trimmed (pointed) hose end. After installation cut pointed end apart. Install cone as shown, pull
coupling nut hand-tight.

5.2. Cassette medium;

Medium-model cassettes exclusively have been designed for C8 multi-channel
pump heads.

When cassette is interlocked with multi-channel pump head exert some pull force on both ends of
the hose to prevent hose from looping.
To adjust roller contact pressure, turn setting knob until inboard wedge reads between 3 and 4 on
the scale; refer to Chapter 5.1.1 to optimize roller contact pressure.

Large-model cassettes exclusively have been designed for C8 multi-channel
pump heads.

ff); these cassettes however do not feature stoppers, they use hoses from the reel only (refer to
Chapter 15, reference table).
The large-model cassette features adjustable hose retainers on in- and outlet ends. These
retainers adjust hose clamping action for different sizes of hoses. To adjust setting knob (61) make
