2.4 Directional Control

Adjusting vertical air flow

air flow direction. The louver position moves slightly
each time the button is pressed.
● Press "SWING" to engage continuous louver motion.
Note: Please refer to the REMOTE CONTROLLER MANUAL for details
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)
Attention: Isolating the main power supply synchronises the horizontal
louver.
CAUTION
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 about 10s.

Lever
Features (Model dependent)
■ Auto swing of horizontal air flow
Press "SWING" for two secends to
engage vertical blades swing motion.
Note: Please refer to the REMOTE
CONTROLLER MANUAL for details.
■ Louver Memory
Horizontal louver angle is memorised and
will return to the position last selected by
the user.
This will not happen in TURBO mode,
running by manual control buttons, or after
a power interruption.

2.5 Special Functions

■ Compressor Delay
At start-up, a time delay of 3 ~ 4 minutes
protects the compressor.
■ 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.
■ Cold Draft Prevention
To avoid uncomfortable when the air
conditioner get into heating mode, the indoor
unit will preheat before the fan starts. This
delay should only last a few minutes.
■ Auto Restart
The unit will automatically restart after a
power interruption.
Previous user's settings are all recovered.
■ 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.
Interrupting this process may scramble the control logic.
To reverse this, briefly disconnect the electrical supply.
■ WIFI Control*
With WIFI function, the unit can be
controlled either by remote controller or by
your mobile phone. Connect the WIFI
module and communication module with
display board to activate this function.
■ Air Purification*
Ionizer*
Negative ions are added to the air to
simulate the effects of forests and
waterfalls on humans.
Plasma*
Dust particles in the passing air stream are
charged electrically. This enhances dust
collection, odour reduction and reduces
airborne bacteria mortality.
■ Self Cleaning*
Airborne bacteria always grows provided that
there is moisture on the indoor heat excharger.
Regular drying of the exchanger prevents this
growth. By simply pressing the "self clean"
button, the controller will automatically manage
the process.
■ Turbo
The Turbo function makes the unit work
extra hard to reach your present
temperature in the shortest time possible.
