Operation
Adjustment of the Cup Dispenser
The dispensing height must be adjusted so that over the entire lift the uppermost item of crockery is con-
stantly moved upwards to a uniform dispensing height between 1.6'' (4 cm) and 2.4'' (6 cm) above the upper
rim of the housing.
Step 1 - Checking the spring adjustment
Load a stack of 15 to 20 items on to the stacking platform to test the dispensing height.
Wait for a reaction.
If the dispensing height of the crockery stack is about 1.97'' (5 cm) above the upper edge of the appliance,
the spring system is adjusted correctly.
If the crockery stack drops down only a little or not at all, the dispensing height must be altered by adjusting
the springs.
Step 2 - Altering the spring adjustment
The dispensing height is adjusted by hooking or unhooking tension springs on two attachment bars. The
springs are arranged in groups of 5, where 1 is a base spring (2) and 4 are adjustable springs (1) with lower
tension.
Figure 7
If the dispensing height is too high, adjustable springs must be unhooked.
If the dispensing height is too low, adjustable springs must be added.
Procedure for setting the springs:
Take the inserted crockery items out of the cup dispenser (if available).
Hook or unhook adjustable springs uniformly in all groups of springs.
Preferably unhook the adjustable springs. Always leave the base springs inserted, if possible. Always
unhook the springs on the lower attachment bar.
Both steps must be repeated as often as possible, until the dispensing height is in the range from 1.57'' (4
cm) to 2.36'' (6 cm). So long as the same kind of crockery is always used, the dispensing height only needs
to be set once.

Attachment bar with tension springs
Arrangement of the springs
A symmetrical arrangement of springs between the attachment bars is neces-
sary for guiding the stacking platform uniformly and without friction.
A slightly asymmetrical arrangement of springs within an attachment bar does
not pose any problem.
Spring system
Since all the cup dispensers are designed for a maximum crockery load, the
available spring system of the appliances is entirely sufficient for all usual
crockery items.
Owing to the base springs with higher tension, the unheated cup dispensers
are also unsuitable for plastic items.
