Note on Adding Refrigerant

Some systems require additional charging depending on pipe lengths. The standard pipe
length is 5m (16'). The refrigerant should be charged from the service port on the outdoor
unit's low pressure valve. The additional refrigerant to be charged can be calculated using
the following formula:
ADDITIONAL REFRIGERANT PER PIPE LENGTH
Connective Pipe Air Purging
Length (m) Method
≤ Standard pipe
Vacuum Pump
length
> Standard pipe
Vacuum Pump
length
CAUTION DO NOT mix refrigerant types.
Precautions on adding the R-32 refrigerant
In addition to the conventional charging procedure, the following requirements shall be kept.
● Make sure that contamination by other refrigerants does not occur for charging.
● To minimize the amount of refrigerant, keep the hoses and lines as short as possible.
● The cylinders shall be kept upright.
● Make sure that the refrigeration system is earthed before charging.
● Label the system after charging, if necessary.
● Extreme care is required not to overcharge the system.
● Before recharging, the pressure shall be checked with nitrogen blowing.
● After charging, check for leakage before commissioning.
● Be sure to check for leakage before leaving the work area.
Important information: regulation regarding the refrigerant used
This product contains fluorinated greenhouse gases. Do not vent gases into the
atmosphere.
CAUTION
Inform user if the system contains 5 tCO
case, it must be checked for leakage at least once every 12 months, according to regulation
No. 517/2014. This activity must be covered by qualified personnel only. In the case of the
situation above, the installer (or authorized person with responsibility for final check) must
provide a maintenance book, with all the information recorded, according to REGULATION
(EU) No. 517/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 April
2014 on fluorinated greenhouse gases.
