2. General information
Water purification system “Labaqua” produces pure and ultrapure water that
complies with ISO 3696 Grade II and Grade I water requirements respectively.
Pure (ISO 3696 Grade II) water applications include, but are not limited to:
Feed for laboratory equipment (washing machines, clinical analysers, humidifiers,
autoclaves, hydrogen gas generators);
Manufacturing of chemical and biochemical reagents;
Buffer preparation;
Microbiological media preparation;
Sensitive analytical techniques (e.g. atomic absorption, ICP-OES).
Ultrapure (ISO 3696 Grade I) water applications include, but are not limited to:
High sensitivity analytical techniques (ICP-MS);
High performance liquid chromatography;
Molecular biology;
Cell culture.

6
There are two types of Labaqua water purification systems:
Labaqua HPLC –Ultrapure water system for analytical applications. Includes 25 l
water storage tank. Uses tap water as feed water, often referred to
as “tap water system”.
Labaqua Bio –Ultrapure water system for molecular biology and cell culture
applications. Includes 25 l water storage tank. Uses tap water as
feed water, often referred to as “tap water system”.
Principle of operation
The hydraulic diagram of Labaqua water purification system is shown below.
The solenoid valve (Fig. 1/1) controls intake of feed water from the tap. The first
purification stage consists of the pre-filter set (P/N 10019, fig. 1/2 and 1/3) that includes
sediment filter and activated carbon intended to remove particles, free chlorine, organics
and colloids. A pressure switch (Fig. 1/5) controls feed water pressure. If feed water
pressure falls below 0.7 bar, the system will automatically switch on the boost pump (Fig.
1/4) and “LowPres” message will be shown on the display.
The boost pump (Fig. 1/4) is used to maintain pressure at the level necessary for
the efficient operation of the reverse osmosis membrane (only in the tap water systems,
Fig. 1/9), deionization module (P/N 10310, fig. 1/12), and UV sterilization module (if
installed, P/N 10102, fig. 1/16).
From the boost pump, the feed flow goes to the membrane to be split into two parts:
the permeate, diffused through the membrane, and the concentrate, which passes over the
membrane, carrying away contaminants to the drain. The permeate goes to the third
purification step –the IonPro deionization module (P/N 10310, fig. 1/12) where the
remaining ions are removed.
Before entering the tank, water is sterilized by UV lamp (if installed, P/N 10102, fig.
1/16); water quality is controlled by Grade 2 water conductivity sensor (Fig. 1/11). LCD
display provides information about the system status.
Purified water is stored in the tank and recirculated on periodical basis. Water in the
tank meets requirements of ISO 3696 Grade II.
Fig. 1. Principle of operation

Water dispensing
To dispense ISO 3696 Grade I water, press the Pump Grade I key. The pump (Fig.
1/15) is switched on and water flows through photooxidation module (P/N 10105, fig. 1/16),
polishing cartridge (P/N 10030, fig. 1/17) and protective sediment filter (Fig. 1/18). After
several seconds the valve (Fig. 1/21) opens and Grade I water is dispensed via the 0.22
μm point-of-use microfilter. Labaqua Bio system has an ultrafilter instead of the microfilter.
To dispense ISO 3696 Grade II water, press the Pump Grade II key. Grade II
dispense pump is switched on, and water is dispensed via the “Out” port of the tank.
Possible Labaqua modifications
Labaqua HPLC: Ultrapure, equipped with photooxidation module for low TOC.
Labaqua Bio: Ultrapure, equipped with UV sterilization module, ultrafilter and photooxidation
module for low TOC.

3.3. Pre-installation requirements
The Labaqua system can be placed on a bench or attached to a wall. If the system
is placed on the bench, allow space on the bench 500x500mm. Allow enough space
for the tank (DMH 400x400x600mm) under the bench.
Electrical connections: 230 V, 3A.
Feed water should be filtered with 5 μm sediment filter (not included).
Feed water should be filtered with at least one 5 μm sediment filter. If the filter is
not installed, the input strainer may become clogged thus blocking the water
flow, or pre-filter life can be reduced.
Sediment filter for tap water line is usually available from a local plumbing shop. If
necessary, the sediment filter set (that consists of 5 um sediment filter and 1 um
sediment filter) can be obtained (example below). The part number is 10168.
Attention! In case of Labaqua system pre-filter set (P/N 10019) pre-mature
clogging, we ship the new pre-filter under warranty only if we get a
photo of the sediment filter installed in the tap water line.
Feed water hardness does not affect produced water quality. However, operation of
the system with hard fed water may result in premature clogging of reverse osmosis
membranes and reduced Grade 2 water flow. Therefore, it is strongly
recommended to install a water softener or polyphosphate filter if water
hardness is above 160 ppm.
Drain level should be lower than Overflow port of the tank. Drain is required. The
water purification system is equipped with Ø1/4’’ drain pipe. Overflow port pipe is
Ø3/8’’.
Feed water outlet for Labaqua system connection has to be ½’’ or ¾’’ male thread.
A feed water outlet with ½’’ female thread is acceptable although not
recommended. The system is equipped with feed water tube (1/4’’ OD) and
adapters for ½’’ threaded outlets (male and female thread) as well as for ¾’’
threaded outlet (male thread). The feed water tube should be connected to the ¼’’
JohnGuest fitting of the adapter. Feed water outlet should be equipped with a valve
for shutting off water supply.

