    AHU to enable the safe and correct use of an AHU con- structed by EUROCLIMA. The target group of this instruction manual are all persons who are di- rectly involved with transport, assembly, commissioning and installation, operation, maintenance, troubleshooting and disassembling (see also chapter 2.5 (Staff selection and qualification)).

  • Page 6: Intended Use / Foreseeable Misuse

    Generally, a HVAC specialist, knowing the exact application of the AHU, generates a specification, in which customer requirements for the AHU are defined. The properties of the AHU, specified by EUROCLIMA, are agreed with the customer and are stated on the technical data sheets and draw- ing of the AHU.

  • Page 7: Foreseeable And Considered Misuse

    In this case, corrosion of the AHU or inappropriate filtration of the air could be a result of a planning error, for which EUROCLIMA de- clines and does not accept any responsibility, because the AHU is built according to the confirmed specifications.

    For example, a Sling/ belt with hook. The ropes, hooks and crane lugs used must be suitable for the load, see WARNING! chapter 3.4.1 (Weight specifications of ZHK Nano AHUs and additional parts).The influence of the temperature on the load capacity must be taken into account.
  • Page 20 Before lifting, it is therefore important to en- sure that the load-bearing equipment is correctly routed and that the force is applied evenly, see chapter 3.4.3 (Lifting of ZHK Nano AHU by crane lugs).

  • Page 21: Lifting Of Zhk Nano Ahus

    The AHUs ZHK Nano types (sizes) 45, 55 and 65 are usually delivered as monoblocs. Monoblocs are AHUs that can be lifted as a single section. In case of the AHU ZHK Nano series, this applies to variants with plate heat exchanger and heat wheel of the types (sizes) 45, 55 and 65, see Fig- ure 7.

  • Page 22: Weight Specifications Of Zhk Nano Ahus And Additional Parts

    AHUs types (sizes) 45, 55 and 65 see Table 3, and for AHUs type (size) 80 see Ta- ble 4. Up to these maximum weights ZHK Nano AHU’s may be lifted by using the delivered crane lugs. The delivered crane lugs may be used for lifting ZHK Nano AHUs up to these maximum weights.

  • Page 50: Frost Protection For Plate Heat Exchanger

    At low temperatures and high air speeds, the condensate in the plate heat exchanger can freeze and ice over. For devices supplied by EUROCLIMA with control, this is prevented by pressure monitoring of the plate heat exchanger and the temporary adjustment of the supply air volume flow.

  • Page 51: Commissioning

    Instruction Manual ZHK NANO For AHUs with integrated control and lighting, an additional power supply for the lighting must be provided and separated from the power supply for the control cabinet. This ensures that the light also can be switched on during repair work, despite the main switch being switched off (prerequisite for access to the AHU).

  • Page 52: Heat Exchanger

    The air density at the measuring point is to set up manually, depending on sea level, temperature and humidity. In most cases, 1.2 kg/m³ is a suitable value. For AHUs supplied by EUROCLIMA with control, the airflow rate sensors are already preset. 8.1.2 Heat exchanger The heat exchangers, fittings and valves shall be tested for tightness and integrity.

  • Page 53: Air Filters

    The external pressure drop is higher than indicated on the technical data sheet. Possible closed fire or VAV dampers in the duct If the airflow is incorrect and support is required on this matter, please contact EUROCLIMA. 8.2.1 Vibration verification Check on the quiet running of the fan.

  • Page 54: Maintenance

    If a frequency converter is used for running the fan, then the resonant range can be suppressed directly there. At AHUs with EUROCLIMA control, the resonant range can be suppressed. For that purpose, the appropriate setting of the software must be done at the commissioning process.

  • Page 55: Electrical Connection, Control Cabinet

    DANGER! Please note that EUROCLIMA is not responsible for damage caused by improper handling of sol- vents and cleaning agents, and our company would not be liable for resulting mechanical damage. Solvents and cleaning agents should not contain alcohol for use on coated surfaces.

  • Page 56: Fan

    All filters should be checked for tightness and fit, because otherwise they could be sucked in and could lead to damage and/ or poor functioning and quality. If AHUs are equipped with EUROCLIMA control, then a corresponding warning message is dis- played on the HMI (see Figure 77) when the differential pressure limitation is reached.

  • Page 57: Panel Filters

    Instruction Manual ZHK NANO Figure 77: Warning message filter If such a warning message is displayed, then appropriate actions have to be taken immediately (e.g. change of air filters). 9.3.1 Panel filters Dry panel air filters (cleanable). The contamination level of the filter can be controlled by the differ- ential pressure drop (check every 14 days to 1 month).

  • Page 58: Electric Heater

    Check built-in safety devices and electrical parts for proper functioning. 9.5 Dampers EUROCLIMA dampers of Type J are nearly maintenance free. Check for dirt, damage and corro- sion, clean if necessary with compressed air or steam jet. Check the function and correct rotation.
