35. Flask supports
The flask supports make flask (1) removal (even filled) an easy job for one person.
3. Uninstall flask: Open enclosure (2). Engage drive lock (3). Slide support pipes (4) to flask (1)
from both sides. Check for firm contact and lock support pipes in place by tightening
thumbscrews (5) CW. Unscrew large coupling ring (6, not shown) by turning CCW. Tilt flask
neck with large coupling ring (6) forward. Remove flask carefully (coupling ring to remain on
flask).
4. Install flask: Open enclosure (2). Engage drive lock (3). Move support pipes (4) (both sides) to
the respective flask size mark (center of thumbscrew = mark). Mark I = 10 l flask; mark II = 20 l
flask. Lock support pipes in place by tightening thumbscrews (5) CW. Put flask (1) , holding
large coupling ring (6), on support pipes carefully. Swing flask axis with coupling ring in-line with
axis of rotation, until flange is centered in drive head. Secure PTFE-adapter (not shown) with
PTFE-O-ring tight by CW turn. Double-check for firm seat. Return support pipes to initial
position (7). Release drive lock (3). Caution: Basic position of support pipes is monitored by the
electronic circuit; when leaving this position, all electric functions of the system will freeze.
This situation is reported by the Flask Support LED on the control panel.
