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.

3.2 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 ion-
exchange 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.

5. INSTALLATION INSTRUCTIONS
5.1 Unpacking the PURELAB Option-R
The following items should be supplied with your PURELAB
Option-R:
1. PURELAB Option-R unit
2. Cartridge Pack LC141
3. Sanitization by-pass block fitted in the unit
4. Installation kit (LA513 or LA506)
5. Operator manual
6. Mains Lead
5.2 Positioning the PURELAB Option-R
Before commencing with installation and operation of the PURELAB
Option-R unit, please read and observe the following points.
Environment
The unit should be installed on a flat, level surface, in a clean,
dry environment. The unit can also be wall mounted against a
vertical wall capable of supporting the weight (for this we
recommend the use of the wall mounting kit Part No LA610).
CAUTION!If unit is to be wall mounted, ensure it is
mounted on a substantial brick or concrete
solid wall capable of supporting the
operating weight of the system. If
mounting the unit on the wall, use the wall
mounting kit and follow the instructions
included in the kit.
Note: Refer to specifications for unit weights.
The unit is designed to operate safely under the following conditions:
•Indoor Use
•Altitude up to 2000m
•Temperature Range 5 - 40°C
•Maximum Relative Humidity 80% @ 31°C decreasing
linearly to 50% @ 40°C, non-condensating
The unit is in Installation Category II, Pollution Degree 2, as per
IEC1010-1.

PURELAB Option-R 7/15 Operator Manual ELGA
Page 12 PURELAB Option-R 7/15 Version 4 08/07
Electrical
The unit 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.
Drain
A semi rigid flexible connection to a sink or suitable drain
capable of handling at least 1.5 l/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.
Feed Water
The feed water should be of good quality and comply with
specifications provided. This should enter the unit via an 8mm
(5/16") O/D semi rigid tube, and should be in the temperature
range 1 to 35°C.
CAUTION! Operating temperatures outside the range
1 to 35°C will cause damage to the
PURELAB Option-R unit.
For pressurized feeds, the minimum direct inlet pressure is
4.0 bar (60 psi) and maximum inlet pressure is 6 bar (90 psi).
Higher feed water pressures must be reduced using a pressure
regulator valve (Part No. LA512).
Reservoir feeds to the PURELAB Option-R unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure.

Step 4 - Positioning Dispense Tap
The Dispense Tap may be fitted at a high level or a low level on
the PURELAB Option-R unit, to allow for easier access when
wall mounted.
To alter the location of the Dispense Tap:
1. Switch the PURELAB Option-R off at the power
switch at the top left hand side of the unit.
2. Ensure the water supply is turned off.
3. Dissipate pressure by opening the dispense tap.
4. Open the front door.
5. Remove the LC141 cartridge. (See section 7.2).
6. Unscrew the two panel fixing screws located on
the right hand side of the door opening.
7. Remove side panel by sliding the panel to the
rear. Once unhooked, remove.
8. Remove screws holding dispense tap manifold.
9. Locate manifold in alternative position.
10. Replace panel.
11. Replace LC141 cartridge. (See section 7.2).
12. Switch electrical power on.
13. Switch water supply on.
14. Press the process button.
15. Ensure correct operation of dispense tap.
