Maximum heating capacity

4.4 Maximum heating capacity
Tables are based on the following conditions:
The tables are based on High speed of indoor fan. To calculate the cooling capacity of medium or low speed of indoor fan,
multiply cooling capacity of high speed by Correction Curve Factor (Chapter "4.5 Correction indoor fan speed factor").
The Tables does not include decreasing capacity by defrosting operation.
