1、How to choose an air conditioner：

a. Choice for reference: 150-170W/㎡ for average rooms;
b. Choice for reference: 160-200W/㎡ for small size offices;
c. Choice for reference: 220-350W/㎡ for restaurants;
d. Choice for reference: 200-300W/㎡ for entertaining venues;
e. Choice for reference: 220-280W/㎡ for the top floor.
Note:1W = 3.412btu.

2、Indoor Unit:

For indoor unit installation, the distance between its top and the ceiling shall
not be less than 10 cm -20 cm, and the distance from the ground should be
between 2m to 2.6m. Also the wallboard must be smooth and straight, with its
supporting force of not less than 60 kg.

The location for installing the indoor unit shall be far away from heat source,
the space between it and the door or window should exceed 0.6m

3、Outdoor Unit:

The air conditioner outdoor unit should not occupy public sidewalks, the
distance between the mounting bracket installed along the road (on condition that
the mounting bracket does not affect the public access, it can be installed
horizontally) and the ground must exceed 2.5m. Also we shall remember that: a.
the air flow must run freely . b. we should protect famous ancient buildings during
installation. c. the installation does not affect the traffic.

The distance between air outlet of outdoor unit and the opposite object should
be more than 1 meter, otherwise the machine would stop running because of
overload by heat yield failure.

If the outdoor unit was opposite the resident's door or window, you should
install the machine as far as possible away from the adjacent doors windows and
plants, and the distance shall not be less than the following values: for the r ated
cooling capacity not more than 4.5KW, the distance should be 3m.; for the rated
cooling capacity more than 4.5KW, the distance should be 4m.

It should remember to avoid installing at places where the natural
environment is harsh, such as heavy fumes and wind, direct sunlight or
high-temperature and heat, together with the place where children easily reach.

4. The Unit:

When installing the air conditioner, the outdoor unit should be below the
indoor unit so as to facilitate circle of refrigerant and refrigeration oil .(1)The
height difference between wall mounted indoor unit and the outdoor unit is
generally not more than 5 meters. (2)The connection pipe can't exceed 5 meters,
and the longest is 15 meters. When the length exceeds 5 meters, 20g fluoride is
required to be added for each exceeding 1m.

4-2. Evacuation procedures：

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

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.

Pipe length
5m and 7m maximum
No gas charge is
needed.

Pipe length
exceeding 5m and 7m
Charge the prescribed
amount of gas.

Retighten the cap.

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 machine 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 off operation will cancel the

operator-machine communication function.

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

66.. CCOONNTTRROOLL MMOODDE

E

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 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

timer 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 mode, 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 different 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 conditioner 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 or
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 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:

a. When T

room

– T

set

＞3℃， it starts in the cooling mode;

b. When -3℃≤T

room

– T

set

≤3℃， it starts in the ventilation run mode;

c. When T

room

– T

set

＜-3℃, it starts in the heating mode.

After the first run in the cooling or heating mode, the mode will be
changed as the following:

a. When T

room

– T

set

＞3℃, it will be changed to the cooling mode;

b. When T

room

– T

set

＜-3℃, it will be changed to the heating mode;

c. 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.

When the compressor is turned off in the heating run, the indoor fan does
not stop at once, but until the indoor evaporator temperature is below
230C, but for 30 seconds at the latest.
6-3-8-5 Outdoor fan
The outdoor fan speeds are divided into three levels which can be
changed over according to outdoor ambient temperatures.
6-3-8-6 4-way valve
State: It is electrified in heating.
Switchover: When initially powered on for heating, the 4-way valve is
activated immediately.
In the change from cooling to heating, it needs an interval of 50 seconds
for the 4-way valve to change over from being interrupted to being
activated.

When being auto, the fan speed is determined in the cooling mode (with

the temperature setting of 240C in default).

The high, medium and low fan speeds are same with that in the cooling

mode.

6-3-12 Special notes

6-3-12-1 The outdoor unit of this model is electrified by the indoor unit

control. After the system 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

66.. CCOONNTTRROOLL MMOODDE

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.