3.4. Setting up
3.4.1. Install the controller module and connect the cable (Fig. 2/1).
3.4.2. Carefully attach the controller module to the holder at the top right of the system
(Fig. 2/2)
3.4.3. While the system is disconnected from mains, it is recommended to carefully
remove the rear panel and check for any transportation damage. Reinstall the panel
before connecting the power cable to 230V AC power supply socket.
3.4.4. Fix the controller module with two screws on the lower side of the module.
3.4.5. Unpack the microfilter/ultrafilter and screw it into the threaded outlet under the
controller module holder (Fig. 2/3). Before connecting, make sure that the sealing
O-ring is inside the holder.
3.4.6. Connect the feed water to the Ø1/4’’ John Guest inlet marked Tap Water. Use an
appropriate adapter from tap water to Ø1/4’’ tube, see p. 3.2. Tap water should be
filtered with 5-micron mechanical filter (not included).
3.4.7. Connect Ø1/4’’ JG connector marked Drain to the drain using Ø1/4’’ plastic tube.
Note: Unscrew the cap of the purified water storage tank and remove the
packing material inside.
3.4.8. Connect Ø1/4’’ John Guest outlet “OUT”to the inlet “In”of the tank.
3.4.9. Connect Ø1/4’’ John Guest outlet “Rec Out”to the inlet “Rec In”of the tank.
3.4.10.Connect Ø1/4’’ John Guest outlet “Rec In”to the inlet “Rec Out”of the tank.
3.4.11.Connect the tank cable to the TANK connector.
Note: If nothing is connected to the TANK connector, the system will show
“TnkFull”.
3.4.12.Connect the power cable. Make sure the system is properly grounded.
3.4.13.Connect approximately 1 m of Ø3/8’’ tube to the tank Out connector to ensure
convenient Grade II water dispensing. The end of the tube should be free and must
not be connected to anything. The backpressure will damage the pump.
3.4.14.Connect the Overflow connector of the tank to the drain with Ø3/8’’ tube.
Fig. 2. Setting up
3.5. Feed water and drain requirements
3.5.1. Feed water should be filtered with 5 μm sediment filter. If the filter is not installed,
the input strainer may become clogged and block the water flow. Life of pre-filters
can be reduced too.
3.5.2. Feed water connector port can be Ø1/2’’ (male or female) or Ø3/4’’ NPTF (male)
thread. The system is equipped with adapters for both water supply connectors.
The feed water tube should be connected to the Ø1/4’’ JG port of the adapter.

11
3.5.3. Tap water pressure should be above 0.7 bar.
3.5.4. Drain pipe should be lower that the level of the instrument and the level of the
Overflow connector of the tank. The water purification system has Ø1/4’’ OD drain
pipe. The Overflow connector of the tank is for Ø3/8’’ OD pipe.
3.5.5. Feed water supply connector and drain should be within 3 meters from the
installation site.
3.6. Deionization and Polishing module installation.
3.6.1. Push the stems in the ¼’’ elbows with ¼’’ tubes into the John Guest fittings of the
Deionization and Polishing modules.
3.6.2. Install the deionization and polishing modules. The positions of the modules are
marked with labels “IonPro deionization module” and “Polishing module”. Each
module has now John Guest elbows and short tubes installed. Open the front door.
Place a module at the labelled site; push the tubes into John Guest fittings at the
inner wall. Then attach the module fully to the inner wall by putting the latch at the
bottom of the module into slot on the wall.
3.6.3. Screw the pre-filters into the grey filter heads.
4. Rinsing the system
Note: The pre-filter should be rinsed prior operation and each time new
filter is installed. Failure to do so can lead to reduced life of the
reverse osmosis membrane.
Rinse the system according to the following procedure:
4.1. Open the front door. Disconnect the pre-filter outlet tube (right behind the prefilter
heads) from the John Guest fitting (see pictures below). Put a beaker under the
tube.
4.2. Switch on the unit. The display is switched on and “STANDBY” message is shown.
4.3. Open the tap water supply.
4.4. Press and hold the Run key (Fig. 4/8) for 2 seconds and collect approximately 1
litre of water and press the Run key to stop the water flow. The pre-filter is rinsed.
Note: If “TnkFull” message is shown then probably the tank plug is not
connected.

