Description of the electrical parts

This unit is equipped with a mains socket with fuses incor-

porated. The main switch ON/OFF is placed on the back

side of the unit.

The mains voltage (high voltage of 110, 220 or 240 V AC)

is converted into 24V AC (low voltage), by an internal trans-

former, to supply all the electrical components of the unit.

Description of the hydraulic parts

AirFlow

®

S1 is equipped with a water lter at the entrance

of the water supply. Water circuit is made by blue hoses.

On the AirFlow

®

unit, the water passes through a water

lter then though a water regulator allowing the regulation

of the ow, and goes into the pneumatic module driven by

the electrovalve, the heater and the polisher handpiece via

the handpiece cord.

Description of the pneumatic parts

AirFlow

S1 unit is driven by a pneumatic footswitch. Internal air

circuit is made by yellow hoses.

It is equipped with an air lter at the entrance of the air supply.

The air passes through a regulator allowing the regulation of the

ow, and goes into the a set of two air lters before its entrance

into the powder bowl.

The pneumatic module for polisher, the pinch valve and the water

circuit are driven by the air circuit.

Description of the powder parts

The powder circuit is used on the AirFlow

system. The

powder circuit is made by a transparent hose.

The powder comes from the powder bowl and passes

through the pinch valve allowing the stop of the ow, and

goes into the polisher handpiece via the handpiece cord.

Assembly of the knob

The regulators and taps sent for After Sales Support

are ADJUSTED and TESTED to function correctly.

Don’t modify the adjustment before assembly.

Preparation of the regulator holder

Cut the three external pins coming from the moulding.

Lay down a lm of silicone paste on the contact surface

between the knob and the holder.

Assembly instructions

Put the knob (68) and the elastic washer (69) into the knob

holder of the regulator in such a way that the stop of the

knob is as close as possible to the stop of the knob holder

(on the left). Do not turn the axis of the regulator. The knob

should be able to turn in a clockwise direction (thus open-

ing the regulator).

Turn the knob anticlockwise (0

o

-15

o

) to join the 2 stops. The

regulator is now at minimum position.

Put the assembly into the upper casing of the unit (from

inside), the spot of the knob should be opposite to the spot

on the casing .
