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 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.
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. lf not, accidents such as electric shocks may
happen. The installed air conditioner should be checked for electricity leakage by being powered.
lf the ambient humidity bigger than 80%, when the water discharge hole be blocked or the lter becomes
dirty, or airow speed change, there maybe leads to condensing water drop down, and at the same time
there maybe some drops of water spit out.
Attention
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 insu󰀩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 lipping 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.
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. ln
addition, heat preservation should be taken to avoid condensation. lmproper 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.

Symptoms Reasons
All these are not problems
Water ow sound
Water flow sound can be heard when starting operation, during
operation or immediately after stopping operation. When it
starts to work for 2-3 minutes, the sound may become louder,
which is the owing sound of refrigerant or the draining sound of
condensed water.
Cracking sound During operation, the air conditioner may make the cracking sound, which is caused from the temperature changes or the
slight dilation of heat exchanger.
Terrible smell in
outlet air The terrible smell, caused from walls, carpet, furniture, clothing, cigarette and cosmetics, attaches on the conditioner.
Flashing operating
indicator When switching it on again after power failure, turn on the manual power switch and the operating indicator ashes.
Awaiting indication
It displays the awaiting indication as it fails to perform refrigerating
operation while other indoor units are in heating operation. When
the operator set it to the refrigerating or heating mode and the
operation is opposite to the setting, it displays the awaiting indication.
Sound in shutdown
indoor unit or white
steam or cold air
To prevent oil and refrigerant from blocking the shutdown indoor
units, refrigerant ows in the short time and make the sounds of
refrigerant owing. Otherwise, when other indoor units performs
heating operation, white steam may occur; during refrigerating
operation, cold air may appear.
Clicking sound
when switching the
air condition on
When the conditioner is powered on, the sound is made due to
the resetting of the expansion valve.
Please make another check.
Start or stop working
automatically Check if it is in the state of Timer-ON and Timer-OFF.
Failure to work Check if there is a power failure.
Check if the manual power switch is turned o󰀨.
Check if the supply fuse and breaker are disconnected.
Check if the protective unit is working.
Check if refrigerating and heating functions are selected
simultaneously with the awaiting indication on line control.
Bad cooling &
heating e󰀨ects
Check if air intake port and air outlet port of outdoor units are
blocked.
Check if the door and windows are open.
Check if the ltering screen of air cleaner is blocked with sludge
