  • Page 7: Installing The Indoor Unit

    - Audax Pro 6-9 V2 outdoor unit (hereinafter referred to as outdoor unit or Audax Pro 6-9 V2). Magis Hercules Pro Mini 6-9 is perfectly operational only if the two units are correctly powered and interconnected. The UI MHPM indoor unit was designed solely for floor installation for heating and air conditioning and to produce domestic hot water for domestic use and similar purposes.
  • Page 8 Check the environmental operating conditions of all parts relevant to installation, referring to this booklet. If installing a kit or servicing the appliance, always empty the system’s domestic hot water circuit first so as not to compromise the appliance’s electrical safety (Par. 2.9, 2.10). Always disconnect the appliance from voltage and, depending on the type of operation, decrease the pressure and/or bring it to zero in the gas and DHW circuits.
  • Page 9 They must be connected to a central heating system and domestic hot water circuit suited to their performance and capacity. The appliance is built to also operate in cooling mode. If cold water production, during summer, could interfere and damage the central heating only systems, necessary precautions must be taken to prevent that an unintentional production of cold water enters the heating only system.
