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
