It is essential for the product to work correctly to use original spare parts or accessories. The
manufacturer is relieved of all responsibility for any failures due to tampering or the use of non-compliant
spare parts and accessories
The ambient temperature of use must not exceed 50 ° C.
The product must be used on the cold water circuit. It is advisable to treat water with a temperature not
exceeding 25 ° C to avoid abnormal reactions of the polyphosphate salt.
The manufacturer declines all responsibility for any intervention carried out on the equipment by
unqualified personnel.
2. USE
The water commonly distributed in cold water systems contains calcium and magnesium salts which determine
its hardness.
Cold water, once heated, favors a chemical reaction and the subsequent precipitation of magnesium and
calcium carbonate, as well as carbon dioxide. Carbon dioxide favors the corrosion of pipes while calcium
carbonate precipitates deposits of limestone.
Without actually removing the limestone, through the use of the proportional dosers of AQUACAL
polyphosphate salt an adequate anti-scale and anti-corrosion treatment of the water is guaranteed,
guaranteeing a longer life for the pipes, the exchangers, the tanks, etc.
It is mainly used upstream of water systems, boilers, heat exchangers, boilers and washing machines,
ensuring compact dimensions, simple and rapid installation, low product consumption and low maintenance
costs.
The installation of the polyphosphate feeder (or other food-grade chemical conditioning) is foreseen by the UNI-
CTI 8065/89 in articles 6.4.1-6.4.3 and implemented by Italian DPR 59/2009 in art. 4 paragraph 14.
This appliance complies with the following standards:
Plastic material container:
• Italian DM 174 of 06 April 2004 - Concerning the materials and objects that can be used in fixed collection,
treatment, adduction and distribution systems for water intended for human consumption.
• Italian DM 25 of 7 February 2012 - Technical provisions concerning equipment for the treatment of water
intended for human consumption.
Polyphosphate salt:
• UNI EN 1210: 2005 standard - Chemicals used for the treatment of water intended for human consumption.
• Product not subject to the CE marking pursuant to Legislative Decree n. 52 of 02/03/97 and n. 285 of 16/07/98.
• Product classified as non-hazardous pursuant to Legislative Decree 03/14/2003 n. 65 (Directive 1999/45 /
EC) and related Regulation n. 1272/2008 (CLP).

3. HYDRAULIC CONNECTION
It is advisable to connect the AQUACAL dispenser to the water system by inserting a special by-pass, in order
to allow the operations of replenishing the polyphosphate salt inside the vessel.
By using the AQUACAL–R dispenser, on the other hand, it is not necessary to carry out the by-pass since the
reintegration of polyphosphate salt can be carried out simply by positioning the black levers horizontally. The
same, in fact, have by-pass functionality.
All models can be mounted both in systems with vertical and horizontal pipes, changing the orientation of the
connection nipple.
To change the orientation of the nipple follow the instructions below:
1) Unscrew the connecting screws.
2) Rotate the nipple 180 °.
3) Screw the connection screws, being careful not to pinch or damage the sealing O-rings.

4. MAINTENANCE
The AQUACAL can be used in water whose temperature does not exceed 50 ° C.
When the bellows inside the jar is completely relaxed it is necessary to replenish the polyphosphate by
performing the following operations:
AQUACAL
1) open the tap A - FIG.A
2) close the BC taps - FIG.A
3) depressurize the vessel using the vent screw
4) unscrew the jar - FIG. C
5) replenish the polyphosphate
6) contract the bellows
7) screw the jar paying attention to the correct O-Ring positioning. - FIG. E
8) tighten the vent screw - FIG. C
9) open the taps BC - FIG. A
10) close the tap A - FIG. A

5. SALT INTEGRATION
In the AQUACAL is possible to use dissolved polyphosphate salt or tablets.
If using powdered dissolved polyphosphate salt, follow the steps below:
a. After closing the by-pass, remove the jar from the dispenser, wash it and rinse it to remove any impurities;
b. Pour the powdered salt into the jar, taking care to fill it about halfway.
c. Pour 20cc of water into the jar.
d. Mix a little to mix water and dust.
e. Let it rest for about 30 minutes, until the mixture solidifies.
f. Reassemble the vessel taking care not to damage the ORing.
g. Reopen the by-pass and let water flow in order to fill the jar. At the same time, let the air out of the jar.
If using polyphosphate salt dissolved in flakes follow the previous steps, without the need to add water and
without waiting for solidification.
If polyphosphate salt is used in tablets, follow the previous steps, introducing the tablet after having removed
at least the plastic cap, without the need to add water and without waiting for the solidification as the cartridge
is already solid.
The tablet is contained by a plastic casing with hood. When inserting the tablet in the dispenser it is always
necessary to remove at least the cap. If the casing is also removed, the tablet will dissolve faster as the water
touches a greater surface of salt.
6. CAUTIONS IN THE USE OF SALT
The polyphosphate salt does not eliminate limestone.
It acts by creating a film that protects the pipes, the exchangers and the tanks from the gripping action of the
limestone which therefore does not cling to the surfaces and flows with the water coming out of the taps.
It is therefore normal that the water coming out of a polyphosphate salts dispenser seems a little "gelatinous".
This is precisely its peculiarity.
For this reason, equipment with polyphosphate salt must be applied on flowing water circuits.
The stagnant water, in fact, or the excess temperature of the treated water can lead to dissolve
more substance than necessary, which accumulates (in the absence of water flow) in the doser
vessel, which can appear as in the image in side.
In these cases it is necessary to empty the jar from its contents and replace the salt or wash it
thoroughly so that all the gelatinous fluid is expelled, otherwise, when the water circuit is
reactivated, the excess gelatine could obstruct nozzles or exchangers, making maintenance
operations necessary. .
Keep the spare polyphosphate salt away from moisture.
If the salt absorbs moisture when it is first used, it will emit gelatinous substance in an amount higher than
normal, even if over time it will tend to stabilize.
If this happens, make sure the system has running water.
