Regeneration Of The Softener Unit; Annual Sanitising - Necta Colibri Installation, Use And Maintenance Handbook

REGENERATING THE SOFTENER UNIT
(O )
PTIONAL
Only a 2-litre ion-exchange resin softener unit can be used
on these machines.
The resins should be regenerated at least once a week or
even more frequently depending on the hardness of the
water from the mains used to supply the machine (see
table below).

To regenerate the resins correctly do as follows:
- remove the softener unit from the cabinet and shake it
vigorously to eliminate any preferential paths which may
have formed;
- fill 0.5 Kg. of sodium chloride (ordinary table salt);
- connect the side hose union to a tap and the middle
rubber-holder to a drain point; the direction of the water
flow must be

- 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 sof-
tener 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 sani-
tized 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 mix-
ers and the foodstuff circuits" should be repeated.
