Corrosion, particularly on the condenser and
evaporator fins, could cause product
malfunction or inefficient operation.
Operational
Do not expose the skin directly to
cool air for long time. (Do not sit in the
draft).
Do not use the product for special
purposes, such as preserving foods, works
of art etc. It is a consumer air conditioner,
not a precision refrigerant system.
There is risk of damage or loss of property.
Do not block the inlet or outlet of air
flow.
Use a soft cloth to clean. Do not use
harsh detergents, solvents, etc.
There is risk of fire, electric shock, or
damage to the plastic parts of the product.
Do not touch the metal parts of the
product when removing the air filter. They
are very sharp.
Do not step on or put anything on the
product. (outdoor units)
Always insert the filter securely.
Clean the filter every two weeks or more
often if necessary.
A dirty filter reduces the efficiency of the air
conditioner and could cause product
malfunction or damage.
Do not insert hands or other objects
through air inlet or outlet while the product
is operated.

Do not drink the water drained from
the product.
Use a firm stool or ladder when
cleaning or maintaining the product.
Be careful and avoid personal injury.
Replace the all batteries in the
remote control with new ones of the same
type. Do not mix old and new batteries or
different types of batteries.
There is risk of fire or explosion.
Do not recharge or disassemble the
batteries. Do not dispose of batteries in a
fire.
They may burn of explode.
If the liquid from the batteries gets
onto your skin or clothes, wash it well with
clean water. Do not use the remote of the

come into operation and cause the unit to operate abnormally.
2. The room relative humidity should be less than 80%. If the air conditioner operates beyond this
figure, the surface of the air conditioner may attract condensation. Please set the vertical air flow louver
to its maximum angle (vertically to the floor), and set HIGH fan mode.
3. The optimum performance will be achieved during this operating temperature zone.

After the compressor starts up and keeps
running, mark the minimum value of T3 from the
10th minutes to 15th minutes as T30.
1)If the compressor cumulate running time is up
to 29 minutes and T3< TCDI1, T3 ＋

6.4.4 Auto-mode
This mode can be chosen with remote
controller and the setting temperature can be
changed between 17°C~30°C
In auto mode, the machine will choose cooling,
heating or fan-only mode according to ΔT (ΔT
=T1-Ts).

Indoor fan will run at auto fan of the relevant
mode.
The louver operates same as in relevant mode.
If the machine switches mode between heating
and cooling, the compressor will keep stopping
for 15 minutes and then choose mode
according to T1-Ts.
If the setting temperature is modified, the
machine will choose running function again.
6.4.5 Drying mode
Indoor fan speed is fixed at breeze and can’t be
changed. The louver angle is the same as in
cooling mode.
All protections are active and the same as that in
cooling mode.
6.4.6 Forced operation function
6.4.6.1 Enter forced operation function:
Press the touch button continually, the AC will
run as below sequence:

Forced auto→Forced cooling→Off
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.
6.4.6.2 In forced operation mode, all general
protections and remote control are available.
6.4.6.3 Operation rules:
Forced cooling mode:
ThecompressorrunsatF2frequencyand indoor
fan runs as breeze.After running for 30 minutes.
the machine will turn to auto mode as 24℃
setting temperature.
Forced auto mode:
The action of forced auto mode is the same as
normal auto mode with 24 ℃setting
temperature.
6.4.6.4 When there’s indoor unit running in
forced cooling,it is the master forced cooling unit.
Otherindoorunitswillrunat forcedcoolingmode
too and theywill be the slave forced cooling units.
The slave forced cooling units cannot quitforced
cooling mode until the master forced cooling unit
quit, and turn to cooling mode at low speed with
24℃setting temperature.
6.4.6.5 The slave forced cooling units will not be
controlled by other signals.
6.4.7 Timer function
6.4.7.1 Timing range is 24 hours.
6.4.7.2 Timer on. The machine will turn on
automatically when reaching the setting time.
6.4.7.3 Timer off. The machine will turn off
automatically when reaching the setting time.
6.4.7.4 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.
6.4.7.5 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.
6.4.7.6 The timerfunction will not change theAC
current operation mode. Suppose AC is off now,
it will not startup firstly aftersetting 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.
6.4.7.7 The setting time is relative time.
6.4.7.8 The AC will quit the timer function when
it has malfunction.
6.4.8 Economy function
6.4.8.1 The sleep function is available in cooling,
heating or auto mode.
6.4.8.2. Operation process in sleep mode is as
follow:
When cooling, the setting temperature rises 1℃
(be lower than 30℃) every one hour, 2 hours
later the setting temperature stops rising and the
indoor fan is fixed at 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 at low speed. (Anti-
cold wind function has the priority).
6.4.8.3 Operation time in sleep mode is 7 hours.
After 7 hours the AC quits this mode and turns
off.
6.4.8.4 Timer setting is available
6.4.9 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 suddenpower 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 30
minutes and turn to auto mode as 24℃setting
temp.
If AC is off before power off and AC is required
to start up now, the compressor will have 1
minute delay when power on. Other conditions,

the compressor will have 3 minutes delay when
restarts.
6.4.10 Louver Position Memory Function
When starting the unit again after shutting down,
its louver will restore to the angle originally set
by the user, but the precondition is that the angle
must be within the allowable range, if it exceeds,
it will memorize the maximum angle of the louver.
During operation, if the power fails or the end
user shuts down the unit in the turbo mode, the
louver will restore to the default angle.
6.4.11 8℃Heating(optional)
In heating operation, the preset temperature of
the air conditioner can be as lower as 8℃, which
keeps the room temperature steady at 8℃and
prevents household things freezing when the
house is unoccupied for a long time in severe
cold weather.
6.4.12 Follow me
1) If the indoor PCB receives the signal which
results from pressingthe FOLLOW ME button on
remote controller, the buzzer will emit a sound
and this indicates the follow me function is
initiated. But when the indoor PCB receives
signal which sent from remote controller every 3
minutes, the buzzer will not respond. When the
unit is running with follow me function, the PCB
will control the unit according to the temperature
from follow me signal, and the temperature
collection function of room temperature sensor
will be shielded, but the error detective function
of room temperature sensor will be still valid.
2) When the follow me function is available,
the PCB will control the unit according to the
room temperature from the remote controller
and the setting temperature.
3) The PCB will take action to the mode
change information from remote controller signal,
but it will not affectedby the setting temperature.
4) When the unit is running with follow me
function, if the PCB doesn’t receive any signal
from remote controller for 7 minutes or pressing
FOLLOW ME button again, the follow me
function will be turned off automatically, and the
temperature will control the unit according to the
room temperature detected from its own room
temperature sensor and setting temperature.
6.4.13 Mode conflict
The indoor units cannot work cooling mode and
heating at same time.
Heating mode has a priority.
