2 FEATURES
2.1.
2.1.1.

New design
Gentle curved styling

3. Adoption of wing-shaped vanes

· The base has gentle curves which express a functional beauty. It spreads the air quietly over a wide area.

2.2.
2.2.1.

Such quietness!
Several new mechanism add up to low 49 dB noise (W50BT - High Fan Speed)

· The vanes of the fan have been changed to "aerodynamic" shaped vanes, so that the air flow more smoothly over the vane surfaces and noise is thus suppressed. · Side filters have been adopted in the pipe partitions. These allow the air intake space to be increased and also further reduce noise.

2.2.2.

Automatic swinging louvre

1. Delta throat fan A delta throat (projection) has been attached to the fan outlet to suppress the generation of vortexes. This helps maintain air flow speed even at lower fan speeds and is effective in reducing noise.

· The horizontal air flow angle is a wide 100 degrees (manual). The louvre can swing automatically (through 70 degrees vertically) using the remote control. This increases the area of comfortable air flow and warms the air even to floor level.

2. Reflux orifice The orifice at the intake port is equipped with an air flow guide which minimizes the flow disturbances which occur at the orifice and inside the impeller. This reduces pressure losses inside the casing and also helps reduce noise.

2.2.3.

Newly-shaped louvre

· The newly-shaped louvre and air outlet effectively distribute the air flow. During cooling, this stops warm air from collecting near the louvre, and prevents freezing.

2.3.1.

Easy installation
Easy suspension

2.5.
2.5.1.

Easy maintenance
Long life filter (standard equipment)

· A suspension bolt fixing bracket with 4-point support is attached to the main unit, which increases the space available for installation.

2.3.2.

Two installation methods : standard and wall

· In general office environments, cleaning (maintenance) is not required until after approximately 2,500 hours of operation, thus reducing maintenance work. · For optimum comfort, it is recommended to clean the air filter every 1-1/2 months.

· In addition to the standard (1) ceiling installation, a wall (2) installation method (using a wall-hanging bracket) is available for cases where the ceiling is too high for the main unit to be suspended.

2.5.2.

Maintenance is possible from underneath the unit.

2.4.
2.4.1.

Piping
3-direction pipe lead-out

· If the bottom panel is detached, the drain pan can then be removed and installed from underneath the unit, and inspection and servicing of component such as the control panel also becomes easier.

· The refrigerant piping can lead out in one of three directions (right, rear-right and top-right), and the drain pipe direction can be selected from four directions (right, rear-right, left and rear-left).

2.6.

Auto fan mode (indoor unit)

· Auto fan mode is added besides high, medium and low. It automatically adjusts the fan speed according to the indoor unit's temperature.

2.7.

Hot start system (heat pump models) Automatic changeover function (heat pump models)

2.8.

· The unit automatically switches between cooling and heating in accordance with operating load in order to maintain a comfortable indoor temperature.

Low-noise outdoor units

2.9.1.

Product features

· Low-noise design improves comfort in surrounding areas 1. The noise-suppressing winglet fan is a result of new research into vane design theory. The unique curved shape suppresses the generation of vortexes, thus reducing air flow noise. 2. The adoption of double-orifice rings reduces air passage resistance. 3. Strengthening of the noise insulation materials in the compressor and the sealing-in of mechanical noise allows vibration noise to be greatly enclosed and suppressed. 4. The heat exchanger has an L-shaped design to allow air to flow more smoothly. 5. Noise is automatically reduced further during night-time operation with lower outdoor air temperatures.

2.10. Greatly improved workability increases system renewal capability

· Pipes that are one size larger can also be connected for renewal. - If renewing the system, existing refrigerant pipes can be utilized so that only the indoor and outdoor units need to be replaced. - For example, liquid and gas pipes from 10 years ago can be connected to current pipes with the same size or one size larger. Effective utilization of materials reduces working time and trouble. (Adaptor sockets are not supplied.)
