DATA TO AVOID PROPERTY DAMAGE AND PERSONAL INJURY
It is extremely important to verify the electrical power supply is the same voltage as the heater being installed. 240 and
120 Volt heaters are not interchangeable. Powering a 208/240/277 Volt unit with 120 Volt supply wires will reduce heater

output by approximately 75%. Powering a 120 Volt unit with 208/240/277 Volt supply wires will destroy the heater and voids
