*2: Full-scale values for both total nitrogen and total phosphorous must be greater than or equal to 0.2 and less than or equal to 100
*3: When the first range is set to low concentration, the following condition must be met for the same measurement component:
1 ≦ Second range full scale/first range full scale ≦ 50
*4: The chemical cleaning function for the sample line can be selected according to the nature of the sample
*5: The provided overflow tank can be installed in either the left/right side or rear of the main unit
*6: The distance from the provided overflow tank to the main unit should be within 1 m
*7: The sample must not contain the components that could affect the measurement (metallic ions, etc.)
*8: When tap water is supplied, flush the pipes by running the water for approximately 30 minutes before supplying.
Note
Perform the installation work while taking the features of the analyzer into consideration. Also, ensure an environment in which the equipment can operate normally. If the equipment is not operating normally due to impairment, operating conditions, or other unexpected events, take appropriate action so that no damage to the equipment will occur.
