In both cases, a differential switch must be arranged upstream of
the power supply cable, complete with magnetic release switches
compatible with the data provided on the machine rating plate.
The relative contacts must be provided with an opening equal or
greater than 3mm.
We hereby remind that each machine must be provided with its
own, individual safety devices.
In the event that the power supply cable is damaged, it
must be replaced either by the manufacturer, by the manu-
facturer's technical services or by qualified personnel that
is capable of preventing any possible hazards.
5.1.2 Water mains supply (Fig. 5.2 and Fig. 5.3)
The water mains connections must be arranged to be in the vicinity
of the machine.
· Liquid ground collection tank discharge tube
· Water supply tube
5.2 Machine positioning
·
Position the machine unit onto the horizontal surface as arran-
ged, then carefully adjust height via the adjustable feet. Ensure
that the machine is not inclined at an angle larger than 2°.
Prior to proceeding with the connection, accurately wash out the
water mains tubes:
·
open the mains water tap completely and let the water run for
a few minutes.
·
Proceed with connecting up the inlet and outlet water connec-
tions.
·
Hook up the machine to the electrical power mains.
Proceed with accurately washing out all the machine water pi-
pes:
·
Open the water mains supply tap completely.
· Switch on the main switch (item 1) and wait until the boiler fills
up to set level
·
Switch on the main switch (item 2) to start heating up of the
water in the boiler.
·
Activate all the groups so that they discharge water for about
a minute. Repeat this operation twice.
Wait until the machine has reached the required pressure level
(about 40 minutes)
·
Proceed with discharging steam from the steam spouts for about
one minute.
·
Discharge hot water from the hot water dispenser pipe for about
a minute. Repeat this operation twice.
·
Switch all the switches back off again.
For optimised machine operations we recommend the
use of a water treatment/lime scale eliminator unit to be
connected up prior to entry of the mains water into the
machine.
If the machine has not been dispensing for longer than 24
hours, prior to starting operations proceed with washing
out all the internal components by repeating all the opera-
tions listed above.
