    Mono 1 Mono System 1.1 System Schema�c Figure 1-1.1: System schematic Mono is an integrated air to water heat pump system which is one-stop solu�on for space hea�ng, space cooling and dome- s�c hot water, The outdoor heat pump system extracts heat from the outdoor air and transfers this heat through refrige- rant piping to the plate heat exchanger in the hydronic system.
  • Page 7 Mono 1.2 System Configura�ons Mono can be configured to run with the electric heater either enabled or disabled and can also be used in conjunc�on with an auxiliary heat source such as a boiler. The chosen configura�on affects the size of heat pump that is required. Three typical configura�ons are described below. Refer to Figure 1-1.2.

    Mono 3 Water Pipework Water Circuit Checks Mono units are equipped with a water inlet and outlet for connec�on to a water circuit. Mono units should only be connec- ted to closed water circuits. Connec�on to an open water circuit would lead to excessive corrosion of the water piping. Only materials complying with all applicable legisla�on should be used.
  • Page 65 Mono Water Circuit Connection Water connec�ons must be made correctly in accordance with the labels on the outdoor unit, with respect to the water inlet and water outlet. If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connec�ng the water circuit: Use clean pipes only.
