Charging refrigerant
Important information regarding the refrigerant used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type:
R410A
(1)
GWP
value:
1975
(1)
GWP = global warming potential
Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
+the total refrigerant charge
on the fluorinated greenhouse gases label supplied with the product.
The filled out label must be adhered on the inside of the product and
in the proximity of the product charging port (e.g. on the inside of the
service cover).

that label.
Precaution for servicing
When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.
This unit requires additional charging of refrigerant according to the
length of pipe connected at the site. Charge the refrigerant to the
liquid pipe in its liquid state through the service port of the liquid stop
valve. Since R410A is a mixed refrigerant, its composition changes if
charged in a state of gas and normal system operation would no
longer be assured.
On this model it is not necessary to charge additionally if the piping
length ≤30 m.

Additional charging of refrigerant
The additional charging amounts relate to the refrigerant piping
length as in

Over 30 m, please add refrigerant quantity according to
following table.

In case of complete recharge of the refrigerant, please first
execute vacuuming. Execute this vacuuming from the
service port. Do not use the port of the stop valve for
vacuuming. Vacuuming can not be executed completely
using such port.
Position of service port:
Outdoor units have 1 port on the piping. It is
between the heat exchanger and the 4-way valve.
