Proper installation and maintenance must be observed to protect the refrigerant system and maintain warranty coverage. Filters and refrigerant coils must be cleared of obstruction and cleaned regularly. Failure to do so will result in unit failure and will automatically void warranty. Be advised that heat pump operation will create a large volume of condensate water during the heating cycle. Refer to the operating manual for operation and installation recommendations.
