4.6 Brewing Process
Reference Drawings
Step 1 Ascent of the piston
The ground coffee and the water are dispensed into the
brew chamber during the ascension of the piston. This
compresses the air in the cylinder and forces it through the
coffee mixture in the brew chamber thereby agitating the
brewing coffee.
Step 2 Pauses
Once the piston has reached its top dead point, it will pause to
allow the coffee to brew to the appropriate strength. There will
be one shot of water before the descent to rinse the chamber.
Step 3 Descent of the piston
The descent of the piston will create a vacuum thereby extracting
the coffee from the grounds through the lter paper and into the
cylinder. One last pause will be to allow all the coffee to drip from
the brew chamber.
Step 4 Product delivery
The piston follows its course heading to its low dead point.
Distribution of coffee through the spout begins once the piston is
below the coffee exit. Meanwhile, the brew chamber lifts to allow
the paper to advance thereby discarding the spent grounds into
the waste chute.

Control & Features
5.3 Automatic Safety Features
There are various safety mechanisims on this brewing equipment to prevent a machine malfunction
resulting in material damages.
Water Level Switch and Heater Safety Switch
The water level switch and the heater safety switch work together to ensure that the heating element is
deactivated if there is insufcient water in the tank. The water level switch is controlled by a oat and will
shut off the inlet valve when the tank is full. If the level in the tank gets too low, the heater safety switch
will be triggered and the heating element will be turned off.
Overow Switch
If the water were to boil, the tank water would go into the overow cup and all machine functions would
be turned off. This is a fatal error. This could also be triggered if the oat in the tank was defective or if the
machine was moved while the tank was full. The unit would appear Off.
Overow Drip Tray
This will be triggered if the drip tray is full or if something is leaking inside the unit. This will deactivate the
water inlet valve thereby preventing the element to heat. The unit would indicate “Drip tray full’.
Software Safety Features
At the time of the rst tank ll, the water inlet valve will close after 4.5 minutes of continuous demand. This
is the amount of time necessary to completly ll the tank. After the initial tank ll, the inlet valve will close
after 20 seconds of continuous demand. This safety mechanism is designed to prevent water from owing
continuously into the machine due to a mechanical malfunction. The unit will indicate “Low water level”
If the low water level switch is triggered but not the heater safety switch, the element will automatically be
shutoff. This is in the event of a mechanical failure of the heater safety switch.
