EASYVAC VACUUM REGULATOR MS003 February 2010
Maintenance operations
Unscrew the lid, complete with the regulating knob
and the membrane, remove from the vacuum
regulator body and check that the inside surfaces
have not been accidentally contaminated by the
aspired liquids. If this is the case, perform the
operations indicated in the chapter “Warning” on
page 2 before continuing with the subsequent
phases.
Thoroughly clean the entire surface of the
membrane, using a soft cotton cloth dampened
with ethyl alcohol diluted to 60% in water.
Thoroughly clean the entire internal surface of the
body of the vacuum regulator, using a soft cotton
cloth dampened with ethyl alcohol diluted to 60%
in water.
Reattach the lid, complete with the regulating knob
and the membrane, onto the body of the vacuum
regulator, tightening it manually for as long as
resistance between the two parts can be felt.
Perform the functional checks required and
indicated in the operating manual Mo_002 of the
EASYVAC device before use.
2.3.3
REPLACEMENT
OF
THE LID WITH MEMBRANE
In order to ensure correct functioning of the EASYVAC vacuum regulator, the lid (1), complete with the silicone
membrane as shown in the drawing specified in the Table of illustrations on page 4, should be periodically
replaced. This is due to deterioration of elasticity of the membrane, which could interfere with stable and safe
regulation of the suction value set on the device.
The replacement operations are the same as those described in paragraph 2.3.2 above.
