Accordion filter (fine mesh): Large and small sizes (attached to the inside of the filter unit)
NOTE:
• Replace all four lters at the same time.
• Before replacing the lters, wipe o dust and dirt from the projector cabinet.
• The projector is precision equipment. Keep out dust and dirt during lter replacement.
• Do not wash the lters with soap and water. Soap and water will damage the lter membrane.
