PURELAB Classic
The PURELAB Classic range of water purification units has been
designed to provide 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
Classic DI
Pre-treated water enters via an inlet solenoid and is then
pumped through the purification pack and temperature and
water quality sensors before being dispensed or re-circulated
through a non-return valve back to the pump inlet.
Ionic and organic impurities are removed by the purification
pack. Product water resistivity and temperature are
measured before dispense and will indicate when the
purification pack needs to be replaced.
The water within the unit is re-circulated through the
purification technologies to maintain purity. To reduce heat
build up the recirculation is at reduced flow rate and is set to
be intermittent (5 minutes every hour).
An optional POU filter is available if required to protect the
outlet from bacterial contamination.

Classic UV
Pre-treated water enters via an inlet solenoid and is then
pumped through the UV chamber, a purification pack and
temperature and water quality sensors before being
dispensed or re-circulated through a non-return valve back to
the pump inlet.
Purified water flows directly through the UV chamber where it
is exposed to intense UV radiation at a wavelength of 185 nm
to provide continuous bacterial control.
Ionic and organic impurities are removed by the purification
pack. Product water resistivity and temperature are
measured before dispense and will indicate when the
purification pack needs to be replaced.
The water within the unit is re-circulated through the

Electrical
The units can be connected universally to any electrical
supply in the range of 100 –240 V and 50 –60 Hz. 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 2.0 l/min is required for Classic UF and
Classic UVF versions. 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. A flexible tube
should be temporarily connected to the dispense outlet and
directed to drain during rinsing of purification packs.
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
within the feed line to remove colloidal impurities. The
feedwater should enter the PURELAB Classic via an 8 mm
(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 Classic unit.
For pressurized feeds, the minimum direct inlet pressure is
0.07 bar (1.0 psi) and maximum inlet pressure is 0.7 bar
(10 psi). Feedwater pressures up to 4 bar (60 psi) must be
reduced using a pressure regulating valve (Part No. LA652).
CAUTION! High feedwater pressures which may
exceed 4bar (60 psi) must be reduced
using a pressure regulator with built in
pressure relief (Part No. LA575).
Failure to install the correct pressure
regulator will cause damage to the
PURELAB Classic unit.
Reservoir feeds to the PURELAB Classic unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure of approximately 0.07 bar
(1 psi).
