Replace Air Filter
A dirty air filter reduces the air volume and the system capacity. This problem can be avoided by periodically and
regularly cleaning or replacing filters. The frequency at which filters must be checked depends on the amount of
dust in the environment. If during inspection, the filters are frequently very dirty, the frequency of checks and
maintenance should be increased.
Clean the Preliminary Air Filter
The preliminary air filter can become clogged with dust and leaves or other debris after a period of use, and should
be cleaned with water or blown air.
