1-5. Capacity compensation coefficient
¢ Compensation coefficient of pipe length
The figures give the compensation coefficient of pipe length owing to installation position (pipe
length and height difference). Pipe length and height difference are the length and the height differ-
ence between master outdoor unit and indoor unit.

¢ Compensation coefficient of frosting/defrosting (Heating
operation)
To take the effects of accumulated frost and defrosting operation on heating capacity into considera-
tion, the capacity of outdoor units should be corrected by compensation coefficient shown in the ta-
ble below.
