1. INFORMATION
1.1 1.5kW-indoor units connection
(1) 1.5kW-Indoor unit
Model
FDK15KXZE1
(2) Connectable KX6 outdoor units
FDC224-335KXE6 / service code A and there after
FDC400-1360KXE6 / service code F and there after
.FDC112-155KXE6, KXR and refresh KX series are not connectable.
.In case of connection with not the connectable outdoor units, error display (E22) will be appeared on the remote control.
(3) Installation limitation on 1.5kW-indoor unit connection
①KX6 outdoor unit must have total indoor unit connection capacity ratio of 100% or more.
<Example>
FDC680KXE6 / service code F connecting with one or more 1.5kW-indoor units must have total indoor unit capac-
ity 680 or more.
②Total piping length between outdoor unit and indoor units must be 150m or more, including both main and branch piping.
③󳡃When one or more 1.5kW-indoor units are in the system, outdoor temperature condition in the cooling operation must
be 10°C or more. Without 1.5kW-indoor units connection in the system, the outdoor lowest temperature for FDC112-
335KXE6 is -15°C and that for FDC400 - 1360KXE6 is -5°C.

But, wiring in the remote control case should be under 0.5mm2. Change the wire size outside of
the case according to wire connecting. Waterproof treatment is necessary at the wire connecting
section. Be careful about contact failure.

5. NOISE LEVEL
Notes(1) The data are based on the following conditions.
Ambient air temperature: Indoor unit 27℃WB. Outdoor unit 35℃DB.
(2) The data in the chart are measured in an anechoic room.
(3) The noise levels measured in the field are usually higher than the data because of reflection.
Measured based on JIS B 8616

6. TEMPERATURE AND VELOCITY DISTRIBUTION
Indoor temperature
Cooling 27°CDB/19°CWB, Heating 20°CDB
〔Note〕
These fi gures represent the typical main range of temperature and velocity distribution at the center of air outlet within the published conditions.
In the actual installation, they may differ from the typical fi gures under the infl uence of air temperature conditions, ceiling height, operation conditions and obstacles.
