13.8 SERVICE SCHEDULE
INSPECTION INTERVALS
The service schedule covers service and inspection intervals for
the components of an air handling unit. The unit contains one or
more of these components. Delete components that are not
applicable from the service schedule.
Date and sign every service.
The length of the service interval is calculated on the basis of
approximately 2000 operating hours in a 12 month period for a
normal AHU installation.
In dirty environments, the maintenance of the unit has to take
place more often.
