4.3.2 Voltage Configuration of the machine
The voltage configuration of the machine is stipulated on the nameplate (230V 1N~50Hz/60Hz). This
configuration cannot be changed; therefore, it is essential that the mains voltage of the premises
where the machine is to be installed is confirmed prior to purchase. Fig. 6
4.4 Hydraulic connection
The new hoses supplied with the appliance should be used (do not reuse old hoses).
Before connecting the machine to the water supply, the water quality should be tested.
Recommended water quality:
If the water hardness is more than 10 ⁰fH (French degrees), a water softener must be installed. In
addition to water quality, the pressure of the mains water supply must be considered. This is important
to ensure the machine operates correctly.
Required water pressure:
If the water pressure is higher than the recommended pressure, a pressure regulator must be
mounted at the output Fig. 2. If the mains water pressure is lower than the recommended pressure,
a pressure pump should be mounted at the mains water supply Fig. 3. It is not necessary to install a
pressure pump in the BT models.

The following requirements are necessary for the correct hydraulic installation of the machine.
The hydraulic circuit must be fitted with a valve to shut-off the water supply.
Check that the mains pressure is within the range indicated above.
To optimise the working of the machine, the manufacturer recommends that the water temperature at
the machine intake is within +5°C and 60°C.
If using hot water, the water temperature must not exceed 60 ⁰C / 140 ⁰F.
All the machines should have a ¾” screw-on connection.
4.5 Drainage connection
5 For Australia, watermark certified inlet hose and backflow prevention device. Must be installed in
accordance with AS/NZS3500.1 (water service supply) including installation of the supplied backflow
prevention device.
The water draining from the machine must flow freely and therefore the drainage pipe should be
lower than the drainage outlet Fig. 4. If the drainage pipe is not lower, a drainage pump will be
required. This must not be mounted at a height of more than 680 mm Fig. 5. In this case, the pump
may be requested at the time of purchase or subsequently. Drain pipes of 31mm in diameter must be
installed in accordance with AS/ NZ3500.2 (drainage) by means of coupled connection to a DN40 or
larger pipe
