Section 8.0 Maintenance

8.1Overview

The 56 Analyzer used in the Clarity II turbidimeter needs little routine maintenance. Clean the analyzer case and front panel by wiping it with a clean soft cloth dampened with water ONLY. Do not use solvents, like alcohol, that might cause a buildup of static charge.

A few of the components of the analyzer are replaceable. See Tables 8-1 and 8-2.

WARNING

Explosion Hazard. Do not disconnect equipment when a flammable or combustible atmosphere is present.

8.2Sensor

8.2.1Cleaning the sensor

Clean the sensor by rinsing it with water followed by wiping with a soft tissue. If water is inade- quate, wash with a mild detergent solution followed by thorough rinsing with water. Do not scratch the lamp or photodiode windows.

If mineral scale is present, use a dilute acid solution applied with a cotton swab to clean away the deposit. Rinse thoroughly with water.

Do not use abrasive cleaners or solvents.

8.2.2Replacing the lamp/LED board

The USEPA-compliant sensor uses a tungsten filament lamp (PN 1-0901-0004-EPA) as the light source. The lamp has an expected life of about one year. The ISO-compliant version uses an infrared LED (PN 1-0901-0005-ISO). Its expected life is five years. The 56 analyzer continuously monitors the source intensity and corrects for changes in source intensity caused by age. When the source intensity becomes too low, the analyzer warns the user. The user should replace the lamp as soon as possible.

To replace the lamp/LED board:

1. Turn off power to the analyzer.

WARNING

Explosion Hazard. Do not disconnect equipment when a flammable or combustible atmosphere is present.

2. Remove the sensor from the measuring chamber and disconnect the cable.

WARNING

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process temperature is lowered to a safe level!
