Mount tubes: Multi-channel pump heads
Multi-channel pump heads require cassettes to mount tubes. You will nd the right sizes
of cassettes in our general catalogue or at the end of this manual.
Warning:
Risk of crushing!
While mounting and demounting cassettes you can crush your
ngers, if rotation starts accidentally.
Always switch device OFF at main switch before mounting cassettes.
Caution:
Possible damage of device
Multi-channel pump heads require a certain combination of cassettes
and tubes. Other combinations lead to premature wear or to
malfunctions.
Only use combinations of cassettes and tubes tting your Multi-
channel pump head as laid out in this manual (see chapter
„Technical data, Table tubes”).
All cassettes operate in both directions. However, we recommend to
mount cassettes alternating. This way the clamping can be adjusted
more easily.
Cassettes and tubes: „Cassette small”
„Cassette small” is suitable for multi-channel pump heads C 4 and
C 12 only!
Caution:
Possible damage of device
Stopper on tubes with small inner diameter of 0.8 and 1-7 prevent
tubes from moving. Operating tubes without stoppers will lead to
malfunction and exclusion from warranty!
