1. Features
1.1 Flexibility in duct design
1.1.1 External static pressure of Indoor Unit can be up to 280 Pa, which allows for extensive duct work and
therefore more flexibility. Challenges such as high ceilings can be overcome and cool air delivered to every
corner of a room.
1.1.2 With 420mm (models 71~160) thick body, the minimum distance above the ceiling is 450mm.
1.2 Wide capacity range
The capacity ranges from 7.1kW to 28.0kW, totally 9 models.

Adoption of a DC fan motor can raise efficiency up to 90%. When compared with anAC fan motor, power
consumption can be reduced by up to 30% with a DC fan motor.
Thanks to the DC fan motor, this high static pressure duct indoor unit can meet the latest CE certification
requirements.
1.4 Convenient installation
1.4.1 The EXV is fixed inside the indoor unit (for 71~160 model), no extra connections required.
1.4.2 Standard filter with aluminum frame, which is removable from the bottom in a downward direction.
1.4.3 Air plenum is included as standard equipment.
1.4.4 Flange for air in/outlet duct connection comes standard.
1.4.5 Optional drain pump (for models 71~160).
Drain pump is equipped as an optional accessory with a 750 mm pump head.
1.4.6 Easy motor and maintenance access. The conveniently designed access method means the motor
can be replaced without removal of the unit.
1.4.7 Integrated electrical control box structure for convenient maintenance and installation.
1.5 Flexible control and convenient maintenance
1.5.1 Standard wired controller KJR-29B1/BK-E, and wireless remote controller RM05/BG(T)E-A is
offered as an option.
1.5.2A new display board is used in the indoor unit to collect information from the control boards.
Malfunction codes and running state can display on the board.
1.5.3 Standard functional ports such as remote On/Off dry contact are provided.

Notes:
1. Nominal cooling capacities are based on the following conditions: return air temperature: 27°CDB, 19°CWB, outdoor air
temperature:35°CDB,equivalent ref. piping: 8m(horizontal)
2. Nominal heating capacities are based on the following conditions: return air temperature: 20°CDB,outdoor air temperature:
7°CDB,6°CWB,equivalent ref. piping: 8m(horizontal)
3. *( ) is the available static pressure range which represents optimal pressure levels at which the unit can operate stably.
When selecting a suitable unit please refer to the recommended static pressure level ranges in the installation manual. Risks
of selecting a unit outside of the optimal range include higher noise levels, low air flow volume ect.
The value without ( ) is rated static pressure.
