SYSMEX SF-3000 - Adjusting the Vacuum; Main Unit Adjustment

ADJUSTMENT, Pneumatic Unit
Sysmex SF-3000 Operator's Manual -- Revised September 1995 9-5
3.2 Adjusting the Vacuum
The vacuum cannot be adjusted in the Pneumatic Unit. If the vacuum falls
below 400 mmHg, take the following steps.
(1) Pinch the tubing that runs from the Pneumatic Unit to the Main Unit. If the
vacuum increases to 400 mmHg or more, a leak exists in the Main Unit. Contact a
Sysmex service representative.
(2) Check the above tubing and Pneumatic Unit internal tubing. If any of them is
disconnected, firmly reconnect it.
NOTE: As instrument usage increases, the vacuum gradually decreases. In
such cases, the vacuum pump and/or compressor gaskets may need
to be repaired or replaced. Contact a Sysmex service representative.
