Reminder
Step 1: Turn off HVAC
The AC/heat blower must be turned off before installing the filter
Step 2: Install filter
Wall unit:
Insert the filter into the wall unit in the direction of the arrow as shown in the figure.
Central unit:
Please determine the wind direction of the AC/heat blower first, and then insert the filter with its arrows matching the wind direction.
How to judge wind direction:
Place a paper towel in the central unit to determine wind direction. Install the filter with the arrow facing the direction in which the paper towel blows.
Note: Please make sure the arrow matches the wind direction. Installation in the opposite direction will result in the filter being crushed by the wind resistance, affecting the life of the filter.
