INSTALLATION, OPERATION, AND MAINTENANCE INFORMATION
It is extremely important you verify the electrical power supply is the same voltage as the heater you are
installing. 240 and 120 Volt heaters are not interchangeable. Powering a 120 Volt unit with 208/240 Volt
supply wires will destroy the heater and voids all warranties.
