1. Avoid connecting and disconnecting the coupler when pressure is applied to perclude possible     accident.
    Connection and disconnection of TYPE-SC COUPLER is possibl, however when pressure is     applied.
2. Copuler has been designed to insure complete safety, however avoid subjecting it to shock.
    Handle with care when connecting and disconnecting in piping applications.
3. Remove foreign matter from the fluid with a filter beforehand.
    If foreign matter is mixed in the fluid operation of the internal valve will be adversely efficted,     causing leakage.
4. Do not weld the coupler directly to panels and fixtures. This damages the internal seal causing     leakage and imperfect flow.
5. When disconnecting the coupler in dusty and sandy locations, always use the specified dust     cap.
6. Never tap the valve section with a hammer, ect. to bleed residual pressure.
