Precautions when adding R410A
Fill from the gas pipe in liquid form.

Filling a cylinder with an attached siphon
Stand the cylinder upright when

There is a siphon pipe inside, so the
cylinder need not be upside-down to
fill with liquid.
Filling other cylinders
Turn the cylinder upside-down
when filling.
