Once energized, the compressor should in no way be restarted unless after 3-minute time interval at least.Once started, the compressor will not be stopped within 6 minutes with the change of room temperature.
When Tamb. Tpreset+1 , the unit will run under cooling mode, in which case the compressor and outdoor fan will start and the indoor fan will run at preset speed.When T amb. Tpreset -1 , the unit will be stopped, in which the compressor will be stopped, the outdoor fan will be stopped after 15 seconds and the indoor fan will run at preset speed. When Tpreset -1 <Tamb.< Tpreset +1 , the unit will maintain its original operating status.
Under this mode, the reversal valve will be de-energized and the temperature can be set within a range from 16 to 30
If it is detected that the system is under antifreeze protection, the compressor will stop, the outdoor fan will stop after 15s delay, and theindoor fan will run at its original speed. When antifreeze protection is released and the compressor has stopped for 3 minutes, the complete unit will resume its original operating status.
When T amb. Tpreset +2 ,the unit will run under cooling mode, here the compressor,outdoor fan and indoor fan will start to run. When Tpreset +2 Tamb. Tpreset +2 , the unit will run under dehumidify mode, in which case the compressor will be stopped after running 6 minutes, the outdoor fan will be stopped after 15 s delay. After the compressor stopped 4 minutes, the compressor and outdoor fan will be restarted to run. Dehumidifying process is so repeated in cycle. When T amb. Tpreset -2 , the compressor will be stopped and the outdoor fan will be stopped after 15 s delay.

Auto Mode Under this mode, the air conditioner will automatically select its run mode (cool, heat or fan) with the change of ambient temperature.
Under this mode, compressor, outdoor fan and reversal valve will stop running, indoor fan will runat preset fan speed.
Protection Function
High Temp. Protection If it is detected that the evaporator tube temperature is too high, the outdoor fan will be stopped. When the tube temperature resumes to normal, the outdoor fan will be restarted.
If unit is turned off or mode switchovered, the reversal valve will be stopped after 2-minute lag.
When the whole unit is running, press this button the unit will turned off; When the whole unit is turned off, press this buttonthe unit will run at Auto mode, Auto fan speed, Swing mode.
Timer FunctionWhen the unit is turned on to preset unit off by wireless remote control, when the time is over the unit will turn off automatically,when the unit is turned off to preset unit on by wireless remote control, when the time is over the unit will turn on automatically.The interval of turning on and turning off is 0.5 hour, the timer range is 0.5-24hours.
Design and Dual 8 nixie tube display
At the first energizing, all designs and Dual 8 nixie tube will completely turned on 3s; When the unit is turned on, the Power/Run design is green, when the unit is not turned on the Power/Run design is red; When the main unit is in Cool mode or is cooling under the Auto mode, the cooling design will turn on;When the whole unit is in Dry mode, the Dehumidifying design will turn on;When the main unit is in Heat mode or is heating under the Auto mode, the heating design will turn on;When preset Timer on or Timer off, the Timer design will turn on;Dual 8 nixie tube displays setting temperature, but defrosting mode will display H1.If to turn off the light or preset sleep function, that all design will turn off except Power/Run design is on.
In Auto mode or Swing mode, after preset the Sleep function, the temperature will not change.
Auto Fan speed controlAt Cool, Heat, Fan modes, the inner fan will accord to ambient temperature automatically select Hi, Mid, Low fan speed, at Dry mode,the fan speed is low, 3 minutes and 30s must be kept at least for each fan speed switchover.
Swing motor control
Could trun on or turn off by the wireless remote control, only when the indoor fan is running and swing function is set. Once generizedthe stepping motor reset and rotate back to position 0 to close the air outlet. Upon start of the unit, it will firstly rotate to position D3, if the unit is cooling the swing function is not set, the guide louver will stay at D1; if the unit is heating the swing function is not set, theguide louver will stay at D2. The guide louver will swing between L-D3; Upon stop of the unit, it will rotate back to position 0.
Memory function:Memory mode, Swing, Set temp, Set fan speed and Timer (if de-energized before the set time, afterre-energized the time of timer will be recalculated, if de-energized after the set time, after re-energized,the unit will run at the status that after the set time). If the unit is running before de-energization, afterre-energization, there is 3 mins delay for the compressor to start, if the unit is stop before de-energization,after re-energization, there is not 3 mins delay for the compressor to start.

The breaker trips at once when it
is set to "ON".
Measure insulation resistance to ground to see
if there is any leakage.
Trip of breaker or blow of
fuse
The breaker trips in few minutes
when it is set to "ON"
Check power supply circuit.
Check if the plug is properly plugged in and
make the loose contact firm.

The circuit or the part of the air conditioner has
malfunction. They heat and break the insulation
and lead to short circuit or creepage. Measure
the insulation resistance or eliminate the malfunc-
t ion one by one. I f the breaker i tself has
malfunction, then replace the breaker.
The transformer connection is loose or has bad
contact or the transformer has malfunction
First, press the manual switch button AUTO,
if there is no response,check based on the
above methods. If it runs normally after
pressing the button,check again whether the
installation position and the connection wire
of the reception head is correct. If it is
correct,then replace the receiver or the re-
mote controller.

Heat insulation for the connection
pipes of the indoor unit and the out-

Make sure that heat insulation for the thick and thin pipes
is good. Heat insulation must also be provided for the
joint andthe exposed part of the copper pipe .

The installation position of the
outdoor unit is not appropriate.Good ventilation must be provided for the
installation position of the outdoor unit.
The outdoor temperature is too high. Properly install the rainproof plate or the sunproof plate. If the
maximum cool air still can not meet the requirement, it is sug-
gested to replace the air conditioner.
Keep certain air tightness indoors, try not to use
electricalappliance with large quantity of heat
The air tightness is not enough. People
come in and out too frequently. There
are heating devices indoors.

The indoor fan motor is burned or breaks
or has the heat protector malfunction.Replace the fan motor or the defective part.
The built-in heat protector of the motor
breaks frequently because the motor
is abnormal.
Replace the fan motor
Wrong connection Make the correction connection based on the
circuit drawing.
The fan does not
run when it is set
to supply air.
The fan capacitor has open circuit or is
damaged.Replace the fan capacitor of the same type
and same specification.
Replace the fan motorThe outdoor fan motor is damaged.
Wrong connection Make the correct connection based on the
circuit drawing
Replace the fan capacitor
Replace the compressor
The outdoor fan capacitor is damaged.

The protector itself has malfunction.
Use the multimeter to check whether the con-
tact of the compressor is on when it is not
overheated. If it is not on, then replace the pro-
tector
