This pool pump must be installed by a licensed or certified electrician or a qualified pool installer in accordance with
the 2008 National Electrical Code (“

all applicable local codes and ordinances. The specific section of
NEC
covering your pump may vary depending on your location. Some states, and/or municipalities may not have

in death or serious injury to pool users, installers, or others due to electrical shock, and/or property damage. Always
disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in
death or serious injury to pool users, installers or others (due to electrical shock) and/or property damage.
