1.4 Product features
Universal outdoor unit
The outdoor unit can match with duct and cabinet type indoor unit.
High static pressure design for duct unit
The designed exterior static pressure can be adjusted from 0Pa~196Pa. The air outlet duct can be
selected freely, generally, there are two types as follow:
Duct unit: super thin unit body, no occupying the indoor space
The whole unit can be concealed in the building, without effect of the indoor décor.
With air inlet filter, enhance the air quality
The high efficiency filter can collect the dirt and remove the bacterium, which can be installed on the
easy-to-unload place, convenient to be cleaned.
Cabinet unit: newly designed luxurious LCD operation panel
On the front panel, you can find there is a luxurious operation panel. Just slightly pressing, the
comfort will come around you. Meanwhile, the unit is equipped with the advanced large angel remote
receiving technology.
Multiple control types
or( + )
The duct and cabinet unit can be controlled be the wired controller orby the infrared controller.The
cabinet type unit can be controlled with the infrared controller. If the unit is duct type and you want
infrared type, you need to add an infrared controller YR-H71.
And the infrared controller can be equipped with the controller holder, convenient to fix the
remote controller.

Convenient infrared remote controller
The newly designed infrared remote controller YR-H71 can be used for all indoor units of single type,
multi split type, and H-MRV type except for the cabinet unit. This controller can be compatible with all old
remote controllers except for that of cabinet units.
Auto–restart function (optional)
All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will
automatically recover the previous running mode once the power supply is on.
Self-diagnostic function
In the course of operation, if the failure occurs, the failure code will display on the wired controller or
on the operation panel. Then according to the failure code chart, you can eliminate the failure soon.
Central control function, if connected with a detector and a central
controller
24-hour timer (standard)
Changeover function
The unit can realize changeover function to enhance the reliability and the precision by connecting a
detector.

3. Safety precaution of indoor and outdoor
Carefully read the following information in order to operate the airconditioner correctly.
Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTION! 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.
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.
