To attach this kit, complete the following steps:

1 Perform the following procedure to connect the tube adapter and pump

tube.

1 Cut the pump tube diagonally and moisten with pure water.

2 Insert the moistened pump tubing into the Teflon tubing until it is fed

completely through.

3 Cut the pump tubing together with the Teflon tubing. If the tubes are not

cut at a 90- degree angle, a leakage or blockage may occur in the

connector.

4 Slide a Teflon nut, back ferrule and front ferrule on to the tubing. The

tubing should protrude between 0.5 and 1.0 mm beyond the front ferrule.

resistance.
