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:
Water temperature (T):
If the water hardness is more than 10 ⁰ f H (French degrees), a descaler 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:
DYNAMIC
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.

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 the following range.

5 ⁰C < Tª < 35 ⁰C / 41 ⁰F < Tª < 95 ⁰F
If using hot water, the water temperature must not exceed 60 ⁰C / 140 ⁰F.
If using hot water, the glass washer cold rinse will not be efficient.
All the machines should have a ¾" screw-on connection.
