WARNING & SAFETY INSTRUCTIONS

Before you begin the installation of the water softener, we advise you
read and carefully follow the instructions contained in this manual. It
contains important information about safety, installation, use and
maintenance of the product. The actual system that you have received,
may differ from the pictures/illustrations/descriptions in this Technical
Manual.

Failure to follow the instructions could cause personal injury or damage
to the appliance or property. Only when installed, commissioned and
serviced correctly, the water softener will offer you many years of
trouble-free operation.

The water softener is intended to 'soften' the water, meaning it will
remove hardness minerals; it will not necessarily remove other
contaminants present in the water. The water softener will not purify
polluted water or make it safe to drink!

Installation of the water softener should only be undertaken by a
competent person, aware of the local codes in force. All plumbing and
electrical connections must be done in accordance with local codes.

Before setting up the water softener, make sure to check it for any
externally visible damage; do not install or use when damaged.

Use a hand truck to transport the water softener. To prevent accident or
injury, do not hoist the water softener over your shoulder. Do not lay the
water softener on its side.

Keep this Technical Manual in a safe place and ensure that new users are
familiar with the content.

The water softener is designed and manufactured in accordance with
current safety requirements and regulations. Incorrect repairs can result
in unforeseen danger for the user, for which the manufacturer cannot be
held responsible. Therefore repairs should only be undertaken by a
competent technician, familiar and trained for this product.

In respect of the environment, this water softener should be disposed of
in accordance with Waste Electrical and Electronic Equipment
requirements. Refer to national/local laws and codes for correct recycling
of this water softener.

OPERATING CONDITIONS & REQUIREMENTS

OPERATING PRESSURE: min. 1,4 / max. 8,3 bar
 this system is configured to perform optimally at an operating
pressure of 3 bar (±½ bar); in case of a lower or higher operating
pressure the performance may be affected negatively!
 check water pressure regularly.
 take into account that night time water pressure may be
considerably higher than day time water pressure.
 install a pressure reducer ahead of the water softener if
necessary.

OPERATING TEMPERATURE: min. 2 / max. 48 °C
 do not install the water softener in an environment where high
ambient temperatures (e.g. unvented boiler house) or freezing
temperatures can occur.
 the water softener cannot be exposed to outdoor elements,
such as direct sunlight or atmospheric precipitation.
 do not install the water softener too close to a water heater;
keep at least 3 m of piping between the outlet of the water
softener and the inlet of the water heater; water heaters can
sometimes transmit heat back down the cold pipe into the
control valve; always install a check valve at the outlet of the
water softener.

ELECTRICAL CONNECTION: 230V-50Hz
 this water softener only works on 24VAC; it is equipped with a
230/24V-50Hz transformer; always use it in combination with
the supplied transformer.
 make sure to plug the transformer into a power outlet, which is
installed in a dry location, with the proper rating and overcurrent protection.

 If the water softener is not equipped with the factory
bypass (optional), we strongly recommend to install a 3valve bypass system (not included with this product!) to
isolate the water softener from the water distribution
system in case of repairs. It allows to turn off the water to
the water softener, while maintaining (untreated) water
supply to the user.

1. Connect a 13 mm hose to the drain solenoid of the control
valve (); secure it by means of a clamp.
2. Run the drain hose to the sewerage system and connect
it to the stand pipe assuring sufficient air gap. This drain
line operates under pressure, so it may be installed higher
than the water softener.
3. Connect a 13 mm hose to the cabinet overflow elbow,
located at the back side of the water softener; secure it
by means of a clamp.
4. Run the drain hose to the sewerage system and connect
it to the stand pipe assuring sufficient air gap. This drain
line does NOT operate under pressure, so it may NOT be
installed higher than the water softener.

MAINTENANCE
 = inlet valve to water softener is OPEN
 = outlet valve from water softener is CLOSED
ROUTINE CHECKS
Regularly the user should perform a basic check to verify if the
water softener is functioning correctly, on the basis of the
following control points:
1. Check settings of electronic control panel.
2. Measure water hardness before/after water softener.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless water softener is in regeneration).
4. Check drain line from cabinet overflow; there shouldn’t
be any water flow.
5. Check water softener and surrounding area; there
shouldn’t be any water leakages.
WATER CONDITIONER SALT
Picture 10
The water softener needs 'brine' for its periodic
regenerations. This brine solution is made from water, that is
automatically dosed in the brine cabinet by the control valve,
and water conditioner salt. The user should make sure that
the brine cabinet is always kept full of water conditioner salt.
Therefore he should periodically check the salt level inside the
brine cabinet and refill it if necessary. The salt lid can be
removed completely to facilitate refilling.
BYPASSING THE WATER SOFTENER
Ideally the level of water conditioner salt inside the brine
cabinet is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufficient brine saturation,
resulting in a loss of softening capacity. A higher level of water
conditioner salt can cause salt bridging (hard crust or salt
bridges in the brine cabinet). When you suspect salt bridging:
 carefully pound on the outside of the brine cabinet to
break loose the salt bridges;
 using a broom (or like blunt tool) carefully push the salt to
break it apart;
 pour warm water over the top of the salt to dissolve it.
Occasionally it may be necessary to put the water softener
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
 in case of an urgent technical problem;
 when it is not necessary to supply treated water to the
house/application (refill swimming pool, irrigation,...).

RESIN CLEANER
Other contaminants (f.e. iron) present in the feed water can
cause the resin bed to foul up, resulting in a loss of softening
capacity. An approved resin cleaner can be used periodically
to thoroughly clean the resin bed.

SANITIZING THE WATER SOFTENER
WITH 3-VALVE BYPASS SYSTEM (not included)
This water softener is manufactured from premium quality
material and assembled in safe conditions to assure it is clean
and sanitary. If installed and serviced correctly, this water
softener will not infect or contaminate your water supply.
However, as in any 'device' plumbed-in in your water
distribution system, a proliferation of bacteria is possible,
especially in case of 'stagnant water'. Therefore this water
softener is equipped with a 'days override' feature, that will
automatically rinse the resin bed periodically, even in case of
low or absence of water usage.
