Danger ·During repairing, the power plug should be disconnected. Before remove, install, replace parts disconnect the power plug. ·Attention don’t get electric shock. When checking current, voltage or charging never touch the connectors. When changing the parts, don’t touch the charged parts within three minutes after disconnect the plug.
Notice ·Attention the hot. The running or just stop compressor and the pipe sometimes are very hot. And the heating or just stop heater is very hot. The hot will cause scald. ·Attention the hot parts of the pipe after the welding. ·Attention the refrigerant during charge and discharge it, as it will frostbite the skin when touch it.

1>. Cut off process pipe and check the refrigerant. If there is not enough refrigerant, the default of the refrigerant system should be caused by the leaking. If the refrigerant is sufficient., it is probably block in the capillary. 2>.If the default is concentrated on the cooling system, the checking procedure is as below. a.
