11.3.2 Replacement of Air Filter
The air filters need regular inspection and replacement. The inspection and replacement intervals are related to the
environmental conditions of the UPS. Under normal environmental conditions, the air filters should be cleaned or replaced
once every two months and need more frequent cleaning and replacement in dusty or other harsh environments. Frequent
inspection or replacement should also be made in new buildings.
The UPS provides air filters on the back of the front door of the cabinet, and the user can replace the air filter during the
UPS operation.
Each air filter is fixed by a fixing bar on both sides. Refer to Table 11.1 on the previous page, the following is the air filter
replacement procedures:
1.
Open the front door of the UPS to reveal the air filter on the back of the front door.
2.
Remove a fixing bar on one side and loosen the fixing screws of the fixing bar on the other side, with no need to
remove this fixing bar.
3.
Remove the air filter to be replaced and insert a clean one.
4. Re-install the removed fixing bar in the original place and tighten the fixing screws.
5.
Tighten the fixing screws of the fixing bar on the other side.
