Chapter 6 Maintenance
6.4 Preventative Maintenance
The only required preventative mai
ntenance is for the HPA compartment air intake filters
and the air-to-air heat exchanger/heater exterior coils.
As a general rule, it is recommended that the air filters and exterior coils be cleaned every 6
months under normal conditions, or every 3 months in dusty environments. UBS would
recommend that the filters and exterior coils be inspected more frequently and cleaning
intervals be adjusted as deemed necessary by the operator.
