- adjust the water flow in such a way as to completely
dissolve the salt in 10 litres water within 25 minutes;
- during the regeneration operation, ensure that the
softener unit is always full of water, bleeding any air
which may have entered;
- at the end of this operation ensure that outlet water is no
longer salted; it is advisable to check the hardness of the
water by means of appropriate chemical reagents, the
outlet water hardness should be 0°fH.
ANNUAL SANITISING
At least once a year, or more frequently according to the
use of the machine and the quality of the inlet water, the
entire foodstuff circuit system must be cleaned and
sanitized in the following way:
- all parts of the hydraulic system in contact with food,
must be removed from the unit and fully disassembled;
- wash all parts with detergent being sure that all visible
residue and product layers are mechanically removed,
using a brush if necessary;
- all components must be soaked in a sanitising solution
for at least 20 minutes;
- the unit internal surfaces are to be cleaned with the same
sanitising solution;
- thoroughly rinse and then reinstall the parts.
Before restarting the machine, the same sanitising
procedure described in section “Sanitising the mixers
and the foodstuff circuits” should be repeated.
PRINTED BOARD FUNCTIONS
AND INDICATOR LAMPS
CONTROL BOARD
This board, placed at the back of the machine, (see Fig.
17) processes the information from the push-buttons and
from the payment system; it also controls the actuations
and the push-button board.
The 15 V AC voltage required for board operation is
supplied by a transformer which is protected by a 160 mAT
fuse on the primary and by a 1.25 AT fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.
The board houses the EPROM (see Fig. 17 -3).
- the yellow LED indicates the presence of 12 V DC;
- the green LED blinking indicates that the microprocessor
is working correctly;
- the red LED indicates the operating status of the boiler
heating element.
