Installing the water inlet pump in machines equipped with a water
softener
The installation of the water inlet pump in machines equipped with a water softener is
carried out in the same way as in machines that do not have a water softener, except
for the pump outlet coupling, which has to be connected to the silicon tube going to the
water softener inlet nozzle (see assembly circuit)
6.12.2.- Water softener.
Basic water softening concepts
May waters contain dissolved minerals that make it hard (calcium or magnesium).
These minerals create scale deposits. For the coffee machine to work properly, as well
as to make maintenance operations easier, it is necessary to use low scale content
water. Otherwise, the scale accumulates on the various machine components and may
obstruct conduits and deteriorate parts or render them ineffective. If you cannot connect
the machine to a soft water supply, a water softener will eliminate hard water problems
by exchanging calcium and magnesium ions with sodium ions, thanks to the resins of
the water softener filter. It is advisable to use a water softener filter for water with a
hardness level above 20 °FF (French degrees). The JOFEMAR coffee machines can be
fitted with an optional ion exchange resin filter water softener. These filters are based on
the capability of the resins inside the water softener bottle to exchange sodium (Na)
ions with calcium (Ca) and magnesium (Mg) ions in the water. With use, the resins
become saturated with and need to be regenerated. This is achieved by putting
common (kitchen) salt in the water softener bottle and passing water through the resin,
so the salt’s sodium is trapped in the resin and the calcium and magnesium ions are
discharged. How long a filter will last before it needs to be regenerated depends on the
water’s hardness. The number of approximate drinks (which depends on how much
water is needed for each product) that these filters can handle are:
