Manual Drain Switch
In addition to software controlled draining of the cylinder the NHTC/PC has a manual drain
switch which can be used to drain the cylinder even if software is not functioning. To drain the
cylinder put the switch into the drain position. For normal operation the switch should be in the
off position.
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.
Caution: Power to the humidifier should always be turned off using the dedicated
external disconnect before removing the door or side panel, or before doing any
service work on the humidifier.
