•  If the air conditioner is transferred to a new user, this manual shall be transferred to the user, together with the 
conditioner.
•  Before installation, be sure to read Safety Considerations in this manual for proper installation.
•  The safety considerations stated below is divided into "
WARNING" and "  CAUTION". The matters on severe 
accidents caused from wrong installation, which is likely to lead to death or serious injury, are listed in " WARNING". 
However, the matters listed in "  CAUTION" are also likely cause the severe accidents. In general, both of them are 
the important items related to the security, which should be strictly abided by.
•  After the installation, perform test run to make sure everything is in normal conditions, and then operate and maintain 
the air conditioner in accordance with the User Manual. The User Manual should be delivered to the user for proper 
keeping.
  WARNING
•  Please ask the special maintenance station for installation and repair. Water leakage, electric shocks or re accidents 
might be caused from improper installation if you conduct the installation by your own.
•  The installation should be conducted properly according to this manual. Water leakage, electric shocks or re accidents 
might be caused from improper installation.
•  Please make sure to install the air conditioner on the place where can bear the weight of the air conditioner. The air 
conditioner can't be installed on the grids such as the non-special metal burglar-proof net. The place with insucient 
support strength might cause the dropdown of the machine, which may lead to personal injuries. 
•  The installation should be ensured against typhoons and earthquakes, etc. The installation unconformable to the 
requirements will lead to accidents due to the turnover of the machine.
•  Specic cables should be used for reliable connections of the wirings. Please x the terminal connections reliably to 
avoid the outside force applied on the cables from being impressed on the cables. Improper connections and xings 
might lead to such accidents as heating or re accidents.
•  Correct shapes of wirings should be kept while the embossed shape is not allowed. The wirings should be reliably 
connected to avoid the cover and the plate of the electrical cabinet lipping the wiring. Improper installation might cause 
such accidents as heating or re accidents.
•  While placing or reinstalling the air conditioner, except the specic refrigerant (R410A), don't let the air go into the 
refrigeration cycle system. The air in the refrigeration cycle system might lead to the cracking or personal injuries due to 
abnormal high pressure of the refrigeration cycle system.
•  During installation, please use the accompanied spare parts or specic parts. If not, water leakage, electric shocks, re 
accidents or refrigerant leakage might be caused.
•  Don't drain the water from the drainpipe to the waterspout where may exist harmful gases such as sulfureted gas to 
avoid the harmful gases entering into the room.
•  During installation, if refrigerant leakage occurs, ventilation measures should be taken, for the refrigerant gas might 
generate harmful gases upon contacting the ame.
•  After installation, check if any refrigerant leakage exists. If the refrigerant gas leaks in the room, such things as air 
blowing heaters and stoves, etc. may generate harmful gases.
•  Don't install the air conditioner at the places where the ammable gases may leak. In case the gas leakage occurs 
around the machine, such accidents as re disasters may be caused.
•  The drainpipe should be properly mounted according to this manual as to ensure the smooth drainage. In addition, heat 
preservation should be taken to avoid condensation. Improper drainpipe mounting might cause water leakage, which 
will get the articles at home wet.
•  The refrigerant gas pipe and liquid pipe should be heat insulated to preserve heat. For inappropriate heat insulation, the 
water caused from the condensation will drop to get the article at home wet.
Safety
•  The air conditioner should be eectively grounded. Electric shocks may occur if the air conditioner is ungrounded or 
inappropriately grounded. The wire for earthing shouldn't be connected to the connections on the gas pipe, water pipe, 
lightning rod or telephone.
•  The breaker for electricity leakage should be mounted. If not, accidents such as electric shocks may happen.
•  The installed air conditioner should be checked for electricity leakage by being powered.
•  If the ambient humidity bigger than 80%, when the water discharge hole be blocked or the lter becomes dirty, or airow 
speed change, there maybe leads to condensing water drop down, and at the same time there maybe  some drops of 
water spit out.
