WARNINGS FOR THE USER
- This equipment must not be used by children or by people
with physical, mental or sensory impairments, or by people
lacking experience, unless they be supervised by someone
responsible for their safety, or they received instructions
regarding the correct and safe way to use the equipment
and were warned of the risks.
- Never try to repair the equipment by yourself: you may
cause damage. Ask your seller for assistance.
- Never touch or use the water softener with wet or damp
hands or feet, or barefoot.
1) INTRODUCTION AND GENERAL INFORMATION
1.1 SCOPE OF THE USER MANUAL
This operation handbook is meant for well-trained personnel,
who is aware of power safety as well as sanitary regulations
on installation location. This manual aims at providing useful
information and insights to installers and users alike. Such
information focuses on:
power and sanitary safety measures
- equipment description and features
- place and installation procedures
- how to put the watermeter into service
- operation setting
- periodic resin regeneration
- instructions on equipment maintenance and cleaning
- disposal
- troubleshooting of any problems
This handbook is also intended to specify installers' as well as
users' accountability so as to prevent any equipment misuse.
Therefore, it is strongly recommended that you read this
manual before installing and using the appliance.
Failure to comply with the illustrated instructions implies lifting
manufacturer liability with respect to damages caused to peo-
ple, objects or animals; thus voiding equipment warranty.
1.2 MANUAL STORAGE
This handbook is an integral and essential part of the product.
It shall be stored with care by the user and shall always
go with its equipment, even in case the equipment is
going to be sold to another owner or user.
1.3 EQUIPMENT ID
This equipment is identified by figures in bold printed on the
label that is located in the lower left side of the gearcase (see
fig. 3, E) and at the back of this handbook.
1.4 DECLARATION OF CONFORMITY
This equipment is manufactured in compliance with EU
Regulations and with domestic laws in force at the time it was
launched on the market. As this equipment is not covered by
ANNEX IV in the 2006/42/EC DIRECTIVE, the Manufacturer
has carried out the self-certification steps for affixing the EC
marking on the label stuck on the gearcase.
The declaration of conformity signed by the Manufacturer is
available upon request and on the manufacturer website.
1.5 USEFUL INFORMATION AND ASSORTED NOTES
The Manufacturer cannot be held liable for any damages
and/or accidents that might be caused by non-complian-
ce of the above mentioned measures.
• For storage
- The regenerator shall be stored in a dry place. Storage tem-
perature shall range from 4 °C to 35°C.
• For installers
- Prior to installing the equipment, we recommend that you

carefully read the operating instructions in this manual.
Moreover, in case of problems, we suggest asking your
dealer for technical support. Dealer contacts are in the last
page of this handbook.
2) EQUIPMENT OVERVIEW
2.1 OPERATING PRINCIPLE
This equipment is designed to regenerate the resins in the
cylinders of the "ER" series softeners. By connecting the de-
pleted cylinder (fig. 1, C) to the regenerator and pressing the
button (fig. 3, A) the automatic regeneration cycle will
START
start. The regeneration cycle being completed, the cylinder
is ready to be used again. For proper regeneration, a large
quantity of salt in the brine tank is important (fig. 1, D); in fact,
the effect of salt water passing through the depleted resins is
to get them back to their active state.
2.2 RESIN REGENERATION PROCESS DIAGRAM
The cationic resins in the softener cylinder are able to tran-
sform calcium carbonate (scale) into sodium carbonate, which
is water soluble especially in the water temperatures that are
typical for coffee machines and ice-makers.
The ongoing release of sodium ions – which, incidentally, are
crucial in order to soften drinkable water - by resins tends to
decrease based on the actual flow rate and water consump-
tion up to their total depletion. This explains why they need
regeneration; a procedure that is based on the flow of water
and kitchen salt through the depleted resins so as to get them
back to their active state. The cationic function of resins, as
said, is gradually decreased based on how many times they
have been reactivated. Needless to say, this gradual process
makes them less efficient, and that is why resins shall be
replaced after seven years of use.
Salt is applied thanks to salt water suction during the regene-
ration cycle. During regeneration, resin disinfection is carried
out so as to counter any bacterial load.
We hereinafter include the chemical reactions taking place
during regeneration:
