LOUVER POSITION

Maximum down

In COOLING or DRY mode, condensate may form and drip from unit in 
high humidity condition.

Narrow opening

Restricted air flow reduces performance and may cause condensate.

Closed

Do not operate if it will not open – damage may occur.

LOUVER ACTION

After a quick restart, louver may remain static for ±10s.

CAUTION

Lever

Adjusting horizontal air flow

Step 1

ISOLATE the unit at the MAIN switch 
(or unplug)

Step 2

Pull horizontal louver downwards using both hands.

Step 3

Identify the lever/s as indicated. 
[On uppermost part of air outlet and linked to recessed vertical blades].

Step 4

Move the lever/s left or right to guide the air in the desired direction.

Step 5

ENERGISE the unit at the MAIN switch!
(or plug back in)

NOTE: Isolating the main power supply synchronises the horizontal louver.

 

 WARNING!

Do not attempt this adjustment while 
the machine is in operation. 
Accidental contact with the fan may 
cause serious injury.

2.4 Directional Control

Adjusting vertical air flow

●

CAUTION

2.5 Special Functions

 

Compressor Delay

At start-up, a time delay of 3 to 4 minutes 
protects the compressor.

 

Cold Draft Prevention

To avoid uncomfortable drafts in heating 
mode, the indoor unit is preheated before 
the fan starts. This delay should only last 
a few minutes.

 

Auto Defrost

Ice develops on the outdoor unit in 
heating mode. To defrost this ice, the 
indoor fan stops for a few minutes before 
heating continues.

 

Auto Restart

The unit will automatically restart after a 
power interruption.
Previous user settings are all recovered.

 

Turbo    

Turbo function enables the unit to reach 
the preset temperature at cooling or 
heating operation in the shortest time.

 

Silence

When silence function is activated, the 
compressor will operate at low frequency 
and the indoor unit will bring faint breeze, 
which will reduce the noise to the lowest 
level and make a quiet and comfortable 
feeling for sleep.

 

Self Cleaning

Airborne bacteria use the moisture on the 
indoor heat exchanger to grow. Regular 
drying of the exchanger prevents this 
growth. By simply pressing the “self clean” 
button, the controller will automatically 
manage the process.

Cooling only units

Only the indoor fan is active in low speed 
for 30 minutes and the unit turns off. 

Heating & Cooling units [Heat pumps]

Only the indoor fan is active in low speed 
for 13 minutes. Heating is activated for 
1minute then fan only for 1minute  and 
finally it turns off.
This cleaning action may be done as 
frequently as desired.

 

Auto Leak Detection

When refrigerant leakage is detected,
the unit will display “EC” code or flash
LEDs [model dependent].

 

Mildew Prevention    

This function keeps the indoor fan running 
in low speed for 7 – 10 minutes after 
being turned off by the user in cooling 
mode. Drying the water droplets on the 
indoor heat exchanger prevents mildew 
growth.

 

Louver Memory

Horizontal louver angle is memorised and 
will return
to the position last selected by the user.
This will not happen when turbo or 
manual control
buttons are pressed or after a power 
interruption.

Interrupting this process may scramble the control logic. 
To reverse this, briefly disconnect the electrical supply. 

Note: 

1 This function is activated in COOLING or DRY modes. 
2 Before activation the air conditioner is supposed to be in cooling 
mode for more than 30 minutes.
3 Activation will cancel all TIMER settings.
4 Pressing the SELF CLEAN or ON/OFF button again during the 
cleaning cycle, cancels the operation and turns the unit off.
