Instruction manual

Your Barnstead TII has been shipped with
one RO membrane for the 12 lph unit, or
two RO membranes for the 24 lph unit,
which you will install. The Startup Kit
(D502138) includes a prefilter, MPS
cartridge, carbon filter, and cartridge
pack, and must be purchased separately.
To prepare your Barnstead TII for
operation, disconnect the unit from the
power supply if connected.
Note The cartridges must be installed in
the correct order to operate properly.
s
Particulates can damage your membranes,
resulting in premature membrane failure.
Therefore, your Barnstead 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.
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
installation, connect bottom first.
