4-2. Evacuation procedures：
EVACUATION PROCEDURES
Connect the refrigerant pipes (both the liquid and gas
pipes) between the indoor and the outdoor units.
Remove the service port cap of the stop valve on the side of the
outdoor unit gas pipe.(The stop valve will not work in its initial
state fresh out of the factory (totally closed with cap on).
Connect the gage manifold valve and the vacuum pump to the service portof the stop valve on
the gas pipe side of the outdoor unit.
Run the vacuum pump for more than 15 minutes and at this time confirm that the pressure gage
indicates-0.1 Mpa (-76 cmHg).
Check the vacuum with the gagemanifoldvalve,then close the gage manifold valve,and stop the
vacuum pump.
Leave it as is for one or two minutes .Make sure the pointer of the gage manifold valve remains
in thesame position.

Remove the gage manifold valve quickly from the service port of the stop valve.
After refrigerant pipes are connected and evacuated, fully open all stop valves
on gas and liquid pipe sides.
Operating without fully opening lowers the performance and causes trouble.
Pipe length
5m maximum
No gas charge is
needed.
Pipe length
exceeding 5m
Charge the prescribed
amount of gas.
Tighten the cap to the service port to obtain the initial status.
Retighten the cap.

Control mode
1.Major general technical parameters
1 Conditionings for operation: Ambient temperatures: (-15 -+45 ℃), relative humidity
(45 -85%).
2 Remote receiver distance: 50 m.
3Temperature control accuracy: ±1℃.
4Time error: Less than 1%.
5The power supply for the air conditioner is a.c 220V, 50Hz, with its fluctuation in
the range of (160 –253 V).
2. Remote controller
2.1 The picture of the remote controller is as follows:
Displaying Scheme:
1. Control functions of the remote controller (See operating and installation manual) 2.
Display of error codes:
When the system stops running,press the “CHECK”and “↑↓”buttons, “SERVICE”
and “00”will display,”00”is index ,press “∧”and “∨”button to set the value, the index
value is displayed at the timer area .Each index value shows corresponding
content,as follows:
Index value Content
01 Remote controller in trouble
02 Others trouble code area
05 Set the filter clean time area (See operating and installation manual)

3.1 Emergency switch
3.1.1 Press the emergency switch once to turn on the machine and press it again to
turn off the machine; in the automatic mode, the indoor control temperature is set at
24℃with the indoor fan speed setting is automatic.
3.1.2 When the machine is turned on (in the OFF condition), press and hold the
emergency switch for 10 seconds, the controller starts in the trial operation,regardless
of indoor temperature,the trial operation is the forced cooling with the indoor fan
speed being set at high speeds(the air conditioner don’t according to remote controller
communication now,end the function condition is stop power supply.)
3.2Operator-machine communication
The indoor controller and remote controller has a thermal sensor to detect room
temperatures respectively. The indoor temperature is detected by remote controller in
normal state, the control function will be automatically switched over to the thermal
sensor on the indoor unit when the remote controller sensor has malfunction or the
communication malfunction between the remote controller and indoor controller.
3.3 Timer function
3.3.1 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 .
3.3.2 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 .
3.4 The power interruption restoration function
This model can achieve the power interruption restoration function by the selection
of the EEPROM data. The power interruption restoration is applied only for the basic
functions (turning ON and OFF, setting temperatures, modes, fan speeds) and not for
other special functions such as sleep, timing and power-saving run.
3.5 The forced cooling and fixed frequency function
When the system stops running,press the “RESET”and “CHECK”buttons for 5
seconds,the air conditioner will work at fixed frequency mode.
When the system stops running,press the “RUN/STOP”and “↑↓”buttons for 5
seconds,the air conditioner will work at forced cooling mode.
3.6 Water overflow alarm
The duct type air conditioner has a water overflow switch，the water overflow switch is
off in normal state.When water level is go beyond the limit,the water overflow switch
is on,the outdoor is stop after the water overflow switch is on for 30 seconds,and
remote controller will display error code.
4. Working mode
4.1 Automatic run mode
If there is no man-machine communication function after the unit is started, the indoor
fan operates at the ultra-low flowrate for 20 seconds before selecting a run mode; The
room temperatures are detected during this period for the selection of a run mode.
In the first operation:
