4.2 Evacuation procedures：

EVACUATION PROCEDURES

Connect the refrigerant pipes (both the liquid an

d

g

as pipes) between the indoor and the outdoor units.

Remove service port cap of the stop valve A and connect gage manifold valve and vacuu

m

p

ump to it.

Run the vacuum pump for more than 15 minutes and at this time confirm that the pressure
gage indicates -0.1Mpa(-76 cmHg).

Stop pump and keep the pressure for one or two minutes. Make sure the pressure is no
change(if the pressure is changed to high, there is some leakage for the pipe connection).

Remove gage manifold valve quickly from the service port of the stop valve A.
full open the stop valves A on gas and liquid pipe sides.

T ot al pi pe len gth is in the range :

N

o gas charge is needed

T ot al pipe length exceeding the limit:
Charge the prescribed amount of gas.

Tighten the cap to the service port to obtain the initial status.

Retighten the cap.

Leak test

Repeat the steps above for other valves(B\C\D), be sure all refrigerant pipes are
connected and evacuated, and all valves are full opend.

3.1Emergency switch

1. When the machine is turned OFF, by press and hold the emergency switch for 5
seconds, with 3 beeps , the indoor unit would turn to emergency run. In such station,
machine would be forced to turn to cooling operation with the indoor fan speed being set at
high speed, the flaps sweeping and the air conditioner’s operation is irrelevant with room
temperatures.

2. If a remote signal has been received during the emergency run, the machine will
operate upon the command of such a remote signal.

3.2 Operator-machine communication

The air conditioner has a thermal sensor to detect room temperatures. Some remote
controller is equipped with a thermal sensor (Such remote controller has the function of
man-machine communication. For details, refer to the section for the remote controller). In
addition, there is a thermal sensor at the indoor air inlet. In the case where the remote
controller is equipped with a thermal sensor, the default setting for room temperatures is
subject to the detection by the remote controller. The remote controller detects the room
temperature once every 20 seconds, and automatically transmits a signal at an interval of 3
minutes or when a change in the room temperature is detected. If the indoor control unit has
not received a remote signal for more than 10 minutes, the control function will be
automatically switched over to the thermal sensor on the indoor unit.

3.3 Timer function

1. Timer on: When set to start in a time by the remote controller, the air conditioner starts in
the timer on condition. When the set time is up, the air conditioner will turn on and operates
in the preset conditions after receiving a signal from the remote controller. If the air
conditioner has not received a signal from the remote controller when the set time is up, it
will automatically start and operate in the preset conditions.

2. Timer off: When set to stop in a set time by the remote controller, the air conditioner will
start in the timer off condition. When the set time is up, the air conditioner will turn off after
receiving a signal from the remote controller. If the air conditioner has not received a signal
from the remote controller when the set time is up, it will turn off automatically.

3. Neither the turning on nor turning off operation will cancel the timer function (Some
remote controller has a simple one-hour timer off function and excludes this operation).。

function by mute key, The air conditioner will run by mute fan speed in mute mode

3.7 prevent cooling wind mode

In the heating-run, to prevent the indoor fan from blowing cold air, the indoor fan will stop

or run slowly until the coil is warmth.

3.8 blow waste heating and waste cooling function

The heating mode, remote shutdown, such as indoor heat exchanger temperature is

higher, the wind blowing out opportunities continue to run the waste heat, the wind guiding

vane is adjusted to the horizontal position.

Cool and dehumidification mode after the compressor close, indoor machine will continue
to set the speed of operation for a period of time.

Fan mode, compressor is shut off, the indoor fan immediately stop

3.9 automatically model

This model does not automatically model function, emergency button cannot set the
automatic mode of operation, can use the emergency button shutdown, remote setting the
automatic mode of indoor machine with remote signal.

3.10 dehumidifying mode：

Remote control setting for dehumidifying mode, mandatory for low speed operation of
indoor machine, according to HIGH POWER bond or strong bond also maintain a low wind
speed, the outdoor machine with cooling mode operation.

3.11 wireless remote controller show fault ：

In the indoor machine operation mode, if the product is faulty, continuous by remote
control" sleep" button 4 times, indoor display screen will display the fault code, no fault will
show "00".

3.12 Mode interfere

For the reason that all indoor units use one outdoor unit, outdoor unit can only run
with same mode(cooling or heating), so, when the mode you set is different from the
mode that outdoor is running with, mode interfere occurs. Following shows the mode
interfere scene.

3．Control function

Cooling Anti-freeze Protection

To prevent freezing caused by too low temperature of indoor evaporator, the air

conditioner will implement real-time detection over the indoor coil temperature. If the indoor

coil temperature is too low, the compressor will be prohibited from increasing the frequency or

decrease the frequency even shut down automatically

Heating Overload Protection

To prevent system overload caused by excessive pressure in heating operation, the

machine will implement real-time detection over the indoor fan-coil temperature:

If the indoor coil temperature grows higher, the compressor will be prohibited from

increasing the frequency; If the temperature continues to rise, the compressor will decrease
the frequency; If the indoor coil temperature is too high, the compressor will stop working

immediately. The compressor then will reboot after the indoor coil temperature reduces.

Cooling Overload Protection

To prevent system overload due to excessive pressure during cooling operation, the

machine will implement real-time detection over the outdoor condenser coil temperature:

If the outdoor coil temperature grows higher, the compressor will be prohibited from

increasing the frequency; If the temperature continues to rise, the compressor will decrease

66.. CCOONNTTRROOLL MMOODDEEL

the frequency; If the outdoor fan-coil temperature is too high, then the compressor will stop

working immediately. The compressor will reboot after the outdoor coil temperature reduces.

Discharge Temperature Protection

To prevent working conditions of compressor from deteriorating due to high discharge
temperature, the machine will implement real-time detection over the discharge
temperature.

If the discharge temperature grows higher, the compressor will be prohibited from

increasing the frequency; if the temperature continues to rise, the compressor will decrease the

frequency automatically; if the discharge temperature is too high, the compressor will stop
working immediately. The compressor will then reboot when the discharge temperature
returns to normal condition.

Oil-return Control

When the compressor continues to operate at low frequency, there will be an oil return.
The compressor increases the frequency, and thus to return the oil in refrigerate system to
the compressor.

Operation Mode

1 Mode Categories

Air conditioning mode is the operation mode set by users through remote controller,
four modes are available: cooling, heating, dehumidification, as well as fan mode.

2 Mode conflict

The operating mode of outdoor unit is decided by the operating mode of the indoor unit
firstly booted. Indoor unit subsequently booted will firstly determine whether it’s own mode is
conflict with the outdoor mode. If so, the indoor unit will automatically shut down after three
beeps; If there is no conflict, the indoor unit will boot normally. The relationship of mode
conflict is as follows:

Outdoor four-way Valve Control

Four-way valve of the outdoor machine shuts down when cooling but starts when
heating. The operation of heating defrosting refers to defrosting operation and, when the
heating remote shutdown, the four-way valve disconnects in 50s when the compressor
stops working.

Start-up Protection:

To prevent compressor from restart frequently in the condition that system pressure has
not been completely balanced, it can’t be restarted within 3 minutes.

Pressure Protection:

Pressure switch is normally kept open. When the pressure grows too high, the pressure
switch will close and soft will enter pressure protection control. soft will automatically
decrease the frequency. If the pressure is still unable to return to normal condition after
decreasing frequency, compressor will stop and report the fault code of pressure protection.
