1. Locate the length of 3/8” O.D. tubing provided with the unit with a
quick disconnect insert on one end and a 3/8” (.95 cm) O.D. X 1/4”
(.64 cm) NPT tubing adapter on the other.
2. Install the tubing adapter onto your incoming water line. We
recommend a customer supplied shut off valve be installed in your feed
water line. Do not connect the feed water to your Nanopure
Analytical. You will connect the feedwater during the “Initial Cleaning”
procedure explained later in this manual. Note: The cartridge pack
must be installed before connecting water line.
3. If a pressure switch is to be used, see the “Installing a Float or Pressure
Switch” section for more information.
When the Nanopure Analytical flushes its membrane, the water used is
sent to drain through this connection. To install:
1. Locate the drain water tubing. This is the 1/4” (.64 cm) O.D. tubing
that is approximately 6 ft. (1.9 m.) long. The atmospheric drain fitting
is located on the lower left side of the Nanopure Analytical.
2. Route the other end of the drain water tubing to an atmospherically
vented drain and make a connection. Ensure there are no kinks in the
tubing and that it proceeds on a downward plane. Proceed to “Initial
Operation.”
To make tubing connections (refer to Figures 5-4 and 5-5):
1. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
2. *Mark from end of tube the length of insertion.
Tube size
Insertion length
1/4 O.D.
1.75 cm (11/16”)
3/8 O.D.
1.9 cm (3/4”)
3. Wet the tube end with water and insert tube straight into fitting until
it bottoms out on interior shoulder and insertion mark is no longer
visible.
4. To remove tubing, push collet toward fitting body and pull on tubing.
To reuse fitting, begin assembly at Step 1.
