• 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 “ Attention” 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 “ Attention” are also likely causing 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.
• 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
insufcient 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.
• Specic 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 lapping the wiring. Improper installation might
cause such accidents as heating or re accidents.
• While placing or reinstalling the air conditioner, except the specic 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 specic 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.
1.9.2 Safety

254
• 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.
• The air conditioner should be effectively 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.
• when the water discharge hole be blocked or the lter becomes dirty, there maybe leads to condensing water
drop down, and at the same time there maybe some drops of water spit out.
• In case of ambient dew point temperature greater than 28 degrees Celsius or humidity greater than 80%, there
maybe cause condensation drops or blow out, electrical or moisture sensitive items shouldn't be put below.

255
Items with this warning sign concerning the product's safety and the personal security must be
performed strictly.
Items with this forbidding sign refer to absolutely forbidden behaviors. If not, they may cause
machine damage or endanger operator's personal safety.
Clean the lter regularly.
Cooling or heating performance will be degraded
if the lter is blocked, resulting in large power
consumption, failure, and water dripping
at freezing.
Don't touch the outlet while the ap is moving. Don't
put anything in the grid in case danger may occur.
Avoid cold wind from blowing out.
During heating running, the fan of indoor units will
not rotate immediately as to prevent cold wind from
blowing out.
Changing Wind Speeds:
In the state of refrigerating, with automatic blowing
mode, the wind speed automatically decreases when
the room temperature approaches the setting.
In the state of heating, when the room temperature
reaches the setting temperature the compressor
stops working and the fan turns to low wind or
stops. Wind speed changes automatically in the
dehumidifying mode.
Regulating Wind Direction:
It is recommended not to make the wind deector
downwards for a long time to avoid condensation at
air outlet port during refrigerating or dehumidifying.
Water dropping might appear at the air outlet port in
refrigerating or dehumidifying mode.
Defrosting:
During heating running, the air conditioner would
defrost automatically if there is frost on heat
exchanger of outdoor units.
Do not rotate fans of both indoor units and outdoor
units during defrosting.
After nishing defrosting, the air conditioner will
resume running automatically.
The machine operation must be controlled by the
control.
Hints:
As air conditioners absorb heat from the environment
and release it to the room, heating effects will be
inuenced by the temperature in and out of the room.
