Safety precautions

WARNING

This section provides precautions for using the product safely and correctly and to prevent injury and damage. The terms of DANGER, WARNING, and CAUTION indicate the degree of imminency and hazardous situation. Read the precautions carefully as it contains important safety messages.

Electric shock hazard

In order to prevent electric shock, be sure to ground the equipment. At this point, however, avoid connecting it to hazardous locations, such as gas piping.

Electric shock hazard

Improper terminal connection can cause an electric shock and malfunction of the equipment. Be extremely careful not to connect the terminals incorrectly.

Electric shock hazard

• Before connecting wiring to the terminal block, be sure to cut off the external power supply. Failure to do so may cause an electric shock.

• The operation panel and the terminal block cover for the rear terminal block should only be opened/closed by a person with full electrical knowledge.

Beware of waste liquid

The waste liquid contains acid, alkali, and heavy metals. When you handle the waste liquid, be sure to wear protective gloves and goggles so that you will not come in direct contact with the waste liquid. If it gets on your skin or in your eyes, rinse it off with a plenty of water immediately and contact your doctor. If you swallow it accidentally, contact your doctor immediately.

Chemical hazard

Some reagents are poisonous and thus it is extremely dangerous if they are touched by hand. When replacing the reagent bottle, be sure to wear protective goggles and gloves, and be extremely careful so that your skin will not come in direct contact with reagents. When replacing the reagent bottle, the reagent may spill off from the bottle. If it spills off, wipe it off completely.

Chemical hazard

Dissolving the reagent generates hydrochloric vapor and heat. When mixing the cleaning solution, be sure to wear protective goggles and gloves.

• Dissolve the reagent in a well-ventilated area such as a draft chamber.

• Always pour hydrochloric acid into pure water. Never pour pure water into hydrochloric acid.

• 35% to 37% hydrochloric acid is poisonous. Be extremely careful when handling it.

• If it comes in contact with your skin, rinse it off well with running water.

• If it gets in your eyes, rinse it off well with running water, and then immediately consult a doctor.

Fire or electric shock

• Do not bundle the power supply cord during use.

• Do not damage the power supply cord nor apply an excessive load to it, such as bending and stretching it repeatedly, putting a heavy thing on it.

If may result in overheating, a fire, an electrical shock, or breakdown.

Preface

Total nitrogen (TN) and total phosphorus (TP) have been defined as “Living Environment Items” under Environmental Quality Standards and Effluent Standards as part of measures to control eutrophication of enclosed bodies of water. In addition to existing COD (chemical oxygen demand), total nitrogen and total phosphorus were incorporated into regulations governing total pollution loads beginning with the Fifth Total Pollutant Load Control implemented in 2004. Measurement by automatic measurement instrument is mandatory for factories and other establishments whose waste liquid discharge volume is greater than 400

, per day.

m No principles or methods of measurement are specified for automatic measurement instrument of the total nitrogen and total phosphorus under the Total Pollutant Load Control.

Any measurement instrument complying with the standards for performance, control, and maintenance set forth in the “Manual of measurement methods for water quality pollutant load using nitrogen/phosphorus automatic measurement instrument (published by Japan's Ministry of the Environment)” can be used.

The TPNA-500 uses the ultraviolet oxidative dissolution method.

Before Using the Product

 Ultraviolet oxidative dissolution method

Principle of measurement for total nitrogen

Alkaline potassium peroxodisulfate solution is added to the sample solution. Irradiation by

ultraviolet light then causes oxidative dissolution of nitrogen compounds to nitrite ions (NO Total nitrogen (TN) concentration is obtained by measuring the nitrite ion concentration using

an ultraviolet absorption photometer. The advantage of this method is the simplified architecture of the dissolution tanks that enables dissolution to be carried out under normal atmospheric pressure at a lower temperature (100C) than thermal decomposition methods that require 120C.

Principle of measurement for total phosphorus

Potassium peroxodisulfate solution is added to the sample solution followed by irradiation with ultraviolet light, causing oxidative dissolution of phosphorus compounds to phosphoric ions

(PO potassium antimonyl tartrate are then added to the sample to bring about a chromogenic

reaction forming molybdenum blue. The total phosphorus (TP) concentration is obtained by measuring the absorbance of the molybdenum blue at the absorption wavelength of 880 nm using an absorption photometer. The advantage of this method is the simplified architecture of the dissolution tanks that enables dissolution to be carried out under normal atmospheric pressure at a lower temperature (100C) than thermal decomposition methods that require 120C.

The amount of waste liquid is approximately 17 L per month. Includes alarm output contact terminals to activate a “Full Drain Tank” alarm when the tank reaches full capacity. Tank capacity is 20 L. Check level in the tank and dispose of waste liquid as necessary.

Storage capacity is approximately 20 L of pure water. Amount of pure water consumed is approximately 40 L per month (depending on measurement range). Includes alarm output contact terminals to activate a “Lack Blank” alarm when the amount of pure water remaining is insufficient (not needed for units that use tap water for the water supply or for units with built-in pure water unit).
