Preventive Maintenance - Bunn NITRON2 NGM Installation & Operating Manual

In order to maintain proper operation and long service life, BUNN requires an annual PM if the NGM is placed
in an ideal environment as laid out in the Site Requirements. The PM should take place in conjunction with the
Nitron dispenser's PM schedule. If the NGM is placed in a less than ideal environment, more frequent PM's
may be required.
NOTICE: To ensure quality air delivery to dispenser, change internal filters annually.
Value of Preventive Maintenance:
• Reducing unexpected amount of equipment failures throughout a year.
