Note:
■ Working conditions for cooling: inlet air temperature - dry/wet bulb 27°C/19.5°C; temperature of inlet/outlet water - 5°C/15°C.
■ Working conditions for heating: inlet air temperature - dry bulb 21°C; inlet water temperature 60°C; water flow - equal to that for cooling
operation.
■ Rated air flow is measured under standard atmosphere using dry coils (dry bulb 20°C).
■ Sound pressure grade and sound level are measured in a semi-silent room as per GB/T 19232-2003.
■ H, M and L represent high, medium and low fan speed respectively.
■ Static pressure refers to outlet static pressure.
■ All performance parameters in the above table are measure with a power supply of 220V~/50Hz.
■ The right/left orientation of connection pipes are exchangeable on site (cooling/heating capacity needs to be multiplied by a correction factor
of 0.93 after exchange).

1.Compact Exterior

?

With a compact, graceful and robust design, this
super-thin unit can be concealed in a small space
inside the ceiling.

?

2.Low Noise


The unit features a forward-pitched low-speed centrifugal fan with wide impellers. The fan has a good
dynamic balance and a stable performance, and minimizes the operation sound while ensuring enough air
flow and the static pressure of outlet air by using efficient sound-dampening and heat-insulation material.

?

3.Efficient and Energy Saving
?

To maximize heat transfer and exchange efficiency, the unit features heat exchange coils made of quality
copper tubes, efficient hyperbolic aluminum shutter fins, precise mechanic tube expansion and a fan with
wide impellers and a high air supply capacity.

?

4.Easy and Flexible Installation
?

The unit features a symmetric design and can be easily installed. The left and right connection pipes are
exchangeable. For units with a return air plenum, the air return mode can be customized.

?

5.Safe and Leakage-proof
?

The condensate water collector are molded as a whole (no welding line or dots) and entirely coated with
fireproof material to prevent leakage. A specially designed pitch on the collector also helps ensure smooth
discharge of condensate water.

?

6.Easy Maintenance


The unit features a single-phase capacitive motor with a low operation sound and a long service life thanks
to a quality precision ball bear that is hermetic, fully lubricated, rustproof and durable. All wires leading out of
the motor are protected against damage using flexible metal tubes.
