Hydraulic connections
The plumbing and the electric power cable lead out from the back of the dishwasher. Connect the water supply pipe to a tap
with threaded ¾" gas fitting.
Use only new pipes to connect to the water supply. Do NOT use old or worn ones.
The dynamic supply pressure must be between 200 and 400 kPa; if it is higher, install a pressure reducer. (version with built-in
water softener, between 300 and 400 kPa). If it is lower, install a pressure booster pump.
Install a main cock on the supply water inlet piping; this cock must be accessible after the appliance has been installed. Do not
install the cock behind the dishwasher.
The stated cycle time refers to hot supply water at 50°C.
If cold water is supplied, the timing could be longer in relation to the temperature of the inlet water.
For versions with built-in osmosis system, install the carbon or mesh filter supplied on the water supply cock. The water
hardness must be between 7 and 12°F and the maximum temperature 30°C.
The filters must be replaced at least twice a year.
Failed observance of these parameters will cause the internal osmotic membrane to deteriorate rapidly.
Make sure the water hardness is between 7 and 12°F, otherwise install a water softener to prevent damages caused by scale,
which are not covered by warranty.

Drainage:
Every dishwasher is supplied with its own drainage connection pipe, to be connected to a siphon-type drain in the floor. If
connected to a drain in the wall, a drain pump needs to be installed.
Attention: make sure the supply and drain pipes are not bent, choked or squashed after they have been
installed.
Electrical connection
The electrical connection of the dishwasher and any other supplementary appliances is to be done by authorized and qualified
personnel, in compliance with current standards; also observe the technical connection instructions.
The total installed power is written on the appliance's technical data plate. The protection system of the dishwasher lines must
not include other appliances.
The user shall have a qualified and specialized technician install a main on/off switch on the electrical line and a differential
switch compatible with the machine, in compliance with current standards.
These switches must be installed near the dishwasher, must be easy to reach after installation and must guarantee complete
disconnection of the electrical mains in the conditions of the overvoltage category III.
Attention!
The dishwasher is totally free from electricity, hence not live, exclusively when the main on/off switch is switched
ooff.
Connect the appliance to the utility equipotential system. The terminal with this symbol
-
at the back bottom part of the machine.
The earthing protection wire (PE) is yellow and green, the neutral wire (N) is blue and the phase wires (L1, L2, L3)
-
are black, grey and brown.
Attention: Make sure the phase wires are not inverted with the neutral wire, both on the five-pin plug of the power
