Defrosting:
Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that
indoorambient temperature decreased, its cooling capacity will increase or decrease by
outdoor ambient temperature.
If the unit is running in COOL mode and in low termperature, there will be frost formed on
the heat exchanger, when indoor heat exchanger temperature decreased below 0 , the
indoor unit microcomputer will stop compressor running and protect the unit.
℃
Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase
room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
If outdoor temperature becomes very low, please operate with other heating equipments.
When outdoor temperature is low but high humidity, after a long while running, frost will
form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting
function will act, the heat running will stop for 8-10mins.
During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor.
This is due to the defrosting, it isn't malfunction.
After defrosting finished,the heating will recover automatically.

Troubleshooting
CAUTION
Don't attempt to repair the air conditioner by yourself, it can cause an electric shock or
fire. Please check the following items before asking for repair, it can save your time and
money.
Phenomenon
Troubleshooting
Not operate immediately when the air
conditioner is restarted.
There's unusual smell blowing from the outlet
after operation is started.
The unit has no peculiar smell by itself. If has,
that is due to the smell accumulated in the
ambient.
Solution method: Cleaning the filter.
If problem still has, so need to clean air
conditioner. (Please contact with the authorized
maintenance center.)
Sound of water flow can be heard during
the operation.
The air conditioner is started, when it is
running the compressor started or stopped
running, or the unit is stopped, sometimes
there is swoosh or gurgle, the sound is due
to refrigerant flowing they are not malfunctions.
In COOL mode, sometimes the mist emitted
from the air outlet vent.
When the indoor temperature and humidity
are very high, this phenomenon would
happen. This is caused by the room air is
swiftly cooled down. After running for a while,
indoor temperature and humidity will fall
down, the mist will die away.
Creaking noise can be heard when start or
stop the unit.
This is caused by the deformation of plastic
due to the changes of temperature.

Install the rear panel
1.Always mount the rear panel horizontally. Due to the water tray of indoor unit has been adopted the
both-way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is
taking the outlet of the water tray as the center of a circle, the included angle between the evaporator and
level should be 0 or more, that is good for condensing water drainage.
2.Fix the rear panel on the wall with screws.
(Where is pre-covered with plastic granula)
3.Be sure that the rear panel has been fixed
firmly enough to withstand the weight of an
adult of 60kg, further more, the weight should
be evenly shared by each screw.
Install the piping hole
1.Make the piping hole (Ф55) in the wall at a slight downward slant to the
outdoor side.
2.Insert the piping-hole sleeve into the hole to prevent the connection piping
and wiring from being damaged when passing through the hole.
Install the water drainage pipe
1.For well draining, the drain hose should be placed at a downward slant.
2.Do not wrench or bend the drain hose or flood its end by water.
3.When the long drainage hose passing through indoor,
should wrap the insulation materials.

Align the center of the piping flare with the relevant valve.
Screw in the flare nut by hand and then tighten the
nut with spanner and torque wrench refer to the
following:
NOTE: Firstly connect the connection pipe to indoor unit, then to outdoor unit; pay attention
to the piping bending, do not damage the connection
pipe; the joint nut couldn't tighten too
much, otherwise it may cause leakage.
