Disconnecting the internal, source exhaust valve

When moving the QDa Detector, you must disconnect the source exhaust valve tubing. Perform
the following procedure to disconnect the tubing.

Note:

On Standard QDa Detectors, ensure that you disconnect the 6-mm O.D. tube from the

diaphragm pump’s 6-mm elbow to the 2.5-L bottle-stopper assembly (shown in the figure on

page 96

Required materials:

•

Chemical-resistant, powder-free gloves

To disconnect the internal, source exhaust valve tubing:

Requirement:

Wear clean, chemical-resistant, powder-free gloves when disconnecting the

source exhaust valve assembly.

PTFE source exhaust tube and elbow connector
(ensure a downward gradient)

Source exhaust tube
elbow connector

Exhaust trap bottle

Waste liquid drain port
