Boiler tube electric heat components and parts series of the Model GYSG
一.Use
 The tube electric heat component of Model GYSG, is only suitable for widing open type , closed water and water which heat inside of circulatory system of trough neutralization to use.


二.Operation instructions
 1.The effective length of the electric heat component of Model GYSG is used when must all invade the liquid , this component can't heat the gas or the solid thing .
 2.The working voltage of the electric heat component can't exceed 1 of its specified value . 1 time, environment temperature is not greater than 95%. The outer cover should be grounded effectively.
 3.The electric heat component should be preserved in the dry place. Put it at less than 1MΩ, can can resume to ground insulating resistance after ranking tide 4h among 200 about oven for a long time.
