Dip switches are factory set. Failure to maintain factory settings may adversely
affect performance and warranty coverage.

Do not adjust the S2 dip switch. These must be left in the factory default position, or
the unit will not operate properly. The S2 dip switch No. 6 is factory-adjusted to the
"ON" position for the auxiliary codes G1 and H0. Change it to the "OFF" position when
replacing the control board. This does not affect the product performance but prevents
cloudy ice even in poor water quality areas.
