User Notice
◆The total capacity of the indoor units which runs at the same time can not
exceed 150% of that of the outdoor units; otherwise, the cooling (heating) effect of each
indoor unit would be poor.
◆Switch the main power on 8 hours before start the unit, helpful for a successful
startup.
◆It is a normal phenomenon that the indoor unit fan will still run for 20~70
seconds after the indoor unit receives the “stop” signal so as to make full use of
after-heat for the next operation.
◆When the running modes of the indoor and outdoor units conflict, it will be
indicated on the display of the wired controller in five seconds and then the indoor unit
will stop. In this case, they can back to the normal condition by harmonizing their
running modes: the cooling mode is compatible with the dehumidifying mode and the
fan mode can go with any other mode. If the supply power fails when the unit is running,
then the indoor unit will send the “start” signal to the outdoor unit three minutes later
after power recovery.
◆During installation, the communication cable and the power cord must not be
twisted together but instead separated with an interval of at least 2cm; otherwise the
unit is likely to run abnormally.
◆This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the appliance
by a person responsible for their safety. Children should be supervised to ensure that
they do not play with the appliance.
◆If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
◆This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved. Children shall not play
with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.

◆If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
◆The appliance shall be installed in accordance with national wiring regulations.

Inflammable Refrigerant" for Space X.)

The Refrigerant
WARNING
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.
The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion
under certain conditions. But the flammability of the refrigerant is very low. It can
be ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R32
has got very good thermodynamic features which lead to a really high energy
efficiency. The units therefore need a less filling.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacture. Should repair be necessary, contact your nea-
rest authorized Service Centre. Any repairs carried out by unqualified personnel
may be dangerous. The appliance shall be stored in a room without continuously
operating ignition sources. (for example: open flames, an operating gas appliance
or an operating electric heater.) Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger
than Xm .(Please refer to table "a" in section of " Safety Operation of Inflammable
Refrigerant" for Space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s

damage.
Warning!
◆The installation should be committed to the appointed service center; otherwise
it all cause water leakage, electric shock or fire etc.
◆Please install the unit where is strong enough to withstand the weight of the unit;
otherwise, the unit would fall down and cause injury or death.
◆The drain pipe should be installed as instructed in the manual to guarantee the
proper drainage; meanwhile it should be insulated to prevent condensing; otherwise the
improper installation would cause water leakage and then wet the household wares in
the room.
◆Do not use or place any inflammable or explosive substance near the unit.
◆Under the occurrence of an error (like burning smell etc.), please cut off the main
power supply of the unit.
◆Keep good ventilation in the room to avoid oxygen deficit.
◆Never insert your finger or any other object into the air outlet/inlet grille.
◆Please take notice of the supporting frame of the unit to see if it is damaged over
the long time period of use.
◆Never refit the unit and contact the sales agent or the professional installation
personnel for the repair or relocation of the unit.
An all-pole disconnection switch having a contact separation of at least 3mm in all
poles should be connected in fixed wiring.
Caution!
◆Before installation, please check if the power supply corresponds with the

2
requirement specified on the nameplate and also check its security.
 ◆Before use, please check if the piping and wiring are correct to avoid water
leakage, refrigerant leakage, electric shock, fire etc.
 ◆The main power supply must be earthed to avoid the hazard of electric shock
and never connect this earth wire to the gas pipe, running water pipe, lightening rod or
phone cable’s earth lead.
 ◆Turn off the unit after it runs at least five minutes; otherwise its service life will be
shortened.
 ◆Do not allow children operate this unit.
 ◆Do not operate this unit with wet hands.
 ◆Cut off the main power supply prior to the cleaning of the unit or the replacement
of the air filter.
 ◆When the unit is not to be used for a long time, please cut off the main power
supply of the unit.
 ◆Do not expose the unit to the moist or corrosive circumstances.
 ◆After the electric installation, please take an electric leakage test.

Safety operation of flammable refrigerant
Qualification requirement for installation and maintenance man
All the work men who are engaging in the refrigeration system should bear the
valid certification awarded by the authoritative organization and the qualification
for dealing with the refrigeration system recognized by this industry. If it needs
other technician to maintain and repair the appliance, they should be supervised
by the person who bears the qualification for using the flammable refrigerant.
It can only be repaired by the method suggested by the equipment’s manufacturer.
Installation notes
The air conditioner is not allowed to use in a room that has running fire (such as fire
source, working coal gas ware, operating heater).
It is not allowed to drill hole or burn the connection pipe.
The air conditioner must be installed in a room that is larger than the minimum room
area. The minimum room area is shown on the nameplate or following table a.
Leak test is a must after installation.
