WARNING

 – 

To reduce risk of injury, do not permit children to use or climb on this product.  Closely supervise children 

at all times.  Components such as the filtration system, pumps, and heaters must be positioned to prevent children from using them as a 
means of access to the pool.

 

 

 

CAUTION

 – 

This pump is intended for use on permanently installed swimming pools and may also be used with hot tubs 

and spas if so marked.  Do NOT use with storable pools.  A permanently installed pool is constructed in or on the ground or in a 
building such that it cannot be readily disassembled for storage.  A storable pool is constructed so that it is capable of being readily 
disassembled for storage and reassembled to its original integrity.  
 
Though this product is designed for outdoor use, it is strongly advised to protect the electrical components from the weather.  Select a 
well-drained area, one that will not flood when it rains.  It requires free circulation of air for cooling.  Do not install in a damp or non-
ventilated location.  If installed within an outer enclosure or beneath the skirt of a hot tub or spa, adequate ventilation and free circulation 
of air must be provided to prevent overheating of the motor. 
 

 

WARNING

 – 

Pool and spa components have a finite life.  All components should be inspected frequently and replaced at 

least every ten years, or if found to be damaged, broken, cracked, missing, or not securely attached. 

Basic safety precautions should always be followed, including the following: Failure to follow instructions may 
result in injury.
