  3. Ceiling Cassette 1. Ceiling Cassette FDT Installation 1-1. Selection of Unit Location 1-2. Suspension Bolt 1-3. Temperature & Velocity Distribution 1-4. Duct Connecting 1-5. Drain Pump

  4. 1. Selection ofUnit Location Space for installation & service Model FDT71VD 100VD 125VD 140VD 4000mm to 5000mm or more 1000mm or more 2500mm or more 1000mm or more Obstacle Floor

  5. Case 1 : Location of FDT & Lighting !

  6. Case 2 : Indoor unit (FDTA140HKXE4) Conference room ceiling Layout of FDT ! Air distribution & temperature distribution !

  7. Case 3 : Indoor unit (FDTA140HKXE4) Height Air distribution & temperature distribution ! Air filter cleaning & maintenance !

  8. Case 4 : Indoor unit (FDTA71HKXE4) Height Air distribution & temperature distribution ! Q: What model is the most suitable for this room ?

  9. Case 5 : Height Height Air flow draft & fan noise !

  10. 2. Suspension Bolt 778 778

  11. 2. Suspension Bolt (1) OK NG Gap

  12. (2) Hang the indoor unit on the suspension boltsand fix it with double nuts by leaving 5cm margin of suspension bolt below fixing point. Distance from Indoor unit to the ceiling ≧30mm Fixed with singlenut Fixed with double nuts Leaving 5cm margin of suspension bolt

  13. (3) The indoor unit should be installed horizontally; Bad Examples: If the indoor unit is not horizontally installed, it may causeoverflow of drainage due to blocking or stagnating, and it looks bad. 81

  14. (4) When a suspension bolt is longer than 1.5m, reinforcement is required. 87

  15. 3. Temperature & Velocity Distribution

  16. Case 6 : Q: What is the issue & what is your countermeasure ?

  17. 4. Duct Connecting

  18. Case 7 : Fresh air ? Air supply duct Air supply ( 4 location) Outdoor air intake Indoor unit ( 1 corner ) (FDTA71HKXE4) Duct connection for air intake & air supply is different location

  19. 5. Drain Pump

  20. Ceiling Cassette : FDT Installation workability 2. Easy checking of drain pan Easy checking of drain pan condition by removing corner lid only 1. Arrangement of installation balance of indoor unit Checking from access ports with detachable covers at each corner without removing a panel 3. Joint stopper Workability is improved by applying temporally joint stopper for panel.

  21. Q: What should be checked for FDT installation ? 1. Location of FDT in the room ------ Basically supply air path & return air path should be clear of obstructions ------ 2. Height of the ceiling where FDT are installed ------ Check the height from the floor to the FDT ------ 3. Air flow velocity & temperature distribution of FDT ------ Check if the FDT air flow can cover all of the room -----

  34. Case 8 : Air return Indoor unit (FDUMA90HKXE4) Air supply duct Q: What is the issue & what is your countermeasure ?

  35. Case 9 : Air return Indoor unit (FDUA280HKXE4) Air supply duct Control box Q: What is the issue & what is your countermeasure ?

  36. Case 10 : Residence Indoor unit Concrete Ceiling (FDUMA71HKXE4) Cut & shave off the concrete for installation because of the low ceiling height Checking for the drawing at early stage is essential

  37. Case 11 : Office Glass will be installed to the every floor Air outlet duct Air outlet grill Stair well From the early stage building design & installation design is harmonized

  38. 5. Drain Pump

  39. 6. External Static Pressure

  40. Installation design & work Make sure the following (1) Space for installation ----- whether there is enough space surrounding the unit ----- ----- space in horizontal & vertical for the unit ----- (2) Space for service ----- check the service space for each of the unit ----- (3) Partition of the room ----- whether the room partition(wall) is different or not from the original installation design of the units ----- Sometimes configuration of the room and building are suddenly changed by the contractor or the investor without any notice to the consultant or the distributer of air-conditioner. Then it is better to get those information as much as possible for avoiding the trouble what comes from those changes.

  41. Q: What should be checked ? 1. Whether design change of the room is exist or not from the original installation plan ---- Room partition & duct route ---- 2. Space for service ----- After service & maintenance work ---

  42. Duct connected 1. Air flow duct & configuration 1-1. Supply air duct 1-2. Return air duct 1-3. Air flow duct resistance
