7.4 Ordinary and Extraordinary Maintenance
The operations described in this section are purely indicative as they are
tied to variable factors such as the water hardness, humidity, products used
and workload, etc.
For all operations that require the disassembly of the distri -
butors’ components, make sure that the latter is switched off.
Entrust the operations mentioned here below to qualified personnel.
If the operations require that the distributor be switched on, entrust them
to specially trained personnel.
For more complicated interventions, such as removing the lime build-up in
the boilers a good knowledge of the equipment is necessary.
Monthly effect the debacterisation of all the parts in contact with food sub-
stances using chlorine based solutions following the operations already
described under chapter 4.5.2.
7.2 Product loading
When necessary provide for the loading of the products and/or consumption
materials of the automatic vending machine. For these operations please
refer to the operations described under chapter 7.7.
Remove and thoroughly wash all parts shown in Fig. 7.9:
– funnels and powder chutes (pos.1)
– water funnel (2), mixing bowls (3), whipper assembly (4) and lock nut (5)
– silicone water dispensing tubes.
– coffee funnel and chute (Fig. 7.10)
Before effecting the re-assembly operations clean all the elements carefully.
– remove all coffee powder residue; the unit can be removed from its hou-
sing to make the task easier (Fig. 7.11)
7.1.3.1 Cleaning the dispenser unit
– proceed with the instructions in section 4.6 to access the cup column
where the dispenser unit is located underneath.
- Raise the tabs (Fig. 7.1) to release the lower part of the dispenser unit
and remove the tray (Fig. 7.2).
- Lower the lever at the rear, then move the unit to the left and remove
it (Fig. 7.3).
7.1.3.2 Cleaning the sugar dispenser
- Release the securing spring as shown in figure 7.4.
Component A can now be removed using the screws in position 1, and
components B and C shown in Figure 7.5, in addition to the container
(Fig.5.6), allowing cleaning to be carried out.
7.1.3.3 Cleaning the nozzle holder
Loosen the knurled screw (Fig. 7.7) and remove the nozzle holder to clean.
The steam extraction tube can be removed completely by loosening the
knurled nut shown in figure 7.8.
7.4.1 Access to internal parts
To access the internal parts of the automatic distributor (pumps, espresso
coffee boiler, electrovalves, electrical connections,etc.):
- Turn the column unit towards the outside (see figures 4.20- 4.21 and
4.22).
- Then, using the two handles, remove the panel, supporting it until it has
been removed completely (Fig. 7.14).
After performing any maintenance operations raise the complete panel until
it is in the correct vertical position and put the column unit back in the ope-
rating position by turning it to the right.
7.3 Product tag replacement (Fig. 7.12)
To replace products tags, loosen the knurled screw (1 - Fig. 7.12) on the
inside of the front door.
Disconnect the illumination LED (2).
Remove the panel (3) and proceed with the replacement.
Reassemble everything after replacing the tag.
COFFEE MACHINE TIMING CHECK PROCEDURE
Ensure that during the idle state, the rotating index is aligned with the stage
index (see fig. 7.13)
Ensure that during the delivery stage that the rotating index is not more than
1.5 mm in advance of the delivery reference point (the rotating index must
be at a delivery position of between 0 and 1.5 mm from the delivery point).
7.5 MAINTENANCE PROCEDURES

and the formation of condensate or mould on the surfaces of the machine.
- It is also important that the premises where the distributor is installed
can guarantee a correct hygienic procedure, also preventing any cross
contamination, during the operations, between food, equipment, mate-
rials, water, air recirculation or personnel interventions and excluding any
external contamination agent such as insects or other harmful animals.
- Make sure that the water system complies with EEC Directive 80/778
regarding the quality of water for human consumption.
