In cases where several of the above conditions exist (or if only one condition exists but to an
extreme), maintenance may have to be performed more frequently! To establish the correct
maintenance time interval for your specific unit installation, perform the tasks specified on the
PMCS checklist each day for the first week of unit use. At the end of the week if you find that
few, if any, of the tasks had to be performed repeatedly, extend the maintenance interval to
once a month. Again, if you find very little change in the condition of your unit from week to
week, extend the maintenance interval to once every six months. A semi-annual maintenance
interval is the longest recommended period.
