Filling a cylinder with an attached siphon

Stand the cylinder upright when 
filling.

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.

Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
