2. HEALTH AND SAFETY NOTES
PURELAB Option-S US 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-S US
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.
2.3 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
The PURELAB Option-S US water purification unit has been
specifically designed to provide a supply of purified water equivalent
in quality to water prepared by single-distillation, but without the high
energy cost associated with distillation.
The PURELAB Option-S US can be bench or wall mounted with an
optional wall mounting kit. A range of accessories is available to
complement the unit. (See Section 9 - Consumables and Accessories,
for details).

3.2 Process Description
The PURELAB Option-S US process links three purification
technologies, reverse osmosis, adsorption and de-ionization and also
incorporates 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 reverse
osmosis grade water which is collected in 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-S US
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 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 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.

5. INSTALLATION INSTRUCTIONS
5.1 Unpacking the PURELAB Option-S US
The following items should be supplied with your PURELAB Option-S
US:
1. PURELAB Option-S US unit
2. Cartridge Pack LC141
3. Installation kit (LA513 or LA506)
4. Operator Manual
5. Mains Lead
5.2 Positioning the PURELAB Option-S US
Before commencing with installation and operation of the PURELAB
Option-S US 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.

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 with feedwater temperatures
outside the range 1 to 35°C will cause
damage to the PURELAB Option-S US 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 feedwater pressures must be reduced using a pressure
regulator valve (Part No. LA512).
Reservoir feeds to the PURELAB Option-S US unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure.
