ELECTRONIC DRAIN VALVE
The dryers(HX76K~151K) are equipped with an electronic drain valve that automatically
discharges condensate from the dryer. The drain valve and its controls are accessible from
the left side of the dryer. The electronic drain valve has two indicators and a test button to
help verify operation. Pushing the test button causes the drain port to click open. If either
indicator fails to turn on at the proper time, refer to the maintenance section of this manual.
Drain valve operation is controlled by an electronic timer. The drain opening can be set
from 0.5 sec to 10 sec. The drain cycle can be set from 0.5 min to 45 min.
