9.Maintenance and trouble shooting
9.1.Maintenance manual
1) Functional instruction
1.Run mode:cooling dehumidifying air flowing
2.Fan adjusting:HI MID LO
3.Timing:Timing on 1-24 h
Timing on 1-24 h
4.The set temperature range:15 -30
5.Swing automatic swing or fix at a poing
6.Sleep:8 hours
2)Instruction of the run mode:
1Cooling node:
(1)The inner initialized set temperarure is 24 and the initialized fan is HI.
(2)The fan speed is adjustable, in turn of HI MID LO
(3)Asjusting of the temperature:
Each pressing of the key will increase the set temperarute for 1 till
it reaches30 , Each pressing of the key will decrease the set temperarure for1 ,till it
reaches 15
(4)Adjusing of the air direction:
Under the mode of inner fan running, the air direction can be adjusted by,the
synchro motor to control the starting and closing of the motor
2.Dehumidifying mode:
(1)The fan speed is not adjustable
Incase of the ambient temperarute>15 ,the fan speed is LO.and sompressor
is open;
Incase of 12 ambient temperature 15 ,the fan speed is MID,the
Compressor is open;
(2)The air direction is adjustable.
(3)The set temperarure is not adjustable.
3)Air supply mode:
(1) Water full protection
Under any node, when the water full protectuin is detected to be activated,the
buzzer will beepseveral times consecutively,and the water full alarm lamp
will flash on and off with a 0.5 second frequency.The compressor and outer fan
will stoprunning.It will enter air supply mode.The inner fanwill ren at the
former speed.If the water full protection is released in 3 minutes,the controller
will run under previous set mode and the water full alarm lamp will be off.If it
is not released in 3 minutes,. the inner fan will stop running either and whole
machine is under stand-by mode,.But the water full alarm lamp will keep on
flashing rill it is released.
2.Ppotection against freeaing
When the coildepipe temperature sensor detects that the surface temperatrue of
the avaporator T -2 ,the compressor and the fan will stop running,the inner
fan will run at HI speed and the Fan key will be impotent.When the detected
temperature>-8 amd the stop time of the compressor is longer than 3 minutes,
the compressor and the onter fan will be started and the inner fan runs at set
fan speed.
3. Prtection of the compressor
The compressor must be restarted after 3 minutes from the former stop,except
for the power failure.
5) Sleep prostection
1.the function is only activited under cooling mode, and impotent under other
modes.
2.Afer one hour running under cooling sleep, the set temperature will
rise for 1 ,and rise for another 1 after one another hour,after another6
hours of running the complete machine will be shut down.
3.In case that Sleep and Timing Off are set at the same time, the first impotent
not will be activated.
4.In Sleep mode the Timing On will be impotent.
6)Timing function
1.The timing Off can be set when the machine is rumming;the Timing On can be
set when the machine is shut down.
2.The timing range is 1-24h;
Each pressing of the key will raise the set time for 1h;each pressing of
the key will reduce the set rime for 1h.When it is added to 24h the
key or key will cancel the timing.
