6. Maintenance
6.1 High Efficiency Air Filter
The Quest Dry 70 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.
To replace the filter, remove the filter door from one of the sides of the Ultra-Aire 70H by pushing the snap
button in and gently pulling to door away from the body of the unit, then pulling up to disengage the door
flange from the slot, removing the door.
Remove the filter by gently pulling straight out of the unit. Insert new filter in the same manner, pushing it
gently straight into the unit.
Replace filter door by inserting the bottom tab into the slot, aligning the door and pushing it gently against
the unit until the snap button secures the door.
