Notes:
1.The refrigerant pipe should be thickened when the single way length is over
90m.
2.When in cooling mode, outdoor is lower than indoor; or when in heating
mode, outdoor is higher than indoor, the compensation factor should be
decreased the below value from the above fi gure.

indoor and outdoor
