16. Charging refrigerant
16.1. Precautions
To avoid compressor breakdown, do not charge the refrigerant
more than the specified amount.
This outdoor unit is factory charged with refrigerant and
depending on pipe sizes and pipe lengths, some systems
require additional charging of refrigerant (see
"16.3. Calculating
the additional refrigerant charge" on page 32
).
16.2. 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:
a the factory refrigerant charge of the product,
b the additional refrigerant amount charged in the field and,
a+b 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).

NOTICE
Refrigerant cannot be charged until field wiring has
been completed.
Refrigerant may only be charged after performing the
leak test and the vacuum drying.
When charging a system, care shall be taken that its
maximum permissible charge is never exceeded, in
view of the danger of liquid hammer.
Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant (R410A) is charged.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes
when charging refrigerant.
When the refrigerant system is to be opened,
refrigerant must be treated according to the applicable
legislation.
