6.1.6 Nite Care Mode
The NU-543 may be configured to allow the DC ECM motor to continue to run at a lower rate with the sliding
window closed allowing the workzone interior to be continually HEPA filtered. If the Nite Care mode is configured,
the blower must be on (green LED above blower key will blink) and the window closed for it to be activated. In
addition, the fluorescent light will be disabled. The UV light may be turned on if installed.

alarm for 15 minutes initially then will start the ring back function again
