power cable.
Do not unplug the power supply
plug during operation.
Do not touch (operation) the
product with wet hands.
Do not place a heater or other
appliance near the power cable.
Do not allow water to run into
electric parts. It may cause fire,
failure of the product, or electric
shock.
Do not store or use flammable gas
or combustible near the product.
Ensure that the condensing unit
has proper ventilation. Do not use
the product in a tightly closed
space for a long time.
If smoke is detected during the
operation of the unit, discontinue
use immediately. Turn the breaker
off or disconnect the power supply
cable.
Do not open the inlet grill of the
product during operation. (Do not

(flooded or submerged),
discontinue use immediately,
disconnect the power supply and
contact an authorized repair
technician or installer.
Turn the main power off when
cleaning or maintaining the product.
When the product is not be used
for a long time, disconnect the
power supply or turn off the
breaker.
CAUTION
Always check for gas (refrigerant)
leakage after installation or repair
of product.
Low refrigerant levels may cause
failure of product.
Install the drain hose to ensure
that water is drained away properly.
A bad connection may cause water
leakage.
Keep the product level during
installation

5.3.4 Auto-mode
This mode can be chosen by remote controller
and the setting temperature can be changed
between 17~3 ℃.
In auto mode, the machine will choose cooling,
heating or fan-only mode according to ΔT (ΔT
=T1-Ts).

The louver operate same as in relevant mode.
If the machine switches mode between heating
and cooling, the compressor will keep stopping
for 15 minutes and then rechoose mode
according to T1-Ts.
If the setting temperature is modified, the
machine will rechoose running function.
5.3.5 Dehumidifier mode
5.3.5.1 Indoor fan speed is fixed at breeze and
can’t be changed. The louver angle is the same
as in cooling mode.
5.3.5.2 Overlow room temperature protection
In dehumidifier mode, if room temperature is
lower than 1 ℃, the indoor fan will stop and not
resume until room temperature exceeds 12℃.
5.3.5.3 Evaporator anti-freezing protection is
active
5.3.6 Forced o eration function
5.3.6.1 Enter forced operation function:
Press the touch button continually, the AC will run
as below sequence:
When the machine is off, pressing the touch
button will carry the machine to forced auto
mode, after this, if pressing the button once
again, the machine will turn into forced cooling
mode.
In forced cooling mode, pressing touch button will
turn off the machine.
5.3.6.2 In forced operation mode, all general
protections and remote control are available.
5.3.6.3 Operation rules:
Forced cooling mode:

11
The indoor fan runs as breeze. After running for
3 minutes, AC will turn to auto mode with 24℃
setting temperature.
Forced auto mode:
The action of forced auto mode is the same as
normal auto mode with 24℃ setting temperature.
5.3.6.4 When there’s indoor unit running in forced
cooling, it is the master forced cooling unit. Other
indoor units will run at forced cooling mode too
and they will be the slave forced cooling unit. The
slave forced cooling units cannot quit forced
cooling mode until the master forced cooling unit
quit.
5.3.6.5 The slave forced cooling units will not be
controlled by other signals except timer off signal.
5.3.6.6 If AC is running in sleep mode and
receives forced operation signal, it will quit the
sleep mode.
5.3.7 Timer function
5.3.7.1 Timing range is 24 hours.
5.3.7.2 Timer on. The machine will turn on
automatically when reaching the setting time.
5.3.7.3 Timer off. The machine will turn off
automatically when reaching the setting time.
5.3.7.4 Timer on/off. The machine will turn on
automatically when reaching the setting “on” time,
and then turn off automatically when reaching the
setting “off” time.
5.3.7.5 Timer off/on. The machine will turn off
automatically when reaching the setting “off” time,
and then turn on automatically when reaching the
setting “on” time.
5.3.7.6 The timer function will not change the AC
current operation mode. Suppose AC is off now, it
will not start up firstly after setting the “timer off”
function. And when reaching the setting time, the
timer LED will be off and the AC running mode
has not been changed.
5.3.7.7 The setting time is relative time.
5.3.8 Slee function mode
5.3.8.1 Operation time in sleep mode is 7 hours.
After 7 hours the AC quits this mode and turns
off.
5.3.8.2. Operation process in sleep mode is as
follow:
When cooling, the setting temperature rises 1℃
(be lower than 3 ℃) every one hour, 2 hours
later the setting temperature stops rising and
indoor fan is fixed as low speed.
When heating, the setting temperature decreases
1℃(be higher than 17℃) every one hour, 2 hours
later the setting temperature stops rising and
indoor fan is fixed as low speed.(Anti-cold wind
function has the priority)
5.3.8.3 Timer off and remote controller off signals
have the priority compared with sleep function.
5.3.8.4 When user uses timer off function in sleep
mode(or sleep function in timer off mode), if the

12
timing is less than 7 hours, sleep function will be
cancelled when reaching the setting time. If the
timing is more than 7 hours, the machine will not
stop until reaches the setting time in sleep mode.
5.3.9 Auto-Restart function
The indoor unit is equipped with auto-restart
function, which is carried out through an auto-
restart module. In case of a sudden power failure,
the module memorizes the setting conditions
before the power failure. The unit will resume the
previous operation setting (not including Swing
function) automatically after 3 minutes when
power returns.
If the memorization condition is forced cooling
mode, the unit will run in cooling mode for 3
minutes and turn to auto mode as 24℃ setting
temp.
5.3.10 Ionizer
The indoor unit is equipped with Ionizer, which is
controlled by the CLEAN AIR button on the
remote controller. When the unit is turned on,
press the CLEAN AIR button to activate the
function. Press it again to stop the function.
During the time when Ionizer is controlled by
remote controller, Ionizer will be turned off
automatically if indoor fan stops running due to
malfunctions or anti-cold-wind. When indoor fan
restarts after malfunctions being eliminated and
anti-cold-wind being released, Ionizer will be
available again.
