General Information 5
4. Features
4.1 Universal outdoor unit design
Indoor unit with the same capacity can match with the same outdoor unit.
4.2 High efficiency and energy saving.
Thanks to the DC inverter technology and optimized piping system, the EER of whole series can
easily reach A-class.
4.3 Low noise and low starting current.
Thanks to the DC inverter technology, the system can work with low noise, and very small starting
current.
4.4 Intelligent refrigerant adjustment technology（except 12000Btu/h）
Throttle part is made up of capillary and electronic expansion valve (EXV). The outdoor unit can
output the most accurate capacity in any condition.
4.5 Working in cooling mode under -15℃（except 12000Btu/h）
Outdoor unit built-in with low ambient kit, it can control the outdoor unit’s fan and cooling can be
performed throughout the year for computer rooms, banquet halls, etc. Wide operation range
covers outdoor temperatures as low as -15℃for cooling.
4.6 Convenient installation
--Adopt Quick Connector. The copper pipe connecting the indoor and the outdoor unit is delivered
already connected to the indoor unit. At the other end of the pipe is attached the male part of the
Quick Connector while the female part of the Quick Connector is fixed to the outdoor unit. So it’s easy
to installation.
4.7 Diversiform and universal controller for DC inverter air conditioners, including wireless remote
controller, wired controller (weekly timer, central controller, network controller for 18000Btu/h).

MCAC-UTSM-2008-05 Features
Ceiling and Floor Type 7
1. Features
1.1. New design, more modern and elegant appearance.
1.2. Convenient installation
--The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow
--It is especially useful when installation of an air conditioner in the center of the ceiling is impossible
due to a structure such as one lighting
1.3. Two direction auto swing (vertical & horizontal) and wide angle air flow
--Air flow directional control minimizes the air resistance and produces wilder air flow to vertical
direction.
--The range of horizontal air discharge is widened which secures wider air flow distribution to provide
more comfortable air circulation no matter where the unit is set up
1.4. Three level fan speed, more humanism design, meets different air-supply requirement.
1.5. Water proof by utilizing the absorbing plastic film on water collector
1.6. Easy operation. Auto-restart function, remote control and optional wire control method.
1.7. Low noise level plus compact size
--Shape of the blades has been improved to prevent noise caused by turbulence.
