(1) Low operation noise, quiet design for user comfort

---Streamline plate ensures quietness

---Creates natural and comfortable environment

(2) Efficient cooling

---Equal, fast and wide—range cooling

(3) The adoption of the most advanced 3-dimensional centrifugal fan

---Reduces the air resistance passing through and operating sound.

---Smooths air flow

---Makes air speed distribution to the heat exchange uniform.

(4) Improvement for easy installation and maintenance

---Little space is required for installation into a shallow ceiling,

---Extremely compact casing (22-7/16in (570mm) in width and depth) enables unit to fit flush into ceilings and match standard architectural modules

---Because of the compactness and weight reduction of the main unit and panel, all models can be

installed without a hoist.

(5) 360°Air Flow Panel

---360

air outlet makes equal, fast and wide range cooling

(6)Optimal design, smaller Control Box, Space saving and convenient for wiring,

Using fire resistance galvanized steel for E-box material. Metal box makes the control part more stable and prevents damaging

(7) Drain up pump with 19-11/16 in. (500mm) lift fitted as standard, max. up to 23-5/8 in (600mm) head which can be customized.

(7) Adopting DC fan motor.

(7.1)Efficiency can be up to 90%. Contrast with the AC fan motor, the power consumption of DC fan motor can reduce up to 30%.

(7.2)The motor adopts fully enclosed structure design. The motor bearing can operate 80,000 hours continuously and easy for maintenance.

(7.3)Thanks to the DC fan motor, this wall-mounted indoor unit can meet the latest CE certification requirements.
