28ENGLIShWarning !!When the machine is new the filter-holder sump may not bealigned (perpendicular to the machine itself) as shown in thefigure at the side, however this does not effect the efficientfunction of the same.After a short period of use the sump will gradually settle intoa correct position.A = Position of closed filter-holder with new machine.B = Position of closed filter holder with machine after a short periodof use.6.2 PRESSURE SWITCH ADJUSTMENTThe pressure switch shown in the figure acts to keep the boilerpressure constant by engaging or de-activating the electrical heatingresistance.This pressure switch is already calibrated to 1.1-1.3 bar during theinitial machine testing stage, but should a different working pressurebe required, it is possible to vary the operational field of the pressureswitch using the regulation screw (U); pressure reduction results ina reduction in temperature, whilst increasing the pressure will alsoincrease the water temperature.The regulation direction is shown in the figure and on the pressureswitch itself.The pressure varies by 0.1 atm for every complete screw turn,Warning: Disconnect the electricity supply before underta-king this operation.6.3 PUMP PRESSURE CALIBRATIONInsert the filter holder into the unit filled with regularly ground, dosedand pressed coffee.Switch on the unit switch or the unit control keyboard (15) and readthe pressure on the pump pressure gauge (6).NB: The correct pressure is of 8-9 atm.Should the pressure indicated on the pressure gauge be incorrect,turn it clockwise to increase the pump pressure and anti-clockwise toreduce the pressure.Once adjustment is complete check pump calibration by deliveringone or more coffees.Z= Pump pressure adjustment screw.6.4 FILTERS FOR COFFEE MACHINEDepending on the quantity of coffee ground, the appropriate filter mustbe as shown below to avoid that, once the coffee has dripped out, theleftover powder remains attached to the nozzle.UFig.6.03ABFig.6.05ZFig.6.04NF08/002/B1 coffee cup of 5,5 gr. ÷ 6,5 gr.pod for 1 coffeebarley pod for 1 doseNF08/004/B1 coffee cup of 6 gr. ÷ 7 gr.NF08/005/B2 coffee cups of 12 gr. ÷ 14 gr.NF08/009/BDouble pod for 2 coffeesThe filter may be recognisedby the letter “C” printedinside20 mm24,5 mm24,5 mm21 mmFig.6.06Note: Options include shower head gaskets that are thinner (8.1 mm,part no.
