1.2.6 Charging Refrigerant

- REMQ8~16P8Y1B

The outdoor unit is factory charged, but depending on the length of the piping when installed,

the outdoor unit may require additional charging.

For charging the additional refrigerant follow the procedure as described in this chapter.

Refrigerant cannot be charged until all field wiring and field piping has been completed.

Refrigerant may only be charged after performing the leak test and the vacuum drying.

The refrigerant charge of the system must be less than 100 kg. This means that in case the

calculated refrigerant charge is equal to or more than 95 kg you must divide your multiple outdoor

system into smaller independent systems, each containing less than 95 kg refrigerant charge.

For factory charge, refer to the unit name plate.

1.2.6.1 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 : R-410A

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 refrigerant charge label supplied with the product.

The filled out label must be adhered in the proximity of the product charging port (e.g. onto the

inside of the service cover).

(2)

In case of multiple outdoor systems, only 1 label must be adhered, mentioning the total

factory refrigerant charge of all outdoor units connected on the refrigerant system.

1.2.6.2 Precautions when adding R-410A

Be sure to charge the specified amount of refrigerant in liquid state to the liquid pipe.

Since this refrigerant is a mixed refrigerant, adding it in gas form may cause the refrigerant

composition to change, preventing normal operation.



Before charging, check whether the refrigerant cylinder is equipped with a siphon tube or not.



Be sure to use tools exclusively for R-410A to ensure required pressure resistance and to

prevent foreign materials from mixing into the system.

Charging with an unsuitable substance may cause explosions and accidents, so always make

sure that the appropriate refrigerant (R-410A) is charged.

Refrigerant containers must be opened slowly.
