5.5 Automatic defrost Heatpump Only

5.5.1 9,12kBtu/h Model

•While in heating mode operation, in order to protect the evaporator pipe of the outdoor unit from freezing, the unit is reversed to the cooling cycle to defrost the evaporator pipe of the outdoor unit.

•Defrost control is available 40 minutes after the heating cycle started and the difference of the pipe tem-perature of outdoor unit reaches above option 1.

•The defrost control is available without reference to heating operation time only if the pipe temperature of outdoor unit reaches below option 2.
