Using the incorrect voltage may result in fire or electric shock.
Use Extreme Caution if Using With a Solar Pre-Heater
• Using this unit with a solar pre-heater can lead to unpredictable output temperatures and
possibly scalding. If absolutely necessary, use mixing valves to ensure output temperatures do
not get to scalding levels. Do not use a solar pre-heater with the quick-connect multi-system.not
get to scalding levels. Do not use a solar pre-heater with the quick-connect multi-system.
