Refilling refrigerant
Check the type of refrigerant to be used on the machine nameplate.
Precautions when adding R410A
Fill from the liquid pipe in liquid form.
R410A is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal
operation.
1) Before filling, check whether the cylinder has a siphon attached or not. (It should have something like "liquid filling siphon
attached" displayed on it.)
Filling a cylinder with an attached siphon
Stand the cylinder upright when filling.
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects from entering.
7.
Charging with refrigerant
CAUTION
Even though the stop valve is fully closed, the refrigerant may slowly leak out; do not leave the flare nut removed for a long
period of time.
• If the total length of piping for all rooms exceeds the figure listed below, additionally charge with 0.21oz/ft (20g/m) of
refrigerant (R410A) for each additional piping length.
Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.

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.
