Note: After performing the first maintenance on the Nortec SETC it is possible to
increase or decrease the service period to match water conditions. If the tank, heat
exchanger, and float chamber are relatively clean and free of scale increase the
service period. If there is a lot of scale and it is difficult to remove then reduce the
service period and consider increasing the blow down setting. (See Nortec SETC
