4.3 Electrical Installation

Prior to plugging in observe the following safety instructions:

Protect your device with separate pre-fuses (not 

included in the scope of delivery) according to 

the information provided under point 2 „Techni-

cal Data“

Make sure that the pre-fuse is not overloaded 

by other devices (e.g. fan heaters, deep freezers, 

etc)

Check whether the main voltage and frequency 

correspond to the information on the rating 

plate underneath the grinder.

Insert the plug into the corresponding grounded outlet. 

4.4 Adjustment of the port-a-fi lter rests

The grinder is designed so that all different port-a-fi lters from vari-

ous espresso machines fi t into the rest for hands-free grinding op-

eration. 

4.4.1 Keep the grinder switched off. Slightly loosen the allen screws 

(pos. 13)  with the included allen screw driver size 3mm and pull 

down the port-a-fi lter rest (pos. 12).

4.4.2 Push the port-a-fi lter of your espresso machine onto the start/

stop switch between the port-a-fi lter mounting (pos. 11) and the 

rest (pos 12). Now push up the port-a-fi lter rest until the port-a-

fi lter holds on its own. Now refasten the screws. 

4. Set-up and Initial Adjustments

You have received your grinder in operating condition. Now you only 

need to place it in a safe place and connect it to the main power 

socket. Proceed as follows: 

4.1 Place of Installation

Place the grinder on a level, vibration-free surface. 

Never operate the grinder in moist, or even 

worse, in wet surroundings!

4.2 Locking in the hoppers

Set the hopper into the bayonet socket. Grab the hopper with both 

hands and turn it carefully in clockwise direction, until the bayonet 

locks in.

Always loosen the grind adjustment brakes and 

turn both adjustments to fi ne (setting 0) when 

locking in the hoppers. Turning the grind adjust-

ment ring repeatedly without loosening the 

brake could damage the interlock.

Fasten the lock screw for the hopper (pos. 2) to prevent the hoppers 

from unauthorized removal.
