4.7 Afxing the Teon Film

The FEP Teon option includes a teon lm and

uorinated oil. Before mounting the transmitter to

the process ange, afx the teon lm as follows:

IMPORTANT

1) Position the diaphragm so that the

diaphragm is in a upward position.

2) Pour the uorinated oil on the diaphragm

and gasket area covering it completely

and evenly. Be careful not to scratch the

diaphragm or change the its shape.

3) Afx the teon lm over the diaphragm and

gasket area.

4) Next, carefully inspect the cover and try

to identify any entrapped air between

the diaphragm and the teon lm. The

air must be removed to ensure optimum

performance. If air pockets are present, use

your ngers to remove the air by starting at

the center of the diaphragm and work your

way out.

5) Position the gasket on the Teon lm.
