1.5 Product features

1.5.1 Outdoor unit .

Flexible and easy installation

The outdoor can meet the higher request of installation. From the specifications, you will find for

each unit, how long and how high the piping will be, which will be convenient for design and installation.

Optional safety devices and much more precision control device

a. Ambient temperature sensor, coil temperature sensor and compressor temperature sensor

make the temperature control and defrosting control more precise.

b. High/low pressure switch can feel the discharging pipe pressure and suction pipe pressure on

time and precisely. If the pressure is too low or too high, it will stop the compressor to prevent it

being damaged for the sake of pressure.

c. 3 minutes delay protection for the compressor, the device can protect the compressor from

some damages and make the compressor have a long life.

Silent operation

New design of long piping length and large drop

1.5.2 Decent convertible indoor unit

Optional installation mode

The indoor unit can be installed on the floor or to the ceiling, it is determined by the host favor and

the room décor. It is more convenient to service and installation.

Silent operation

The convertible unit is equipped with a high efficient, smooth, multi-blade centrifugal fan, which

generates a powerful but gentle airflow to any corner in the room.

Space-saving design

An innovative fan and the ultra thin heat exchanger result in the ultra thin convertible unit. Fully

adjustable mounting brackets make it possible to install the unit enven in the tightest places. Less than

199mm (for HDU-18) of vertical direction are required for installation.

Large angle air supplying

I00º wide angle louvers and 70º wide angle blades design to make a precise control of the airflow,

it equably distributes the comfortable air to every coner of the room

Automatically control of airflow direction for fast temperature adjusting

Central control function, if connected with a central controller
