Refrigerant charge and additional charge – EcoTouch Ai1 Air (Zubadan)
The outdoor units come fully charged with refrigerant R410A from the facto-
ry, allowing tube lengths (one way) up to 30 m without requiring additional
charging.
If tube lengths are less than 30 m, the charge in the outdoor unit is suffi-
cient. In new units, excess refrigerant must not be drained. However, to op-
timise the unit we recommend individual adjustment of refrigerant quantity
to total volume (refer to table).
