DO NOT TURN ON THE SOLAR WATER SUPPLY to this equipment until heater is completely
filled with water and all air has been released. If the heater is NOT filled with water when the power
is turned on, damage to the heating coil may result.
For protection against excessive pressures and temperatures, local codes require the installation of a
temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that
maintains periodic inspection of production of listed equipment of materials, as meeting the
requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI

PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS.
All water heaters have a risk of leakage at some unpredictable time. IT IS THE CUSTOMER'S
RESPONSIBILITY TO PROVIDE A CATCH PAN OR OTHER ADEQUATE MEANS, SO THAT
THE RESULTANT FLOW OF WATER WILL NOT DAMAGE FURNISHINGS OR PROPERTY.
WATER HEATER PLACEMENT
