First, it is the 'touch' texture. Generally, coarse particles are likely to blend the impurities. Second, it is to 'see' colors. PP-R pipes are mainly lime green several, consumers tend to believe that white is the best, in fact, color is not judged good or bad quality standards. Third, it is the 'smell' odors. PP-R pipe main material is polypropylene pipes does not smell good, smell the difference there, Hangzhou plant exhaust design, is likely to be blended polyethylene, polypropylene instead. Fourth, is 'pinched' hardness. PP-R pipe has a considerable hardness, casually can squeeze tube deformation, certainly not the PP-R pipe.

Fan coil units should be carried out before entering the site acceptance, do stand-alone _ two-speed hydrostatic testing and commissioning. The test pressure of 1.5 times the system working pressure. Not leak in compliance. Horizontal unit should hanger fixed, and should be easy to disassemble and repair; drainage slope to meet the design requirements, plant exhaust sunroof, condensate should be smooth flow to design the designated location for the return valve and the water should be worrying too much close to the fan coil unit installation. Connection with the pipe fan coil should adopt a flexible tubing or soft takeover (metallic or non-metallic hose) connection, the pressure value should be higher than 1.5 times the working pressure of the hose connection should be solid and should not have a horse or deflated tube. Before the device factory fins should be cleaned of residual oil, or likely to cause condensation can not smoothly and have a "smoke" phenomenon discharged into the water tray.
