DANGER OF POLLUTION

Fig. 3

The manufacturer cannot be held respon­sible for any damages incurred if the sys­tem is not grounded.
For electrical safety, this machine requires
a ground system. Contact a technically
certified electrician who must check that
the line electrical capacity is adequate for
the maximum capacity indicated on the
unit label.

Fig. 4

The qualified electrician must also check
that the section of the installation’s cables
is large enough for the absorbed power of
the appliance.
Never use adapters, multiple jacks or exten­sion cords. When such items prove absolute­ly necessary, call in a qualified electrician.

The machine is can be installed in staff
kitchen areas in shops, offices and other
working environments, farm houses by
clients in hotels, motels and other resi­dential type environments bed and break­fast type environments.

Before turning on the unit make certain

The machine must be installed according
to the applicable federal, state and local
standards (codes) in force with regard
to plumbing systems including backflow
prevention devices. For this reason, the
plumbing connections must be carried
out by a qualified technician.
The warranty expires if the characteristics
of the power supply do not correspond to
the nameplate data.

When installing the device, it is necessary
to use the parts and materials supplied with
the device itself. Should it be necessary to
use other parts, the installation engineer
needs to check their suitability for use in
contact with water for human consumption.
The installer must Make the hydraulic con­nections respecting the rules of hygiene
and water safety to environmental protec­tion in force in the place of installation. So
for the hydraulic plant contact an author­ized technician. Always utilise the new
hose supplied for connection to the water
supply. Old hoses must not be utilised.

The device needs to be supplied with
water that is suitable for human consump­tion and compliant with the regulations
in force in the place of installation. The
installation engineer needs confirmation
from the owner/manager of the system
that the water complies with the require­ments and standards stated above.

This unit must only be used for the pur­poses described in the present manual.
The manufacturer cannot be held respon­sible for any damages caused by improp­er, mistaken and unreasonable use.

2.1.2 CONNECTION TO THE WATERLINE

AND DRAINAGE SYSTEM

The machine requires stringent specifications to
prevent the formation of limescale and to ensure
quality beverages. The main features required to
achieve high standards of performance are the
following:

Total hardness

50 -60 ppm

Waterline pressure 2-4 bar, cold water

Minimum flow 200 l/hr

Filtration Less than 1.0 micron

Alkalinity
Total dissolved salts

10-150 ppm

50 -100 mg/L

(TDS)
Chloride < 0.5 mg/L

pH 6.5- 8.5

It is the task of a qualified technician to:
1 Adapt the water from the waterline to the

specifications required using filters and
water softeners;

2 Train the final user so that the equipment for

water treatment is constantly kept perfectly
operational.

The version with direct coupling is provided with
a loading tube 1,5 meters long with a 3/4 inch.
On one side is the fitting is straight and tapered,
the other angled at 90° with a gasket. The tube
is provided with tapered fittings therefore it is not
necessary to use Teflon tape on the fitting.

WARNING

If the water features do not comply, the war­ranty will automatically expire.

To connect the machine to the waterline, pro­ceed as follows:
1 Remove the pipe from the upper door “A”

and connect one of its ends to fitting “B”
situated on machine base.

2 Connect the other end of the pipe to the

waterline using a 3/8 fitting.
