A. SAFETY INSTRUCTIONS & PRECAUTIONS
IMPORTANT SAFETY INSTRUCTIONS.
READ AND FOLLOW ALL INSTRUCTIONS
ALWAYS PLUMB AND INSTALL ALL SUCTION FITTINGS ACCORDING TO ALL
BUILDING CODES THAT APPLY IN YOUR AREA.
WARNING
When using two or more suction fittings on a common suction line, suctions must be separated by a minimum of 3 ft or they must be located on two different planes (i.e., one on floor 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 fittings with a marked flow rate in gallons per minute that exceeds the flow rate of your system by at least 25%. Always use multiple suction outlets. If the fitting/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 fittings 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
NOTICE
To reduce the risk of injury, installation and service should be done by a qualified Pool Service
Professional, certified electrician or authorized CMP representative.
NOTE: In the event that one suction outlet is completely blocked, the remaining suction outlet(s) serving that system MUST have a flow rating capable of the full flow of the pump(s) for the specific suction system.
NOTICE Increasing size of the pump may increase flow 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 fitting. Entrapment against the suction fittings can result in drowning or other severe injury.
Never sit on or lean up against suction fittings. Never exceed the maximum allowable flow rate stated on the suction fitting. The suction fitting and fasteners should be inspected for damage or tampering before use. Missing, broken, or cracked suction fittings shall be replaced. Loose suction fittings shall be reattached or replaced before use of this facility.
