Note 1: The part code of the O-ring is the one assigned to NBR-70-1 which is standard material.
Note 2: When checking each part (No.30, 33, 50, 480, 491) If a special malfunction is not seen, it is
possible to use in the continuation.
Note 3: Mechanical seal assembly (No.100) should be replaced if any defect is found during inspection.
Actually, however, it is sometimes difficult to find out defects on the sliding surface only through visual
inspection. In such circumstances, MAYEKAWA recommends to replace it with a new one.
Also, if it is difficult to stop the compressor operation except for scheduled inspections, MAYEKAWA
recommends replacing No.100 in the same way.
