APC ACF002 ユーザーズマニュアル

Depending on your enclosure’s height and the heat output of 
installed equipment, you may choose to operate only one fan, 
thus reducing energy consumption. Smaller enclosures often 
require only one operating fan.

You may also choose to operate both fans during normal 
operation, and turn off one fan in the event of a loss of utility 
power. This will conserve run-time on the battery of the UPS.

Replace your air filter whenever other system air filters are 
scheduled to be replaced or at a minimum once a year. 

1. Turn off both fans on the fan assembly, and wait for the 

fans to stop.

2. Unplug the power cord(s) from back of Air Distribution 

Unit.

3. Open the front door of the enclosure and slide the fan 

assembly forward as far as it will go.

4. From the rear of the enclosure, remove the old filter and
