    Dear consumer, thank you for purchasing the heat pump Neore. We hope you will be satisfied with the device which shall bring heat comfort to your house.The pump is a quite complicated device therefore pay high attention to this manual, please.
  • Page 5: Safety Precautions

    4. SAFETY The heat pump is an electrical appliance operating with voltage of 400V! It can be installed and maintained only by an authorized electrician. In case of fire do not extinguish with water or a foam extinguisher. Use only powder or carbon-dioxide extinguisher! In case of refrigerant leakage turn off all circuit breakers placed inside of indoor unit.
  • Page 7: Principle Of Operation

    6. PRINCIPLE OF OPERATION A heat pump is a device gaining low-temperature energy from a selected source and transforming it to a higher temperature level. A heat pump air-water system utilizes heat of surrounding air. Its core is a high-performance compressor which presses down the refrigerant in a hermetic circuit and expands it while using convenient features of the cooling medium.

    BASE FOR OUTDOOR UNIT The outdoor unit is recommended to be placed on a concrete base. The gap between breeze blocks shall be filled with pebbles. It allows defrosted liquid to leak deep enough and avoids frozen lumps. If you have impermeable ground, you can improve the condition by using a drainage pipe and spreading the liquid to a larger area.
  • Page 9: First Start Of The Heat Pump

    BIVALENT SOURCE Heat pumps Neore contain integrated electric boiler of capacity 6kW. The boiler compensates power loss of the heat pump at extreme conditions. When external bivalent boiler is used, it is necessary to equip it with all safety elements (temperature protection, pressure valve, el. protection). The added bivalent source is controlled by the heat pump only passively.

  • Page 27 HEAT PUMP CONNECTION TO HEATING SYSTEM Designing The heating system design quality is very improtant, as well as quality of heating water and used materials. Insufficient flow of heat transfer medium causes increase in condensing temperature and thereby significant reduction of COP (Coeficient Of Performance). Badly designed regulation system has the same effect. On the other hand, too high flow causes erosion corrosion attack.
