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

gases because the inflammable gases
near to air-conditioner may cause fire
hazard.
Connect earthing wire.
Use discharge pipe correctly to ensure
efficient discharge.
Earthing wire should not be con-
nected to the gas pipe, water pipe,
lightning rod or phone line, in-correct
earthing may cause shock.
Incorrect pipe use may cause water
leaking.

WARNING!
Installed electrical-leaking circuit
breaker.
It easily cause electrical shock without
circuit breaker.
Please let the dealer be responsible for
installing the conditioner.
Incorrect installation may cause water
leak, electrical shock and fire hazard.
Call the dealer to take measures to
prevent the refrigerant from leaking.
If conditioner is installed in a small
room be sure to take every measure in
order to prevent suffocation accident
even in case of refrigerant leakage.
When conditioner is deinstalled or
reinstalleddealer should be responsible
for them.
