1. Features
(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
---3600air 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
preventsdamaging
(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.

4. Service Spaces
1) There is enough room for installation and maintenance.
2) The ceiling is horizontal, and its structure can endure the weight of the indoor unit.
3) The outlet and the inlet are not impeded, and the influence of external air is the least.
4) The air flow can reach throughout the room.
5) The connecting pipe and drainpipe could be extracted out easily.
6) There is no direct radiation from heaters.
Unit：in(mm)
Keep more than 7.55ft (2.3m) distance between the panel and ground of the room.
Keep at least 3.28ft (1m) to the wall of each side.
