this equipment.

WARNING To reduce the risk of drowning from hair and body entrapment, install suction ttings with a marked

ow rate in gallons per minute that exceeds the ow rate of your system by at least 25%. Always

use multiple suction outlets. If the tting/cover breaks, is damaged, or is missing, shut the system

down immediately. Do not use the system until damaged parts have been replaced.

WARNING Keep hair and clothing a minimum of 12 inches from all suction ttings and drains at all times.

Persons with long hair should secure hair to a minimal length or wear swimming cap. Children

should never be left unattended at any time in a swimming pool, spa, or bathtub. Be sure the

temperature of the water never exceeds the manufacturer’s recommendations.

NOTICE To reduce the risk of injury, installation and service should be done by a qualied Pool Service

Professional, certied electrician or authorized CMP representative.

NOTICE NOTE: In the event that one suction outlet is completely blocked, the remaining suction outlet(s)

serving that system MUST have a ow rating capable of the full ow of the pump(s) for the specic

suction system.

NOTICE Increasing size of the pump may increase ow rate of suction beyond rated safety limits causing

entrapment or death.

CAUTION Hair or body parts blocking the spa or pool suctions may become trapped and held against the

suction tting. Entrapment against the suction ttings can result in drowning or other severe injury.

Never sit on or lean up against suction ttings. Never exceed the maximum allowable ow rate

stated on the suction tting. The suction tting and fasteners should be inspected for damage or

tampering before use. Missing, broken, or cracked suction ttings shall be replaced. Loose suction

ttings shall be reattached or replaced before use of this facility.
