● Use an ELB (Electric Leakage Breaker). If not used, it will cause an electric shock or a

fire.

● Do not operate the system until all the check points have been cleared.

(A) Check to ensure that the insulution resistance is more than 1 megohm, by measuring

the

resistance between ground and the terminal of the electrical parts. If not, do not operate

the system until the electrical leakage is found and repaired.

(B) Check to ensure that the stop valves of the outdoor unit are fully opened and then start

the system.

● Pay attention to the following items while the system is running.

(A) Do not touch any of the parts by hand at the discharge gas side, since the compressor

chamber and the pipes at the discharge side are heated higher than 90 .℃

(B) DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES). It will cause a

serious Accident.

NOTES:

1) Follow local codes and regulations when selecting field wires.

2) The wire sizes marked in the table are selected at the maxim current of the

unit according to the European Standard ,En60 335-1. Use the wires which are

not lighter than the ordinary tough rubber sheathed flexible cord (code

Press the emergency button can realize the starting or closing Machine, starting up

according to the automatic mode of operation（only for cassette type air-conditioner）

3.2 Operator-machine communication
Air conditioning and remote controller is provided with a temperature sensor. The

remote controller on the temperature sensor to detect the default settings of room
temperature at room temperature. If the indoor control unit for long time have not received
remote control signal, will automatically switch to the air conditioner body temperature
sensor.

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

66.. CCOONNTTRROOLL MMOODDEEL

L

57

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。

3.4 Sleep

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.

2. In the heating mode, the set temperature will decrease automatically after the sleep
function is started.

3. In the cooling mode, the set temperature will rise automatically after the sleep function
is started.

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

3.5 High efficient run function

In Cool, Dehumidification, Fan mode, press the "HIGH POWER " to enter the
refrigeration mode, set the temperature automatically adjust to 18℃; the Fan speed is
powerful speed; frequency of high frequency operation.

In the heating mode, powerful function is invalid for H1 wireless remote controller.

3.6 mute function (only for H1 wireless remote controller)

In the indoor machine operation mode，You may turn on mute function and turn off mute
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

66.. CCOONNTTRROOLL MMOODDEEL

L

58

The heating mode, remote shutdown, such as indoor heat exchanger temperature is
higher, the wind blowing out opportunities continue to run the waste heat.

Cool and dehumidification mode , after the compressor close, indoor machine will

continue to set the speed of operation for a period of time.

3.9 automatically model

This model does not automatically model function, emergency button cannot set the

automatic mode of operation, can use the emergency switch shutdown, remote setting the
automatic mode of indoor machine with remote signal. （emergency button only for cassette

type）

3.10 Dehumidifying method:

Remote control setting dehumidifying mode, indoor machine forced to run at low
speed（high power key or a strong bond also maintain a low wind speed）, the outdoor
machine according to the refrigeration mode operation.

3.11 Fault display

If the product operation failure, outdoor and indoor display control panel lights will quote

2.1Cooling Anti-freeze Protection

To prevent indoor air conditioner evaporator temperature is too low, the indoor coil
sensor for real time detection of evaporator. If the indoor coil temperature is too low, the
compressor will protect.

2.2 Overload Protection

the temperature is too high, the compressor will be automatic protection

2.3 Exhaust temperature protection

To prevent deterioration due to high exhaust temperature of compressor, the
machine will realize the real-time detection of the temperature of exhaust gas. If the
temperature is too high compressor automatic protection

2.4 Oil-return Control

When the compressor runs for a long time low frequencies, control system will start

the return oil program. The system in the oil return to the compressor.

2.5Operation Mode

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.

2.6 Four-way Valve Control

Four-way valve of the outdoor machine shuts down when cooling and defrosting
but starts when heating. During the heating process, the four way valve to stop working for a
period of time after compressor disconnect.

2.7 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.

2.8 Pressure Protection:

When the pressure increases to a preset value, the pressure switch will

automatically protect. Compressor will stop and report the fault code protection.
