  • Page 11: Product Introduction

    Heat Pump Pool Heater 2 Product Introduction 2.1 Working Principle and Characteristics The pool heat pump heater is a new, efficient, energy-saving and environmentally friendly product. It uses the principle of heat pump to drive the compressor with electric energy. Through the thermal cycle, the heat absorbed in the air is transferred to the water-side heat exchanger for water supply (hot water), or the heat absorbed by the water-side heat exchanger (cold water) is released into the air through the thermal cycle.

  • Page 38 Heat Pump Pool Heater shall be followed. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. Cylinders shall be kept upright. Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
  • Page 39 Heat Pump Pool Heater Do not overfill cylinders (No more than 80% volume liquid charge). Do not exceed the maximum working pressure of the cylinder, even temporarily. (10) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
