28 Owner’s Manual for Flameless Air Heater
Maintenance
Maintenance Schedule
Periodic inspection, service, and maintenance of this unit
is critical to ensure reliable operation. The following is the
manufacturer’s recommended maintenance schedule.
The maintenance items will need to be performed more
frequently if the heater is used in severe applications
(such as very high or very low ambient conditions or
extremely dirty/dusty environments). Use the heater hour
meter or calendar time, whichever occurs first, from the
previous maintenance interval to determine the next
required maintenance interval. Note that some checks
are based on hours of operation. Follow all applicable safety alerts found in this manual or
engine service manual before performing any
maintenance checks or service.
This maintenance schedule reflects the minimum tasks
that need to be accomplished to verify the heater remains
operational. Some of the tasks can be performed by an
authorized operator and others must be performed by an
IASD.
NOTE: An authorized operator is one who has been
trained by an IASD in proper operation and inspection of
this unit.
