counterclockwise to reduce.
NOTE: Knobs are located behind the dryer cover:
H = Heat
M = Motor
R = Range
• Heat
– Air temperature (turn off to reduce energy
costs). When heat is off, the dryer is the same as the
XleratorEco version dryer.
• Motor
– Air flow speed (lower to reduce energy costs).
• Range
– The distance the sensor under the dryer,
used to recognize hands, will work.
