Pretreatment system The Installation Area | 7
The Installation Area
Note: The operator is obliged to ensure, that the installation of
the pretreatment system and its operation are carried out in
compliance with all national and international guidelines,
applicable and valid for the place of installation.
Note: If necessary, measures to protect the water have to be
taken by installing appropriate components.
Take the following criteria into consideration when selecting
the installation area:
• Feed-water pressure (potable tap water) not be less than
2 bar (29 PSI) and not greater than 6.9 bar (100 PSI).
• There must be a feed-water shut off valve installed ahead
of the Smart2Pure Pro system.
• You must protect your system from frost. The
temperature at the installation area must be between
+2°C and +40°C.
• The surface on which the system is installed must be
level and stable. It should not exceed a maximum of 2%
deviation from evenness is recommended.
• A smooth wall is required when the system is to be wall
mounted. The bench or wall surface must have an
adequate load-carrying capacity (check the maximum
capacity of load the wall can sustain and the stability of
the wall). The dry and wet weight of the system is given
under section Technical Specifications.
• A low pressure check valve is recommended in the
feed-water line to prevent back flow of feed-water from
the water system. Refer to local building codes.
• Easy access for operation and control of the system.
CAUTION: The feed-water pressure to
Pretreatment system must not be allowed to go
above 6.9 bar. Install an additional pressure
reducer when the feed-water pressure is higher.

8 | Installation Pretreatment system
Installation
1. Requirements for installation:
• Screws and fasteners for wall bracket (if wall
mounting pretreatment)
• Tap water supply with shut off valve and ¾” NPT
male adapter
2. Locate Pretreatment system within 6 feet of Water
Purification system.
Wall Mounting Instructions
for Pretreatment System
Note: Before you begin mounting the system on the wall, you
must check that the strength of the wall to ensure it is suitable
for supporting the system (refer to the table “Dimensions and
weight of Pretreatment system” in the section Technical
Specifications).
Note: The system does not include screws and fasteners for
mounting, and requires minimum 4 fasteners (2 on top, 2 on
bottom).
The countertop base can be removed before wall mounting.
To remove the coutertop base, remove the 4 screws from the
bottom of unit.
1. Locate the wall bracket. Hold the wall bracket at the
desired position on the wall and check for levelness.
Mark four boreholes for fixing the wall bracket.

12 | How the Pretreatment System Functions Pretreatment system
How the Pretreatment System
Functions
When the system is in operation, tap water with a maximum
pressure of 6.9 bar flows into the system through the
feed-water Inlet connection on the bottom of the right side
panel.
The feed-water pressure is regulated to 30 psi via an internal
pressure regulator. This regulated pressure can be seen on
the Prefilter Inlet gauge.
The water then flows (upward) through the 1 μm Prefilter. The
Prefilter is used to remove particulates from your feed-water
which can damage/plug an RO Membrane downstream from
the system. A Prefilter Outlet pressure gauge shows the
pressure drop across the Prefilter by comparing the Prefilter
Inlet and Prefilter Outlet gauge. A pressure drop of > 10 psi
indicates a plugged Prefilter (which can reduce flow through
the Pretreatment system) and replacement is necessary.
Next the water flows into the MPS Anti-Scalent cartridge. The
MPS cartridge contains a slow dissolving anti-scalent material
which is designed to prevent hard water scale buildup on
down stream RO Membranes. Replace this cartridge when
the anti-scalent material is half dissolved.
After the MPS cartridge, the water flows into the Extruded
Carbon cartridge. The carbon cartridge removes chlorine
from your feed-water, which can damage RO Membranes.
Replace the carbon cartridge every 6 months. The Carbon
Outlet pressure gauge displays the pressure after the carbon
cartridge. Compare the Carbon Outlet gauge to the Prefilter
Outlet gauge to determine the pressure drop across the
carbon cartridge. Pressure drops of > 15 psi indicates the
carbon cartridge is blocked and needs replacement.
The water exits the Pretreatment system via the Outlet
connector on the bottom of the left side panel. Use a ¼” outer
diameter tube to connect to an RO system, such as the
Thermo Scientific Barnstead Smart2Pure or Pacific Series
water systems.

Pretreatment system Initial start up | 13
Initial start up
Putting the system into
operation
• Verify if all connections are secure and correct.
• Turn the feed-water ON. Verify no leaks are present in the
tubing, connectors, cartridges, etc. Turn the water
purification system (i.e. Smart2Pure Pro) downstream of
the Pretreatment system ON. Check for leaks once the
downstream water purification system starts production.
• Verify that all pressure gauges are showing pressure
readings.
• If no leaks or blockages are found, close the
Pretreatment system’s front door and allow operation to
continue.

CAUTION: Check that all connections have been
made as described in the Installation section.

14 | Maintenance Pretreatment system
Maintenance
Regular servicing of the system ensures that the quality of the
treated water will remain constant. To ensure that your
system is serviced properly we recommend that you obtain a
maintenance contract with Thermo Fisher Scientific or factory
authorized service provider. You can then be certain that your
system will have a high degree of operational reliability and
dependability.
To ensure that your system functions without any errors it
must be checked, maintained and serviced at regular
intervals, as described in these operating instructions. The
operating instructions must therefore be kept in an easily
accessible location for anyone who is using or servicing the
system.
Maintenance Intervals
Wear parts must be replaced in accordance with the following
table. The intervals have been established for the user and
depend on the actual, exact water quality and the volume of
water that is used daily.
Note: The lifetime of the wear parts is a direct function of the quality of the feed-water and the daily volume of water that is
used.

Pretreatment system Waste Disposal | 15
Waste Disposal
Note: Before returning your Thermo Scientific Barnstead
Pretreatment systems for waste disposal, contact your local
waste disposal company for proper disposal of the system
and its components. Only specially trained personal can take
the system out of operation and dispose it properly.
When the packaging is no longer needed it can be disposed
of as household waste. Systems are in conformity with EEC
Guideline 2011/65/EC.
The system is not to be thrown away as household waste but
must be properly disposed of. It can be returned to the
manufacturer for safe disposal according to EEC Guideline
2011/65/EC. We therefore request our customers in
Germany and other member States in the European
Economic Area to contact our local service center or our
headquarters.
