Page 6: 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 32: Installation Requirements
HEF2 Series MANUAL 10. 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.
Page 33 HEF2 Series MANUAL EVAPORATIVE PANEL DRYING TIME To ensure complete drying of the cooling pad, after a work period, the air fan of the UTA must be working during the times set out in the following table: Before drying the evaporation panel, the ventilation must be stopped for 10 minutes and watering continued with the cassettes.
Page 34 HEF2 Series MANUAL USE IN AIR HANDLING UNITS (A.H.U.) FISAIR air humidifiers are normally incorporated into air-handling units after the coil as shown in figure 2. Since all the components are in service down stream, access from this side is normally enough.

HEF2 Series MANUAL 11.2 A. Connection to the water supply for filling the water tank. WATER CONNECTIONS Connect the water supply (A) to the ½” male BSP float valve (6) using suitable piping with a cut-off valve (1). We recommend the installation of a 0.5 mm light filter (2). The float valve can be regulated to set it to a range of water supply pressures, as shown in figure 1 on this page.
Page 43 HEF2 Series MANUAL Remark 3: How to avoid standing water in the water supply: o If the distance from the supply valve to the main water supply line (with continuous water flow) ≥ 2m: Install a 3-way valve, before the cut-off valve, with a return line to the main water supply line, to avoid water retention.
Page 44: Connecting The Drain To The Water Trap
The siphon must be able to drain freely and must not be connected directly to the sewer pipe. 1” BSP-H The humidifier must be disconnected automatically when the system fails. To meet working conditions according to sanitary standard VDI6022, FISAIR recommends including our BASIC CONTROL PANEL (CCB2.0) or STAGES CONTROL PANEL (CCE2.0).

Page 50: Adjusting The Constant Bleed-Off Regulation Valve
HEF2 Series MANUAL 11.2 F. Adjusting the constant bleed-off regulation valve. 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.
Page 51 Remark: The flow of the constant bleed-off cannot fall below 0,31 L/min. The flow in L/min of the bleed-off can be found on the HEF2 Series selection sheet. The adjustment is done with a flat screwdriver.

(application in English) 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 108 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.

HEF2 Series MANUAL 18. MAINTENANCE. IMPORTANT Request maintenance of your units by contacting: sat@fisair.com service@fisair.com https://ﬁsair.com/es/servicio/mantenimientos/ (application in Spanish) https://ﬁsair.com/service/maintenance/ (application in English) GENERALITIES Humidifier components are very easy to maintain, because the only active parts are the irrigation pump and the float valve.

19.2. Cleaning 19.2 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 111: Scale Formation Process
HEF2 Series MANUAL 19.2 B. Scale formation process Mains water is not pure as it contains dissolved calcium and magnesium salts (among others) that can be deposited in the form of scale. These salts can clog and harden the inorganic panel and make its water absorption more difficult, thus decreasing performance.
Page 112 [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 113 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.
Page 114 HEF2 Series MANUAL Once the foam has completely disappeared, remove the Cassette from the container and wash it again with the sprayed water hose. 4. Allow the Cassette to dry completely in the open air for as long as necessary. If not completely dry it may cause a strange smell.
Page 115: Desinfection
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. This works against bacteria and mold, but not as a sterilizing agent.
