For the filling loop R-134a refrigerant, use only the specified oil grade. Use of other brands of oil can cause system failure. Since PAG oil rapidly absorbs moisture from the surrounding air, observe the following precautions: - When removing any parts of the refrigerant circuit immediately plug the holes to protect against moisture; - When installing components of the refrigerant circuit remove the plug hole just before installing the parts; - Connection of all piping and hoses are made in the shortest possible time to prevent the ingress of moisture in the air conditioner; - Use only the specified refrigerant oil brands of sealed containers. In case of accidental refrigerant leaks from the system, ventilate the work area before proceeding.
Precautions for the replacement of parts of the air conditioning It is forbidden to loosen the connection parts to drain the refrigerant from the system.
