Refrigerant charging
Caution :
This product uses R410A refrigerant. (Do not mix with R22 refrigerant)
● If the amount of refrigerant is reduced due to leakages or repairs, recover all
refrigerant from the unit and charge the designated amount by using a vacuum
pump.
● This is the inverter air conditioner whose compressor speed varies depending
on its working conditions. So, do not add or reduce refrigerant based on the
discharge/suction pressure.
● When the length of connection pipe is over 5m, add 20g of refrigerant per extra meter
from 5m.
For example: for 11m connection pipe, (11-5) x 20 = 120g to add
