<!> CAUTIONS
• "Minimum Area for installation" might be different by revision of IEC regulation. "Minimum Area for installation" should be
selected in accordance with that revision based on the local and national environment.
• The following information is according to 'IEC 60335-2-40:2018 Edition 6.0'.
• Pipe-work shall be protected from physical damage and shall not be installed in an unventilated space, if that space is
smaller than minimum area for installation.
• The unit should be installed, operated and stored in a room with a floor area larger than the minimum area.
Use the below calcuation formula to determine the minimum area.
- m
: Total refrigerant amount in the system = factory refrigerant charge + additional refrigerant amount (kg)
c
- A
: Minimum Area for installation of unit
min
- LFL : Lower flammability limit (kg/m
- h
: Height of unit installation
