1.4 Product features
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.
High efficiency filter
The unit adopts G3 grade filter, can efficiently filter the dirt etc, and improve the room air quality, at
the same time, the filter can pull out from downside, convenient for maintenance and cleaning.
Multi-mode for installation
The indoor unit can be installed with or without an air return duct according to the installation need.
Free setting of air discharging duct
The number of the airflow outlet and its installation position can be freely selected according to the
environment of the room, sufficiently considering the load of the room and the uniform temperature of the
room to realize more perfect comfort.
High esp design
Max. external static pressure of 196 Pa brings the quick temperature adjustment to the room.
Adopts high pressure fan to provide quich speed of air blowing while keeping a low sound level and
ensuring a good air circulation of the whole indoor space.
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.
Group control and Central control if connected with with a group
controller or a central controller
Weekly timing function, if connected with a weekly timer YCS-A001

3. Safety precaution
Carefully read the following information in order to operate the airconditioner correctly.
Below are listed three kinds of Safety Cautions and Suggestions.
WARNING! Incorrect operations may result in severe consequences of death or serious injuries.
CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may
cause serious consequences.
IN TRUCTION : These information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The afety 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.
The 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.
