WARNING
–
To Reduce the risk of Entrapment Hazards:
When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per
drive must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum
of three feet (3’) [0.91 meter] apart, as measured from near point to near point.
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
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 values shown in the “Pipe Sizing Chart” found below.
Never use 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.
In addition to two or more suction outlets per drive installed in accordance with latest IAF (formerly NSPI)
standards and CPSC guidelines, follow all national, state, and local codes applicable.
Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING
–
Hazardous Pressure.
Pool and spa water circulation systems operate under hazardous
pressure during start-up, normal operation, and after drive shut-off. Stand clear of circulation system equipment
during drive start-up. Failure to follow safety and operation instructions could result in violent separation of the
drive housing and cover due to pressure in the system, which could cause property damage, severe personal injury,
or death. Before servicing pool and spa water circulation system, all system and drive controls must be in off
position and filter manual air relief valve must be in open position. Before starting system drive, all system valves
must be set in a position to allow system water to return back to the pool. Do not change filter control valve position
while system drive is running. Before starting system drive, fully open filter manual air relief valve. Do not close
filter manual air relief valve until a steady stream of water (not air or air and water mix) is discharged from the valve.
All suction and discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result in
severe personal injury and/or property damage.
WARNING
–
Separation Hazard.
Failure to follow safety and operation instructions could result in violent
separation of drive components. Strainer cover must be properly secured to drive housing with strainer cover lock
ring. Before servicing pool and spa circulation system, all system and drive controls must be in off position and filter
manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system
component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless
filter manual air relief valve body is in locked position in filter upper body. All suction and discharge valves MUST be
OPEN when starting the circulation system. Failure to do so could result in severe personal injury and/or property
damage.
WARNING
– Never operate or test the circulation system at more than 50 PSI maximum.
WARNING
– Failure to
install according to defined instructions may result in severe personal injury or death.
