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 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 filter 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 filter control valve position while system pump is running.  Before 

starting system pump, 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) is discharged.  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 pump components.  Strainer cover must be properly secured to pump housing 
with strainer cover lock ring.  Before servicing pool and spa circulation system, all system and pump 
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 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.   

 

 

 

WARNING

 – 

Fire and burn hazard.

  Motors operate at high temperatures and if they are not properly isolated from 

any flammable structures or foreign debris they can cause fires, 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 for burns.

     

 

 

WARNING

 – 

Failure to

 

install according to all defined instructions may result in severe personal injury or death.
