NOTES 1. Location of nameplate: The unit nameplate is located on the control box cover. The decoration panel nameplate is located on the piping-side panel frame, under the corner cover. 2. When installing optional accessories, refer to their respective documentation. 3. Make sure the distance between the ceiling and the cassette does not exceed ·35·mm. The maximum ceiling opening is ·910·mm. 4. When the conditions in the ceiling exceed 30°C ambient temperature and 80% relative humidity, or when fresh air is inducted into the ceiling, additional insulation is required (polyethylene foam, thickness ≥·10·mm). 5. When installing a sensor kit, there will be a sensor on this location. For details, see the drawing of the sensor kit. 6. When installing a wireless controller, there will be a receiver on this location. For details, see the drawing of the wireless controller.

When installing a fresh air intake kit, provide a service access panel. 2. Field construction 3. This corner discharge outlet needs to be closed. 4. When installing a duct fan, use a wiring adapter to link the duct fan to the fan of the indoor unit. 5. The intake air flow rate is recommended to be ≤20% of the air flow rate at high fan speed. If the intake air flow rate is too large, the operating sound may increase, and the detection of the indoor unit suction temperature may be affected. 6. This indicates the distance between the T-joint inlet and the indoor unit inlet when the T-tube is connected. 328 328 427 427 448 508 840 840 55 55 A 1 2 3 4 5 6 0 140 130 120 110 100 90 80 70 60 50 40 30 20 10 725 (1000) 455 O148 180 278 AA O148 AB 320 222 455 3D121741D FXFN-B FRESH AIR INLET KIT Minimal installation height AA AB Model 277 319 FCAG35/50/60/71BVEB FXFQ20/25/32/40/50/63BVEB FXFA20/25/32/40/50/63A2VEB 319 361 FCAG100/125/140BVEB FXFQ80/100BVEB FXFA80/100A2VEB FXFN50/71A2VEB 361 403 FCAHG71/100/125/140HVEB FXFQ125BVEB FXFA125A2VEB FXFN112A2VEB FXFN80B2VEB ARROW VIEW C View ·A· Duct Piping side Drain side See note ·3· Inlet T-joint Designer decoration panel Decoration panel Suction chamber Suction chamber Field supply See note ·6· Ceiling opening Ceiling opening Air flow rate [m³/min] Static pressure in chamber [Pa] See note ·3· Service access panel ·450 x 450 mm· or more Duct Left side Right side See note ·1·.
