Before using
Funconing and basic sengs
The grinder models K30 TWIN 2.0 and K30 TWIN 2.0 HYBRID each have two
grinders that can be controlled separately (le and right).
The shot sizes, i.e. the volume of grounds per withdrawal, are dened by the
grinding me.
The user can specify up to six dierent recipes (grinding mes) for each of
the grinders (recipe mode) and also has the possibility of controlling the
grinding me manually (manual grinding).
The grinding process is started automacally when the portalter/grounds
container is inserted and either stops automacally aer the dened grind-
ing me has elapsed (grinding according to recipe) or when the portalter/
grounds container is removed (manual grinding).
K30 TWIN 2.0:
Model K30 TWIN 2.0 has two portalter spaces, i.e. the grounds of both
grinders fall directly into the inserted portalter.
You can modify the K30 TWIN 2.0 grinder using a hybrid kit, and
as such, set up a container space instead of a portalter space
(analogous to model K30 TWIN 2.0 HYBRID).
To do this, contact a cered service technician who can install
the hybrid kit and unlock the soware menu.
K30 TWIN 2.0 HYBRID:
The K30 TWIN 2.0 HYBRID model has a portalter space and a container
space, i.e. the grounds of one grinder fall directly into the inserted portalter
and the grounds of the other grinder fall into the inserted grounds container
(e.g. for lter coee).

Seng up the grinder and inserng the bean container
INFORMATION!
Risk of damage!
Improper use can lead to damage of the bean container.
– Make sure during installaon to posion the bean container
in such a way that the locking screw for the bean container
reaches into the appropriate recess of the bean container when
screwing in. If you do not posion the bean container correctly,
you may damage the bean container when screwing in the
locking screw.

17
K30 TWIN 2.0 (HYBRID) | EN
For grinders designed for mains voltage ranges of 200–230 V or
220–240 V, the locking screw for the bean container is a hexagon
socket screw. Use the 2 mm Allen key supplied with this model to
x the bean container.
For grinders designed for a mains voltage range of 100–127 V, the
locking screw for the bean container is a sloed screw. Use a slot
screwdriver to x the bean container (not included in delivery).
1. Place the grinder on a level and stable surface that does not vibrate to
prevent it from falling o.
2. Make sure that the rubber ring (23) has been properly posioned in the
bean container intake (2) and is lying at (see Fig. G).
3. Keep pressing the grinding degree release (5) forward (in the direcon of
the display (14)) and, at the same me, use the grinding degree adjustor (4)
to set the grinding degree to the nest level (scale value “0”) (see Fig. F).
Turn the grinding degree adjustor in such a way that the groove in the
grinding degree adjustor indicates “0” on the grinding degree scale (3).
The locking mechanism can become damaged if you turn the
grinding degree adjustor with force without holding down the
grinding degree release at the same me.
4. Place the bean container (1) onto the bean container intake (see Fig. G).
In doing so, make sure that the pins in the bean container intake catch
the corresponding grooves on the bean container and the recess for the
locking screw on the bean container aligns in the direcon of the locking
screw on the bean container intake.
5. Keep pressing down lightly on the bean container and turn the bean con-
tainer clockwise so that it clicks into the bean container intake.
6. Use a slot screwdriver or the 2 mm Allen key supplied to screw the lock-
ing screw (24) for the bean container clockwise unl nger-ght. Make
sure not to screw the locking screw too ghtly. The locking screw should
be level with the grinding degree adjustor.
7. Repeat steps 2–6 to insert the second bean container into the remaining
(free) bean container intake.
8. Seal the bean container by sliding in both sliding valves (15).
If you do not need both sliding valves, you can clamp them to the
boom of the drip tray (see Fig. E).

18
DOUBLE ESPRESSO GRINDER
9. Place the drip tray (13) into the corresponding opening under the outlet
(6) so that the magnets underneath the drip tray sit in the appropriate
intakes.
Connecng the potenal equalizer
The connecon for potenal equalizaon (19) is located on the back of the
grinder (see Fig. C). The electrical connecon and tesng of electronic func-
onality must be carried out by an electrician.
1. Loosen and remove the lock nut (see Fig. D).
2. Remove the lock ring and the at washer.
3. Connect the potenal equalizaon conductor (22) to the potenal
equalizer.
The potential equalization conductor is not included with
delivery.
Use a copper potenal equalizaon conductor with a minimum
cross-secon of 10 mm2.
If you have quesons about this, contact an authorized service
partner or electrician.
4. Secure the potenal equalizaon conductor by reaaching the nut, at
washer and lock ring.
5. Make sure that the grinder is switched o (On/O switch (21) to “0”) and
connect the grinder to the power supply by inserng the power plug (20)
into a properly installed safety socket.

DOUBLE ESPRESSO GRINDER
Operaon
INFORMATION!
Danger of overheang!
Exceeding the maximum permissible operang cycle can cause the
grinder to overheat.
– Do not exceed the maximum operang cycle
(see chapter “Technical data”).
– Observe the recommended pause when the maximum permis-
sible operang cycle is reached (see chapter “Technical data”).
• The grinder has two fuses that act as an overcurrent
protecon device. If this overcurrent protecon device is
triggered because of electric overload, the grinder’s circuit is
interrupted.
• To be able to operate the grinder once again aer triggering
the overcurrent protecon device, switch the On/O switch
(21) to “0” (o) and contact an authorized service partner
(see chapter “Service”).
• The grinder also has a motor protector, which switches o the
grinder when the motor becomes too hot. As soon as the
motor has cooled down, the grinder can be put into operaon
again (see chapter: “Troubleshoong”).
Adding coee beans
1. Remove the lid from the bean container (1).
2. Pour whole roasted coee beans into the bean container from above.
• The maximum lling quanty should be approx. 1 cm below
the edge of the bean container.
• The minimum lling quanty should not fall below 2 cm in
order to ensure that there are no dosing uctuaons.
3. Place the lid back onto the bean container.
4. If necessary, open the bean container by pulling out the sliding valve (15)
(see Fig. G).
