CLEANING THE WATER SOFTENER (A-K-S-C-B, no A-K with WTS)
1) Periodically clean the gigleur fitted on the lower water softener valve by unscrewing it
and ensuring that the water hole is not clogged.
2) Refit it on the valve and tighten it.
REGENERATION OF THE WATER SOFTENER RESINS
(A-K-S-C-B, no A-K with WTS)
After the water softener resins have removed a given quantity of calcium and magnesium
salts from the water (water hardness) they rapidly become saturated, losing their softening
capacity. This capacity is completely restored through regeneration, which is carried out by
washing in a salt and water solution.
The efficiency of the water softener will guarantee constantly good coffee quality as well
as the high performance and long life of the machine. Maintenance is also reduced as scale
deposits are not allowed to form in the hot water hydraulic circuit.
Regeneration must be carried out at a maximum frequency of once a week, depending
on the following parameters:
- Size of the water softener
- Hardness of the water
- Water consumption
If the size of the water softener is increased, regeneration may be done less frequently.
The opposite is the case if the other two parameters increase. As a general reference, with
an 8 litre water softener and a water consumption of approx. 25 litres per day, with a water
hardness of 30° French degrees, regeneration may be carried out once every 4 weeks.
If, on the other hand, the hardness of the water were 60° French degrees, it would have
to be carried out once every 2 weeks.
If a standard water softener with completely manual valves is installed, follow the
instructions below.
If semiautomatic or automatic water softeners are installed, follow the specific instructions
provided in the handbooks accompanying the water softeners themselves.
1) Switch off the machine.
2) Turn off the water supply.
3) Vent the softener’s internal pressure by turning the upper valve lever clockwise:
water will flow out of the semitransparent flexible pipe.
4) Close the discharge by returning the upper valve lever to the vertical position.
5) Open the softener upper cap.
6) Pour the following amount of common coarse salt into the softener:
- 8-litre softener 1,0 kg
- 12-litre softener 1,5 kg
- 16-litre softener 2,0 kg
