  • Page 7: Installing The Indoor Unit

    - UE Hydro HP 5/8/12 outdoor unit (hereinafter called, outdoor unit or UE Hydro HP 5/8/12). The product Magis Hercules Mini Hydro 5/8/12 is perfectly operational only if the two units are correctly powered and interconnected. The UI MHMH 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 The manufacturer declines all liability in the event of damage caused by appliances removed from other systems or for any non-conformities with such equipment. Only a professionally enabled company is authorised to install Immergas appliances. Check the environmental operating conditions of all parts relevant to installation, referring to this booklet.
  • Page 9 For correct operation of the system, check that the minimum flow rate in operating conditions never drops below 500 l/h for Magis Hercules Mini Hydro 5-8 models and 750 l/h for Magis Hercules Mini Hydro 12 models without system integrative resistance and 1000 l/h if there is the system integrative resistance (optional).

    In order to meet the system requirements established by EN 1717 in terms of pollution of drinking water, we recommend installing the IMMERGAS anti-backflow kit to be used upstream of the cold water inlet connection of the Indoor Unit. We also recommend using category 2 heat transfer fluid (ex: water + glycol) in the Indoor Unit primary circuit (heating and/or cooling circuit), as defined in stand- ard EN 1717.

    These will also compromise the product’s compliance, and the said product may no longer be valid and fail to meet the current regulations. in regard to the above, only use original Immergas spare parts when replacing components. If additional documentation needs to be consulted for extraordinary maintenance, contact the Authorised After-Sales Service.

  • Page 92: Initial Check

    - Check the integrity of the internal insulation. In addition to yearly maintenance, one must also check the energy efficiency of the thermal system, with frequency and proce- dures that comply with the indications of the technical regulations in force.
