Page 3: General
At the end of this manual, a warranty card with the following terms is attached. It is required all customers to complete this warranty card in order to use it for potential warranty claims in the future. A) It is forbidden to repair the unit without contacting HEWALEX service team. In case of any malfunction or failures, please inform us via telephone ((32) 214 17 10) or E-mail (serwis@hewalex.pl). -
Page 4: Recycling And Utilization
F) The tank installation shall avoid direct metallic connections with water pipelines. In case that you have to use metal connection ( ie, copper or steel), please apply isolation devices ( ie, PA66 Gf30 - included as free accesories for heat pump, but also availabe from HEWALEX offer lists) G) Please select correct mounting position of the heat pump unit (See installation and service point 2: Select the installation location). -
Page 5: Cost Saving
Instruction manual Heat pump water heater PCWU 200K-2.3kW/PCWU 300SK-2.3kW The COP is calculated by this fomula: Heating capacity COP = Input power The COP value generally depends on the air inlet temperature which serves as the heating source, and the rated water temperature. The higher COP value, the better performance of the heat pump. -
Page 6: Heat Pump Structure
Danfoss expansion valve Heat pumps from PCWU 200K-2.3kW and PCWU 300SK-2.3kW series are equipped with thermal expansion valve from Danfoss. The expansion valve in heat pump system is with respect to its function the counterpart of the compressor. It controls the amount of liquefied refrigerant streaming under high pressure towards the evaporator. -
