DOUBLE BOILER
At the output of the lines, the distributor will be put in condition
of FIRST INSTALLATION. As it reaches the location the operator
will link only water (both in the case of linking to the mains and
autonomous tanker) and the mains.
The distributor, in condition of resistances OFF, will automatically
require water and will open the electrovalve 2 to vent the air which
is in the stainless boiler. This condition will last 200 seconds. At
the end of this timeout, the distributor will close the electrovalve
2 and the water input ev for 20 sec. After this time water loading
will continue until the micro lack of water is N.C. for a time excee-
ding 5 sec (this operation is linked to a second timeout of 200
seconds). In this condition the D.A. activates the electrovalve 2
and will supply 20 sec of water. At the end of the supply, the micro
lack shall return to N.C. After 10 sec D.A. activates the expresso
pump, and, on condition of resistance OFF, it will supply 20 cc of
water through the coffee ev (measured through the fan). After
this procedure, the distributor installation date is stored. When
the date is confi rmed, D.A. waits 10 seconds and soon after it will
start to heat up water in the 2 boilers.
4.5.3 Filling the cooling unit
Where foreseen , for the fi lling of the cooling unit operate as fol-
lows:
– Remove the cap positioned on the top plate of the cooling unit
and insert the instant boiler drain hose which is positioned along
the liquid waste chute.(Fig.4.18).
– Position the reservoir drain hose in the liquid waste bin, in the
(Fig.4.19).
– Insert the key in the door switch (see Fig.4.12) and wait until
water fl ows out of the drain hose.
– Remove the door switch key
– Disconnect the instant boiler tube and replacing the cap and
position again along the chute.
– Connect the refrigerating group electrically (insert into the
junction box the blue wire n. 18) (Fig. 4.20)
– Wait for the soluble produce heater to fi ll up
– Make the necessary selections in order to fi ll the hydraulic cir-
cuits
– Wait for thirty minutes until the temperature of the refrigerating
group reaches regime and i.e.:
– The thermostat has already been calibrated by the manufacturer
in order to obtain the following temperatures:
water in the reservoir about +4°C
drinks about +6/ 8°C
At the end of the water
fi lling, effect a cleaning
cycle of the mixer group
so as to fi ll all the circui-
ts and remove eventual
residues from the boiler
(Fig.4.17).
Before connecting the
power supply, ensure
that the distributor has
been connected to the
water mains and that
the water tap has been
turned on.
