Page 4: Idea Of Action
SERVICE MANUAL – HEAT PUMP IDEA OF ACTION The principle of the heat pump is to collect heat from the so-called low-temperature lower source (-20°C to +35°C) and transfer the heat to the high-temperature upper source (CH and/or DHW system). This process is carried out with electricity supplied to the compressor drive. - Page 5 SERVICE MANUAL – HEAT PUMP Caution - hot surfaces. Caution - moving parts. Warning - harmful substance, risk of suffocation Warning – risk of explosion. Warning – sudden (loud) noise Warning – automatic activation Warning – low temperature Warning of fire hazard substances in combination with R290 refrigerant. R290 Fire, open flame and smoking prohibited.
