WARNING
- Read and follow all instructions in this owner’s manual and on the equipment. Failure to
follow instructions can cause severe injury and/or death.
WARNING
– Suction Entrapment Hazard.
Suction in suction outlets and/or suction outlet covers which are, damaged, broken, cracked, missing, or unsecured can cause
severe injury and/or death due to the following entrapment hazards:
Hair Entrapment- Hair can become entangled in suction outlet cover.
Limb Entrapment- A limb inserted into an opening of a suction outlet sump or suction outlet cover that is damaged, broken,
cracked, missing, or not securely attached can result in a mechanical bind or swelling of the limb.
Body Suction Entrapment- A negative pressure applied to a large portion of the body or limbs can result in an entrapment.
Evisceration/ Disembowelment - A negative pressure applied directly to the intestines through an unprotected suction outlet
sump or suction outlet cover which is, damaged, broken, cracked, missing, or unsecured can result in evisceration/
disembowelment.
Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, finger, toe or knuckle to be caught in an
opening of a suction outlet cover resulting in mechanical entrapment.
WARNING
- To Reduce the risk of Entrapment Hazards:
o
When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per pump must be
installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of three feet (3’) [1 meter]
apart, as measured from near point to near point.
o
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
o
Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
o
The maximum system flow rate shall not exceed the flow rating of as listed on Table 2.
o
Never use Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
o
Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
o
In addition two or more suction outlets per pump installed in accordance with latest ASME, APSP Standards and CPSC
guidelines, follow all National, State, and Local codes applicable.
o
Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING
– Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa
from the suction outlets can result in an increase potential for suction entrapment as described above.
WARNING
– Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper
and other material can result in an increase potential for suction entrapment as described above.
WARNING
– Suction outlet components have a finite life, the cover/grate should be inspected
frequently and replaced at least every ten years or if found to be damaged, broken, cracked, missing, or not
securely attached.
CAUTION
– Components such as the filtration system, pumps and heater must be positioned so as to
prevent their being used as means of access to the pool by young children.
WARNING
– Never operate or test the circulation system at more than 40 PSI.
CAUTION
– All electrical wiring MUST be performed by a qualified professional, and MUST conform to
local codes and regulations.
WARNING
– Never change the filter control valve position while the pump is running.
WARNING
– Hazardous Pressure.
Pool and spa water circulation systems operate under hazardous pressure
during start up, normal operation, and after pump shut off. Stand clear of circulation system equipment during pump start up.
Failure to follow safety and operation instructions could result in violent separation of the pump housing and cover, and/or
filter housing and clamp 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 pump controls must be in off position. Before starting
system pump, 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 pump is running.
