(d) When charging R-410A, ensure that only liquid is being withdrawn from the cylinder or can. This is
to ensure that only the original composition of R-410A is being delivered into the system. The
liquid composition can be different from the vapour composition.
(e) Normally, the R-410A cylinder or can is being equipped with a dip pipe for liquid withdrawal.
However, if the dip pipe is not available, invert the cylinder or can so as to withdraw liquid from the
valve at the bottom.
