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 this warning can result in serious personal 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. For the ammonia unit, install an individual end-of-line filter (P/N 711562).

Figure 11 End-of-line filter

Do the following procedure to install end-of-line filters: 1. Remove the new end-of-line filter from the bag. 2. Slide the end of the end-of-line filter with flexible tubing onto the sample line tubing. Make sure the arrow on the body of the filter (Figure 11 ) points in the direction of air flow into the sample line.

Examine and replace the end-of-line filters at regular intervals. The appropriate interval for replacement is determined by the environment of the installation.
