  • Page 5: General Information

    Technical manual ecoGEO HP 1. General Information This manual contains the necessary information to install the heat pump. Read this manual carefully before installing the equipment. Keep this manual handy for future reference. This manual contains two different kinds of warnings that should be heeded. ▪...
  • Page 6 Technical manual ecoGEO HP Refrigerant The heat pump uses R410A refrigerant as operating fluid. This refrigerant is not harmful to the environment as it does not contain chlorine, and therefore does not contribute to the destruction of the ozone layer. Under normal operation of the heat pump the toxicity of the refrigerant is nil and there is no risk of explosion.

  • Page 7: Disposal

    DANGER! ▪ he heat pump must be supplied with an external switch that can shut off all the circuits. Ecoforest recommend installing one external automatic breaker in each external power supply (control, internal auxiliary equipment and drive).
