Preventative Maintenance
Air Handling Filter
Dust and Pollen Filter
Check and replace dirty dust and pollen filter once every twelve months, or
earlier if operating in highly dusty environments.
Other factors can also affect cooling. The air handler located under the
bunk, houses the air filter for the air conditioning system. The air filter should
be checked and cleaned periodically. You should also refrain from storing
items under the bunk near the air handler and electrical components.
Kenworth
Fuel Filter
The fuel filter should be inspected every month during the heating season.
Check the filter for debris, sediment or water. Replace if any is found.
Replace the filter annually, preferrably before the start of the heating season.

used.
