About this manual

The manual begins with important safety and precautionary measures, such as turning off the power or setting SPEED CONTROL to OFF before changing pump tubes, and guidelines for handling reagents and avoiding air bubbles. It also details the required heating temperatures for different analysis modules (e.g., 107 °C for TN, 40 °C for TP, 95 °C for COD Mn) and the sequence for starting up the instrument.

Subsequent sections describe step‑by‑step operation for each analyte (TN, TP, NH₃, NO₃/NO₂, COD Mn, etc.), including sample flow rates, reagent preparation, software usage, data handling, and post‑run cleaning. Weekly maintenance procedures, such as a 30‑minute wash with 1 % active hypochlorite solution, are also provided. This manual is written in Chinese.

Frequently asked questions

What must be done before switching pump tubes?

Turn off the instrument’s power or set the SPEED CONTROL switch to the OFF position before changing pump tubes.

How often should the system be cleaned with hypochlorite solution?

The instrument should be washed weekly with a 1 % active hypochlorite solution for 30 minutes.

What are the recommended heating temperatures for the TN analysis module?

Set heater S1 to 107 °C and keep heater S2 (phosphorus‑specific) at 40 °C, but S2 should be turned off during TN analysis.

What sample flow rate is used for the NH3/SiO4 analysis?

The sample flow rate for NH3/SiO4 is set to 1.4 mL/min.
