Page 4 IMPORTANT NOTICE C A U T I O N This product shall not be mixed with general house waste at the end of its life and it shall be retired according to the appropriate local or national regulations in an environmentally correct way. Due to the refrigerant, oil and other components contained in heat pump, its dismantling must be done by a professional installer according to the applicable regulations.
Page 5 IMPORTANT NOTICE TECHNICAL PARAMETERS English Following Regulation EU No. 517/2014 on Certain Fluorinated Greenhouse gases, it is mandatory to fill in the label attached to the unit with the total amount of refrigerant charged on the installation. Do not vent R32 into the atmosphere: R32 are fluorinated greenhouse gases covered by the Kyoto protocol global warming potential (GWP) R32 = 675. Tn of CO equivalent of fluorinated greenhouse gases contained is calculated by indicated GWP * Total Charge (in kg) indicated in the product label and divided by 1000.

Page 14: General Information
1.1 General information Hisense R32 Hi-Therma series units produce heating and domestic hot water like any oil or gas boiler, but transforming renewable energy from the outside air into heat. Air to water heat pumps extract the free energy present in the air, which is enough to heat a home up to a comfortable temperature, even on the coldest winter day.
Page 15 General information 1.1.2 Line-Up of Hi-Therma Monobloc Hi-Therma Monobloc is a monobloc air to water heat pump system composed by only a special outdoor unit, which carries out the function of an air-to-water heat pump. This results in an excellent solution when installation space available is limited. Hi-Therma Monobloc is designed to be installed outdoors, in any kind of dwelling (house, apartment, villa…), whether in a new construction or in an existing building.
Page 16: Summary Of Operations
General information 1.2 Summary of operations Space heating Hi-Therma units are factory-supplied ready for space heating operation. Different heating installation configurations can be selected, providing a comfortable atmosphere all year long, even in the coldest climates: The air to water heat pump is sized to provide 100% of the heating requirements on the coldest day the year.

Page 201 Control configuration for OU 11.2 Defrost Operation < Defrost Operation > The following defrost operations, “Standard Defrost”, “Forced Defrost” and “Manual Defrost” are available. (1) Standard Defrost This operation starts according to the outdoor temperature, the outdoor evaporating temperature and the operating time. (2) Forced Defrost This operation starts when the indoor unit repeats Thermo-ON/OFF* operation and therefore cannot start the “Standard Defrost.”...
Page 202 Control configuration for OU (2) Forced Defrost The “Forced Defrost” starts when all the following conditions are met. (a) The reversing valve is “OFF” for more than 120 minutes. (b) The outdoor temperature is 10 °C or lower. (c) The accumulated heating operation time is more than 60 minutes. (The accumulated time is reset when the operation is stopped or the defrost operation is performed.) (d) The compressor is operated continuously for more than 90 seconds.
