12.2 ANNUAL AIR HEATER INSPECTION

To reduce possible failures to a minimum and to
keep the air heater operating at peak efficiency,
and therefore providing the best output and
ensuring the lowest operating costs, it is
recommended to perform a general inspection of
the air heater at least once a year. More frequent
servicing may be required depending on the
environmental conditions where the air heater is
installed. Regular inspections area necessary,
especially in dirty areas, to assess the servicing
frequency.
