The air intake lter (Alpha P/N 561-216-10) is located on the rear door of the enclosure.
Failure to keep the lter clean, or using improperly installed lters, may cause system failure due
to dirt buildup or lack of cooling air. Equipment failures caused by lter blockage, incorrect lter
substitution, or dirt ingress due to clogged or improperly installed lters are not covered under
warranty.
CAUTION!

2. Pull the four captive fasteners out, Fig. 7-1.
3. Tilt the lter frame away from the door and remove the lter, Fig. 7-2.
