  • Page 8 The equipment classification is shown in the illustrations of the various installation solutions on the following pages. Only professionally enabled companies are authorised to install Immergas gas appliances. Installation must be carried out according to regulation standards, current legislation and in compliance with local technical regulations and the required technical procedures.
  • Page 9 Split exahust ducts must not pass through walls of flammable material. Do not place household appliances underneath the appliance as they could be damaged if the safety valve intervenes, if the drain trap is blocked, or if there are leaks from the hydraulic connections; otherwise, the manufacturer cannot be held respon- sible for any damage caused to the household appliances.
  • Page 10 The plugs (standard supply) that come with the appliance are only to be used to fix the latter to the wall; they only ensure adequate support if inserted correctly (according to technical standards) in walls made of solid or semi-hollow brick or block. In the case of walls made from hollow brick or block, partitions with limited static properties, or in any case walls other than those indicated, a static test must be carried out to ensure adequate mount.

  • Page 11: Installation Warnings

    Make sure that the expansion vessel present in the indoor unit is sufficient for the hydraulic circuit; otherwise use the optional vessel. If you are using one or more booster pumps it is essential to install a hydraulic separator (not supplied by Immergas) down- stream of the indoor unit.

  • Page 12: Antifreeze Protection

    In the case of kit installation or maintenance of the Victrix Hybrid, always empty the system and DHW circuits first, in order to avoid compromising its electrical safety (see Parag. 2.15 and 2.16). Only for Audax.DK4. The appliance operates with R32 refrigerant gas.
  • Page 13 The antifreeze liquid must not be harmful to one's health. - The materials used for the central heating circuit of Immergas units resist ethylene and glycol based antifreeze liquids (if the mixtures are prepared perfectly). Adding glycol lowers the freezing point of water.

  • Page 14: Outdoor Unit Installation

    Therefore, it is important that: Freezing of components must therefore be prevented by performing the following actions: - A proper water treatment is performed by a specialised technician; - A glycol with corrosion inhibitors able to contrast the acids formed by glycol oxidation is selected; - Automotive glycol is not used, since its corrosion inhibitor has a limited duration and contains silicates which may obstruct or clog the system;...

    CONVERTING THE APPLIANCE TO OTHER TYPES OF GAS The gas conversion operation must be carried out by an authorised company (e.g. Authorised Technical Assistance Service). If the appliance needs to be converted to a different gas type to that specified on the data plate, request the relative conversion kit for quick and easy conversion.

  • Page 93: Fan Speed Calibration

    FAN SPEED CALIBRATION Verification and calibration are necessary, in the case of transformation to other types of gas, in the extraordinary maintenance phase with replacement of the PCB, air/gas circuit components or in the case of installations with flue extraction systems, with horizontal concentric pipe measuring more than 1 metre.
