3 PNEUMATICAL ADJUSTMENTS
3.1 Adjusting internal water & air pressures
The filter/regulators control the internal water and air pressures. There are two ways to moni-
tor the pressures while adjusting the regulators: manually with a manometer (pressure gauge)
or using the unit’s own pressure sensors. The manometer is connected to the head of the
syringe handpiece and the pressures are adjusted similarly as explained for adjusting the
pressures using the unit’s own pressure sensors.
Air pressure
a) Enter service mode 38. Press the A-key to enter the air pressure mode. The unit
automatically closes down the main water valve and releases the internal water pressure via
the flush valve into the drain. The internal air pressure is shown on the display. The pressure
is shown in bars (1bar = 100kPa = 14.5psi).
b) Lift the cap of the air filter/regulator upwards and adjust the internal air pressure by turning the
regulator cap. Balance the pressure from the syringe air valve after every adjustment. The
factory preset value for the internal air pressure is 5.5 bar.
c) Lock the filter/regulator to the adjusted position by pushing down the regulator cap.
Water pressure
a) Enter service mode 38. Press the B-key to enter the water pressure mode. The unit
automatically closes down the main air valve and releases the internal air pressure via the
instrument multiplexer. The internal water pressure is shown on the display. The pressure is
shown in bars (1bar = 100kPa = 14.5psi).
b) Lift the cap of the water filter/regulator upwards and adjust the internal water pressure by
turning the regulator cap. Balance the pressure from the syringe water valve after every
adjustment. The factory preset value for the internal water pressure is 2.8 bar.
c) Lock the filter/regulator to the adjusted position by pushing down the regulator cap.
