5 Putting into operation

43 Multivapor™ Operation Manual, Version E

5.5.2 Vacuum tubes

When establishing the vacuum tube (red rubber) connections proceed as follows:

• Use GL-14 tube clips.

• The tubes used must all have the same inner diameter (approximately 5 mm).

• Keep vacuum tubes as short as possible.

• When operating with the Vacuum Controller V-850/V-855 and the Vacuum Pump V-700/V-710

connect a Woulff bottle between the vacuum source and the Multivapor.

• When operating with a pump other than a V-700/V-710, connect a valve unit to the V-850/V-855 to

control the vacuum.

• Tubes do not need to be secured.

• Check the tubes from time to time and replace them if they become brittle.
