2. Safety Information
The security information included in this chapter should be read carefully.
The user should check for compliance with security conditions set out in this Manual to ensure the safe use of the equipment.
In case of doubt, contact the Technical Assistance Service.
Safety information is related to both user protection and equipment protection.
Access to the equipment interior
Only authorised technical service may access the equipment interior to carry out maintenance and repair tasks other than the
routine replacement of expendable items.
Electrical connections
- Check that connection to the power system is 110 - 230 VAC, 50 -60 Hz.
- Only use the transformer supplied with the equipment. Plug Type C, Europlug.
- Supply voltage fluctuations should not exceed 10% of the rated voltage.
- Supported transitional overvoltage: The typical present in the power supply network (category II of the standard IEC
60634-4-443).
- The electrical plug should not be situated below the equipment.
- The electrical plug should be accessible in case of be necessary to disconnect the equipment quickly.
Explosive atmospheres
The equipment is not designed to work in explosive atmospheres.
Environmental pollution permitted
Pollution grade 1 (No environmental pollution or only dry pollution, not conductive).
Feed water and hydraulic connections
The feed water must comply with the specifications listed in this Manual.
Feeding poor quality water (turbidity and/or high hardness, inadequate conductivity, unwanted pollutants, etc.) can result in
deterioration of the equipment components or a lower performance.
Respect the pressure conditions established for the feed water to the equipment. High pressure can damage the hydraulic system.
In these cases, it is necessary to install a pressure regulator before the equipment.
A feed water pressure lower than the minimum required will cause poorer performance and improper functioning of some of the
system components.
Have a stopcock that is easily accessible when you need to cut the water supply to the equipment.
Locate the equipment so that the electric and hydraulic connections located on the rear of the equipment are not
adversely affected.
Prevent straining the power cable or hydraulic connections.
Consumables
Replace the consumables items in the times anticipated and based on the messages from your equipment.
Use only original expendable items. Using non original components may cause equipment damage and loss of guarantee.
To move the equipment, handle it by holding at the base.

3. Equipment use and specifications
Micromatic water purification equipment provides Type II purified water (ASMT) from the tap water.
The equipment combines several processes to supply purified water (pre-filtration, reverse osmosis and deionisation).
The water provided by the equipment is suitable for numerous laboratory techniques, preparation of culture media and other
applications requiring Type II purified water.
Once the equipment has been connected and started up, operation is automatic.
The purified water of the Micromatic equipment is not fit for human consumption.
3.1 Electrical Power Requirements:
110 - 230V AC / 50 - 60 Hz Single-phase / 36W.
Use only the transformer supplied with the equipment.
The power point should not be situated below the equipment.

If the equipment may be submitted to low temperatures, make sure it is no less than 5°C.
Relative humidity HR = No condensation. HR < 80% for Temp. up to 31°C (linear decrease up to 50% at 40°C).

3.2 Equipment location
The equipment is designed for indoor use and < 3000 m altitude.
The location of the equipment must not obstruct the access to the electric connection.
Make sure that the rear connections of the equipment are not adversely affected by an inappropriate location.
An easily accessible stopcock must be installed between the tapping point and the equipment inlet in case the water supply
must be cut.
The equipment needs a drainage to collect the rejection water.
3.3 Equipment features:
Production flow *: 2.5 l/h *
Operating pressure: 2.5 - 6 bar
Conductivity
(compensated at 25°C) < 0.2 µS/cm

4.6 Type II Water Tank
The equipment produces Type II water that is collected in a
storage tank that can be supplied with the equipment (optional).
When the equipment is supplied with a Tank, the level is placed
on the tanks.
If not, it is supplied a level detector to be incorporated into the
tank for automatic operation of the system.

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.
Cartridge 3 and 4

5.4 Type II Water Storage
Type II Water is stored in an open tank, ready for use.
A level detector must be connected to the tank to work in automatic
mode.
Rear connections:
- [0] Tank level
- [1] Rejection
- [2] Tank
- [3] Feed water
5.5 Automatic operation of the equipment
The equipment has the following operating modes:
- Production: The equipment produces Type II Water that is sent to the storage tank. When the tank is full,
the equipment stops automatically.
- Standby: The equipment does not produce water because the tank is full.
- Water dispensation: The user obtains Type II Water taking it directly from the storage tank
