Feedwater Connection
1. Locate the length of 3/8” (0.95 cm) O.D. tubing
provided with a quick disconnect insert on one
end and a 3/8” (0.95 cm) O.D. X 1/4” (0.64 cm)
NPT tubing adapter on the other.
2. Install the tubing adapter onto your incoming
water line. Refer to Figure 4. We recommend a
customer supplied shut off valve be installed in
your feedwater line. The quick disconnect insert
will be inserted into the feedwater inlet on the
lower left corner in the rear of the DIamond TII
during the Initial Operation.
Atmospheric Drain
The RO reject and flush water is sent to drain through this
connection.
1.
Locate the drain water tubing. This is the 1/4”
(0.64 cm) O.D. tubing that is approximately 6 ft.
(1.83 m) long with a 1/4” O.D. x 1/4” N.P.T. tub-
ing adapter on one end. The atmospheric drain
fitting is located on the lower left corner in the
rear of the DIamond TII.
2.
Install the tubing adapter into an atmospherically
vented drain and route the tubing to the
DIamond TII drain connector, ensuring that there
are no kinks.
3.
Take the tubing end that has no fitting, wet the
tube end with water and insert the tube straight
into the unit drain connector until it bottoms out.
Refer to section

Tubing Installation
for more explicit details.
Reservoir Connection
Refer to the DIamond TII Storage Reservoir manual. If an
alternate reservoir is being used, refer to “Reservoir Type”
in the “System Options” section of this manual.
