15 - USE OF THE SOFTENER
Calcium and magnesium contained in the water circulating inside the
boiler and brewing unit circuits damage the machine. The softener
dissolves the calcium and magnesium, which settle on the resins
therein contained.
To prevent the build-up of deposits from saturating the resins, thus
limiting their functions, these need to be regenerated at regular inter-
vals according to the following criteria:
- 8 litre softener for 40 French degree hardness water
• up to 400 cups of coffee/day, every 10 days
• up to 800 cups of coffee/day, every 5 days
• up to 1000 cups of coffee/day, every 3 days
- 12 litre softener, for 40 French degree hardness water
• up to 500 cups of coffee/day, every 15 days
• up to 1000 cups of coffee/day, every 7 days
• up to 1500 cups of coffee/day, every 5 days
• up to 2000 cups of coffee/day, every 3 days.
Failure to comply with the above regeneration timings will prejudice
the thermal and mechanical functions of the machine and the taste of
the coffee, owing to the formation of scale.
For regeneration, proceed as follows:
Place an empty container, having a capacity of at least two litres,
under pipe e, turn the c and d handles to the right, unscrew the g
lid and wait for the water to fully flow out of pipe e, Introduce 1.5
Kg. of cooking salt for the 8 litre model or 2 Kg. of salt for the 12
litre model, place the lid back in place and move the c handle from
right to left; let the salted water flow out of the f pipe and wait until
the water has become fresh again (the cycle takes approximately 90
minutes).
a. – Water inlet
b. – Water outlet
c. – Inlet tap
d. – Outlet tap
e. – Vacuum pipe
f. – Regeneration pipe
g. – Lid knob
Now move the d handle from right to left.
During regeneration, do not use the machine; for machines equipped
with automatic level indicator it is advisable to cut off the pump
power supply, to prevent no-load operation.
Before connecting the softener to the machine, wash the resins, by
establishing a connection to the water mains and letting water run for
five minutes.
N.B. The above mentioned directions relate to the softener
shown in the pictures; if your equipment differs, follows the
directions attached to softener in question.
16 - MACHINE DEMOLITION
Should you decide to no longer employ the machine, owing to wear
or to other reasons, we recommend that, once you have removed the
plug from the socket, you deactivate it by cutting off the supply
cable.
As regards the demolition procedure, we recommend you separate
the various parts of the machine, depending on their nature (plastic,
metal, etc.). Hence employ specialised firms for the disposal of the
various parts.
