Operation tips

The following events may occur during normal operation.
1 Protection of the air conditioner.
Compressor protection
• The compressor can't restart for 3 minutes after it stops.
Anti-cold air
• The unit is designed not to blow cold air on HEAT
mode, when the indoor heat exchanger is in one of the
following three situations and the set temperature has
not been reached.
A) When heating has just started.
B) Defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stops running when defrosting.
Defrosting
• Frost may be generated on the outdoor unit during
the heat cycle when outdoor temperature is low and
humidity is high resulting in lower heating efficiency
of the air conditioner.
• During this condition the air conditioner will stop heating
and operation and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes
according to the outdoor temperature and the amount
of frost buildup on the outdoor unit.
2 A white mist coming out from the indoor unit
• A white mist may generate due to a large temperature
difference between air inlet and air outlet on COOL
mode in an indoor environment that has a high
relative humidity.
• A white mist may generate due to moisture generated
from the defrosting process when the air conditioner
restarts in HEAT mode operation after defrosting.
3 Low noise of the air conditioner
• You may hear a low hissing sound when the compressor
is running or has just stopped running.
This sound is the sound of the refrigerant flowing or
coming to a stop.
• You can also hear a low "squeak" sound when the
compressor is running or has just stopped running.
This is caused by heat expansion and cold contraction
of the plastic parts in the unit when the temperature
is changing.
• A noise may be heard due to louver restoring to its
original position when power is first turned on.
4 Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner
has not been used for a long time or during first use
of the unit.
5 A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells
permeated from building material, from furniture,
or smoke.

6 The air conditioner turns to FAN only mode from
COOL or HEAT mode.
When the indoor temperature reaches the temperature
setting on the air conditioner, the compressor will stop
automatically, and the air conditioner turns to FAN
only mode.
The compressor will start again when the indoor
temperature rises on COOL mode or falls on HEAT
mode to the set point.
7 Dripping water may generate on the surface of the
indoor unit when cooling in a high relatively humidity
(relative humidity higher than 80%). Adjust the horizontal
louvre to the maximum air outlet position and select
HIGH fan speed.
8 Heating mode
The air conditioner draws in heat from the outdoor
unit and releases it via the indoor unit during heating
operation. When the outdoor temperature falls, heat
drawn in by the air conditioner decreases accordingly.
At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and
outdoor temperatures.
If a comfortable temperature can't be achieved by the
air conditioner, we suggest you use a supplementary
heating device.
9 Auto-restart function
Power failure during operation will stop the unit
completely.
For the unit without Auto-restart feature, when the
power restores, the OPERATION indicator on the indoor
unit starts flashing. To restart the operation, push the
ON/OFF button on the remote control. For the unit with
Auto-restart feature, when the power restores, after a
delay of 3 minutes to protect the compressor the unit
restarts automatically with all the previous settings
preserved by the memory function.
10 Lightning or a car wireless telephone operating nearby
may cause the unit to malfunction. Disconnect the unit
with power and then re-connect the unit with power
again. Push the ON/OFF button on the remote control
to restart operation.

Troubleshooting tips

Before you contact customer services, check the following
first:
The air conditioner does not start. Check the following:
1 Is voltage present at the plug socket outlet?
2 Check the plug fuse!
3 Is the timer set?
The air conditioner does not provide satisfactory cooling.
Check the following:
1 Has an appropriate temperature been set?
2 Is the air filter soiled? Clean and fit back in place.
3 Are the inlets and outlets on the outdoor unit blocked?
4 Are the doors and windows closed?
The remote control does not work. Check the following:
1 Important! It only works within a range of 8m from the
indoor unit.
2 Are the batteries still OK? Replace if necessary!
3 Have the batteries been inserted correctly? Check that
the + and - terminals are correct!
Stop the air conditioner immediately if one of the following
faults occur. Disconnect the power and contact your
service center.
1 Fuse blows frequently or circuit breaker trips frequently.
2 Other objects or water penetrate the air conditioner.
3 If one of the malfunction codes appears on the LED
display window: E0, E1, E2, E3, E4, E5, F0, F1, F2, F3, F4,
F5, P0, P1, P2, P3 or P4.
NOTE: When more than one malfunction occur, press any
button on the remote control will display the error
codes in sequence, and the unit will respond by a
beep for each press.
4 Other abnormal situations.
caution
• Do not touch the metal parts of the unit when removing
the filter. Injuries can occur when handling sharp
metal edges.
• Do not use water to clean inside of the air conditioner.
Exposure to water can destroy the insulation, leading to
possible electric shock.
• When cleaning the unit, first make sure that the power
and circuit breaker are turned off.
