13. Refer to PNEG-1650/PNEG-1651 for the dry and cool chart settings that correspond to the model
of dryer being used. Note the settings for initial moisture, moisture removed, approximate dry time,
1 Speed, 2 Speed low and 2 Speed high. Select the line that has the initial starting moisture. These
are the settings that will be referred to during this start-up procedure.
