8 Application Information Installation Guideline Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. Installation Diagram Indoor unit Front panel 30mm or more from ceiling Caulk pipe hole gap with putty. Cut thermal insulation pipe to an appropriate length and wrap it with tape, making sure that no gap is left in the insulation pipe s cut line. 50mm or more from walls (on both sides) Wrap the insulation pipe with the finishing tape from bottom to top. Air filter M4 x 12L Service lid Opening service lid Service lid is opening/closing type. Opening method 1) Remove the service lid screws. 2) Pull out the service lid diagonally down in the direction of the arrow. 3) Pull down. Outdoor Unit 6

9 Application Information Outdoor Clearance If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area), sulphide gas (near hot spring, oil refinery plant), such as substances may lead to failure of the unit. Where a wall or order obstacle is in the path of outdoor unit s intake or exhaust airfl ow, follow the installation guidelines below. For any of the below installation patterns, the wall height on the exhaust side should be 1200mm or less. Model: RK25/35FXV19, RXN25/35FXV1 Wall facing one side More than 50 More than 100 Wall facing two side 1200 or less More than 100 More than 150 More than 50 More than 50 Side View Top View Wall facing three side More than 150 More than 50 More than 300 Top View Model: RK50/60CXV19, RXN50/60CXV1 Unit : mm A B C D OBSTACLE AIR INLET AIR DISCHARGE OBSTACLE OBSTACLE AIR INLET SERVICE SPACE OBSTACLE ALL MODELS A B C D Minimum Distance 300 mm 1000 mm 300 mm 500 mm 7

11 Application Information Refrigerant Piping Piping Length and Elevation When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant fl ow increases, thus lowering the cooling capacity, and as the result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below: Indoor Unit Outdoor Unit L E Model Indoor (FTXN/FTK) Outdoor (RXN/RK) Min. Allowable Length (L), m 3 3 Max. Allowable Length (L), m Max. Allowable Elevation (E), m Gas Pipe Size, mm/(in) 9.52 (3/8") (1/2") (5/8") Liquid Pipe Size, mm/(in) 6.35 (1/4") 6.35 (1/4") Additional Charge The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.5m, additional charge of the refrigerant after vacuuming is not necessary. When the piping length is more than 7.5m, additional refrigerant charge (g) per additional 1m length as tabulated: Indoor (FTXN/FTK) Model Outdoor (RXN/RK) Additional charge [g/m] Example: FTXN25 & RXN25 with 12m piping length, additional piping length is 4.5m. Thus, Additional charge = 4.5[m] x 20[g/m] = 90.0[g] 9
