Slide the tubing clamp over the silicone tubing until it is over the stainless 
steel fitting on the liquid sensor. Tighten to secure.

Repeat the procedure for the intake strainer.

For each sampling location, the intake line should be as short as practical, 
and be free of any sharp bends, coils, or loops. Install the intake line with a 
downward slope from the sampler to the sample source because:

This will assure the complete drainage of the intake line when it is air-
purged before and after each sample, and will help to prevent cross-
contamination of the individual samples. 

Complete drainage is important in freezing conditions, as any liquid slugs 
that remain could freeze and plug the line.

Place the sample intake and strainer in the mainstream of the sampling 
source, in an area of turbulent and well-mixed flow.

Also, take in account the vertical location of the intake. A position too near the 
surface may yield excess lighter materials, while a position too near the 
bottom may yield excess heavy materials. The constituents of interest must 
be considered when positioning the intake strainer.

A broad range of bottle configurations are available for the 900 Composite 
Sampler. Refer to 

Install the optional full bottle shut-off into the bottle cap using the attached 
rubber grommet. Install the full bottle shut-off connector to the mating plug 
which is attached tot he sampler back panel. Insert the sample tubing into the 
cap of the bottle.
