5.8 Long piping length and high drop The max. high drop can be up to 50m when outdoor is lower than indoor. And the max. single way total pipe length can be up to 300m. 5.9 Easier maintenance a. Auto diagnose function The PCB will check the unit automatically, if there is error such as compressor wiring, sensor, communication etc., the PCB will indicate failure code via the LED or the wired controller. Many test modes or backup running modes are possible for easier test running and troubleshooting. b. Auto restart function The unit has memory function, when the power is cut off, the unit will memorize the operation state at the moment, when the power comes again, the unit will run as the previous state. 5.10 Reliable performance a. High COP High efficiency and great energy saving are the purchased aim for every air conditioning manufacturer. Haier MRVII has been designed to get high COP from the reasonable structure and the excellent electric system. HEATING COOLING 8HP COP 4.24 EER 4.28 10HP COP 3.95 EER 3.80 12HP COP 4.12 EER 3.90 14HP COP 3.85 EER 3.25 16HP COP 3.90 EER 3.20 Cooling operation condition: indoor temp is 270CDB/190CWB; outdoor temp is 350CDB/240CWB; Heating operation condition: indoor temp is 200DB, outdoor temp is 70CDB/60CWB. b. Approved for RoHS certificate All the parts in the unit have been approved for RoHS certificate. The parts are in conformance with RoHS directive. Thus Haier MRVII will be environmental for human and nature. The directive is to approximate the laws of the Member States on the restrictions of the use of hazardous substances in electrical and electronics equipment and to contribute to the protection of human health and the environmentally sound recovery and disposal of waste electrical and electronic equipment. c. Less chance of refrigerant leakage The connection type of outdoor gas stop valve is brazed, therefore it is not easy to leak any refrigerant. G R U P A d.o.o. 11
