2. HEALTH AND SAFETY NOTES
PURELAB Option-R 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 Option-R 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.
2.2 Pressure
The main water supply pressure should be isolated and residual
pressure released prior to removal of any cartridges or carrying out
work on the unit.
Switching off the electrical supply will isolate the source of pressure,
but pressure trapped within the unit should be released by opening
the dispense tap until water flow stops.
2.3 Ultra-Violet Light
The PURELAB Option-R unit is fitted with an ultra-violet lamp. The
UV lamp is enclosed in a stainless steel chamber ensuring the
operator will not be exposed to UV light.
2.4 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 the tablet is used.
2.5 Control of Substances Hazardous to Health (COSHH)
Material safety data sheets covering the various replaceable
cartridges are available upon request. Contact your local supplier or
distributor.

3. PRODUCT AND PROCESS
DESCRIPTION
3.1 Product Description
This handbook covers the operator instructions for the PURELAB
Option-R unit.
The PURELAB Option-R water purification unit has been specifically
designed to provide a supply of highly purified water.
The PURELAB Option-R can be bench or wall mounted with an
optional wall mounting kit available. A range of accessories are
available to complement the unit. (See Section 10 - Consumables and
Accessories, for detail).

3.2 Process Description
The PURELAB Option-R process links four purification technologies,
Reverse Osmosis, adsorption, ion-exchange and photo oxidation and
also incorporates a re-circulation pump and an optional RO feed water
boost pump.
The unit is designed to operate from a good quality potable water
supply, and produces either 7 or 15 liters per hour of purified water
which is further purified and circulated through a treated water
reservoir.
A graphics screen displays the system status and provides control by
means of three function buttons.
The water is processed and treated by the PURELAB Option-R unit
as follows:
• Potable water enters through a strainer and inlet solenoid
valve at either regulated mains water pressure, or is pumped
by means of a feed water pump (optional), and passes
through the pre-treatment cartridge. The pre-treatment
cartridge has been designed to protect the reverse osmosis
cartridges from particulate/colloidal matter and excessive
free chlorine, which may be present in the incoming
feedwater.
• The permeate water then passes the sanitization port and
through one or two reverse osmosis cartridges, set up in
series, which split the flow into permeate and concentrate
streams. The permeate water is further purified whilst the
waste concentrate stream is passed to drain.
• The permeate water passes through a water quality sensor
which measures the conductivity of the water.
• The permeate water is drawn into the main re-circulation
stream by the re-circulation pump together with water from
the reservoir and passes through the re-circulation
purification loop.
• This water is pumped directly through the UV chamber
where it is exposed to intense UV radiation to provide
continuous bacterial control by photo oxidation and to
promote the cleavage of organic molecules.
• The partially purified water then passes through the ionexchange cartridge which removes dissolved ionic impurities
from the permeate water.
• Finally, the water is passed through a:
• Water quality sensor, which measures the resistivity of
the water.
• Temperature sensor which provides accurate
temperature measurement.
• The deionised water is either dispensed through a dispense
tap, or returns to the reservoir. An optional point of use
0.2μm bacterial filter can be fitted to the dispense tap for
added protection.
• During periods of non-use the unit will automatically operate
in intermittent re-circulation mode to maintain water purity
with maximum efficiency.
