WARN ING

FOR YOUR SAFETY - This product must be serviced by a contractor who is licensed and qualified in pool equipment by the
jurisdiction in which the product will be installed where such state or local requirements exists. In the event no such state or local
requirement exists, the installer or maintainer must be a professional with sufficient experience in pool equipment installation and
maintenance so that all of the instructions in this manual can be followed exactly. Before installing this product, read and follow
all warning notices and instructions that accompany this product. Failure to follow warning notices and instructions may result in
property damage, personal injury, or death. Improper installation and/or operation will void the warranty.

Improper installation and/or operation can create unwanted electrical hazard which can cause serious injury, property damage, or
death.

Connect unit to receptacle protected by a ground fault circuit interrupter (GFCI). Such a GFCI receptacle should be provided by
a qualified installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt
power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the
GFCI interrupts power to the pump without the test button being pushed, a ground current is flowing, indicating the possibility
of an electric shock. Do not use this product. Disconnect the cleaner and have the problem corrected by a qualified service
representative before using.
