1.Turn the dial setting knob to “5,” which is within the normal range. During the next 24-48 hours it may be necessary to adjust the dial for more or less humidity, depending on your personal comfort and home’s requirements. Refer to the “Operation Guide” (Table 1).

2.During the coldest portion of the first heating season, minor adjustments may be necessary. This is dependent upon your individual home construction, refer to the “Operation Guide” (Table 1).
