GAS ANALYZER 345

Drain Filter

The drain filter is located to the right of the filter bowl assembly and protects the drain

pump from clogging. The drain filter is a disposable plastic filter. If the filter starts to clog,

then water can accumulate in the filter bowl. The drain filter is typically replaced every

two to three months, depending on usage.

Replacing the Drain Filter

The drain filter is held in place with two hose clamps. Remove both hose clamps from the

filter. The larger end points toward the filter bowl. Replace the filter and reattach the hose

clamps.

Perform a Leak Test to assure proper sealing. (See Section Leak Test on page 349.)

Check Valve

The red check valve is located on the drain hose near the connector. The check valve

prevents water from backing into the Gas Analyzer. The removable center cartridge must

be cleaned every two weeks to assure that the hose does not clog.

To clean the Check Valve, do the following:

1. Twist the check valve counterclockwise to open.

2. Remove the brown center cartridge. Note that the spring side of the valve is located on

the half of the check valve nearest the Gas Analyzer.

3. Soak the cartridge in a small pan with mild detergent and warm water for an hour to

remove particles and oils from around the seal.
