2.3. Hazards
All the safety and protection instructions contained in this document must be observed in order to
avoid temporary or permanent injury, damage to property or environmental pollution.
At the same time, any other legal regulations, accident prevention and environmental protection
measures, as well as any recognized technical regulations relating to appropriate and risk-free
methods of working which apply in the country and place of use of the device must be adhered to.
Any non-observation of the safety and protection rules, as well as any existing legal and technical
regulations, will result in a risk of temporary or permanent injury, damage to property or
environmental pollution.
2.3.1. Personnel
Caution
Only qualified and professional personnel, based on their training, experience and
instruction as well as their knowledge of the regulations, the safety rules and operations
performed, are authorized to carry out necessary work.
2.3.2. Material
The following points must be observed to ensure proper operation of the system and the safety of
user:
• be careful of high voltages present on the transformer (100 - 240 V);
• do not put your fingers in the system (risk of injuries with moving parts and shock due to electric
voltage).
2.4. Hygiene and sanitization
2.4.1. Sanitary issues
Preliminary checks and storage
• Check the integrity of the packaging. Check that there is no damage and no signs of contact with
liquid to make sure that no external contamination occurred;
• the packaging has a protective function and must be removed just before installation. For
transportation and storage appropriate measures should be adopted to prevent the
contamination of materials or objects themselves.

Assembly
• Assemble only with components which are in accordance with drinking water standards;
• after installation and before use, perform one or more manual regenerations in order to clean
the media bed. During such operations, do not use the water for human consumption. Perform a
disinfection of the system in the case of installations for treatment of drinking water for human
use.
Note
This operation must be repeated in the case of ordinary and extraordinary maintenance. It
should also be repeated whenever the system remains idle for a significant time.
2.4.2. Hygiene measures
Disinfection
• The materials used for the construction of our products meet the standards for use with potable
water; the manufacturing processes are also geared to preserving these criteria. However, the
process of production, distribution, assembly and installation, may create conditions of bacterial
proliferation, which may lead to odor problems and water contamination;
• it is therefore strongly recommended to sanitize the products. See 7.2. Sanitization, page 96;
• maximum cleanliness is recommended during the assembly and installation;
• for disinfection, use Sodium or Calcium Hypochlorite and perform a manual regeneration.

3.1.1. Performance flow rate characteristics
The graph shows the pressure drop created by the valve itself at different flow rates. It allows to
predetermine the maximum flow rate going through the valve depending on the system settings (inlet
pressure etc). It also allows to determine the valve pressure drop at a given flow rate, and therefore
to evaluate the system pressure drop vs flow rate.

3.4. System regeneration cycle
Note
This valve allows to do down flow or up flow regenerations.
3.4.1. Downflow regeneration cycle (5-cycles operation)
Service — normal use
Untreated water is directed down through the resin bed and up through the riser tube. The hardness
ions attach themselves to the resin and are removed from the raw water being exchanged on the resin
beads against sodium ions. The water is conditioned as it passes through the resin bed.
Backwash — cycle C1
The flow of water is reversed by the valve and directed down through the riser tube and up through
the resin bed. During the backwash cycle, the bed is expanded and debris is flushed to the drain, while
the media bed is remixed.
Brine draw & slow rinse — cycle C2
The controller directs water through the brine injector and brine is drawn from the brine tank. The
brine is then directed down through the resin bed and up through the riser tube to the drain. The
hardness ions are replaced by sodium ions and are sent to the drain. The resin is regenerated during
the brine cycle. Afterwards the slow rinse phase starts.
Rapid rinse — cycle C3
The valve directs water down through the resin bed and up through the riser tube to the drain. Any
residual brine is rinsed from the resin bed, while the media bed is recompacted.
Brine tank refill — cycle C4
Water is directed to the brine tank, at a rate controlled by the refill controller [BLFC], to create brine
for the next regeneration. During brine refill, treated water is already available at the valve outlet.
Note
For illustration purpose only. Always verify inlet and outlet marking on the valve.
