HL-Series Tankless Heater
Output heating capacity is reduced on the 480V units if these heaters are installed on 415V or 380V single or three
phase .
Contact the factory to supply this information .
Satisfactory performance of the heater is dependent upon a specific flow rate vs temperature rise capability . If the
desired temperature is not achieved, please verify the following:
1 . Circuit breaker is on and rated for the maximum power draw .
2 . Heater is drawing the proper current for the supply voltage on all the single phase or all the three phases .
3 . All phase indicator lights are lit (not flashing) indicating maximum power draw and maximum
amperage is being drawn .
4 . Flow rate and temperature rise in the water heating process are compatible with the heater specifications .
5 . Verify there is no additional supply of cold water entering the line downstream of the heater .

Product Options
