Evaporator Anti−Freezing Protection
The evaporator anti−freezing protection condenser high
temperature protection and outdoor unit frequency limit are active
and the same as that in the COOLING mode.
Outdoor Fan
The outdoor fan operates the same as in the COOLING mode.
FORCED OPERATION Function
When the machine is off, press the touch button to engage the
FORCED AUTO mode. Press the button again within 5 seconds
to engage the FORCED COOLING mode. In the FORCED
AUTO, FORCED COOLING or any other operation mode, press
the touch button to off the machine.
FORCED OPERATION Mode
In the FORCED OPERATION mode, all the general protections
and remote control are available.
Operation Rules
FORCED COOLING Mode:
The compressor runs at the F2 frequency and the indoor fan runs in
the BREEZE mode. After running for 30 minutes. the machine
enters AUTO mode at the 75.2
FORCED AUTO mode:
The FORCED AUTO mode is the same as the normal AUTO
_ _
mode with a 75.2 F(24 C) setting temperature.
AUTO−RESTART Function
The indoor unit is equipped with the AUTO−RESTART function,
which is carried out through an auto−restart module. In the event of
a sudden power failure, the module memorizes the setting
conditions prior to the power failure. The unit resumes the previous
operation setting (not including
automatically three (3) minutes after the power returns.
If the memorization condition is the FORCED COOLING mode,
the unit will run in the COOLING mode for 30 minutes and turn
to the AUTO mode at the 75.2
If the air conditioner is off before the power turns off and the air
conditioner is required to start up, the compressor delays start up
for 1 minute before powering on. In other instances, the
compressor waits three (3) minutes before restarts.

Refrigerant Leakage Detection
With this new technology, the display area displays "EC" when the
outdoor unit detects a refrigerant leak. This function is only active
in cooling mode. It can better prevent the compressor being
damaged by refrigerant leakage or compressor overload.
S
Open Condition: When the compressor is active, the
value of the Coil temperature of evaporator T2 has no
change or very little change.
Louver Position Memory Function
When starting the unit again after shutting down, the louver returns
to the angle originally set by the user, however the precondition is
that the angle must be within the allowable range, if it exceeds, it
will memorize the maximum angle of the louver. During operation,
if the power fails or the end user shuts down the unit in the turbo
mode, the louver returns to the default angle.

46 F (8 C) Heating
When the compressor is running, the indoor fan motor runs
without the ANTI−COLD air function. When the compressor is
off, the indoor fan motor is off.
Silence Operation
Press the SILENCE button on the remote controller to initiate the
SILENCE function. When the SILENCE function is activated,
the compressor running frequency remains lower than F2 and the
indoor unit emits a faint breeze, which reduces the noise to the
lowest level and create a quiet and comfortable room for the user.
Point Check Function
Press the remote controller's LED DISPLAY or LED or MUTE
button three times, and then press the AIR DIRECTION or
SWING button three times in ten seconds, the buzzer rings for two
seconds. The air conditioner enters into the information enquiry
status.
Press the LED DISPLAY or AIR DIRECTION button to check
the next or front item's information.
When the air conditioner enters the information enquiry status, it
displays the code name in 2 seconds.
