It is concern that pump is damaged by freezing during winter season. Without regard to stop perioed of operation, drain the liquids in the piping and pump by operating dry run after opening the drain valve on the suction piping. In case of stop pump operation for a long period(more than 1 week), the pump should be run at atmospheric pressure of discharge side for several minutes before going into normal operation. - Page 14 11-2 Inspection during operation (Daily inspection) Check the level of liquid tank and, if it is insufficient, supplement the liquid. Specially, be careful in the process which handle the chemical solution or required Air-Free circumstance. Check if liquid or air is leaked out the Joint or other parts. If necessary, fasten it again. If leakage doesn’t stop, check O-ring and/or Packing of each parts and replace the damaged O-ring and/or Packing with new one.

Accesories Back Pressure Valve According to the conditions of the piping, the discharge rate may be excessive or the pumping liquid may be continuously leaked in spite of stopping the pump which is caused by overfeed or siphon phenomena. The back pressure valve is for preventing such things. Safety Valve(Relief Valve) When the discharge pressure increases to more than a setting point due to choking the valve with debris or closing the valve, the safety valve will open automatically to relieve the pressure. - Page 20 CSME - I - 01 2019. 10. 21. 40, ANSANTECOM-GIL, SANGNOK-GU, ANSAN-SI, GYEONGGI-DO, KOREA Phone : +82-31-508-1003 : +82-31-419-3223 E-mail : cheonsei@cheonsei.co.kr Homepage : http://www.cheonsei.co.kr...
