Before connecting up the hoses, remove any
rubber plugs inserted in the inlet/outlet
connectors on the AD 8 water softener.
Fig. 6: Connect up the water softener to the mains water
supply by attaching the hoses (23-22) to the inlet tap
(24) and water outlet tap (21) on the softener itself. Then
tighten the hose clips.
Connection to the water softener must only be
effected by qualified, authorised personnel.
Fig. 7: Connect the water outlet hose (26) on the softener
directly to an open siphon (this must be below the
softener).
Fig. 8: To ensure that the resin in the exchanger gives the
required performance rinse the softener by turning the
knob (25) to position number "4" (backflow position: see
fig. B) for at least 10 minutes until the water outflow is
perfectly clear.When doing this direct the water into the
open siphon (see fig. 7).
Fig. 9: Regenerate the water softener as explained in
section 6.6.1.
Improper regeneration of the water softener can
damage the steam generator. If you have any
doubts, please contact properly qualified personnel.
Fig. 10: Connect the other end of the softener hose (22) to
the water inlet connector (20) on the steam generator.
Fig. 11: Connect the other end of the softener hose (23) to
the mains water supply.
Make sure water pressure does not exceed 3/4
bar; it is advisable to fit a pressure reducer
calibrated to 1 - 2 bar.
Fig. 12: Connect the lead to the power mains: ensure that
connection is effected as per the instructions given in
section 6.4.
Fig. 13: Press the main switch (13): the LED on the switch
come on.
Fig. 14: Switch on pump and element by acting on switch
(14); the LED on the switch comes on, the "water low"
warning light 4) comes on and the pump starts working.
• When filling the first time, it is normal for the
pump to make some noise.
• It is advisable to install a tap between the mains
water supply and the water inlet hose of the
softener so that the water flow can be closed off
if necessary.

Failure to comply with any of the above-stated
equipment installation regulations can lead to
equipment malfunctioning and render the
warranty null and void.
6.6.1 REGENERATING THE AD 8 WATER SOFTENER - Fig. B
Regeneration frequency depends on how often
the AD 8 softener is used and the degree of purity
of the water. The installer will be able to provide
information regarding the hardness of the water
at the installation site.
To regenerate the AD 8 water softener proceed as follows:
• turn the water softener knob (25) to position 2. Loosen
the lid knob (27) and wait for the pressure to be
released.
• Remove the lid by unscrewing the knob (27), then
introduce the salt.
• Clean off any salt or resin that may have deposited on
the lid seal, replace the lid and screw it back in place
properly.
• Turn the knob (25) to position 3, and let the salt water
drain from the hose (26) until it becomes fresh (this
takes about 40 minutes).
• Turn the knob (25) to position 4, wait about 30
seconds, then bring the knob (30) to position 1. In the
intervening 30 seconds the unit will not be supplied
with softened water.
• When regeneration is being carried out the
steam generator connected to the softener is
still supplied with water, but the latter is not
softened.
• To maintain AD 8 water softener performance
use the chart enclosed with this manual to
record regeneration data.
Use only NaCl (common cooking salt) to
regenerate the softener. Do not use acid or basic
substances, solvents or chemical products.
