Example of a recommended cleaning procedure:
The person responsible for machine hygiene, before opening the distributor
must check the cleanliness of the surrounding environment and put up a sign
to tell any potential consumers that:
-
the machine is "out of use as maintenance is in progress"
-
it is important that the person responsible for cleaning never has to in-
terrupt his work in order to operate the machine.
6.1.2
Periodic cleaning by the maintenance technician
First step: disposal of the waste inside the waste bins (paper, tissues,
cans, etc).Once the waste has been disposed of it is possible to clean the
surrounding area.
-
elimination of the coarse dirt
-
disinfecting of the flooring and walls of the area surrounding the machine
up to a radius of 1 metre around the distributor
-
once this is complete proceed with opening the distributor.
6.1.3
Cleaning and maintenance
The aim is to prevent bacteria from forming in the area in contact with
foodstuffs.
For all cleaning operations follow the instructions indicated in para-
graph 6.1.1.
Operate as follows:
– dampen a cloth and clean all the visible parts of the delivery area (Fig.6.1)
– using specific products, clean the door glass inside and outside (Fig.6.2).
Refrigeration system cleaning
– keep the radiator and the ventilation grilles clean using a vacuum cleaner.
If this operation is not carried out correctly and regularly, the refrigeration
system may be damaged irreparably.
6.1.4 Ordinary and Extraordinary Maintenance
The operations described in this section are purely indicative as they
are tied to variable factors such as the 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.
6.2 Adjustments
6.2.1 Spirals
It is possible to modify the position of the spiral end by pulling it forwards
until the geared motor panel comes out.
Rotate the spiral until the ideal position is found.
Release the spiral which will return to its housing because of the spring effect.
Each spiral can rotate by 45° at a time (see fig.6.3)
6.2.2 Spiral replacement
It is possible to replace the spirals with others with a pitch that is suitable for
the product to be delivered. To carry out this operation, proceed as follows:
-
rotate the spiral in a clockwise sense until it is released on the dragging
cam (Fig.6.4)
-
bend the spiral downwards slightly and pull it outwards.
For reassembly:
-
couple the spiral behind the notch on the cam (Fig.6.4-pos.1).
-
introduce the spiral in the slot on the cam (Fig.6.4-pos.2).
6.2.3 Change the number of spirals per drawer
It is possible also to change the number of spirals per drawer up to a ma-
ximum of 8 spirals.
To replace the Ø 80 spiral with two Ø 68 spirals, operate as follows:
-
replace the Ø 80 spiral with the Ø 68 spiral of required pitch.
-
move the motor to the first slot on the left.
-
remove the column guide.
-
assemble a new motor in the slot on the right of the original slot.
-
connect the feed wiring to the motor
-
insert a separator between the two spirals.
Each can have 4, 6, 8 spirals arranged according to the following model:

The distinction between an 8-spiral drawer and a 4-spiral drawer will be
effected with an automatic test which is carried out every time the machine
is switched on.
For the opposite operation it is necessary to:
-
disconnect the motor of the odd selection (11, 13 etc.)
-
remove it from the drawer
-
remove the spiral separator
-
move the even selection motor (12,22 etc.) by one slot to the left
-
replace the Ø 68 spiral with the Ø 80 spiral of the required.
apply the guide under the spiral, taking care to bend the clamp tabs
-
again.

6.2.4 Change height between drawers
To change the distance between one drawer and another, it is necessary to:
-
remove the drawer completely.
-
remove the right and left guides of the drawer by unscrewing the securing
screws.
-
position the guides in the slots according to the required height, coupling
them behind first and securing them with screws.
-
in the same way, raise or lower the drawer connector on the bottom of
the bin.
6.2.5 Accessories
Certain accessories are available which can be applied on the spirals (expellers
see fig.6.5) to aid product release.
The expeller is applied in the first part of the spiral and acts like an exten-
sion of this spiral bringing the product to the edge of the drawer to help it
to fall correctly.
-
it is possible to introduce guides parallel to the spirals for narrow and high
products (see fig.6.6) in order to reduce the space between the product
and the walls of the section.
-
or supports (see fig.6.7) to help the products to slide.
6.3 Inactivity
For prolonged distributor inactivity it is necessary to carry out certain pre-
ventive operations:
– disconnect the distributor electrically
– unload all the products from the trays (Fig.6.8)
– wash all the parts in contact with foodstuffs in accordance with the above
descriptions
– clean all the internal and external surfaces of the automatic distributor
with a cloth
– protect the outside with a cellophane film or sack (Fig.6.9)
– store in dry sheltered rooms with temperatures no lower than 1°C.
7.0 DISMANTLEMENT
Proceed with the emptying of the products and of the water as described in
the previous paragraph.
For the dismantlement we advise to disassemble the machine dividing the
parts according to their composition (plastic, metal etc.).
Subsequently entrust to specialised companies the parts divided in this
manner.
If there is a cooling unit, give the latter, without disassembling, it to specific
companies authorised for the scrapping of the unit in question.
Attention! Check that the machine disposal is perfomed with respect of en-
vironmental rules and according to the regulations in force
