8. INSTRUCTIONS FOR THE REGENERATION OF THE WATER PURIFIER
Important:
Regeneration must be done every 15 days in case of a daily coffee consumption between 1 and 2
kg. If consumption is higher, regeneration must be done in a weekly basis.
Carefully follow the instructions for regenerating the purifier.
1. Place a container with at least 2 litres capacity under tube E. Turn handles C and D from left
to right. (Picture 8.1)
2. Remove cover by releasing knob G (Picture 8.1) and put 1 kg of salt (ordinary kitchen salt) in
the 8 litres purifier and 2 kg in the 12 litres purifier. Put cover back in place and turn handle
C from right to left (Picture 8.2) so that salt water flows through tube F. When water becomes
sweet, turn handle D from right to left again (Picture 8.3).
Attention: This regeneration operation is extremely important
If the purifier resins are not regenerated, the consequence will be limestone deposits formation in
the boiler, electrovalves and all hydraulic circuit. Those deposits will influence the performance and
reliability of the machine and can also cause severe damage. Therefore it is necessary to execute
maintenance procedure. This kind of intervention is not covered by warranty and it is a responsibility
of the machine's owner.
