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.
