The manufacturer does not accept any contractual or extra-contractual liability for any damage caused by errors in installation and/or failure to observe the abovementioned regulations and the instructions supplied by the manufacturer itself.

  • Page 10: Notes On Operation Of The Appliance

    The appliance uses the water/ammoniac absorption thermodynamic cycle (H 0 – NH to produce hot water, drawing the required energy from the ground (GAHP-GS) or, in the case of the GAHP-WS, from ground water. The water/ammonia thermodynamic cycle used in the unit GAHP-GS/WS is realized in a hermitically sealed circuit, directly verified by the manufacturer to ensure the perfect tightness of all joints, thus making refrigerant top-ups completely unnecessary.

  • Page 11: Technical Manufacturing Characteristics

    The modulating function (both in terms of combustion and flow rate) combined with fumes condensation results in efficiencies of up to 172%. The GAHP-GS/WS can operate in ambient temperatures of 0°C to +45°C. The GAHP heat pump can be controlled with the CCP/DDC or with a switch on the con- sent circuit.

  • Page 28: Hydraulic Connections

    If using rigid pipes, use vibration damping couplings at the water and gas connec- tions on the appliance's service plate to prevent vibration. As other hydronic appliances, Robur heating and cooling systems operate with grid-wa- ter of good quality. In order to prevent any possible problem of operation or reliability caused by filling or top-up water, please refer to codes and norms about water treatment for thermo-hydraulic installations in civil or industrial applications.
  • Page 29 Please make sure the pipes are properly rinsed in order to remove any residue of chemi- cal substances from the pipes. Robur is not liable for ensuring that water quality is always compliant with what reported in Table 5.1 Chemical and physical parameters of water → 29.
