ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 18/07/2016 | K04673
Please, check that the three-phase factory installation is correct.
Make sure our socket is EN 60529 and has 3F+N+T and the distribution of the
connection should be as in Figure 2.
Obtain 380V 50Hz or 220V 60 Hz between phases ( ) and 230V 50Hz or 110V
60Hz between Phase and Neutral ( - ).
In order for a correct grind, the burrs have to turn in a counter-clockwise direction.
When plugging in a three-phase grinder for the rst time, check that the burrs turn in
the right direction by opening the cover and looking into the hopper.
If the direction of the burrs is not correct, unplug the grinder and, with the help of a
at-head screwdriver, turn the phase reversal device 180º as soon shown in Figure 1.
When you plug the grinder in again, it should turn counter-clockwise.
NOTE: The coffee grinder should be used in areas with a room temperature below
30/35ºC ( 86/95ºF ) and should not be installed in places (SUCH AS INDUSTRIAL
KITCHENS) where cleaning with water jets is used.
8. OPERATION
8.1. Main switch
The main swith ( ) has 2 positions of use, ON–OFF

the hopper clicks into place on the upper body ( ) (Fig. 4 & 5).
Turn the upper body around and x the hopper to the grinder body with the safety
screw that comes along with the grinder (Fig. 3).
NOTE: The manufacturer cannot accept responsibility for any damage casued by
improper use of the machine.
8.3. Use
Open the hopper lid ( ), ll the hopper ( ) with coffee and close the lid. Once the
coffee is inside the hopper, it can not be removed.
Press the bag support handle ( ) and put the empty bag around the coffee discharge
tube ( ), then release the handle so the bag remains xed in place.

ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 18/07/2016 | K04673
Push the start button ( ) on the left of the front setting dial ( ) and the grinding
process will start (the selected grinding choice icon will ash). Once you have ground
the desired quantity of coffee, push the grinding stop button ( ) on the right of the
front setting dial ( ).
Remove the bag, holding it with one hand and with the other, push the bag support
handle ( ) down to release it.
Push the handle two or three more times against the outlet to remove so that any
remaining traces of coffee which may have stuck to the discharge tube ( ).
NOTE: The amount of coffee ground will depend on the chosen grinding point.

9. VIBRATING PLATE
9.1. Vibrating plate
The grinder comes with an extension to distance the bag shaker from the machine,
allowing the possibility to use bigger bags (>0.55 lb for R80 & R100 and >1.1 lb for
R120 & R140) and therefore grinder larger amounts coffee.
To put the extension in place, remove the screw ( ) on the lower part of the bag
shaker as indicated in Fig. 7 and put the adapter in place. Reconnect the bag shaker
using the same screw.

10. CLEANING
10.1. General warnings
To guarantee the correct operation of the machine as well as the quality of the
ground coffee, periodically clean the parts that come into contact with the coffee (at
least once a week).
Before performing any type of maintenance work, the following indications must be
taken into consideration:
• Always turn off the machine using the general switch ( ).
• Disconnect the machine from the power supply.
• Do not submerge the grinder in water or use power washing devises.
• The appliance is not to be cleaned with a water jet.
10.2. Bean hopper cleaning
It is recommended that the grind chamber be cleaned monthly with a cleaner as
recommended by Compak. This process will eliminate smelly residues from the
coffee remains, which can negatively affect the quality of the brewed coffee.
The steps to follow are:
• Grind out the remaining coffee in the grind chamber.
• Pour 60 gr of grinder cleaning product into the bean hopper ( ).
• Grind the cleaning product at a medium course grind setting until it is passed
through the system and nothing remains in the grind chamber.
• Clean the hopper ( ) and rell with coffee beans.
• Discard the rst 2-3 doses of coffee to assure that the residual cleaning product
is removed from the grind chamber and set the grind regulator to the desired
setting ( ).
Following these steps will ensure that the grinder is clean and ready for use.
We do not recommend the taking apart of the grind assembly unless changing burrs,
or removing a blockage/obstruction in the grind chamber. Removal of the grind
assembly should be performed by a qualied service technician.

13
10.3. Cleaning the coffee discharge tube
To clean the tube ( ) use the brush that comes with the grinder and insert it several
times to remove any coffee remains.
ALERT: It is recommended to follow the cleaning instruction described in this point
at least once a month.
10.4. Cleaning the outside of the grinder
To clean the outside, use a dry brush and then a cloth that has been slightly
dampened in soapy water.
NOTE: FAILURE to perform these cleaning operations will affect the taste and
aroma of the coffee.

ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 18/07/2016 | K04673
11. MAINTENANCE
11.1. General warning
Before performing any type of maintenance you should:
• Always turn OFF the main power switch to the off position ( ).
• If the grinder is jammed, unplug it from the power source and contact an
authorized service technician.
Not following these warnings can compromise the safety of the grinder as well as
the user.
11.2. General maintenance of the grind chamber
To guarantee the efciency and correct operation of the grinder, it is essential to
follow manufacturer instructions and ensure that all maintenance work is carried
out by qualied staff.
Dull burrs will result in; a lower quality grind, greater heat generation in the coffee
and grinder, increased electrical consumption, and nally it puts additional stress on
the grinder motor.
NOTE: Based on extensive experience and a medium-hard coffee blend, we
recommend replacing the burrs according to the following table:
Kg / lb of ground coffee
R8 800 Kg / 1322.77 lb
R80 6.800 Kg / 14,991.43 lb
R100 10.000 Kg / 22,046.23 lb
R120 12.000 Kg / 26,455.47 lb
R140 15.000 Kg / 33,069.34 lb

11.3. Grinding group maintenance
Not following the recommended burr life guidelines can compromise the safety of
the grinder.
These operations should be done by a qualied service tecnician.
• To effect grinding group maintenance work, the following instructions should be
followed:
• Turn the front setting dial ( ) all the way to the left.
• Turn the machine off, using the ON-OFF switch ( ).
• Disconnect the cable from the power supply.
• Remove hopper ( ) from upper body ( ) according to section 7.
• Dismantle upper body ( ), by unscrewing the two rear screws. Remove the four
setting screws ( ) of the upper burr holder from the grinding cup (Allen wrench
4), according to Fig. 8.
• Replace the burrs by unscrewing them from their upper and lower supports.
During this operation, it is recommended to block the rotation of the lower burrs
with a at-head screwdriver.
• Clean the coffee remains from burr holders.
• Take out the used burrs and put in the new ones.
• Assemble to setting screws ( ) of the upper burr holder to the grinding cup.

ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 18/07/2016 | K04673
11.4. Reset the burrs to the 0 / Calibration
Position 0 is the point in which the burrs no longer touch.
Following these instructions allows the user to make small adjustments to adapt the
desired particle size for each of the types of coffee referenced on the front control
knob ( ).
• Turn the front dial ( ) clockwise until the burrs are as close as possible without
touching.
• Loosen, with the help of the key wrench that comes with the grinder, the screw
( ), until the chain is released.
• Turn the front dial ( ) clockwise as far as possible.
