Refrigerant Piping Work
5. Charging with refrigerant
• If the total length of piping for all rooms exceeds 20m, additionally charge with (R32) 20g of refrigerant for each additional
meter of piping.
NOTE:
National implementation of EU regulation on certain fluorinated greenhouse gases may require to provide the appropriate
official national language on the unit. Therefore an additional multilingual fluorinated greenhouse gases label is supplied
with the unit.
Sticking instructions are illustrated on the backside of that label.
• Even though the stop valve is fully closed, the refrigerant may slowly leak out; do not leave the flare nut removed for a long
period of time.
• Do not overfill with refrigerant. This will break the compressor.
