1 check it before the installation, particularly thermal parts; Installation position 2 and it must be near the evaporator, the Industrial Valves should be installed vertically, not tilted or inverted installation; 3, when installation should pay attention to make the liquid inside the heat organization always stay within the heat pack, so thermal bag should be lower than the body was carrying; 4 thermal package installed in the evaporator export levels as much as possible back to the trachea, general should stay away from the compressor suction mouth 1. More than 5 m. 5 thermal package must not be placed in a fluid from tube road; 6 if evaporator export with gas-liquid exchanger, the heat are packing in the evaporator outlet, namely before heat exchanger; 7 thermal package is usually placed on the evaporator muffler, and clingy wall bandage tightly, contact point scale should be clean, bared metal color; 8 when the pipe diameter less than 25 mm, thermal bag can be tied in the back to the top of the trachea; When diameter greater than 25 mm, can be in 45 ° to the underside of the trachea, to prevent the pipe at the bottom of the product oil etc, affect the correct thermal heat packs.
