8.4 Repairing the refrigerant circuit
Observe notes on servicing (see Ch. 8.1).
If it is suspected that the refrigerant has been leaking it is not possible to judge how
much refrigerant remains in the refrigeration circuit. It is therefore necessary to remove
all the remaining refrigerant and dispose of it. Refill with new refrigerant once the leak
has been repaired.
CAUTION
Damage to the unit caused by incorrect refrigerant
Unsuitable refrigerant causes faults and damage.
▶
Use only R410A refrigerant.
CAUTION
Damage to the compressor caused by excess refrigerant
Over-filling can lead to bursting and therefore cause injury.
▶
Adhere to exact filling quantity.
▶
The quantity of refrigerant required can be found on the name plate.
▶
Use a suction device to completely drain any refrigerant from the unit.
▶
Dispose of drained refrigerant in an approved manner.
▶
Check refrigerant pipework is not leaking (see Ch. 5.1.3).
▶
Gradually fill liquid R410A refrigerant (see Ch. 8.4.1).
▶
Close pipe connections.
