Easy and fast installation Economical operation ■■ Integrated hydronic module -- High-pressure centrifugal water pump -- Water filter protecting the water pump against circulating debris -- High-capacity membrane expansion tank ensures pressurisation of the water circuit -- Overpressure valve, set to 4 bar -- Pressure gauge to measure the system pressure. -- Automatic purge valve positioned at the highest point of the hydronic module to remove air from the system. -- Thermal insulation and frost protection down to -10°C, using an electric resistance heater and pump cycling. -- Integrated water fill system to ensure correct water pressure (option) ■■ Physical features -- With its small footprint the unit blends in with any architectural styles. -- The unit is enclosed by easily removable panels, covering all components (except air heat exchanger and fans). 52 ■■ Increased energy efficiency at part load -- Eurovent energy efficiency class A and B (in accordance with EN14511-3:2013) in cooling and heating mode. The exceptionally high energy efficiency of the AquaSnap unit is the result of a long qualification and optimisation process. ■■ Reduced maintenance costs -- Maintenance-free scroll compressors -- Fast diagnosis of possible incidents and their history via the Pro-Dialog+ control -- R410A refrigerant is easier to use than other refrigerant blends Environmentally balanced ■■ Non-ozone depleting R410A refrigerant -- Chlorine-free refrigerant of the HFC group with zero ozone depletion potential -- Very efficient - gives an increased energy efficiency ratio (EER) ■■ Leak-tight refrigerant circuit -- Brazed refrigerant connections for increased leaktightness -- Verification of pressure transducers and temperature sensors without transferring refrigerant charge C A R R I E R 2 0 1 6 / 2 0 1 7
