ULTRA SLIM NEW STYLISH DESIGN PROFILE
This unit is contemporary in design and match even the most up to date interior decor. The slim, (only 22 mm
for B-series and only 28 mm for A-series) and round profile front panel of this unit adds a touch of elegance
to every decor.
TURBO MIXED FLOW FAN
Innovative design of highly efficient turbo fan produces an even air circulation in all direction.
BUILT-IN HIGH HEAD DRAIN PUMP
The unit has a built-in high head drain pump (with 500 mm drain head) to provide and ensure smoothness
drainage of condensate water.
STRONG AND ROBUST
The unit is built from strong casing material and robust parts to ensure long lasting reliable service. The drain
pan is made from the POLYSTYRENE with a plastic coating on the surface to ensure no leaking and
condensation occur.
FRIENDLY SERVICEABILITY
The air filter, electrical parts, fan, fan motor and drain pump can all be inspected and replaced from the
bottom of the unit by simply removing the air intake grille. The POLYSTYRENE drain pan and the heat
exchanger coils can be removed from the unit easily by removing the front panel.
MICROCOMPUTER REMOTE CONTROLLER
The incorporated microprocessor offers more accurate control and with the following extra features:
•Fan motor speed can be set at high/medium/low or automatic.
•Timer on/off - the unit can be pre-set to switch on and off automatically.
•Electronic thermostat - room temperature is precisely controlled, resulting in energy saving and increase
comfort.
WIRELESS REMOTE CONTROLLER
The compact wireless remote controller makes it possible to operate the air conditioner anywhere within the
room.

All the data above are based on 26.7°C entering DB. To obtain data for different entering DB,
please use the formula below :
Sensible capacity (EDB) = Sensible capacity (26.7) + 1.23 x L/s x (1 - BPF) ( EDB - 26.7 ) / 1000
Where, BPF = Bypass factor
EDB = Entering dry bulb temperature, ° C
