Standard Situation/Conditions
C.Series brief introduction
1.comfortable:wide-angle airflow
The vertical dual-flap and horizontal wide-angle louvers ensure the cool(warm) air reaches every
corner of the room.
2.Health air purifying
An air purifying filter with deodorizing and disinfecting functions keeps the air clean and users
healthy.
3.Quiet operation
Fan With Random-pitched Blades.
Random-pitched blades help reduce operating noise while maintaining a high airflow rate.
4.Engergy efficient
The design of inner-grooved copper tube greatly increases the refrigerant contact area and the
efficiency of cooling/heating functions.
5.Convenience
Auto restart and washable panel:
The grille can be removed easily and washed when necessary.Any series have the function then
even if the power falls when the unit is operating unit will automatically return to the operating
settings in use before the power failure when power is restored.
6.Wide variety of functions
24-Hour Timer:
24-hour timer allows users to select the exact time they would like the air conditioner to turn on
and to turn off.Timers on previous models operation based on the number of hours of desired
operation.
7.Night-set models
When the air conditioner is operationg on the timer-off circuit.The preset room temperature
gradually rises(going down in heating)before the unit stops as shown delow.Users can sleep
comfortably without sudden change in temperature.
8.Program”dry”
This function automatically reduces the level of humidity while maintaining the preset indoor
temperature.
