2. HEALTH AND SAFETY NOTES
PURELAB Prima 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 Prima 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.
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 the tablet is used.
2.4 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 Prima process links two purification technologies,
reverse osmosis, adsorption and also incorporates an optional RO
feed water boost pump.
The unit is designed to operate from a good quality potable water
supply, at 15°C and produces 7, 15 or 30 liters per hour of purified
reverse osmosis grade water which is delivered to 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 Prima 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 water then passes the sanitization port and through
one, two or three 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 is passed through a:
•Water quality sensor, which measures the conductivity of
the water.
•Temperature sensor which provides accurate
temperature measurement.
•Finally, the purified water is delivered to a treated water
reservoir.
•To ensure that the quality of the purified outlet water from
the unit is maintained at its highest level, the unit has an in-
built automated auto-rinse cycle. The auto-rinse cycle is
performed every time the process is initiated and consists of
a 1 minute high flow rinse to drain across the reverse
osmosis cartridges.

5. INSTALLATION INSTRUCTIONS
5.1 Unpacking the PURELAB Prima
The following items should be supplied with your PURELAB Prima:
1. PURELAB Prima unit.
2. Installation kit (LA513 or LA506).
3. Operator manual.
4. Mains lead.
5.2 Positioning the PURELAB Prima
Before commencing with installation and operation of the PURELAB
Prima 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 LA 610).
CAUTION!If unit is to be wall mounted, ensure it is
mounted on a substantial 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% at 31°C decreasing
linearly to 50% at 40°C, non-condensating.
The unit is in Installation Category II, Pollution Degree 2, as Safety
Standard IEC1010-1.

Page 12 PURELAB Prima 7/15/30 Version 01 09/08
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.
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") OD semi rigid tube, and should be in the temperature
range 1 to 35°C.
CAUTION! Operating with feed water temperatures
outside the range from 1 to 35°C will cause
damage to the PURELAB Prima unit.
For pressurized feeds, the minimum direct inlet pressure is
4 bar (60 psi) (6 bar (90 psi) for PURELAB Prima 30) and
maximum inlet pressure is 6 bar (90 psi). Higher feedwater
pressures must be reduced using a pressure regulator valve
(Part No. LA 512).
Reservoir feeds to the PURELAB Prima unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure.

2. Two software controlled touch pad buttons which
are used to control set-up and process control
functions.
When the PURELAB Prima unit is started for the first time after
installation the following steps should be carried out to set up system
preferences:
Step 1 - Setting Up Menu Options
SWITCH the mains power on to initialize the controller
hardware set-up sequence.
Note: Always allow the initialization process
to complete. This is indicated by the
appearance of the MENU icon on the
control screen.
PRESS the MENU button to go to the next screen to activate
the set up menu sequence.
A series of set-up screens will now be displayed. Various
control icons are used to allow you to step through the set-up
instruction process. These icons include:
•A “scroll” icon indicated by an arrow
•An “accept” button indicated by a tick 9
•A “selection” icon indicated by a 
Step 2 - Auto/Manual Restart
This allows the selection of the AUTO/MANUAL restart option.
If auto restart is selected the unit will automatically restart after
a power failure. In manual mode the unit will remain in standby.
Select the option required using the button and accept with
the 9button.
Step 3 - Audible Alarm Enabled/Disabled
This display provides the option of either enabling the audible
alarm, causing it to sound, or disabling the audible alarm
causing it to remain muted, whilst it flashes the alarm icon.
Select the option required using the button and accept with
