1.4Product features
1.4.1 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
1.4.2 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

Carefully read the following information in order to operate the airconditioner correctly.
Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTI N! Incorrect operations may result in injuries or machine damages; in some cases may
cause serious consequences.
Incorrect operations may result in severe consequences of death or serious injuries.
INSTRUCTI NS: hese information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The Safety Cautions should be at hand so that they can be checked at any time when needed.
If the conditioner is transferred to the new user, this manual should be as well transferred to the new user.
WARNING!
If any abnormal phenomena is found
(e. g.smell of firing), please cut off the
power supply immediately, and contact
the dealer to find out the handling
method.
Don't dismantle the outlet of the
outdoor unit.
he exposure of fan is very dangerous
whichmay harm human beings.
switch
off
In such case, to continue using the
conditioner will damage the conditioner,
and may cause electrical shock or fire
hazard.
Incorrect maintenance and repairment
may cause water leak, electrical shock
and fire hazard.
When need maintenance and repairment,
call dealer to handle it.
After a long time use of air-conditioner
the base should be checked for any
damages.
If the damaged base is not repaired, the
unit may fall down and cause accidents.
