2-3 LOCATION

Install the CLD Analyzer Module in a clean, weather-pro- tected, vibration-free location free from extreme temperature variations and moisture. For best results, install the instrument near the sample stream to minimize sample transport time.

The analyzer should be installed within ±15° of horizon- tal.

NOTE

Unrestricted air flow to the rear of the Analyzer Module is critical to its performance and reliablilty.

2-4 GASES

a.Gas Conditioning (Sample Handling)

NOTE

All gases must be conditioned before supplying!

The gases must be

-dry

-free of dust (filtered for particulates down to two microns)

-free of aggressive components affecting gas paths materials (e.g. by corrosion)

-free of Ammonia etc. in order to prevent crystallin formation

Operating ambient temperature is 0 °C to 45 °C (32 °F to 113 °F). Temperature change should not exceed 10 °C (18 °F) per hour. The same temperature range restrictions apply to the location of the air and span gas cylin- ders.

before entering the Analyzer Module.

The gases should have a dew point 5 °C (13 °F) below coldest ambient temperature.

CAUTION

EXTERNALLY RESTRICT SAMPLE/CALIBRATION

GAS FLOW TO LESS THAN 2,200 cc/min.

Damage to internal components may occur if this flow level is exceeded.

No restrictor is provided in the sample inlet of this module. For those users who cannot externally limit sample flow, contact your local service or sales office.
