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.
This 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.
There is a siphon pipe inside, so the
cylinder need not be upside-down to
fill with liquid.
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
6.

Charging with refrigerant

• 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.

Total length of piping for all rooms
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.
