• HVAC performance issues tied to an aging filter drier

Installation Notes

Confirm pad-mount fitment, inlet and outlet orientation, and bracket/stud mounting before installation. Replace the sealing washers during service and evacuate the system properly after installation to remove air and moisture. Because the desiccant is not replaceable, install the unit as a complete replacement rather than attempting to service the internal media.
