Adding refrigerant AA
Important information regulation regarding the refrigerant used
This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Do not vent gases into the atmosphere.
• I nform user if system contains 3 kg or more of fluorinated greenhouse gases. In this case, it has to be checked for leakage at
least once every 12 months, according to regulation n°842/2006. This activity has to be covered by qualified personnel only.
In case situation above (3 kg or more of R-410A), installer (or recognised person which has responsability for final check)
has to provide a maintenance book, with all the information recorded according to REGULATION(EC) N° 842/2006 OF THE
EUROPEAN PARLIAMENT AND OF THE COUNCIL of 17 May 2006 on certain fluorinated greenhouse gases.
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 refrigerant charge label supplied with the product.
a. Factory refrigerant charge of the product: see unit name plate
b. Additional refrigerant amount charged in the field(Refer to the
above information for the quantity of refrigerant replenishment.)
c. Total refrigerant charge
d. Refrigerant cylinder and manifold for charging
>> The filled-out label must be adhered in the proximity of the product
charging port (e.g. onto the inside of the stop valve cover).
How to Calculate the Quantity of Adding Refrigerant
The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit
situation before adding refrigerant. This operation can only be performed by a qualified refrigeration specialist.
