conditioner can't be installed on the grids such as the non-special metal burglar-proof net. The place with insufcient
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

Outdoor units are of parallel connection via three lines with polarity. The main unit, central control and all indoor units are
of parallel connection via two lines without polarity.
There are three connecting ways between line control and indoor units:
A. One line control controls multiple units, i.e. 2-16 indoor units, as shown in the above gure, (1-5 indoor units). The
indoor unit 5 is the line-controlled main unit and others are the ine-controlled sub units. The remoter control and the
main unit (directly connected to the indoor unit of line control) are connected via three lines with polarity. Other indoor
units and the main unit are connected via two lines with polarity.SW01 on the main unit of line control is set to 0 while
SW01 on other sub units of line control are set to 1, 2, 3 and so on in turn. (Please refer to the code setting at page 17)
B. One line control controls one indoor unit, as shown in the above gure(indoor unit 6-19). The indoor unit and the line
control are connected via three lines with polarity.
C. Two line controls control one indoor unit, as shown in the gure (indoor unit 20). Either of the line controls can be set to
be the master line control while the other is set to be the auxiliary line control. The master line control and indoor units,
and the master and auxiliary line controls are connected via three lines with polarity.
When the indoor units are controlled by the remote control, switch over the modes by Switching Mode of LineControlled Main Unit/ Line-Controlled Sub Units/ Remote-Controlled Types. The signal terminals needn't to be
equipped with wires and connected to the line control.
