Introduction
Product Overview
The Barnstead DIamond TII is a tap-fed water purification
system designed to be simple to use and to provide
reagent grade water that exceeds ASTM Type II, and
NCCLS/CAP Type I standards. It uses a thin film compos-
ite reverse osmosis membrane with pretreatment to pro-
duce RO water that is then polished using a two-stage
deionization process combined with UV oxidation and a
0.2 micron final filter.
The % of the rejection between incoming and reverse
osmosis product water is monitored and an indication is
provided to the user if the RO water quality is unaccept-
able. Incoming and RO pressure are provided by pres-
sure sensors located inside the unit. The DI water purity
is continuously sensed by a resistivity cell and displayed
on a graphical display.
RO operation is automatic and works independently of the
DI system to fill the external reservoir as determined by
sensors in the reservoir.
The DIamond TII is not shipped with pretreatment and DI
polishing cartridges or a final filter. These must be
ordered separately. The start-up kit containing these
components can be ordered using part number D502138
for all units.
The electronics can be verified and calibrated utilizing a
N.I.S.T. Traceable Calibration Module. See accessory
ordering information.
Please read the instructions carefully to ensure that you
receive maximum benefit from the DIamond TII. Also,
please fill out and return the enclosed warranty registra-
tion card as it will help us assure you of proper warranty
coverage.

Cartridge and Membrane
Installation (See Fig. 6)
Your DIamond TII has been shipped with one membrane
(for 12 lph unit) or two membranes (for 24 lph unit), that
you will install. The Startup Kit (D502138) includes a pre-
filter, MPS cartridge and carbon filter, and must be pur-
chased separately. To prepare your DIamond TII for opera-
tion, disconnect the unit from the power supply if connect-
ed.
Prefilter Installation
Particulates can damage your membranes, resulting in
premature membrane failure. Therefore, your DIamond TII
uses a prefilter to remove particulates from your feed
water. Install the prefilter as follows:
1. Open the front left door.
2. Remove the prefilter (Part Number D502113)
from its packaging and wet the o-rings with water.
3. Insert the prefilter upright into the left position
upper and lower quick disconnects and push until
firmly connected. For easier installation, connect
bottom first.
MPS Cartridge Installation
The MPS cartridge contains a slow dissolving anti-scalant
material. The anti-scalant material combines with water to
prevent scale buildup on the membrane surface.
Install the MPS cartridge as follows:
1. Remove the MPS cartridge (Part Number
D502114) from its packaging and wet the o-
rings with water.
2. Insert the MPS cartridge upright into the middle
position upper and lower quick disconnects and
push until firmly connected. For easier installa-
tion, connect bottom first.

Note
Figure 2 shows the correct
sequence of prefilter, MPS and
carbon filters. Cartridges must be
installed in the correct order to
operate properly.
Note
It will be important to replace
the MPS cartridge once the
material is half dissolved.

Carbon Filter Installation
Chlorine can also damage your membranes, resulting in
premature membrane failure. Therefore, your DIamond TII
uses an extruded carbon filter to remove chlorine from your
feed water.
Install the carbon filter as follows:
1. Remove the carbon filter (Part Number D502115)
from its packaging and wet the o-rings with water.
2. Insert the carbon filter straight into the right posi-
tion upper and lower quick disconnect and push
until firmly connected. For easier installation, con-
nect bottom first.
