4.4.4 Installing the water fitting
1. Connect the supply hose to the external water supply.
2. Open the water valve until a steady water jet comes out
of the hose in order to both clean the water hose of dirt
and ventilate it.
3. Then close the water valve on the external water supply.
4. Connect the external water hose to the GEKA coupling
of the water fitting (11).
5. Close both the water drainage valve below the pressure
reducer (5) and below the main connection (12).
6. Connect the internal water hose to the GEKA coupling
on the mixing zone.
NOTE
To ensure sufficient water pressure regard-
less of the pressure of the supply line, the machine is
equipped with a pressure booster pump.
!
WARNING
Water jet.
Risk of injury and risk of property damage due to es-
caping water.
1. Interrupt the external water supply by closing the water
valve.
2. In order to release the pressure (approx. 2 bar), open
the water drainage valve on the water measuring sys-
tem under the pressure reducer.
3. Only remove the hose from the external water supply
when the pressure gauge shows “0” bar.
4. Do not point the water jet at other people or yourself.
4.4.5 Air fitting
1. Use the air connection (1) to supply a sprayer.
2. Check that the connections fit together before con-
necting the air hose. If necessary, replace them with
suitable connections.
3. The pressure switch (2) is pre-set at the factory and
switches the machine on and off.

4.4.6 Compressor
There is an “ON/OFF” switch on the compressor.
4. Set this switch to “ON” to operate the mixing pump.
5. Set this switch to “OFF” in case of faults or mainte-
nance work.
