Ultra-Aire 65H Installer’s & Owner’s Manual
FOR HVAC INSTALLER AND HOMEOWNER
6. Maintenance
6.1 High Efficiency Air Filter
The Ultra-Aire 65H is equipped with a MERV 11 media filter. This filter should be checked every three months. Operating the
unit with a dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle off and on
unnecessarily on the defrost control.
DO NOT operate the unit without a filter or with a less effective filter. Operating the unit without a filter or with a less
effective filter may cause internal damage to the unit and invalidate the product warranty.
6.2 Optional Fresh Air Intake
Check and clean the screen on the outdoor fresh air intake port seasonally. The screen may become plugged during the seasons
when there are many particles in the outdoor air.
