SAFETY INSTRUCTIONS
Important!
• Carefully read the instructions before operating the unit
• This appliance comprise of an indoor and an outdoor unit. The indoor slim evaporator is
designed exclusively for indoor installations while the external condenser should be
installed outside while still away from flood water or snow line.
• Rating: This unit must be only connected to a 220-240 V / 50 Hz earthed power source.
• Installation must be in accordance with regulations of the country where the unit is used.
• These air conditioners are supplied with refrigeration pipes and electrical cables, and in the
case of QC model with quick connectors, which enables the installer to save time, removes
the need of a vacuum pump, while preventing any leakage of refrigeration gas. However
European Union regulations requires for an F-Gas trained engineer to handle any operation
where non-qualified intervention could case fluorinated gas escape. A commissioning
certificate must be issued with any installation.
• 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
appliances - use it with care.
• Disconnect the power before dismantling, assembling or cleaning.
• Avoid touching any moving parts of 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.
• Do not clean the unit by spraying it or immersing it in water.
• 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 object/edges.
• A damaged supply cord should be replaced by the manufacturer or a qualified electrician in
order to avoid a hazard.
• 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.
• Do not use the appliance for any other purposes than its intended use.
• 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.
• 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 switch located on the remote control.
• Always place the unit on a dry and stable surface. Install the outdoor unit on a wall with
wallmounted brackets or fix on floor slab with special floor mounting slab or brackets away
from flood or snow line.
• The indoor unit should not be installed in laundry or wet rooms

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 start up 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 function when the ambient indoor temperature
is higher than 35℃.
•To protect the unit we recommend not using the heating function when the indoor ambient temperature
is lower than 7℃.
•Note the manufacturer operating temperature ranges at the end of this user manual.
OPERATION
Cooling Mode
The compressor (6) in the exterior 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 led
to the evaporator (1) in the interior unit. The liquid expands into a gas at a low
temperature and low pressure is converted.
This gas absorbs the warmth of the air in the room, the cooled air is blown back
into the room and the heat is moved to the compressor along with the gas.
A fan (3) draws the air over the filter and blows the cooled air back into the
room. A fan (8) draws air over the condenser and blows 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 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 so multiple indoor units are connected to an outdoor compressor. Please make
sure indoor units are set to operate in same mode. You cannot operate 2 indoor units connected to a
single compressor outdoor simultaneously in cooling and respective heating mode but you can set 2
different target room temperatures as long they are set in the same mode. Fan only mode can be operated
in combination with cooling or heating.

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 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 5°C or higher. The performance of
the heat pump will degrade with lowering external temperatures.
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 create an additional heat
load. Normal living spaces require about 100 W per square metre of floor surface. In strong sunlight or if other
sources of heat are present, this may be as much as 350 W/sqm.
Tip: on warm days, let the air conditioner cool the room as much as possible during the night and set the temperature
constant from night to daytime.

If you are installing a multisplit system with easy fit connectors follow the bellow
procedures:
Remove the dust caps from the indoor and outdoor
units and the connecting pipe.
Align the joint of the connecting pipe between the
indoor and outdoor and tighten the connecting nut
manually. Secure it with a wrench as shown applying
maximum torque shown in the table above.
Remove the two valve core caps from the outdoor
unit and turn on the high and low pressure valve
cores with an socket wrench, then tighten the two
valve core caps of the outdoor unit. Finally you can
wrap hot insulating tape around the joints of indoor
and outdoor units
Air purging with vacuum pump
1. Check that pipelines connection have been properly connected, remove the
charging port cap, and connect the manifold gauge and the vacuum pump to
the charging valve by service hoses as shown
2. Open the valve of the low-pressure side of manifold gauge, then run the
vacuum pump. Vacuum the indoor unit and the connecting pipes until the
pressure in them lowers to below 1.5mmHG (The operation time for vacuuming
is about 10 minutes). When the desired vacuum is reached, close the valve of
the low pressure of the manifold and stop the vacuum pump.
3. Disconnect the service hoses and fit the cap to the charging valve.
4. Remove the blank caps, and fully opens the spindles of the 2-way and 3-ways
valves with a service valve wrench.
5. Tighten the blank caps of the 2-way and 3-ways valves, applying the above
torque table

Adding refrigerant
Refrigerant must be added if the piping measures more
than 5 metres (16'5") in length. This operation can only
be performed by a professional F-Gas engineer, for the
additional gas amount, see the below
Gas leakage inspection
After the pipeline connection is done, use a leakage inspection device to carefully check if
there is any leakage at the joints. This is an important step to ensure the quality of
installation. Once a leak is detected, proper action should be taken immediately.
1. For good drainage, the drain hose should be angled downwards.
2. Do not pull on or bend the drain hose or flood its end with water.
3. When the long drainage hose passes through indoor areas, it should be wrapped in insulation.
