MCAC-UTSM-2008-04 Features
Indoor units 7
1. Features
1. Consumes up to 30% less energy than non-inverter units
——DC inverter compressor
——indoor fan motor adopts DC motor
2. Achieves set temperature more quickly
——air supplying from top and bottom or from top only
——air inlet from four directions
3. Compact unit body, space saving
——this unit body is very thin and harmonious with room. It is beautiful, elegant and space saving.
——lightweight and compact.
4. Flexible installation.
——can be used for floor standing or lower wall applications
——as a floor standing floor model, it can be semi or fully recessed without loss of capacity.
5. High efficiency filter
——built in Formaldehyde nemesis filter
——active-carbon and biological anti-virus filter is optional.
6. Comfort
——flexible air blow: vertical auto swing and wide angle louvers ensure that warm air reaches the furthest
corners of the room and increase the air flow coverage
——Low noise operation, lowest to 23Db
——Low starting power and precise room temperature adjustment
7. Powerful mode can be selected for rapid cooling or heating.
8. Easy cleaning grille and maintenance
9. Indoor unit adopts DC motor, it has five level fan speed meet different requirements.
