Otherwise, it may be a cause of failure. For Heat Recovery System, there is no restriction if installed without a main piping branch. NOTE: Main Piping Branch: Both of the pipes branched from Multi-kit are connected to a further Multi-kit.

8 PAGE: 8 / Improvement of Workability Piping connection work can be now done from the refrigerant piping outlet (bottom right side of the front cover) in addition to three directions (front, rear or bottom) from the bottom base. On-Site Installation Work Install the piping connection kit at a position lower than the piping connection of the outdoor unit. Side The refrigerant oil is stagnated to the unit stopped. It is recoended to provide a trap in the case of raft foundations, since the piping connection is located at a low position. Side View of Outdoor On-Site Installation Work Current Model Provide a trap. Side Oil Trap Min. 200 Oil Trap Min. 200 Oil Trap Min. 200 Pull out pipes from bottom base hole.

Newly Added A new piping outlet is provided on the lower right side of the front cover and so the piping connection kit can be installed at the lower position. This makes the installation of piping from multiple outdoor units easy and straightforward.

11 PAGE: 11 / General features and benefits of the SET FREE FSXN1E series 5.1 Line-Up for Various Needs The new standard type FSXN1E can provide 2 systems ( Heat Pump System and Heat Recovery System ), to be chosen depending on the purpose. Outdoor units are available with capacities ranging from 8 to 54HP, with a total 24 outdoor unit models for each system. A custom air conditioning environment can be created to satisfy specific building conditions. Selectable System from Heat Recovery System and Heat Pump System Used as Heat Recovery System Simultaneous cooling/heating operation is available. Coon Use for 2 Systems Used as Heat Pump System Cooling or heating operation is available. High Efficiency by Heat Recovery Easy Installation with Standard System Outdoor Outdoor CH Heating Cooling Heating Cooling Fan Cooling Fan Cooling Refrigerant Piping (3 Pipes) (, High/Low Pressure Gas, Low Pressure Gas) Refrigerant Piping (2 Pipes) (, High/Low Pressure Gas) NOTE: It is not possible to change the type of system after installation.

12 PAGE: 12 / Installation Flexibility For installation spaces such as a balcony or a floor where it is an external static pressure is required due to the existence of elements such as louvers or ducts, a DIP switch setting (No. 5 pin on DSW5 is ON ) has been newly adopted. < Installation Example for Air Outlet Duct Kit > Balcony Building Installation of outdoor units to each floor. < Case that Open Space is Louver > < Case that Open Space is Wall > Ceiling Wall Air Outlet Duct Kit (*) (Field-Supplied) Ceiling Wall Air Outlet Duct Kit (*) (Field-Supplied) Duct (Field-Supplied) The air flow direction can be changed to open space by using air outlet duct kit. The recoended air outlet duct kit (*) has flanged opening, which makes the field connection work possible. Louver Outdoor Wall Outdoor NOTES: 1. Pay attention to the following circumstance when designing the installation. If there is a short-circuit at the air outlet duct, operation range becomes limited due to increased high pressure in cooling operation or decreased low pressure in heating operation, which may lead to failure of unit. 2. (*): Air outlet duct kit is field-supplied. Refer to Technical Catalog for the dimensional drawing of the recoended air outlet duct kit.

13 6. General Specifications 6.1 General considerations PAGE: 13 / 47 1 The heating and cooling capacities indicated refer to the outdoor unit operating with the indoor units at 100% of their capacity, and are based on Standard EN Operating conditions Cooling Heating air inlet temperature DB 27.0 C 20.0 C WB 19.0 C Outdoor air inlet temperature DB 35.0 C 7.0 C WB 6.0 C DB: dry bulb; WB: wet bulb. Pipe length: 7.5 m; pipe height: 0 m 2 The sound pressure level was measured under the following conditions: a. 1 m from the surface of the unit s service cover and 1.5 m from floor level. b. The data indicated is based on cooling mode. In the case of heating mode, the sound pressure level increases from 1 to 2 db(a). c. The data indicated has been measured in an anechoic chamber, so the reflected sound must be taken into account for installation. 3 If the main refrigerant pipe specified in the table is not available at the installation location, select the size given in brackets. In this case, prepare a suitable reducer. 4 There are no other combinations of units than those specified in the tables. 5 The width indicated for the outdoor dimensions takes into account a specific distance of 20 between the outdoor units (18-54 HP for FSXN1E series, HP for FSXNH(E) series). 6 The ERR and COP have been calculated from outdoor input power only. 7 The ESEER (1) is the standard cooling seasonal efficiency. 8 The ESSER (2) is the cooling seasonal efficiency with optimized system operation according to the seasonal demand.

(Rain water is also discharged) Pay attention to the following: (1) Choose a place where good drainage is available, or provide a drain ditch. (2) Do not install the unit over walkways. Condensation water may fall on people. In case of installing the unit in such a place, provide the additional drain pan. (3) Do not use drain boss in cold areas. The drain water in the drain pipe may freeze, causing cracks at the drain pipe.

29 PAGE: 29 / CH Small-sized unit and less suspension bolts facilitate installation and handling. Model: CH-6.0N2, CH-10.0N2 Suspension Bolt (Field Supplied) M10 x 2 NEW H Specifications Connection Model Dimension Net Number W x D x H () Weight (kg) Total HP of s * CH-6.0N2 6HP > 1 ~ x 214 x CH-10.0N2 6.1HP - 10HP 1 ~ 8 D W * When multiple indoor units are connected to the same CH unit, they are controlled with same operation mode. NOTE When opening the flow refrigerant at Operation ON/OFF, Thermo ON/OFF, Defrost Operation and Operation Mode, refrigerant flow noise may be heard from CH. Therefore install the unit in a place such as behind a ceiling, so that the sound may not be heard in the room. Cautions for installation of CH 1. CH unit consists of an electronic expansion valve for changing over from the heating (cooling) operation to cooling (heating) operation. Be sure to provide the specific service access panel on the electrical box side. 2. Refrigerant flow noise may be heard from the CH unit when the electronic expansion valve in the CH unit is activated. Therefore install the CH unit in a place where refrigerant flow noise may not leak such as in a hallway Select ceiling material such as plaster board (thickness 9) which minimizes refrigerant flow noise. 3. Do not install the CH unit in a place near bedrooms or hospital rooms. 4. Take the necessary measures to prevent refrigerant liquid piping from being connected to the other unit by mistake.
