Additional Refrigerant Charge

Below is an example of a paper copy of the charge calculator

It is critical that the correct information is inputted into the Gas calculation to ensure an accurate additional chargeIf the system does not have the correct amount of refrigerant charge, the performance and efficiency of the system will be significantly lower than expected

  • All refrigerant pipe Lengths and sizes e.g. 25m of 7/8, 125m of 3/8
  • Outdoor unit model number/s
  • Indoor unit capacities
  • Number of BC Boxes and model numbers (R2 system only)
  • Furthest pipe length from Outdoor unit to furthest Indoor Fan Coil
