Resin regeneration
(climatic chambers about 250,
340, 600 l)
• Regeneration of the ion exchange resins con-
tained in the softener D must be carried out
regularly depending on how hard the mains water
supply is to which the
machine is connected.
In order to carry out regen-
eration correctly, proceed as
follows:
• Remove the softener from the
machine and shake it hard to
eliminate any rivulets that
may have formed;
• Put in 1 kg of sodium chloride
(common salt);
• Connect the upper pipe
holder to a tap and the lower
pipe holder to a drain; the
water MUST flow in the
direction shown in the
diagram;
• Adjust the water flow so that
the salt will be completely
dissolved by twenty litres of
water in 35 minutes.
• During regeneration, check
that the softnener is always
full of water and any air that
has formed is removed;
• When the operation has
finished, make sure that the
water coming out is no longer
salty; we advise using special
chemical reagents to check
that the level of outlet water
hardness measures 0
°
F.
• According to water hardeness.
