082 Precautions Installation Make sure to use seal tape for thread connection part. Using liquid seal or liquid gasket could cause stress cracking due to the organic solvent contained and lead to damage of fittings or water leakage. Make sure to use AV Adhesive No.88 (For Heat-Resistant Unplasticized Polyvinyl Chloride Pipe). Try to apply adhesive thinly and evenly. Applying too much could cause solvent cracking, etc. and lead to water leakage. Insert straight immediately after applying adhesive and hold it sufficiently to prevent "returning." When inserting, do not insert it forcibly by hammering and such. Do not drop or throw during transportation and piping. Make sure to perform a completion inspection under water pressure after curing for a sufficient amount of time following the bonding work. Do not perform an airtightness test by using air (compressed air or positive-pressure gas) as it is extremely dangerous. Do not spray or apply an organic compound to cause a negative impact to the material of pipes and fittings such as acetone, thinner, creosote, pesticide and termite extermination agent. Even if the compounds above do not touch the pipes and fittings directly, they might damage the pipes and fittings buried shallow through penetration into the soil when if spilled on the ground. Thinner Acetone Creosote If handled inappropriately, "it may cause death or serious injuries." If handled inappropriately, "it may cause injuries or physical damage." Handling Selection of Adhesive Completion Inspection Storage of Adhesive Use of Adhesive Connection Wear mask and gloves Use of Sealing Agent (Wall/Floor Penetration Part) Contact with Organic Compounds Adhesive AV cement is applicable to "Class 1 Petroleums, Class 4 Hazardous Materials" of Article 2 of the Fire Services Act. Follow the laws and regulations and municipal ordinances for storage. Avoid flammables after use and store in a cool and dark place. AV Cement is applicable to the "second class organic solvents, etc." in the Ordinance on Prevention of Organic Solvent Poisoning. If indoor usage per hour exceeds the following allowable usage, "Ordinance on Prevention of Organic Solvent Poisoning" will be applied and qualification of "operation chief of organic solvents" will be required. For details, please check with the local Labour Standard Inspection Office. Allowable adhesive usage W (g/time) = 0.4 (g/m3・time) x workplace cubic capacity (m3)Cubic capacity of room excludes a space at 4 m or higher from the floor surface. However, if the cubic capacity exceeds 150 m3, it shall be 150 m3. To prevent poisoning from organic solvents or fires, be cautious of ventilation and avoid flammables. Avoid contacting to the skin during handling, and wear organic gas mask or air-supplied respirator, protection gloves, protection glasses and others, as necessary. If contacted to the skin, rinse with soap and water immediately. Wall PVC Pipe Fitting Cracking Sealing Agent A sealing agent is sometimes used to fill a gap when penetrating piping through wall and floor. Please check with the manufacturer of sealing agent in advance as some sealing agents contain plasticizer (phthalate ester, DOP, etc.) or organic solvent that could cause a negative influence and damage or cause water leakage from unplasticized polyvinyl chloride pipes and fittings. Water Air Use of Sealing Agent (Threaded End Connection Part) Liquid Seal × Gasket Seal Tape * Exclude acetone and alcohol to be used for cleaning of pipes and fittings before connection.
