To Adjust The Brewer Chamber Tension - VKI Technologies Zuma Brewer Operation And Service Manual

Zuma Brewer - Operation & Service Guide

To adjust the brewer chamber tension:

1. Make sure the brew chamber is open (up).
2. Push down on the H-frame (1).
3. Lift the T-bar out of its recession on the H-frame and turn it so that it is out of the way (2).
4. Adjust the brew chamber tension.
TO INCREASE TENSION:
a) Add one shim into the recession and replace the T-bar.
b) Test the operation of the brewer.
c) If more tension is required, remove the shims that were added and perform one full clockwise
rotation on the T-bar. One rotation of the T-bar is equivalent to adding two shims.
d) Test the operation of the brewer.
e) If more tension is required, repeat the above steps until the tension is correct.
TO DECREASE TENSION:
a) Remove one shim into the recession and replace the T-bar.
b) Test the operation of the brewer.
c) If less tension is required, remove the shims that were added (above) and perform one full
counter-clockwise rotation on the T-bar. One rotation of the T-bar is equivalent to
removing two shims.
d) Test the operation of the brewer.
e) If less tension is required, repeat the above steps until the tension is correct.
NOTE: If more than two extra shims are required, remove the extra shims and rotate the T-bar
accordingly instead. There should never be more than two extra full shims in the recession and the
original shim that was in the brewer should never be removed.
