3 1. GENERAL INFORMATION 1.1 Applications YEFB high pressure ducted fan coils are specifically designed for ducted installations, with external static pressure up to 250 Pa. Their high pressure fan decks permit to satisfy every request of heating and cooling application in big environments. 1.2 Operation The effectiveness of a fan coil is due to the large surface area of the finned heat exchanger (coil) where the air drawn from the room by the fan passes through. Heating operation: the hot water circulating in the finned coil supplies heat to the air passing through the heat exchanger. Cooling operation: the chilled water circulating in the finned coil removes heat from the air passing through the heat exchanger. The air is also dehumidified and the condensed water vapor must be discharged from the unit: suitable drains must therefore be provided to drain the condensed water that collects in the condensate tray. 1.3 Performances The performance of a fan coil can vary greatly with changes in the temperature and in the amount of water circulating through the coil, as well as with changes in the temperature and in the amount of air circulating through the coil. The air volume is detered by selecting the proper fan speed (MIN-MED-MAX), while the water flow rate is detered by the specifications of the system and of the pump. Thermal performances of the unit can be optimized by controlling the inlet flow rate of the water with proper regulating valves (ON/OFF or modulating), which can be supplied as accessories and which are necessary in case of cooling operation. For each model, thermal performances in heating and cooling depend on the number of rows of the coil installed, which gives the opportunity to make the air treatment suit every condition required. In cooling function, under the same operating conditions, the more rows the heat exchanger has, the more it will dehumidify. 1.4 Product range The YEFB high pressure fan coil units are available in 6 sizes ( ) for concealed horizontal installation, in 2 and 4 pipe systems. 1.5 Selection software To facilitate choosing the correct size of a fan coil for any operating condition (including those differing from the standard ones), Johnson Controls offers a dedicated computer program for the selection, for each model, of the performances, which can be downloaded from the Johnson Controls official web site, on request. Installation and Operation instructions concerning the software for selection are given on its «Help on line». 2

5 3. COMPONENTS 3.1 Structure The structure is made of galvanized steel. A particular manufacturing process gives stiffness to the structure: in this way all risks of vibration (which causes unpleasant noise) are strongly reduced. All the inner elements that could be cooled are completely lined with a polyurethane foam layer, which is not only a thermal insulation material but also a good sound attenuator. Self-extinguishing grade in accordance to norms: Class 1 UNI 8457 UNI In order to facilitate all maintenance operations, the structure is divided in 3 separate and independent sections: Condensate tray Fan deck Air filter. The air intake and outlet are provided with a 21 mm flange for an easy connection to the air duct. The YEFB fan coils can be installed on the ceiling by using the four fixing brackets always supplied with every unit.

6 3.2 Coils For each unit size there are 2, 3 and 4 row coils available; for 4 pipe systems it is possible to install a 2 or 3 row coil. It is therefore possible to have a combination of imum 7 rows (4 row cooling + 3 row heating). For models 060 and 070 are also 5 row coils available which can be combined with additional 2 or 3 row coils. All coils consist of 3/8" external diameter copper pipes mechanically expanded to the aluum fin packs, provided with copper headers and brass soldering connections. Max. operating pressure 1,6 MPa, testing pressure 2,8 MPa. For the sizes 020, 030, 040 e 050 each header is provided with a very handy air valve, to allow air venting or water drainage from the coil. The air valve can be easily reached from the outside of the unit. For the sizes 060 and 070 the air vent valve are not present, therefore it is necessary to provide in the pipe connection a system for the water discharge and air venting of the coil. YEFB units can be ordered with right (standard) or left water connections, so defined when facing the air outlet. If necessary, however the coils can be easily removed and reversed on site. Water connections are 1/2" F (female threaded) for sizes 020, 030, 040, 050 1" M (male threaded) for size 060 and Fan deck The fan deck is composed by a 3 speed motor and 2 centrifugal galvanized steel scrolls. The motor and the scrolls are fixed on a rigid galvanized steel 1,5 mm thick basement. All motors are provided with permanently connected capacitor and thermal protection of the windings with automatic recharge; single phase 50/60 Hz for size 020 and single phase 50 Hz for sizes 030, 040, 050, 060 and 070. For all sizes the power supply is 230V± 10%. Each fan assembly is dynamically balanced, to reduce noise and wear of the components to imum levels; it can easily be removed for maintenance operation. 5

7 3.4 Condensate tray The condensate tray is made of galvanized steel and it is completely insulated by a 12 mm thick closed cell polyurethane foam layer. The condensed water is discharged from both sides (left or right) through a 20 mm diameter header. 3.5 Air filter The air filter consists of a washable polyester acrylic fiber, filtration class G3. A filter with higher filtering grade (G4 or F5) is also available upon request for each model. The particular pleated shape of the filter, protected by a metal frame, allows to have a big filtering surface with only 45 mm thickness. The filter section can be easily removed for cleaning and maintenance operation. 3.6 Standard electrical panel IP30 All models are provided with a teral board with screw terals contained in a self extinguishing ABS plastic box (IP30). For sizes a supporting relay is installed as standard on the electrical panel, where the power supply must be connected. The electric box must be fixed on the pre-arranged position on the side of the YEFB unit and connected with a «plug and play» system to the plug already present on the side itself. Every YEFB model is supplied with an electric wiring diagram showing all the electrical components, accessories factory fitted and/or remote controllers ordered together with the unit. Everything must be correctly wired in accordance to the diagram, to obtain the requested working conditions of the unit Electrical panel IP55 (optional) Electrical panel composed by a teral board with screw terals contained in a high protection box (IP55). Available on request. 3.7 Packing Every unit is packed in a carton box and lays on a wooden pallet.
