Please note, when replacing filters on your Greenwood heat recovery unit it is always necessary to also reset the filter change timer on the unit otherwise the service light will not go out.

These units work on a calendar timer basis and simply changing the filters will still present the same issue as the heat recovery unit has to be told by the user when the filters have been changed.

For instructions on how to reset the filter calendar or replace the filters on your unit please download the HR155WM Home Owners guide under the "technical" tab of this page and reefer to page 8 of the manual.
