5.2 Prearrangement of water supply

FEEDING lINE
Bring the water feeding tube (of at least 3/8" diameter) up to the machine and install an on-off valve (prefer-
ably of 3/8" ball type) that allows a rapid opening and closing operation. The appliance should be connected
to the water mains using the tube supplied with it. Do not connect the appliance with used tubes.
DRAIN lINE
Provide an inspectable drainage pit on the floor connected with the sink drainage line, suitable for receiving
the machine gravity drainage tube.
The drain tube must be positioned so that the water flows out freely, without possibility for the pipe to clog
up during the operation.

5.3 Water softener (optional)

The water softener for the mains water can be manual or automatic, depending on customer's request.
Before connecting the water softener to the coffee machine, the resins contained in it should be
washed off as described in the user's manual supplied with the appliance.
Note:
The water softener is considered an essential device to guarantee a proper operation of the espresso coffee
machine. A water softening system should be provided in order to guarantee the efficiency, performance and
duration of the components in the machine.
