Auxiliary Drain Switch
In addition to software controlled draining of the tank , the NHRS has a manual drain switch
which can be used to drain the tank even if software is not functioning. To drain the tank,
put the switch into the drain position. For normal operation the switch should be in the off
position. If the unit has multiple tanks, the switch will have both “Tank A” and “Tank B” settings.
This allows single-tank draining.
Door Interlock Switch
The door interlock switch cuts power to the contactor when the door is removed. It is an
additional safety device intended to prevent the possibility of service technicians coming into
contact with live electrical wiring while working on the humidifier. Pull the switch out with door
off to override.
