4. Sound level: is measured in a semi-anechoic chamber conversion value, measured at a position 1 m in front of the unit

at a height of 1.3 m above the floor.

5. Inter connecting refrigerant piping length is 7.5m, level difference is zero.

6. Interconnecting refrigerant piping diameters are based on the condition that the total equivalent liquid line length is less than 90 meter.

When the total equivalent liquid line length is more than 90 meter, Please refer to the installation manual to choose interconnecting

refrigerant piping diameter.
