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
GWP
(1)
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).
Precaution for servicing
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.
<5 m: See "Total charging weight of the refrigerant (after a leak, etc.)"
on page 9 .
Additional charging of refrigerant
 The additional charging amounts relate to the refrigerant piping
length as in
"Maximum total one-way piping length" of the table
in paragraph "Allowable pipe length and height difference" on
page 5 .

Over 30 m, please add refrigerant quantity according to
following table.
For future servicing, mark with a circle the selected amount on the
tables below

NOTE National implementation of EU regulation on certain
fluorinated greenhouse gases may require to provide
the appropriate official national language on the unit.
Therefore, an additional multilingual fluorinated
greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of
that label.
When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.

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.
