MHB Service Reminder
The MHB controller includes a service reminder which will shut down the MHB after 800 hours
of operation. At that time the LCD display inside the control box will display the message shown
in Figure 46: MHB Service Reminder. When the service reminder occurs the media must be
inspected and replaced if it is heavily soiled and all the maintenance indicated in Maintenance
Schedule on page 62 must be performed. Nortec is not responsible for any damages resulting
from, or attributed to not performing required maintenance. (see Manufacturer’s Warranty).
After the maintenance has been performed the service reminder must be reset by
simultaneously pressing / holding button 1 and 4 for three seconds.

Warning
If the Nortec MH Series is insufficiently maintained microbials which can cause illness, may
grow in the media boxes, the mist eliminator, and the tank and may affect the air passing
through the MH duct unit. Maintenance must be performed as specified.
Caution: Servicing
 Poorly maintained humidifiers / coolers can endanger health of building occupants. If
the MH is not properly maintained microbials may grow in it. If carried by air passing
through the humidifier the germs can cause illness.

manual. Humidification boxes and mist eliminator media must be replaced after their
service life has elapsed.
