-Be sure to read the "Instruction for Purge Adapter"

Warning-Do not use for applications other than residue pressure releasing. If the button is pressed during dynamic pressure applied, the pressure of the main system may drop and cause unexpected
damage due to malfunction of equipment. -Do not use continuously exceeding the rated working pressure. -Do not apply any artificial impact, bend or tension. -Do not disassemble.

Caution-If the Purge Adapter is hot, use protective wear such as gloves and take special care in handling. -Do not strike the upper part of the button with a hammer or a similar tool. If the button isstiff, insert a flat head screwdriver into the groove in the Valve Holder and press the button down by leverage.
