NOTE
• Be sure to make setting so that liquid can be
charged.
• When using a cylinder equipped with a siphon,
liquid can be charged without turning it upside
down.
It is necessary for charging refrigerant under condition
of liquid because R410A is mixed type of refrigerant.
Accordingly, when charging refrigerant from the
refrigerant cylinder to the equipment, charge it turning
the cylinder upside down if cylinder is not equipped
with siphon.
