Regenerating The Softener Unit; Annual Sanitising - Necta Colibri Installation - Use - Maintenance

REGENERATING THE SOFTENER UNIT

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 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° F.

ANNUAL SANITISING

(O )
PTIONAL
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
sanitised in the following way:
- all parts of the hydraulic system in contact with food,
including the hoses, must be removed from the unit
and fully disassembled;
- wash all components with detergents, ensuring that all
visible residue and product films are mechanically
removed using brushes or similar tools, 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 unit, the same sanitising pro-
cedure described in section "Sanitising the food-
stuff circuits and the mixers" should be repeated
with the components reassembled.
