Note: After performing the first maintenance on the 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 SETC Configuration)
