This came out of my church's baptistry about 3 months ago. It was used for about one year. Installation, operations and service manual is included. Once install the heater is easy to use and most functions are automatic.
Heater must be installed by a Hayward technician. I will not take responsibility if installation is done by anyone other than a certified Hayward tech.