12
4.5. Reconnect the outlet tube to the outlet John Guest elbow.
4.6. Press Run key and wait until storage tank is filled with water.
4.7. Put the end of 3/8’’ tank “Out” tube into a sink, press “Pump Grade 2” and dispense
water from the tank.
4.8. Let the system fill the tank again. As the tank is full, ask the customer to leave the
system overnight (shut off tap water supply for safety reasons). The system will
recirculate water in the tank and get rid of organic compounds as well as rinse the
polishing module.
4.9. The microfilter (or ultrafilter) should be rinsed prior to use! Ask the customer to
press “Pump Grade 1” next morning and dispense water in the tank through point-
of-use filter (microfilter on Labaqua HPLC or ultrafilter on Labaqua Bio). The
microfilter (or ultrafilter) needs to be rinsed with at least 20 litres of purified water.

- indication of current water grade (superscript) and water conductivity (precise
readings of water quality are shown when the system is in Running, Grade I
dispense or Recirculation mode);
- water temperature and filter life counter.
5.3. If the system is equipped with TOC (total organic carbon) level monitoring module,
display shows TOC reading (e. g. <2 ppb). TOC level reading will be shown only
after the storage tank is at least partially filled with water and recirculation stage has
started.
5.4. The purified water quality is controlled by two sensors. First sensor (Fig. 1/11)
measures and displays conductivity of Grade II water, flowing into or recirculating in
the storage tank. Second sensor (Fig. 1/19) measures and displays conductivity of
Grade I water that is dispensed at the moment.
5.5. Indication in superscript next to the conductivity can take values “1” or “2”, showing
current water grade.
5.6. To fill the tank with purified water, press and hold the Run key (Fig. 4/8) for 2
seconds. If tank is neither full nor disconnected and the feed water pressure is
enough, the display shows “Running”. Now the Labaqua system is filling the tank
with Grade II water. As soon as the tank is full, the system shuts down the water
supply and shows the “TnkFull” message.
5.7. To dispense Grade I water, press Pump Grade I key (Fig. 4/6). After five to ten
seconds, Grade I water is dispensed through the 0.22 μm filter. If ultrafilter is
installed, loosen the degassing valve to get rid of air. Press the Pump Grade I key
again to stop water dispensing.
5.8. To dispense Grade II water from the tank, press the Pump Grade II key (Fig. 4/7).
To stop dispensing, press the Pump Grade II key again.
5.9. System will circulate water on periodical basis to prevent growth of microorganisms
in the tank. During recirculation phase, the reading of Grade II water is shown on
the display. For the systems with TOC monitoring module, display shows TOC
reading in ppb. TOC reading appears in the left bottom display when purified water
storage tank is full and recirculation stage starts.
5.10. Recirculation is switched off when the system is in the Standby mode. To prolong
life of polishing module, please set the system to the Standby mode if it is not used
for long time (e.g. for the night).
5.11. Press Run key to toggle Standby mode on and off.
5.12. If feed water pressure falls, the display indicates “LowPres”.
Note: To actuate a key, press and hold it for two seconds.

14
Note: If the system is newly installed or has not been used for a long time,
it recommended to leave it in the Recirculating mode for several
hours before usage. It will allow the system to fill the tank and
recirculate water to reduce TOC content.

counter when changing filters, and “Options” submenu:
- switch between MΩ*cm and μS/sm conductivity units;
- set recirculation period (time between recirculation cycles);
- set recirculation cycle duration time;
6. TOC level reduction and monitoring
Total organic carbon (TOC) describes level of organic contaminants in pure water.
High concentration of organic contaminants may affect results of several analytical
methods, e.g. high performance liquid chromatography. Therefore, for some applications
TOC level should be controlled and kept minimal.
Grade II water coming to the storage tank generally has low TOC level if proper
deionization resins are used. However, TOC level may rise during storage, therefore water
recirculation through photooxidation module and polishing cartridge is necessary to keep
TOC level low.
Unfortunately, organic contaminants may not have effect on conductivity of water,
so conductivity sensors cannot be used for TOC level monitoring. A special TOC level
monitoring module is needed to measure TOC level. The monitoring module consists of a
TOC photooxidation module, valve and a conductivity sensor.

15
TOC monitoring module (optional) operation principle
During recirculation stage a water sample is introduced into the TOC photooxidation
module where it is oxidized for several minutes. During this phase, water conductivity rises
because of the oxidation of organic molecules. The rise of conductivity is proportional to
TOC level of water.
After the oxidation phase is finished, water is released from the TOC photooxidation
module and its conductivity is measured by the conductivity sensor. TOC level is calculated
from the rise of conductivity.
Note: As TOC level measurement is made during the recirculation stage,
the TOC level value is shown on the display only with storage tank
partially filled with water and during recirculation.
