2. HEALTH AND SAFETY NOTES
CENTRA products have been designed to be intrinsically safe,
however, it is important that personnel working on these units
understand any potential dangers. All safety information detailed in
this handbook is highlighted as WARNING and CAUTION
instructions. These are used as follows:
WARNING! WARNINGS ARE GIVEN WHERE FAILING
TO OBSERVE THE INSTRUCTION COULD
RESULT IN INJURY OR DEATH TO
PERSONS.
CAUTION!
Cautions are given where failure to
observe the instruction could result in
damage to the equipment, associated
equipment and processes.
WARNING! IF THE EQUIPMENT IS
USED IN A
MANNER NOT SPECIFIED BY ELGA, T
HE
PROTECTION PROVIDED
BY THE
EQUIPMENT MAY BE IMPAIRED.
POSITION THE POWER S
UPPLY SO
THAT IT CANNOT COME
INTO CONTACT
WITH WATER
2.1 Electricity
It is essential that the electrical supply to the CENTRA is isolated
before any items are changed or maintenance work performed.
The external isolator providing power to the unit should be
positioned so that it is easily accessible by all users.
WARNING! THIS APPLIANCE MUST BE EARTHED
2.2 Pressure
The main water supply should be isolated and residual pressure
released prior to removal of any components or carrying out work
on the unit.
Switch off the process and relieve pressure in the distribution loop
by opening a point-of-use.
2.3 Sanitization Chemicals
During the sanitization cycle Minncare Cold Sterilant is used and
relevant safety guidance is included in this handbook. Please refer
to the manufacturer for material safety data sheets.
Minncare Cold Sterilant is EPA registered as a sterilant, high level
disinfectant, and sanitizer.
Spent Minncare Cold Sterilant is acidic and requires normal
neutralization as specified by your local state and local regulations.
1% of Minncare Cold Sterilant has a pH of 3.5.

3. PRODUCT AND PROCESS
DESCRIPTION
3.1 Product Description
The CENTRA range of water purification units has been
specifically designed to produce, distribute and maintain purified
water for laboratory, medical and industrial applications.
Purified water may be distributed around the installation under
pressure to single or multiple points of use.
A range of accessories is available to complement the unit (see
Section 12. - Consumables and Accessories, for detail).

3.2 Process Description
CENTRA - S200/R200 US
•Feed water enters through a control valve (V1), and
through a particulate filter (FH1) into the inlet of the RO
pump (P1). Pressure in the pipework of the pump inlet is
monitored with a pressure switch (PSW1) to ensure that
it cannot run without sufficient water.
•P1 provides sufficient pressure and flow to the RO
membrane (M1). The RO concentrate flow is controlled
through a pressure relief valve (PRV2) or concentrate
flush valve (V3).
•Upon initial start-up the system completes a concentrate
flush to remove scale and debris from the surface of the
membrane surface to ensure good RO performance is
maintained.
•RO permeate water passes through:
•Temperature sensor (TS1), which provides accurate
temperature measurement.
•Water quality sensor (QS1), which measures the
conductivity of the water.
•RO permeate water is initially flushed to drain through the
overflow device until one of the following conditions
occurs:
•Minimum flush time is completed.
•Water quality is below set alarm point.
•4 minutes permeate flush has occurred without the
permeate quality passing the alarm set point. This will
result in an alarm condition that may be cleared
automatically as the RO performance improves.
•Water enters the reservoir through permeate control
valve (V2) and fills the reservoir until full (350 liters). The
RO system will only function if the level in the reservoir is
sufficiently low, less than 240 liters.
•Upon reaching 350 liters the RO system performs a
further concentrate flush to reduce the concentrate
conductivity levels within the membrane housing and
reduce the possibilities of precipitation on the membrane
surface.
•Water from the reservoir is distributed around the
installation at pressure (6 bar maximum) by the
recirculation pump (P2), controlled via the pressure-
sustaining valve (PSV1) and monitored with a pressure
sensor (PS1), before finally returning through a spray ball
into the reservoir.
•Products fitted with a variable speed recirculation pump
(P2) use feedback from a pressure transducer (PT1) to
regulate the pump output to maintain a constant outlet
pressure (typically 4 bar). This also reduces the outlet
flow when water is not taken from the recirculation loop.

Page 6CENTRA - S200 US/CENTRA - R200 US Version 01 – 08/14
•Within the CENTRA – R200 US connections are
available to link to externally positioned cylinders
containing water purification media, to remove impurities
and maintain water purity around the system. The media
in the cylinders can be selected to meet specific
requirements.
WARNING: Any cylinders or additional equipment
installed (filters etc.) including ring-main
pipework, must be rated to the operating
pressure of the CENTRA system (6 bar
maximum).
•CENTRA - R200 US units include a UV chamber (UV1)
where purified water is exposed to intense UV radiation
to provide continuous bacterial control and to promote
the cleavage of organic molecules.
•Final filtering is provided by an absolute 0.2µm bacterial
and particulate filter. The difference in delta P between
PG1 and PG3 can be used to monitor the condition of the
filter.
•Finally the purified water passes through a:
•Temperature sensor (TS2), which provides accurate
temperature measurement.
•Water quality sensor (QS2), which measures the
resistivity of the water.
•Flow sensor (FS1) which electronically measures flow
around the system.
•Air is drawn into the reservoir when water level falls. To
maintain water purity, it is necessary to filter the air.
Water quality is maintained within the recirculation
system using a composite vent filter, which removes air-
borne contaminants such as volatile organic compounds
and carbon dioxide as well as air-borne particles and
bacteria.
•The CENTRA - S200/R200 US includes the ability to
drain the reservoir completely via V4 and sanitize the
installation semi-automatically via V8 to ensure that
bacterial levels within the installation are controlled.

Pipework and Pipework Installation
The precise details of each installation will vary according
to the individual customer requirements.
Note: Refer to Typical installation and layout diagram
(Section 4.3 - fig. 1 and fig. 2).
If existing pipework installations are being utilized it is
recommended that Technical Support are contacted to
ensure suitability in terms of material and pressure drop,
and that correct installation and sanitization procedures
are adopted during system commissioning.
All connections to the unit are ¾"bspp female threads and
should be sealed with either PTFE tape or ‘o’ring fittings.
CAUTION!
The use of pipe sealant is not
recommended and may cause
degradation and failure of plastic
components.
All pipework should be suitable for the quality of water
being distributed and installed to manufacturer
guidelines.
CAUTION!
All pipework should have a pressure
rating exceeding the maximum
operating pressure of the installation
and suitably de-
rated for the maximum
water temperature.
