Power Dry Components
Operation
Power Dry (all models)
The fan is a brushless motor and operated by 13.5
VDC and runs at ~6,000 RPM.
The Power Dry cycle is 50 minutes. When the cycle is
completed, the Clean light comes on.
If the Dry segment of the cycle is interrupted
by opening the door, the control will advise the
consumer to press START and to close the door.
If the consumer does not open the door after the
cycle is complete, the fan will run another 90
minutes. It will not restart if door is opened and
closed, and there will be no indication of this
operation on the control display. The total run time if
door is not opened after the Clean light is cycled on
can be 140 minutes.
Max Dry (ZDT800S and ZDT870S)
Monogram models have both Power Dry and Max
Dry options.
The fan is a brushless motor and rated as dual
speed and running at ~6000 RPM for Power Dry and
~10,000 RPM for Max Dry. ~6-7 VDC @ 6k RPM and
12-14 VDC @ ~10k RPM.
Max Dry operates the same as above.
The Max Dry cycle is 90 minutes and the fan runs at
a maximum speed of ~10,000 RPM. When the cycle
is completed, the Clean light comes on. If the dry
segment of the cycle is interrupted by opening the
door, the control will advise the consumer to press
START and close the door. If the consumer does not
open the door after the cycle is complete, the fan
will run another 90 minutes. During this time the
fan lowers speed to ~6k RPM, and it will not restart
