This leaflet is an integral part of the product.
Please read the warnings provided carefully as
these provide important information concerning
the safe installation, use and servicing of this pro­
duct. This water softener is intended to be used to
soften cold drinking water only, any other use is
considered improper and as such unreasonable.
WARNING: use only sodium chloride NaCl in lar­
ge grains (kitchen salt) for regeneration. The use
of any other chemical substances or products is
strictly forbidden.
The resins in the water softener are needed
for this to work properly: please do not throw
them away.
INSTALLATION
• After removing the packaging, make sure that
the water softener isn't damaged. Keep the
packaging materials (plastic bags, cardboard
box etc. ...) out of the reach of children as they
can be dangerous. The water softener should be
installed in full observance of the current laws,
following the manufacturer's instructions and by
experts. If installed incorrectly, the equipment
may cause injuries to people and animals and
damage to property, in which case the manu­
facturer cannot be held liable.
• Install the water softener in rooms where the
temperature is minimum 5°C and maximum
30°C (Centigrade).
CONNECTION TO THE WATER MAINS (figure
1)
• The user must install a tap between the water
mains and the water softener so that the water
can be turned off in an emergency, plus a check
valve to avoid any pressure returns.
• Connect the water inlet and outlet hoses to the
provided unions and make sure they are tighte­
ned properly.
• Place the hose in the joint and push it until it
stops. The metal elements of the quick con­
nection prevent the hose from coming out.
