Instructions for use: 
 When using this product for solar water heaters, insulation, thaw, remember to configure the leakage protection switch. 
 Band maximum use of length and load size and band size of the conductive core section, more than 10m length of the tube with heat, be sure to refer to the Design Manual for thermal design selection in order to avoid misuse. 
 Band end of irradiation crosslinked flame-retardant heat shrinkable tube fire envelope, such as the use of insulating tape, a long time will be short-circuit dedicated band of, Donze brand water heater to provide users with a special heat-shrinkable tubing . 
 For solar water heater series band, the core part of the composite made of conductive nano-materials and polymers, even squeeze wrapped in two parallel metal wires, irradiation cross-linked, with the rapid warming in cold environments, small starting current automatically adjust the size of the output power level of the water heater piping temperature, length free to cut cross-sectional, no high temperature overheating, easy to install, such as a variety of advantages, effectively prevent the preferred product of the solar water heater pipes frozen block. 

 Advantages: 
 A temperature uniformity of heating pipes, and will not overheat, safe and reliable; 
 (2) to save energy; 
 Intermittent operation, it is warming up to start fast; 
 Low installation and operating costs; 
 5 easy installation and maintenance; 
 (6) to facilitate automated management;
