(d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is
to ensure that only the original composition of R410A is being delivered into the system. The
liquid composition can be different from the vapour composition.
(e) Normally, the R410A 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.
