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 fi nite life, the cover/grate should be inspected fre-
quently and replaced at least every ten years or if found to be damaged, broken, cracked, missing, or
not securely attached.
WARNING – 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. All drains and suction
outlets MUST have properly installed covers, securely attached using the screws supplied with the
covers. If screws are lost, order replacement parts from your supplier.
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 start up. Failure to follow safety
and operation instructions could result in violent separation of the pump 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 pump controls must be in off position and fi lter manual air relief valve
must be in open 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 fi lter
control valve position while system pump is running. Before starting system pump,
fully open fi lter manual air relief valve. Do not close fi lter manual air relief valve
until a steady stream of water (not air or air and water) is discharged.
WARNING – Separation Hazard. Failure to follow safety and operation instruc-
tions could result in violent separation of pump components. Strainer cover must be
properly secured to pump housing with strainer cover lock ring. Before servicing
pool and spa circulation system, 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 fi lter air relief valve body is in locked position in fi lter upper body.
WARNING – Never operate or test the circulation system at more than 40 PSI.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly
isolated from any fl ammable structures or foreign debris they can cause fi res, which may cause severe
personal injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to
maintenance to minimize the risk of burns.
WARNING – Failure to install according to defi ned instructions may result in severe personal injury or
death.
