Tubing Connector
Installation
Thermo Scientific
Caution It does not require much force to effect a water tight seal. Over
tightening of the adapter will create damage and subsequent leakage.
Note It is recommended that the customer supply a feedwater shut off
valve to interrupt water to the unit when cartridge replacement is
necessary.
Note Do not tighten tube fitting hex nut with a wrench. Tight
connections can be made by hand.
1. Completely disassemble the fitting. Refer to Figure 5-1 to familiarize
yourself with the names of the component parts.
2. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
3. Place the grab ring and back up ring in the hex nut in the order and
orientation shown in Figure 5-1. Thread the nut onto the connector.
DO NOT use the O - ring at this time.
4. Push the tubing through the nut until it bottoms out in the connector.
5. Remove the adapter nut and tubing. Place the O-ring over the tubing.
Be careful not to push the backing ring or grab ring further back on
the tubing when installing the O-ring.
6. Install the hex nut on the connector and hand-tighten.
7. Repeat above steps when securing tubing to the E-pure.
