3 to 4 bars).
• If water pressure exceeds 8 bars installing a pressure regu-
lator is advisable.
3.3 CONNECTION TO THE WATER SUPPLY SYSTEM
Connection to the water supply system shall be carried out in
compliance with legislation in force and with the instructions
set by the manufacturer. Moreover, resorting to qualified tech-
nician is advisable.
In the installation phase, any pipe, coupling, valve and compo-
nent used shall be DM 174/2004 compliant. We recommend
preserving components’ hygiene integrity by keeping them in
their original packaging up to their actual installation.
Using components and materials that are not suitable for
drinkable water contact is forbidden just as it is forbidden to
use materials that are stored without complying with sanitary
rules, as they could jeopardize the quality of treated water and
damage the equipment.
Please consider the following:
- the infeed water pipe shall measure at least 7 mm (fig. 6, F)
as inner diameter.
- installing a non-return valve on the outflow pipe (fig. 6, B)
(DVGW, DIN 1988 T2). This protects the softener from any
hot water flowing back as this could damage the equipment.
- check that all the pipes are free, not squeezed and unclog-
ged.
- Connect the inflow water pipe to the tap (fig. 6, E, F).
- Connect the outflow coupling to the non-return valve and to
the outflow pipe (fig. 6 A, B, C).
- Connect the inflow tap and coupling to the valve by moun-
ting them up to the mechanical stop (fig. 7).
- Turn the knob to “REPLACE” (fig. 4, A) and slide the two
pins outward (fig. 4, B), open the water tap and check that
no leakages are present.
- Connect the small drain pipe (fig. 6, G).
3.4 QUICK PIPE COUPLINGS
Pipe connections to the valve are based on quick pipe cou-
plings.
For proper pipe connection, the installer shall push it up to
the mechanical stop. The metal parts of the quick coupling
prevent the pipe to slip out of its housing.
Press the black ring around the coupling and slip off the pipe
if you want to disconnect the pipe or the tap (fig. 7).
4) MAINTENANCE TO BE CARRIED OUT BY THE INSTALLER
4.1 PUTTING INTO SERVICE / REPLACEMENT
Make sure that either the ERV valve or the cylinder have no
defect or damage caused by transport before installing this
equipment. In case of problems, call the dealer.
Cylinder put-into-sercice and replacement procedures are
quite similar.
4.2 INSTRUCTIONS ON CORRECT CYLINDER
PUT-INTO-SERVICE / REPLACEMENT
1. Make sure that you position the drain pipe in a catch basin
or, as an alternative, use a bucket with at least an 8-litre
capacity, in order to drain the water needed for putting
into service or replacing the equipment.
2. Make sure that the drain pipe (fig. 2, G) is correctly in-
stalled in the valve pipe holder (fig. 2, H). Put the other
end of the pipe in the catch basin or in the bucket. Note
that approx. 5 liters of water will be drained during such
procedure.
3. Rotate the ERV valve knob to REPLACE (fig. 4, A), then
wait for 10 seconds.
4. Slide the two side blocks outward to put them in the open
position (fig. 4, B). Uninstall the valve from the depleted
cylinder (fig. 4, E).
5. Install the valve on the regenerated/new cylinder (fig. 4, G)
making sure that the pin matches the hole in the cylinder
collar (fig. 4, C).
6. Slide the two side blocks inward so as to lock them (fig.
4).
7. Turn the knob to WASH (fig. 5) and drain approx. 5 liters
of water from the drain pipe. Please check if the drained
water is clear.
8. Turn the knob to SERVICE (fig 3).
9. Make sure that water is not flowing out of the drain pipe
and that there are no water leakages.
10. Please jot down the service start date on the cylinder label
(fig.1, C).
4.3 REGENERATION – STORAGE
Once the depleted cylinder is replaced, the operator shall
regenerate it by using the dedicated regeneration equipment.
Once regenerated, the cylinder can be stored and used again.
Make sure that the actual regeneration date is recorded so as
to track the cylinder life cycle.
We recommend to not regenerate cylinders more than 10
times; once that threshold attained, we suggest to replace
them.
The cylinder shall be regenerated by exclusively using the ERA
equipment.
- STORAGE
- If cylinders are stored for more than 6 months, resin
regeneration shall be carried out by using the “
ERA
REGENERATION SYSTEM
” before putting them into ser-
vice.
We recommend carrying out a regeneration and a resin
rinse cycle before installing a new cylinder.
- If a cylinder is installed but has not been used for more
than 4 months, we recommend that you do not use it un-
less a rinse cycle is first carried out.
5) ADJUSTING WATER HARDNESS
BY USING A MIXING PIECE
The mixing piece (fig. 3, A) features a screw which, when
gradually worked loose, increases hardness in the outflowing
water.
Mixing increases by loosening the screw. Such procedure
shall carefully be carried out; at the end of this adjusting pro-
cess, let water flow and check water hardness.
Note: water hardness shall be checked on a regular base by
the installer.
6) EQUIPMENT MISUSE
This equipment has been designed in order to soften drin-
kable water to be used in technological appliances.
The equipment shall not be used for other purposes, neither
shall it be modified or tampered with.
Any use that is not illustrated in this manual is deemed unsui-
table and consequently dangerous.
The Manufacturer cannot be held liable for any damages and/
or accidents that might be caused by non-compliance with se-
curity measures and by unsuitable, wrong and unreasonable
equipment use.
• Do not feed the equipment with liquids other than drinkable
water.
• No products or substances other than water and sodium
