࢜ If there is no additional refrigerant value for the indoor unit in the above table, refer to the indoor unit installation manual.
• If AHU kit is included among the indoor units, you must add 0.018kg(0.04lb) of refrigerant for every 1MBH of AHU capacity increase.
Note1) In case the capacity conjunction of the Hydro Unit HT exceeds 50 % among the total indoor unit, please don’t put the additional
refrigerant.
• Method to calculate total amount of additional refrigerant
– Amount of additional refrigerant depending on the pipe length (
)
– Amount of additional refrigerant for each indoor unit (

࢜ Sum of total amount of additional refrigerant and the basic amount of refrigerant should not exceed 100kg (220lb). If the refrigerant
exceeds 100kg (220lb), separate the module so that weight of the refrigerant doesn’t exceed 100kg (220lb).
Ex> If the outdoor unit’s basic refrigerant amount is 8.7kg (19.1lb), the total amount of additional refrigerant(
+
) should not exceed
91.3kg (200.9lb).
