Operation hints  
Remote monitoring  
The control board of the indoor unit reserves the communication port for remote control. If  
you install the peripheral equipment according to the manual of the matching remote control  
detector, it can realize the computer management or remote monitoring of the conditioner.  
Please refer to the manual of the " Conditioner remote control detector" for the details  
Power failure resume(please set and apply as necessary)  
With setting of power failure resume, if sudden power failure occurs, the unit will resume  
original operation when power is supplied again.  
Setting method  
With ON of remote controller (except TIMER and FAN),repeatedly press SLEEP button 10  
times in 5 seconds, after 4 Beep from the buzzer, the unit comes into power failure resume  
mode.  
To cancel:  
press SLEEP button continuously 10 times in 5 seconds, the buzzer sounds Beep twice and  
power failure resume function is canceled.  
Note:  
When sudden power failure happens during unit operation in power failure resume mode,if  
the air conditioner is not desired for use in a long period, please shut off the power supply  
in case that the unit automatially resume operation when power is re-supplied, or press  
ON/OFF to turn off the unit when power resumes.

Maintenance  
Cleaning of the unit  
Do not clean with hot  
water or solvent  
Turn off the power switch  
Do not touch with wet hand  
Take off the air inlet grill  
First switch off the power supply, take off the  
screw cap, loosen the screw with cross screwdriver.  
Clean the filter  
Use water or vacuum cleaner to remove  
dust. If it is too dirt, clean with detergent or  
neutral soap water.  
Rinsing with fresh water, dry the filter and  
re-assemble.  
Caution:  
Do not wash filter in hot water above 40oC,  
which will damage the filter.  
Do carefully wipe the filter.  
Clean the indoor(outdoor) unit  
Clean with warm cloth or neutral detergent,  
then wipe away moisture with dry cloth. Do  
not use too hot water(above 40oC), which will  
cause discoloration or deformation. Do not  
use pesticide or other chemical detergents.

Maintenance  
Maintenance at the end of application season  
On a fine day, unit shall be started and operate in  
FAN mode for about half a day unit the inside of  
the unit becomes thoroughly dry.  
Turn off the unit operation switch and power on/off.  
Otherwise, there will be some electricity consumption  
even the unit is in stop status.  
Clean the filter and indoor, outdoor unit, cover  
the units well.  
Maintenance before beginning of application season  
Check there are no obstacles in the air inlet and  
outlet to avoid impairing of working efficiency.  
Please do attach the air filter to ensure the  
electrostatic filters not soiled. Otherwise,dirt  
will come into and damage the unit or bring  
failures.

Trouble shooting  
Before asking for service, check the following first.  
Phenomenon  
Cause or check points  
The system does not restart  
immediately.  
When unit is stopped, it won't restart  
immediately until 3 minutes have elapsed  
to protect the system.  
When the electric plug is pulled out and  
reinserted, the protection circuit will work  
for 3 minutes to protect the air conditioner.  
During unit operation or at stop, a swishing  
or gurgling noise may be heard. At first 2-3  
minutes after unit start, this noise is more  
noticeable. (This noise is generated by  
refrigerant flowing in the system.)  
During unit operation, a cracking noise may  
be heard. This noise is generated by the  
casing expanding or shrinking because of  
temperature changes.  
Noise is heard:  
Normal  
Performance  
inspection  
Should there be a big noise from air flow in  
unit operation, air filter may be too dirty.  
This is because the system circulates smells  
from the interior air such as the smell of  
furniture, cigarettes.  
Smells are generated.  
Mist or steam are blown out.  
During COOL or DRY operation, indoor unit  
may blow out mist. This is due to the sudden  
cooling of indoor air.  
Is power plug inserted?  
Is there a power failure?  
Is fuse blown out?  
Multiple  
check  
Does not work at all.  
Poor cooling  
Is the air filter dirty? Normally it should be  
cleaned every 15 days.  
Are there any obstacles before inlet and outlet?  
Is temperature set correctly?  
Are there some doors or windows left open?  
Is there any direct sunlight through the  
window during the cooling operation?(Use  
curtain)  
Are there too much heat sources or too many  
people in the room during cooling operation?

Installation  
According to the dimension of the Figure 2 shown  
nail two cement steel nails on the wall keep 2-3mm

There must be no gap between the indoor unit and  
wall.  
Remove the front panel,then use two fastening  
screws to fix the unit on the floor. As Figure 3 shown.  
Once refrigerant piping and drain piping connections  
are complete,fill the gap of the through hole with putty.  
Attach the front panel and front grille in their orginal  
positions once all connections are complete.

Connecting method  
Apply refrigerant oil at half union and flare nut.  
To bent a pipe, give the roundness as large as possible not to crash the pipe.  
When connecting pipe, hold the pipe center to center then screw nut on by hand, refer to Fig.  
Be careful not to let foreign matters, such as sands enter the pipe.  
Forced fastening without careful  
centering may damage the  
threads and cause a leakage of gas.
