SAFETY INSTRUCTIONS
IMPORTANT!
Carefully read the instructions before operating the unit
This appliance comprises of three indoor units and an outdoor unit. The indoor slim
evaporators are designed exclusively for indoor installations while the external
condenser can be installed outside while still away from flood water or snow line.
Always place the unit on a dry and stable surface. Install the outdoor unit on a wall with
wall-mounting brackets or fix to a floor slab with special floor mounting slab bolts or
brackets away from flood or snow lines.
Rating: This unit must be only connected to a 220-240 V / 50 Hz earthed power source.
Installation must be in accordance with the regulations of the country where the unit is
used.
This appliance is intended for permanent installation into a fixed structure, and should
not be installed on vehicles.
The outdoor part of the air conditioner unit must always be stored and transported
upright, otherwise irreparable damage may be caused to the compressor; if in doubt we
suggest waiting at least 24 hours before starting the unit.
These air conditioners are supplied with pre flared refrigeration pipes and electrical
cables, which enables the installer to reduce the installation time.
European Union regulations requires for an F-Gas trained engineer to handle any
operation where non-qualified intervention could cause fluorinated gas to escape. A
commissioning certificate must be issued with any installation.
This air conditioner contains R32 which is a safe efficient refrigerant which has a lower
environmental burden than traditional refrigerants.
The refrigerant used in this air conditioner is an environmentally friendly hydrocarbon
R32, which has a very low Global Warming Potential compared to traditional
refrigerants.
R32 is classed as slightly flammable and as such naked flames and sources of ignition
should be kept a safe distance from the unit.
If you are in any doubt about the suitability of your electrical supply have it checked
and, if necessary, modified by a qualified electrician.
This air conditioner has been tested and is safe to use. However, as with any electrical
appliance - use it with care.
Disconnect the power before dismantling, assembling or cleaning.
Never connect the unit to an electrical outlet using an extension cord. Both the indoor
unit and outdoor must be hardwired by a qualified electrician.
Never operate this appliance if the cord is damaged. Ensure the power cord is not
stretched or exposed to sharp objects or edges.
A damaged supply cord should be replaced by the manufacturer or a qualified
electrician in order to avoid a hazard.
Avoid touching any moving parts within the appliance.
Never insert fingers, pencils or any other objects through the guard
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities. It is also not intended for use by those with a
lack of experience and knowledge, unless they have been given supervision or
instruction concerning the use of the appliance by a person responsible for their safety.
Do not leave children unsupervised with this appliance.

4
Do not clean the unit by spraying it or immersing it in water.
Any service other than regular cleaning or filter replacement should be performed by an
authorized service representative or a qualified air conditioning engineer. Failure to
comply could result in a voided warranty.
This air conditioner is intended for cooling / heating a room to a suitable level for
human comfort, and should not be used for any other purpose such as cooling food.
Avoid restarting the air conditioning unit unless 3 minutes have passed since being
turned off. This prevents damage to the compressor.
Never use the mains as a switch to start and turn off the air conditioning unit. Use the
provided ON/OFF button located on the remote control.
The indoor unit should not be installed in laundry or wet rooms.
Diagrams and pictures provided within the manual are for guidance only. Due to
continual product development, if there is any variance between the manual and the
product received, the information provided on the product should be followed.
ENERGY SAVING AND UNIT SAFETY PROTECTION TIPS
Do not cover or restrict the airflow from the outlet or inlet grills.
For maximum performance the minimum distance from a wall or objects should be 50cm.
Keep the filters clean. Under normal conditions, filters should only need cleaning once every
four weeks (approximately). Since the filters remove airborne particles, more frequent cleaning
maybe necessary, depending on the air quality.
For the initial startup set the fan speed to maximum and the thermostat to 4-5 degrees lower
than the current temperature. After, set the fan switch to low and set the thermostat to your
desired setting.
To protect the unit we recommend not using the cooling mode when the ambient indoor
temperature is higher than 35℃.
To protect the unit we recommend not using the heating mode when the indoor ambient
temperature is lower than 7℃. Performance will be reduced at lower temperatures.
Note the manufacturer operating temperature ranges at the end of this user manual.

HOW AIR CONDITIONERS WORK
COOLING MODE
The compressor (6) in the external unit compresses the refrigerant into a high-temperature, high-
pressure gas. When this gas flows along the cooling fins of the condenser (7), heat is exuded and
the gas condenses into a liquid, which is then led to the evaporator (1) in the indoor unit. The liquid
expands into a gas at a low temperature and low pressure. This gas absorbs the warmth of the air
in the room, and a fan (3) draws the air through the filter and over the evaporator (1), blowing the
cooled air back into the room. The heat is moved to the compressor along with the gas. A fan (8)
draws air over the condenser and blows the warm air away.
1. Evaporator
2. Filter
3. Evaporator Fan
4. Gas Line
5. Liquid line
6. Compressor
7. Condenser
8. Condenser Fan
HEAT PUMP MODE
The system operates in reverse: the condenser works as an evaporator, the evaporator as
a condenser: warm air is blown into the room. It is ideal as a maintenance heating when
outside temperature is not too low and when the indoor temperature is more than 7°C.
DEHUMIDIFYING
As with cooling, the moisture in the air condenses on the cold evaporator at room
temperature acting as a powerful dehumidifier.
NOTE:
This is a multisplit system and multiple indoor units are connected to a single outdoor compressor.
Please make sure that the indoor units are set to operate in the same mode. Multiple indoor units
connected to the same compressor cannot operate in different modes at the same time although
you are able to set different target room temperatures for each unit. Fan only mode can be
operated while other units are in heating or cooling.

IMPORTANT INFORMATION
HEATING MODE
When the air conditioner is placed in heating mode, the indoor unit will appear to be inactive
while it follows it’s preheat procedure to heat the evaporator coils. Once the coils have heated,
the indoor fan will start to run. This process usually takes 1 –3 minutes, and is designed to
ensure that cold air is not circulated.
AUTO RESTART
The air conditioner will automatically restart when electricity is restored after a power cut. If in
doubt, check the settings.
RANGE OF INTERNAL THERMOSTAT
The internal thermostat can be set at a desired temperature between 16 and 32°C. Note that
whether the desired value is achieved depends on the room size, temperature and insulation of
the room.
RANGE OF HEAT PUMP FUNCTION
The heat function can be used when the external ambient temperature is above -15°C. The
performance of the heat pump will degrade with lowering external temperatures. Please note the
performance will reduce when the outdoor temperature drops below 5°C.
CAPACITY
The required cooling or heating capacity depends greatly on the location and/or use of the room
where the air conditioner is installed. Strong sunlight and the presence of people, lights or
equipment creates an additional heat load. Normal living spaces require about 350 Btu per
square metre of floor surface. In strong sunlight or if other sources of heat are present, this may
be as much as 1200 Btu per sqm.
Tip: On warm days, let the air conditioner cool the room as much as possible during the night and
keep the temperature constant from night to daytime.
EMERGENCY START
In the event of a problem, the air conditioner can be operated using the emergency button under
the panel in the indoor unit. Open the front panel and press the button, the air conditioner will:
-heat if the room temperature is 20 °C or less, cool if the room temperature is 25 °C or more and
for values in between will operate in fan mode.
SELECTING THE OPERATIONAL MODE
This is a multisplit system and multiple indoor units are connected to a single outdoor
compressor. Please make sure that the indoor units are set to operate in the same mode. Multiple
indoor units connected to the same compressor cannot operate in different modes at the same
time although you are able to set different target room temperatures for each unit. Fan only mode
can be operated while other units are in heating or cooling.
