Clean the return air filters frequently and for the environment for which
they operate. The return air filters are inside the air intake vent covers located
on the motorhome ceiling. Never operate the air conditioner without the return
air filters in place. This may plug the evaporator core with dirt and substantial-
ly affect the performance of the air conditioner.
To Clean:
• Remove the vent cover and filter.
• Wash the filter and cover in warm soapy water. Do not use solvents.
• Rinse the filter and cover thoroughly with fresh water. Allow to dry.
• Reinstall the filter and cover.
The roof air conditioners operate from the comfort control only
under the following conditions:
