5 The green LED lights up.
6 The pump will begin to fill the boiler.
7 As soon as the boiler is filled, the pump stops. As soon as the fresh water drops down to a certain
level in the water tank, the machine switches off and the light of the green LED starts blinking. Once
the tank has been refilled, the machine will automatically start heating up.
8 As a large amount of water is required when first filling the boiler, the water tank will need to be
refilled with fresh water.
9 Wait until the boiler pressure (indicated on the upper part of the gauge) shows 1.0-1.5 bar.
10 A manual "boiler ventilation" is not necessary because the PRO 400 is equipped with a professional
depression valve that ventilates the boiler during the heating phase.
11 Move the brew group lever into the upper position and dispense approx. 250 ml of water. The heat
exchanger will be filled with water and the circulation of the water in the thermosyphon system begins.
12 Move the brew group lever into the lower position. Refill the water tank if necessary.
13 The machine is now ready for use. Place the cups on the cup heater tray to preheat them and enjoy
your coffee.
Before making the first coffee, please rinse the machine by extracting about 2-3 water tanks
worth from the brew group and the hot water wand. See also chapter 6.9.1 Dispensing of hot
water
The PRO 400 has a fuse to prevent the machine from overfilling.
It is possible that the machine does not heat up when using it for the first time or when
dispensing large quantities of water through the hot water valve. In this case please
switch the machine off and on again.
Please note that the portafilter, drip tray and water tank are not dishwasher safe.

USE OF THE MACHINE

6.1 Preparation of the machine

The switched off machine is to be placed into operation as follows:
1 Fill the water tank, if necessary.
2 Turn the machine on (power switch in position "ON").
3 Wait until the boiler pressure (indicated on the upper part of the gauge) shows 1.0-1.5 bar.
4 Depending on the ambient temperature, the heat-up phase is approx. 15 minutes.
5 The machine is now ready for use.
6 Insert the portafilter and move the brew group lever into the upper position. Release some hot water
to heat up the portafilter.
It is recommended to leave the portafilter in the brew group, keeping it warm for optimum
temperature for coffee extraction.

6.2 Manual adjustment of the brewing pressure

You can individually adjust the brewing pressure by turning the adjusting screw, between approx. 8.5 and
12 bar.
To adjust the brewing pressure, proceed as follows:
1 Open the cup warmer tray.
2 Place the portafilter with the blind filter into the brew group.
3 Operate the brew group lever and read the brewing pressure on the lower section of the gauge.
4 Choose the desired brewing pressure by turning the adjusting screw with a flat screwdriver or similar.
You can reduce the brewing pressure by turning the screw anti-clockwise and increase it by turning it
clockwise.
5 Check the pump pressure (on the lower part of the gauge) to see the adjusted brewing pressure.
6 Put the brew group lever back into the lower position. Remove the portafilter from the brew group,
then remove the blind filter and insert a coffee filter again.
7 The machine is ready for use again.
