Softener Regeneration; Softener - Wega LB 4700 Manual De Uso Y Mantenimiento

9. SOFTENER (optional)
Mains water contains insoluble salts, which cause the build-up of lime scale deposits in the boiler and in other parts of the
machine. The softener makes it possible to eliminate or substantially reduce the presence of these mineral salts.
The resin softener has the property of retaining the calcium contained in the water. For this reason, the resins become saturated
after a certain period and must be regenerated with coarse kitchen salt (NaCl, sodium chloride) or special water softening salt. It
is very important to regenerate the softener within the established times.
The regeneration is to be done regularly every 15 days. However, in locations with very hard water, it will be necessary to
regenerate more frequently. The same is true of places in which there is a large consumption of hot water for tea or other uses.

Softener regeneration

Proceed as follows:
• move the levers (2) and (5) from left to right;
• remove the lid by loosening the knob (1);
• release enough water through the pipe (3) to make room for the amount of salt as required depending on the model (see
table);
• clean any salt or resin residue from the gasket located on the lid;
• put the lid back in place by screwing the knob (1) down securely and move the lever (2) back from right to left.
• let the salt water drain from the small tube (4) until the water is no longer salty (about 30-60 minutes). The salt allows the
accumulated mineral salts to be released;
• move the lever (5) from right to left back to its initial position.

The build-up of lime scale in the hydraulic circuit and boiler inhibit thermal exchange, thus compromising
proper operation of the machine. Heavy incrustation in the boiler may cause long machine shutdowns
and in any case invalidate any guarantee, because this symptom indicates that regeneration has been
neglected .
In order to keep the softener and hence the machine in
perfect operating condition, it is necessary to perform
regeneration periodically based on the use of the softener
and the hardness of the water that is used.
The table alongside shows the quantity of softened water
based on the hardness of the water in the various units
of measure:
- f°: French degree
- D°: German degree = 1.8 °f
- mg CaCO
