Refilling the 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.

It 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.)

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

6.

Charging with refrigerant

1) If the total length of piping for all rooms exceeds the figure listed below, additionally charge with 

20g

 of refrigerant (R410A) 

for each additional meter of piping.

For cooling only

• Cooling only models (4MKS75) are chargeless. There is no need to charge 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.

Outdoor capacity class

4MXS68, 3MXS68

Total length of piping for all rooms

30m

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.
