  • Page 5: General Description

    EVAPORATIVE HUMIDIFIER OPERATING PRINCIPLES FISAIR evaporative humidifiers are units designed to increase the water vapour content of the treated air, by making use of the natural evaporation of water from its liquid phase. The air supply being treated is passed through a cellular panel dampened using an irrigation system.

  • Page 20: Installation Requirements

    HEF2 Series MANUAL INSTALLATION REQUIREMENTS. GENERALITIES In order to optimize maintenance/installation, humidifiers must be placed on a level waterproof surface, with a drain or run-off, so possible leaks can be dealt with during installation, set up, operation and maintenance. Assembly inside an air handling unit must ensure the air being treated passes through the evaporative panels, by closing off the perimeters adequately to prevent possible by-passes of the air flow.
  • Page 21 ASSEMBLY INTO AIR HANDLING UNITS (A.H.U.) HEF2 Series humidifiers are normally used in conjunction with the air handling unit or A.H.U., after the (pre) heating coil and before the cold and/or (post) heating coil, as shown in the diagram below.

The importance of constant bleed-off based on conductivity Water evaporates because the water vapour pressure is higher in the evaporative panel than in the air passing through it. Since only the water evaporates, dissolved mineral salts remain in solution, which gradually increases their concentration, despite new water being added to compensate for the evaporation.

    5. The access door to the HEF2E in the AHU must have a darkened sight glass installed. START-UP RECOMMENDATIONS The operation of the FISAIR HEF2 Series evaporative humidifier is mainly determined by the irrigation of the evaporative panels. The humidifier will work as such whenever there is a current of air passing through it and the water pump irrigates the panels.
  • Page 78 HEF2 SERIES WITH EXTERIOR AIR OR INSTALLED IN AN AHU OUTDOORS All units using the HEF2 Series with exterior air must stop the pump and drain the water tank in the event of preheater faults. Units for adiabatic cooling of the return air must drain the water tank water during the winter.

    16.2 Cleaning 16.2 A. General An inspection, emptying and cleaning plan must be established for the HEF2 Series depending on the treated air and feed water quality. Evaporation humidifiers should be cleaned regularly to prevent contamination. All the component surfaces (panel, pipes and especially the water deposit) must be disinfected with an appropriate solution.

  • Page 81: Cassette Cleaning Protocol

    [Remark 1: Do not remove top cover]: Do not remove the individual irrigation header distribution. [Remark 2: Only use for high efficiency inorganic panel FISAIR]: If you have an inorganic panel or an organic panel with glued slats, this cleaning process cannot be carried out. For these cases use a weak acid solution such as citric acid or acetic acid dissolved in aqueous solvent.
  • Page 82 HEF2 Series MANUAL The procedure below should be followed: 1. Preparing the cleaning solution: The aqueous solution mixture consists of water (solvent) and household cleaning product based on oxigen (solute) in the proportions indicated by the manufacturer. Add the solute to the water and stir it completely.
  • Page 83 HEF2 Series MANUAL 3. Remove the panel from the container and wash it with the sprayed water hose. If the foam is not completely removed, reinsert the Cassette into a container with clean running water. Once the foam has completely disappeared, remove the Cassette from the container and wash it again...

  • Page 84: Disinfection

    Remark: The manufacturer’s safety steps for the disinfectant solution should be followed. The inorganic high efficiency panel the HEF2 Series cassettes includes agents, such as silver ions, that inhibit the growth of bacteria and fungi.
