Avoid pressing ON/OFF switch frequently.
For protect unit.The third bit dip switch is ON,when outdoor ambient temp. is lower 10
or higher
than 50
,unit will not run in cooling mode;when outdoor ambient temp. is lower -10 or higher
than 0
,unit will can't run in heat mode.if the third dip switch is OFF,it has not limit.
when pressing temp. setting switch to change the temp.,the air conditioner may stop running.which is
because that the temp. controller is started,not unit fault.
during cooling(heating) mode,even if the room temp. lower(higher) than setting temp.,air conditioner
may be also run in this mode,which is normal.
When the wired controller is power on firstly, the screen will display full screen
for two seconds. and
LED and clock zone will show
8888 - 888 - 88 - 8 flicker for 30 seconds. All the switches all invalid
at the time.
The fan speed is fixed, which can not be switched.
Fixed is shown on the line controller.
Air conditioner setting will be changed after operation some minitues using wired controller.
Under the same condition(running mode
setting temp. fan speed and wind direction
adjustment automaticly),everyday repeat operation for air conditioner's start/change,just need
press ON/OFF button.wired controller will display previous content.

If timing, the screen displays the timing time.
If you want to know the present time, go to the first step.
The time increases a minute each time you press + switch.
Timing setting
1.Press CLOCK switch
CLOCK flickers, and the displayed time is the
present time.
2.Press + and - to regulate the time.
The time decreases a minute each time you press - switch.
Setting of power failure compensation function
When the power is on after blackout, the unit will return to the former state if compensation
function is setting. Otherwise, it stops. When restarting the unit, press
ON/OFF switch on
line controller.
For wired controlled type:When J07 is disconnected, it is power failure compensation state.

Failure checking
The following situations are not troubles
symptom
Reason
Water flowing sound
is heard.
When air conditioner starts, or when the compressor starts or stops
during operation, or when the air conditioner is stopped, it
sometimes sounds
gobo gobo . It is the normal sound of the
refrigerant.
Air which blows out from the indoor unit sometimes smells. This
smell results from residents of tobacco smoke, furniture, and
cosmetics stuck inside of the unit.
During operation,
water fog comes
out of indoor unit.
It is switched into blowing mode
during cooling.
The air conditioner may not be
restarted soon after it stops.
To prevent frost from being accumulated on the indoor unit heat
exchanger. It is sometimes automatically sw
itched into the blowing
mode but it will soon return to the cooling mode.
Even if the operation switch is turned on,
cooling, dehumidifying or heating does not
work for three minutes after the air conditioner
is stopped. It is used to protect the electric
circuit. (During the time air conditioner operates
in fan mode.)
Water or steam generates from the
outdoor unit during heating.
It occurs when frost accumulated on the outdoor unit is removed
(during defrosting operation).
When the air conditioner is used, streams of water fog may be seen.
The water fog is condensed by cooling air.
uni t

Influenced by the air temperature,
the fan stops running. It is normal.
The minimum operating time is set in order to protect the compressor.
In normal situation, the minimum operating time is nearly 10
minutes.

1.Installation preparation
Before installation and maintenance,unit changeover switch should lock in power off state,avoiding touch electricity or running
part cause human hurt or death. For ensuring that installation is correct,followed factors should be considered:
(1)all power supply must be accordant with electric parameter on unit nameplate.
(2)if exterior of unit need instal accessory,
there should reserve excess space.
(3)All duct must make heat insulation safeguard to acoid heat or cool capacity loss.
2.Transportation,Suspension
he air conditioner is generally in complete unit.During transportation and suspension,it needs to handle with care to avoid damage
to the panel,which may affect the performance and precision of the unit.
Suspension:
before unit suspension,make sure the center of gravity to garantee suspension safety,consider of inte
rior parts collocation,unit
weight is not equable,unit can be transported using fork vehicle.when suspension,adopt gasket board to aviod carton damaged.Try
to suspend unit,ensuring if it is stable.
there should isolate unit and buiding when unit suspended.Usual
adopt spring or rubber cushion etc. on site.
Before instal suspend girder,followed items need be checked:
1)Obligate space can supply reasonable air organize and enough space(necessary installation space and intervals please refer to
figure 1 )
2)before installation,ensuring there has proper space to ensure every coil's installation and electric wiring.
3)check supporter's structure,ensuring that there has enough intensity to support unit weight.
4)For farther limit about vibration pass when extreme applition,can adopt connection of proper vibration isolater and with free
duct connector
