Manual Adjustment Of The Brewing Pressure; First Use - Profitec Pro 700 User Manual

Bedienungsanleitung / User manual Pro700
Important
•Please make sure that only your authorized Profitec-dealer connects the machine to the water
supply and installs the pressure regulator.
•To avoid calcification of the machine a water-softener is recommended. Regarding a regular
prophylactic descaling of your machine, follow the instructions in chapter "7.3 Prophylactic
descaling" on page 29. For the descaling of machines in use with direct water connection,
please contact your specialised service dealer.
The residual water is disposed off periodically by emptying out the water drip tray. Alternatively, you can
hook the machine directly up to a water drainage. Please proceed as follows: Remove the sealing screw in
the drip tray and fasten the drainage container to the rim below the drip tray. Connect a suitable hose (not
included with delivery) to the drip tray and to an already installed drainage syphon.

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.

FIRST USE

5.1 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.
Now you can start up your machine:
Water tank machine or machine in use with water tank
1 Lift the cup warming tray.
2 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. Turn the machine on by
placing the metal switch in the upper position. The coffee boiler is now being heated and the green
control lamp will come on. In order to turn on the steam boiler as well, please make sure that the switch
located under the drip tray is in position '1'. The machine is now turned on. The pump is activated and is
filling the steam boiler with fresh water. Both boilers are being heated in succession.
5 As soon as water is released through the brew group, position the brew lever back downward. The
coffee boiler is now filled with water.
Since much water is used for the initial filling of the boilers, the water tank has to then be refilled with
water.
6 As soon as the steam boiler is filled with water, the pump will become quiet and the PID-display will
show the current temperature of both boilers (reg. item 3.3). When the fresh water in the water tank
drops to a certain level, the machine shuts down and the PID-display turns off. You now have to refill
fresh water. The machine automatically heats up again.
7 Please wait until the boiler pressure gauge indicates a value of about 1.0 – 1.25 bars.
8 Manual boiler venting is not necessary because the Pro700 contains a professional Anti-Vacuum valve,
which automatically vents the boiler during the heat-up phase. This venting procedure is done by way of
the brew group, directly into the drip tray. Caution, steam forms!
9 The machine is now operational. In order to always have pre-heated cups, place them on the cup
warming tray and start enjoying your coffee.
Before preparing the first coffee, please clean the machine by extracting about 2L of hot
water from the brew group and the hot water wand.
