4.4.3 End-of-Line Filters
WARNING!
Failure to use and maintain end-of-line filters can cause inaccurate readings and damage to internal
components, and make additional servicing necessary.
Failure to follow these warnings can result in serious bodily injury or death.
Install an end-of-line filter (MSA P/N 711561) in each sample line to decrease contaminants in the
sample lines and device.
Examine and replace the end-of-line filters at regular intervals. The appropriate interval for replace-
ment is determined by the environment of the installation.
For a list of approved parts and how to order them, refer to Section 13, "Ordering Information".
4.4.4 Connections
WARNING!
Install tubing with large enough bend radii to prevent kinking or pinching. Kinking or pinching of the
tubing can result in insufficient monitoring of an area.
Before connecting tubing to the device, clean all tubing with compressed air or nitrogen to remove
debris.
Failure to follow these warnings can result in serious bodily injury or death.
The device has Swagelok® compression fittings for connections to the sample and exhaust lines.
These fittings accept the hard and soft tubing specified in Section 4.4.1, "Tubing Material".
Do the following procedure to connect the sample and exhaust lines:
(1) Remove the cap from the compression fitting.
(2) Insert the tubing fully into the compression fitting and against the shoulder.
(3) Turn the nut until it is finger-tight on the tubing.
(4) Mark the nut at the 6 o'clock position.
(5) While holding the body of the fitting steady, tighten the nut 1 ¼ turns to the 9 o’clock position.

tubing onto the sample line tubing. Make sure
the arrow on the body of the filter (Fig. 10)
points in the direction of air flow into the sample
line.
