1 - INTRODUCTION
Osmosis is a natural phenomenon for which a solution poor in mineral salts passes
through a semi-permeable membrane then it is diluted in another one that has a greater
saline concentration.
By counter pressure, this procedure is inverted and you obtain REVERSE OSMOSIS:
in fact, by pushing a solution with a high concentration of mineral salts against a special
membrane, PROCESSED WATER is obtained. Due to its structure and properties, the
membrane almost completely retains dissolved salts, heavy metals, pollutant elements,
bacteria and viruses letting the water pass in all its genuine purity.
REVERSE OSMOSIS is therefore the safest and most widespread purication system
around the world; the advantages, other than the basic reliability of the system, are:
simple assembly, very low operating costs and the total absence of chemical products.
The DP model can eliminate from water all impurities and harmful pollutants. Treated
water is the ideal solution for household use and delivery since the exclusive ltration
system forms a safety barrier against different pollutants in groundwater.

6 - INSTALLATION
Installation and maintenance should be carried out to standard by specialist
technicians, in particular in compliance with this manual, pursuant to Ministerial
Decree no. 25 of 7 February 2012 and, where relevant, with provisions in Ministerial
Decree no. 37 of 22 January 2008.
The reverse osmosis purifying system was designed for installation in a closed envi-
ronment, not outdoors, in a hygienically suitable location, protected from frost. It must
also be connected to standard to the electricity mains and the drinking water mains, in
compliance with the technical characteristics outlined in chapter 2.
• For a perfect preservation, the membranes are kept in preservative substances.
Therefore, do not use the rst water produced by a new system, or on which the
osmotic membrane was replaced, but let it ow for 2 cycles of approx. 10 minutes,
with 5-minute stop intervals.
• Always install a sediment pre-lter with an adequate ow rate and characteristics
based on the system and the quality of the input water.
• Installations, repairs, interventions or changes must be carried out by authorised staff.
• The SLIM models require non-optional FC500 ltration.
Before proceeding with the installation, check if there is enough space to:
• Comfortably install the water connections;
• Easily remove spare parts;
• Carry out maintenance.
Water connection:
Install the water connections following the writings on the machine, ”IN” means water input; ”OUT”
means water subjected to reverse osmosis, for delivery;
”DRAIN” means water output for drainage.
Supply the machine with an adequate tubing based on the water system to be created.
Always install a shut-off valve (for example a lever tap), upstream of the water supply circuit.
To check if the ow rate of the supply circuit is adequate, proceed as follows:
Install a gauge IMMEDIATELY BEFORE THE MACHINE INLET. The system pressure
during operation in the delivery phase must be at least 0.5 bar.
Electricity connection:
Check if the fuse is in the power supply socket of the machine. Check the characteristics
and safety requirements of the electrical system.
Position the switch on 0 (machine off) and connect the machine to the electrical system
with the specic cable.

- 12 -
Start-up:
Having connected the water system:
• Open the water supply slowly, making sure there is no leakage.
• Press the start button
• Open the tap and let water ow to bleed the air.
ATTENTION: Do not operate the machine without having opened the water supply rst.
The pump can get damaged if run dry.
After operation, sanitise the system.
Carefully ll in the installation certicate and the maintenance table and affix the serial
number sticker from the sanitising agent packaging on the cap. Everything must be kept
with the system. Alternatively, preserve and manage data and records of intervention
using the RO-Check app. If the documentation is not lled in properly, the manufacturer
cannot be held in any way liable for the quality of the water treated and for the integrity
of the system.
Check and, as necessary, adjust pressure and xed residue (see dedicated section).
Pump adjustment
The vessel is equipped with a pressure adjustment system. In the pressure testing pha-
se it is adjusted to 8 bar. The pressure can vary based on the actual conditions at the
installation site or based on system wear. After installation and during the maintenance
phase, check and adjust the pressure if necessary.
Permitted values:
Minimum 6.5 bar
Optimal 8 bar
Maximum 9 bar
Procedure
Activate the system and check the pump pressure.
If calibration is necessary, proceed as follows:
• Unscrew the adjustment device to minimum pressure
• Screw in the adjustment device to slightly exceed the calibration pressure
• Work on the adjustment device to reach the calibration pressure
Mixer adjustment
The pump is equipped with a bypass system to adjust the xed residue of the produced
water; the bypass is completely tightened in the test phase. After
installation and in the maintenance phase, check and adjust the
bypass if necessary.
The xed residue can be estimated with the TDS meter or con-
ductivity meter. Use the bypass system knob until you reach the
desired value.
Fixed residue that is too low could influence the pH. After
adjustment, measure the pH, checking it has returned within the potability values.

7 - SPARE PARTS AND PRE-FILTRATION
The machine requires carbon lter pre-ltration, which is not an optional, use only
materials supplied or approved by the manufacturer . Not installing pre-ltration or use
of unapproved components will cancel the warranty.
Approved pre-ltration:
FC500 FC500 Puro
For maintenance, use only spare parts supplied or approved by the manufacturer .

Basic operation
The systems of the DP series deliver water with an automatic osmosis management.
Water delivery is controlled by a maximum pressure switch inside the machine. When the
water demand ceases (for example, when the tap is closed on the permeate pipe), the
pressure rises up to the tripping value of the pressure switch (2.5 bar), and the control unit
will stop water delivery.
When there is a water demand (for example, when the tap is opened on the permeate
pipe), the pressure drops and the pressure switch will send a command for water delivery
to the control unit.
See the ELECTRONICS MANAGEMENT chapter for further details.
Emergency bypass
The versions with bypass function integrate a system which, if the system is locked, re-routes
the entire input water directly to the output by opening the solenoid valve. Doing so, even
if not treated, water can be delivered while waiting for technical support.
To pass from standard mode (osmosis) to emergency mode (bypass), activate the diverter
valve (8) bringing it to the bypass position.
NOTE:The bypass circuit is also protected by the fuse. If the system does not supply water
even after the bypass function is enabled, the fuse may need to be replaced.
Anti-ooding
The machine is equipped with an anti-ooding system, which can detect leaks in the
machine and will immediately stop water delivery. The system cannot detect and block
ooding from leaks outside the machine. If necessary, install management and control
devices for external ooding.
The manufacturer cannot be held liable for any ood damage caused by leaking compo-
nents outside the machine.
