EVACUATION PROCEDURES

Connect the r efriger ant pi pes (both the l iquid 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 port of 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 gage manifold valve, 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 the same position.

Remove the gage man ifold valve qu ickly from th e service po rt 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
7m maximum
No gas charge is
needed.

Pipe length
exceeding 7m
Charge the prescribed
amount of gas.

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

Retighten the cap.

6-3. Control function
6-3-1 Emergency switch

6-3-1-1 Press the emergency switch once to turn o

n 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 and the flaps sweep.

6-3-1-2 When the machine is turned on (in the OFF condition),

press and hold the emergency

18

BSGI 09(12)

66.. CCOONNTTRROOLL MMOODDEEL

L

switch for 5 seconds, the buzzer rings for 3 times and the controller starts in the trial operation.

The trial operation is the forced cooling with the indoor fan speed being set at high speeds,

the flaps sweeping and the air conditioner’s operation is irrelevant with room temperatures.

6-3-1-3 If a remote signal has been received during the emergency run, the ma

chine will

operate upon the command of such a remote signal.

6-3-2 Operator-machine communication

6-3-2-1 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.

6-3-2-2 Neither the turning on nor turning of

f operation will cancel the operator-machine

communication function.

6-3-2-3 In default, the air conditioner is set to st

art the operator-machine communication

function.

6-3-3 Timer function

6-3-3-1 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 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.

6-3-3-2 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 after

19

66.. CCOONNTTRROOLL MMOODDEEL

L

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.

6-3-3-3 Neither the turning on nor turning off operation will cancel the tim

er function (Some

remote controller has a simple one-hour timer off function and excludes this operation).

6-3-4 Sleep

6-3-4-1 In the heating, cooling or dehumidifying mo

de, press the “Sleep” button on the remote

controller to start or cancel the sleep function in turn, and at the same time the sleep icon on

the display screen will be on or off accordingly.

6-3-4-2 According to the different needs, there are four dif

ferent sleep modes to choose.

During the time of sleep mode, the set temperature will change automatically.

6-3-4-3 In default, the setting is to cancel the sleep function. Turning off the unit will also

cancel the sleep function.

6-3-4-4 The sleep function is valid for 8 hours. The air condition

er will turns off and cancel the

sleep function after the sleep function works for 8 hours.

6-3-5 High efficient run function (This function is invalid)

In the heating (except for the single cooling unit), cooling o

r dehumidifying mode, it may be set

for high efficient run with the indoor fan speed changed to the high efficient fan speed and the

compressor operating at the highest frequency as available. If the display screen can display

the frequency, the frequency displayed on the screen is up to the maximum. It will restore to

the previous run state after 15 minutes operation automatically.

6-3-6 Automatic run (SMART) mode

If there is no man-machine communication function af

ter 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:

a. When

When -3℃≤T

When these conditions are not met, it will remain in the previous run mode.

When the temperature setting is changed, re-judgment will be made

for the run mode

according to the descriptions mentioned above; when the compressor is halted for 10 minutes,

the re-judgment will be made for the run mode.

The outdoor fan’s speeds are divided into two levels which can be changed over according to

by the indoor unit control. After the system

24

BSGI 09(12)

starts to operate, the indoor unit supplies the outdoor unit (except for the ventilation mode). If

the EEPROM data is read correctly after turning on the power, the indoor unit’s beeper rings

one time, or if it is not the case the beeper will ring two times and the system cannot be started.

Normally, when the indoor unit receives a control signal from the remote controller and

emergency button, the system will be started and the beeper will ring two times, and in other

cases, the beeper will ring one time.

6-3-12-2 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 flap’s position) and not for

other special functions such as sleep, timing and power-saving run.
