DEFROST

When ice builds up on the ambient coils defrost is initiated by 
operating the machine in a cooling mode. The two refrigerant 
circuits will be defrosted individually without affecting each 

other for dual circuit units. When one system is in defrosting, 
the other must be working in heating mode even though it is the 
time to defrost.
