    1. INTRODUCTION Thank you for purchasing this appliance. It has been manufactured in full compliance with applicable safety regulations and EU standards. Please read this instruction book carefully, as it contains important information for your safety during the installation, use and maintenance of this product. Keep it at hand for future reference.

  • Page 6: Handling

    5. HANDLING The PURECLASS CL units are delivered on a pallet and protected by a cardboard box. This packaging is not suitable for being exposed to the elements. Storage of the product must be done indoors. The handling of the equipment must be carried out using forklifts suitable for the shape and weight of the equipment.

  • Page 7: Installation

    8. INSTALLATION 8.1. Introduction All models are designed to be installed hanging from the ceiling. When installing the unit, is necessary to distribute the unit weigh between the 4 supports existing in the units. Using studded rods (Ø 8 mm), it can be secured to the ceiling and levelled: Check the distances between supports in the diagrams of the section: “Dimensions and free dimensions for mainte- nance”.

  • Page 8: Equipment Lift

    8.2.1. Equipment lift To lift the equipment it will be necessary to use a lifting table or elevator. To avoid damaging the external parts of the unit, it is necessary to handle the equipment with great care, avoiding not leaning on the outer skin of the equipment. To lift the unit follow the procedure detailed in the next steps: Step 1: Carefully remove the cardboard box that protects the equipment.
  • Page 9 Using a lift, raise the equipment until the outside air couplings are positioned in the holes in the wall. Fix the equipment to the ceiling using the threaded rods (a). To prevent the transmission of vibrations from the unit to the wall and ceiling, it is recommended to use accessory 5130064900 KIT AM HRU, which is designed to be fitted inside the unit bracket (b).

Connection with air duct on the top The PB-V1 PURECLASS 800 CL plenum accessory allows directing the outside air intake and the stale air dis- charge outlet (by default on the back of the equipment) towards the top, allowing the connection to the building's ducts, when these are located on the ceiling.

  • Page 15: Condensate Drainage

    Once done, place the lower cover (C). 8.6.3. Condensate drainage Concerning the drainage system, PURECLASS CL units are available in two different versions: a) With condensate fall by gravity (without condensation pump) b) Version CP: With condensation drain pump integrated (factory mounted).

  • Page 16: Pureclass Cl With Condensation Pump (Version Cp)

    The siphon should always be full of water. Check its level periodically, refilling it if necessary. An empty siphon can cause the condensate tray to overflow and water leak through the equipment casing. 8.6.3.2. PURECLASS CL with condensation pump (Version CP) The condensate collection system consists of a tray equipped with a condensate pump that conducts the conden- sate to the edge of the equipment (bottom part in contact with the wall of the room.

    (supplied as an accessory). This is so since a single ETD can control up to 5 PURECLASS CL units. The remote control is supplied with a 10 meter length cable, which can be replaced by a cable up to 30 meters (re- commended control cable type.

  • Page 19: Connecting Electrical Accessories

    8.6.5. Connecting electrical accessories The control included in the PURECLASS CL makes it possible to work on fixed predefined flow rates, as well as assign these flow rates to different time slots. To be able to work with variable airflow rates, it is necessary to add accessories: To access the electric board see chapter "8.6.4.1.
