Make sure that you fully uncoil the power
supply cable and check that it is not crushed in
any way.
Should the supply cable be damaged, it
must be replaced by a specialized technician
using a special cable available from the
manufacturer or from the Technical Service
Centers.
5.4 CONNECTION TO THE WATER MAIN
This appliance must be only be supplied
with cold water for human consumption
(drinking water).
The operating pressure must be between 0.1 and
0.6 MPa.
The appliance must be connected to the water main
by professionally qualified personnel in accordance
with the manufacturer’s instructions.
A tap must be installed between the water
mains and the feed pipe of the appliance, so that
the water supply may be shut off if necessary.
Where the feed water is particularly hard, you are
advised to install a softener. Any solid particles (e.g.
sand) may be eliminated by installing a mechanical
filter, which must be periodically inspected and
cleaned.
These devices must comply with the
standards in force in the country of use.
Never turn the water supply tap off when
the appliance is working.
5.4.a FILLING WITH WATER (Fig. 7)
Insert the special seals provided (18) in the two
threaded ring nuts of the water feed pipe (11)
supplied with the appliance.
Without exerting excessive force (otherwise the
unions could crack), firmly tighten one of the
threaded ring nuts on the outlet of the solenoid val-
ve located in the rear of the appliance (
front for
the completely built-in model
). The other threaded
ring nut must be screwed to the water tap (10); this
too must be provided with a thread.
5.4.b DRAINAGE (Fig. 7)
Fix the water drainage pipe (12 Fig. 7) in the housing
provided on the rear of the appliance (
front for the
completely built-in mode
l). Make sure that:
•
The pipe is a hose.
•
The internal diameter is 22 mm, as required.
•
The water drainage hose is not throttled at any
point throughout its length.
•
The drainage hose slopes downwards by at
least 15%.
It is advisable to drain the water straight into an open
drain trap.
6 START-UP
6.1 CLEANING INTERNAL PARTS
The appliance will have already been cleaned in
the factory. However, you are advised to wash the
internal parts again before using the appliance.
Make sure that the power supply cable is unplugged
before carrying out the above cleaning operation.
For cleaning operations in general, use an ordinary
detergent for washing dishes or a solution of water
and vinegar. Rinse thoroughly with plenty of cold
water and remove any ice that may have been
produced during the initial cycles.
It is advisable to avoid using abrasive detergents or
powders, since these might damage the finish. (For
further information regarding cleaning of internal
parts, refer to Point 9.3 of this Instruction Manual.)
6.2 START-UP (Fig. 8)
When you start up the appliance the first time,
or when you start it up again after a long period
at a standstill, pour three liters of water into the
internal basin.
This filling operation must be carried out by
raising the flaps (20) and pouring the water
directly into the internal basin.
In the cycles subsequent to the initial one, the
appliance will be filled with water in a fully automatic
way.
Once the above operation has been performed,
proceed as follows:
•
Turn on the water supply tap 10 (Fig. 4).
•
Switch on the power supply by means of the
relative switch fitted during the installation
phase.
