Output heating capacity is reduced if these heaters are installed on 415V, 400V or 380V 3-ph .
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 3 phases .
3 . All 3 phase indicator lights are lit (not flashing) indicating maximum power draw and maximum
amperage is being drawn .
4 . Flow rate and temperature rise requirements are compatible with the heater specifications .
5 . Verify there is no additional supply of cold water entering the line downstream of the heater .
