    Picture 2. If the casing is covered, lift the casing at the gables. _______________________________________________________________________________________ Please note that for diameters between 500 mm (19.69”) and 900 mm (35.43”) the controller of the variable drive unit will be delivered separately.

    • Please refer to Picture 3 for the force schedule and Picture 4 for the specific support positions. Pay extra attention to position 3, as it experiences significant forces during operation. • Ensure the rotor is installed on a horizontal, even surface to prevent warping and maintain factory settings.

    3. Firmly attached dirt in the rotor is easiest removed by using hot water and a mild detergent. The mild detergent may be remo- ved with high-pressure water cleaner with the nozzle placed 300 mm from the matrix. 4. If required, Heatex recommends disinfection with the substance known as LIV +45 (isopro- panol based sub- stance).

    The power belt must be positioned so that the thinner side of the belt is in constant contact with the inside of the pulley. The belt should be twisted so the thicker side is in contact with the wheel for better friction. HEATEX MODEL E INSTALLATION & MAINTENANCE MANUAL 10 (19)

    Belt tension should be 1-2% (i.e. belt length 1-2% shorter than travelled length). For power belt remove one link per meter belt to get correct tension.

    4 screws accessed on the back side on the motor plate. The screws for the motor plate are access from the external side. For inspections and minor maintenance issues the motors can be accessed via the inspection hatches if they are present. (Special casing option).

  • Page 13: Application Limits

    ENGLISH Updated 2025.04.16 Version 15 6.11 Application Limits Recommended temperature limits for rotary heat exchanger Model E are -40°C (-40°F) to +65°C (149°F). It is however important not to exceed the temperature limits on mounted components: Component Bearings -40°C (-40°F) 110°C (230°F)
  • Page 14: Conditions To Ful Ll The Hygiene Certi Cation Requirements

    • The AHU needs to be designed in such a way that the rotary heat exchanger is possible to slide out for cleaning and disinfection. • Cleaning and disinfection of the heat exchanger should be done in accordance with Heatex cleaning and disinfection instructions with the cleaning and disinfection substances prescribed by Heatex (see Mainte- nance chapter).
