4.4 Manual adjustment of the brewing pressure

The brewing pressure of the machine can be adjusted manually, without opening the machine, through an
adjusting screw at the bottom of the machine. This adjustment must be carried out by expert specialists.

5. FIRST USE

Read the instruction manual carefully prior to operating the machine.
Prior to starting the machine, check if:
• the steam and hot water valves are closed.
• the machine is switched off. (Power switch in the vertical position.)
• the power cord is disconnected.
• the drip tray is inserted accurately.
• the machine is placed on a water-resistant surface.
Now you can start up your machine:
5.1 Machine in use with water tank (steam/ hot water boiler activated)
1. Please make sure that the valve at the bottom panel of the machine and the switch behind the drip
tray are in the correct position (see chapter 4.3, image 3 and 4).
2. Remove the cup warming tray. Take out the water tank and rinse it thoroughly.
3. Fill the water tank with fresh water deficient in lime, place it back into the water tank guides and
replace the cup warming tray.
4. Plug the machine into an electrical outlet and position the brew lever upwards.
5. Turn the machine on by placing the metal switch in the upper position. The green control lamp and the
PID display will come on and a pump noise will be heard. The coffee boiler and the steam/ hot water
boiler are now filled with water simultaneously.

Fill mode

On the PID-
position the brew lever upwards for at least 30 seconds at a time. The coffee boiler and the steam /
pump noise, the filling of the steam/ hot water boiler is still being completed.
6. If the pump stops and the PID display turns off while the boilers are filled, you have to refill fresh water
in the water tank. If there is enough water in the water tank again, the pump starts to operate again.
7. As soon as both boilers are filled with water, the pump will become quiet. Both boilers are now being
heated in succession whereby the coffee boiler has priority.
8. The PID display will show the current temperatures of both boilers alternately (see chapter 3.3). The
machine is ready for coffee preparation as soon as the PID display indicates the pre-set nominal
temperature of 93°C (199,4 °F factory setting). The machine is ready for steam/ hot water dispension
as soon as the PID display indicates the pre-set nominal temperature of 129°C (264,2 °F factory
setting) or the boiler pressure gauge indicates a value of about 1.0-1.5 bar.
9. Manual boiler venting is not necessary because the PRO 700 contains a professional anti-vacuum
valve, which automatically vents the boiler during the heat-up phase. This venting process is done by
way of the brew group, directly into the drip tray.
