5 Water purification process description
Purification phase Remarks
5.1 Pretreatment
Removes:
- Particles of size equal to or above 5 µ.
- 99.99% of hypochlorite.
- Most of the organic material present in the feed water.
On equipment installed in areas where the feed water has high
amounts of suspended solids, turbidity or colloids, it may be
necessary to include additional prefilters to reduce significantly the
presence of substances that may affect the equipment's
performance.
In very hard water it is necessary to install a water softener before
feeding the equipment.
Cartridge 1 and 2
5.2 Reverse osmosis
Removes:
> 99.95 % of organic matter (greater than 150 Dalton) present in
the water and 95 - 98% of the Total Dissolved Solids (TDS).
The RO membrane must operate at pressure of 4 - 6 bar
for optimum performance. There should be a minimum
inlet pressure of 2.5 bar.
In facilities with high inlet pressure (> 6 bar) it is necessary
to install a pressure regulator before the water inlet to the
equipment.
5.3 Deionisation
The permeate passes through a mixed bed of strong cation/anion
resins, retaining all the anions and cations still present in the water
and which have not been removed in the RO process.
The result is a Type II Analytic Grade Water with a conductivity of
less than 0.2 µS/cm (Resistivity > 5 MΩ.cm) newly produced.

If a reservoir is not supplied together with the equipment, it is supplied a level to be placed on a reservoir selected by the
user.
It is necessary to make a holes (∅16 mm) to place the fittings for the level and the Type II Water tube.
The level should be placed in vertical position.

7.2 Hydraulic connections
Flexible tube and tube cutter are supplied with the equipment to carry out hydraulic connections.
Quick connections:
The hydraulic connections are made by means of a System known as Quick Connection (QC): Simply insert the
tube until it stops, and it is connected.
To disconnect the tube, first press the central washer of the QC device inwards while pulling the tube in the
opposite direction.
Important: Tubes connected with Quick Connection must have a clean cut, perpendicular to the length of the
tube. The tube section inserted in the connection will be smooth, with no abrasions. Any bevel cut-out or a
damaged tube termination will make the connection imperfect and lead to water leakage.
a. Water inlet: The water inlet will be provided with a stopcock with BSP male threads of 1/2". Thread the connection piece
supplied.
Do not use Teflon for this connection (the connection is fitted with a rubber seal).
If due to highly polluted inlet water it is necessary to install and additional pretreatment, the connection
sequence will be:
Feed water - Enters additional pretreatment - Exits pretreatment - Enters the equipment. All connections are
quick type.
b. Drainage: The drainage point will be at a maximum 3 m far. The Rejection tube must be positioned to
ensure that it cannot move from its position by a flange or by inserting it approximately 30 cm into the drain pipe.
The Rejection tube is connected with a quick connection "Rejection" located at the rear of the equipment.
Using the drain flange:
Drill a 6.5 mm hole in the drain pipe where the Rejection tube is to be inserted.
Place the pad over the hole and the drain flange on top, gripping the pipe. Secure it by tightening the screws on both sides.
Insert the Rejection tube 5 cm, through the flange.
Secure the Rejection tube with the drain flange nut.
c. Tank level: The tank level is connected at the rear fitting "0"

Connect the Micromatic with the Level connector using a wire supplied with the equipment.
d. Water Type II: Connect a tube at the rear fitting 2 with the fitting placed on the cap of the tank.
7.3 Equipment start-up

The user can select a different set value (between 1 and 20 µS/cm) to activate this warning.
8.3.2 Water temperature
The conductivity values displayed on the screen are compensated at 25°C.
The conductivity value depends on the water temperature and is usually expressed by normalising the reading to 25°C. To this
end, the water temperature at which measurement is performed must be taken into account and a correction factor of 2% applied
for each degree of temperature deviation from the reference temperature:

C
25
= Conductivity at 25ºC (µS/cm)
C
t
= Conductivity at temperature t (µS/cm)
t = temperature at which measurement is performed (°C)
By default the equipment is delivered with a temperature value of 25ºC.

11. Troubleshooting Guide
As a general prevention measure, we recommend carrying out the maintenance of the elements
when the warning to replace the cartridges is displayed.
Nevertheless, unforeseen situations could turn up requiring intervention in the equipment. The
following guidelines attempt to compile most of these situations and the best corrective action.
Trouble Action
The screen does not light or the menu does not work
Unplug the equipment. Disconnect the Plug-in.
Connect first the plug-in and then plug the equipment into the
power system.
If the fault continuous, check the electrical connection:
Connection to the power system, transformer, electronic card
The equipment does not produce water or water production
flow is very low
Check that the water supply is not turned off.
Check the inlet pressure: The lower it is, the lower the
performance of the equipment.
Release the pretreatment cartridges and check the degree of
fouling: If they are very dirty, the silting blocks the flow of water.
Check that the stopcock to the tank is Open.
Check that the tube connecting the equipment and the tank is
not trapped or accidentally pinched.
If the above checks do not indicate deviations, the lower
production may be due to RO membrane depletion.
The conductivity of the water produced is high
Possible depletion of the resin: Replace the cartridges
Check that water flows through the rejection tube
The tank's filling level is inadequate Level positioning is incorrect
Check the level connections
The deionisation resin lasts for short time
Possible depletion of the RO membrane
The equipment loses water
Failure in some of the equipment's connection. Or leak in the
pump
Consult Technical Assistance Service
After replacing the pretreatment, the warning message did
not deactivate
Reset the hour meter to 0 (see 8.3.3)
