Ikeuchi & Co., Ltd. H. Ikeuchi & Co., Ltd. VP/VEP-TPVDF (Page 1) 1. Precautions (1) Ceramic Parts The ceramic parts used in spray nozzles feature high chemical and wear resistance, but the following restrictions need to be considered: ·Use of hydrofluoric acid and concentrated alkali will lead to corrosion. ·While the material is hard, it is also brittle which can cause chipping. ·The ceramic will crack if abruptly cooled down from high temperatures (200°C). (2) Installation ·Be sure to flush the pipes before installing the nozzle to remove any dirt and foreign matter. ·Apply sealant or sealing tape to the thread of the nozzle before installation. (Recommended tightening torque: 3.03.5 N m) ·Avoid installing the nozzle immediately on or after a bend in the pipe or an elbow. Turbulence may affect the nozzle performance. ·Pay attention to the spray direction when installing the nozzle (3) Operation ·Start spraying at a water pressure of 0.050.1 MPa to avoid water hammer and then gradually increase to operating pressure. ·After spraying chemical solution, spray clean water for a while to clean the nozzle orifice and the inside of the nozzle. ·To prevent the nozzle from clogging, install strainers or use a water treatment system, depending on the water quality. (4) Use ·Do not damage or scratch the nozzle. ·Do not clean the ceramic tip with nails, pins or other hard objects, which may damage the nozzle. ·Do not apply any strong force, shock or vibration to the nozzle. ·Store the nozzle in a clean, dust-free place. ·Do not use in freezing cold environments to prevent damage to the nozzle. The nozzle body is made of plastic (PVDF) and fragile. H. Ikeuchi & Co., Ltd. 2.

Troubleshooting If there is a problem, please check the following items first. If the problem persists, please replace the nozzle. No. Problem 1 Nozzle not spraying, or the spray pattern is irregular. 2 Water leaks. Possible reason Liquid pressure is too low. Nozzle and/or strainer are clogged. Sealant or sealing tape is damaged or worn. Nozzles are not screwed in tight enough. Solution Check the pressure in the pipe and apply the proper pressure. Clean both, the nozzle and strainer (ultrasonic cleaning, compressed air, etc.). Replace the nozzle. Replace the sealant or sealing tape. Tighten the nozzles properly with a torque wrench. H.
