2. HEALTH AND SAFETY NOTES
PURELAB Ultra products have been designed to be 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.
2.1 Electricity
It is essential that the electrical supply to the PURELAB Ultra is
isolated before any items are changed or maintenance work
performed.
The ON/OFF switch is located at the left-hand side of the unit. The
mains power lead is located just behind the ON /OFF switch.
WARNING! THIS APPLIANCE MUST BE EARTHED.
The main water supply should be isolated and residual pressure
released prior to removal of any Purification Packs or carrying out
work on the unit.
Switching off the electrical supply will isolate the source of mains
water pressure.
2.2 Ultraviolet Light
WARNING! UNDER NO CIRCUMSTANCES SHOULD
THE LAMP BE CONNECTED AND
ACTIVATED WHEN OUTSIDE THE
HOUSING.
The Genetic, Analytic and Ionic units are fitted with an ultraviolet lamp.
The UV lamp is enclosed in a stainless steel chamber ensuring that
the operator will not be exposed to UV light.
2.3 Sanitization Chemicals
During the sanitization cycle a CT1 sanitization tablet is used and
relevant safety information is included in this handbook. A safety data
sheet conforming to COSHH regulations is also provided with the
tablets and should be read before a tablet is used.
2.4 Control of Substances Hazardous to Health (COSHH)
Material safety data sheets covering the various replaceable
Purification Packs are available upon request. Contact your local
supplier or distributor.

3. PRODUCT AND PROCESS
DESCRIPTION
3.1 Product Description
The PURELAB Ultra water purification unit has been specifically
designed to provide a supply of ultrapure water with very low levels
of impurities for laboratory, medical and industrial applications.
The PURELAB Ultra can be bench, underbench or wall mounted with
an optional wall mounting kit. A range of accessories is available to
complement the unit (see Section 10. - Consumables and
Accessories, for detail).
Control Panel Dispense Nozzle Dispense Controller
Door
PURELAB Ultra
The PURELAB Ultra range of water purification units has been
designed to provide the ultimate in high purity water for laboratory
applications. The products need to be fed with pre-treated water,
typically from a reverse osmosis supply. They can be operated directly
from a ringmain feed as point of use polishers, with or without local
buffer storage, using a Docking Vessel or suitable reservoir.
Alternatively, they can be supplied from a local pre-treatment/storage
system, for example a PURELAB Prima and Docking Vessel
combination.

3.2 Process Description
Scientific
Pre-treated water enters via an inlet solenoid, passes
through a flow sensor and is pumped through the primary
purification pack, an intermediate water quality sensor, a
polishing purification pack and final temperature and water
quality sensors before being dispensed or recirculated
through a non-return valve back to the pump inlet.
The first purification pack removes most of the impurities
from the water and the intermediate water quality sensor then
measures the resistivity of the water from the first pack to
check when it needs to be replaced.
Any remaining ionic and organic impurities are removed by
the second polishing purification pack. Product water
resistivity and temperature are measured before dispense.

Pre-treated water enters via an inlet solenoid, passes
through a flow sensor and is pumped through the primary
purification pack and an intermediate water quality sensor.
The water then flows through a UV chamber, further
resistivity and temperature sensors, a polishing purification
pack, an ultrafilter and final temperature and water quality
sensors before being dispensed or recirculated through a
non-return valve back to the pump inlet.
The first purification pack removes most of the impurities
from the water and the intermediate water quality sensor then
measures the resistivity of the water from the first pack to
check when it needs to be replaced.
Purified water flows directly through the UV chamber where it
is exposed to intense UV radiation at wavelengths of 254nm
and 185nm to provide continuous bacterial control and the
photo-oxidation of residual organic impurities. The second
temperature compensated water quality sensor provides data
for TOC monitoring.
Any remaining ionic and organic impurities are removed by
the second polishing purification pack; the ultrafilter removes
pyrogens, bacteria and other microbial impurities as well as

IEC1010-1.
Rear Mounting Points
Unit Rear Mounting Points

PURELAB Ultra Operator Manual ELGA
Page 14 PURELAB Ultra Version 1 - 05/02
Electrical
The units can be connected universally to any electrical
supply in the range of 100 - 240V and 50 - 60Hz. The mains
lead is supplied with a molded plug on one end and a molded
connector to the unit on the other. The unit should be
connected to an earth. The unit includes a battery which will
require changing on a periodic basis, typically every 3-5
years. (Contact local Service provider)
WARNING! DANGER OF EXPLOSION IF BATTERY IS
INCORRECTLY REPLACED. REPLACE
ONLY WITH THE SAME OR EQUIVALENT
TYPE RECOMMENDED BY THE
MANUFACTURER (3 VOLTS, LITHIUM
CR2032). DISPOSE OF USED BATTERIES
ACCORDING TO THE MANUFACTURER’S
INSTRUCTIONS.
Drain/Flush
A semi-rigid flexible connection to a sink or suitable drain
capable of at least 2.0l/min is required. The drain point
should have a gravity fall below the level of the unit and any
connections direct to drain should have an air-break device
fitted. On the Genetic & Bioscience units a separate flush line
to drain is required. The drain and flush drain lines should run
individually to a convenient drain point.
Feed Water
The feedwater should be potable water, pre-purified using
reverse osmosis, deionisation, or distillation. If using a supply
other than reverse osmosis treated, it is strongly
recommended that a 0.2 micron membrane filter is installed
prior to remove colloidal impurities. The feedwater should
enter the PURELAB Ultra via an 8mm (5/16") O/D semi rigid
tube, and should be in the temperature range 1 to 40°C (34
to 104°F). To ensure optimum performance it is
recommended that the feedwater temperature be between 10
to 15°C.
CAUTION! Operating with feed water temperatures
outside the range from 1 to 40°C (33.8 to
104°F) will cause damage to the PURELAB
Ultra unit.
For pressurized feeds, the minimum direct inlet pressure is
0.07bar (1.0psi) and maximum inlet pressure is 0.7bar
(10psi). Higher feedwater pressures must be reduced using a
pressure regulator valve (Part No. LA575).
Reservoir feeds to the PURELAB Ultra unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure of approximately 0.07bar
(1psi).

3. CUT a clean square end on an 8mm OD semi
rigid drain tube.
4. PUSH tube into connector.
Step 2 - Connect Water Inlet
1. Connect 8mm tube from the PURELAB Ultra
inlet to the inlet strainer.
2. Connect the inlet strainer to the pre-purified
water supply.
Step 3 - Connect Drains
1. Connect 8mm tube from the drain and UF drain
(if fitted) and direct to a suitable drainage point.
CAUTION! The drain and flush lines should allow a
gravity fall to drain with no restrictions.
CAUTION! If the water supply is at a pressure greater
than 0.7bar (10psi) fit a pressure regulator
(LA575).
