The air intake fi lter (Alpha P/N 561-216-10) is located on the rear door of the enclosure.
Failure to keep the fi lter clean, or using improperly installed fi lters, may cause system failure due
to dirt buildup or lack of cooling air. Equipment failures caused by fi lter blockage, incorrect fi lter
substitution, or dirt ingress due to clogged or improperly installed fi lters are not covered under
warranty.
CAUTION!
Filter Removal, Replacement, and Cleaning
1. Unlock and remove the rear door.
2. Pull the four captive fasteners out, Fig. 7-1.
3. Tilt the fi lter frame away from the door and remove the fi lter, Fig. 7-2.
4. Clean the fi lter using a vacuum or compressed air (if available) to remove loose dust and
dirt. Then use a soap and water solution to remove any trapped dirt. Use compressed
