Refrigerant R32: GWP 675
THE REFRIGERANT
§To realize the function of the air conditioner unit, a special refrigerant
circulates in the system. The used refrigerant is the fluoride R32, which is
specially cleaned. The refrigerant is flammable and inodorous. Furthermore,
it can leads to explosion under certain conditions. But the flammability of the
refrigerant is very low. It can be ignited only by fire.
§Compared to common refrigerants, R32 is a nonpolluting refrigerant with no
harm to the ozonosphere. The influence upon the greenhouse effect is also
lower. R32 has got very good thermodynamic features which lead to high
energy efficiency. The units therefore need a less filling.

WARNING
§Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacture.
§If repair or maintenance is necessary, contact your nearest
authorized Service Centre.Any repairs carried out by unqualified
personnel may be dangerous.
§The appliance shall be stored in a room without continuously
operating ignition sources. (for example: open flames, an
operating gas appliance or an operating electric heater.) Do not
pierce or burn the air conditioner.
§Appliance shall be installed, operated and stored in a room with
a floor area larger than 5m2.
§Air conditioner refrigerant can not charge more than 1.7kg.
§The storage of the air conditioner should be able to prevent
mechanical damage caused by accident.
§Air conditioner must be installed with stop valve cover.
§Appliance filled with flammable gas R32. For repairs, strictly
follow manufacturer’s instructions only. Be aware that
refrigerants do not contain odor and may be tasteless.
§Read carefully the instruction manual before first use.

This product contains fluorinated greenhouse gases
Refrigerant leakage contributes to climate change. Refrigerant
with lower global warming potential (GWP) would contribute less
to global warming than a refrigerant with higher GWP if leaked to
the atmosphere. This appliance contains a refrigerant fluid with a
GWP equal to [675]. This means that if 1 kg of this refrigerant fluid
would be leaked to the atmosphere the impact on global warming
would be [675] times higher than 1 kg of CO2 over a period of 100
years. Never try to interfere with the refrigerant circuit yourself or
disassemble the product yourself. These tasks should be carried

57 GB
only by licensed authorized technician.
Ensure no following objects are under the indoor unit:
§Microwaves, ovens and other hot objects.
§Computers and other high electrostatic appliances.
§Sockets that plug frequently.
The joints between indoor and outdoor unit shall not be reused,
unless after re-flaring the pipe.
The specifications of the fuse are printed on the circuit board, such
as: 3.15A/250V AC, etc.
If your air conditioner is not fitted with a supply cord and a plug, an
anti-explosion all-pole switch must be installed in the fixed wiring
and the distance between contacts should be no less than 2.5 mm.
If your air conditioner is permanently connected to the fixed wiring,
an anti-explosion residual current device (RCD) having rated
residual operating current not exceeding 30 mA should be installed
in the fixed wiring.
Power supply circuit should have leakage protector and air
switch of which the capacity should be more than 1.5 times of the
maximum current.

USEFUL TIPS
Conditions where the Air Conditioner might not run normally
§Within the temperature range provided in following table, the air conditioner
may stop running and other anomalies may arise.
Cooling Outdoor >43oC (Για T1)
>52oC (Για T3)
Indoor <18oC
Heating Outdoor >24oC
<-7oC
Indoor >27oC
§When temperature is too high, the air conditioner may activate the
automatic protection device, so that the air conditioner could be shut down.
§When temperature is too low, heat exchanger of the air conditioner may
freeze, leading to water dripping or another malfunction.
§In long-term cooling or dehumidification with a relative humidity of above
80% (doors and windows open), there might be water condenses or
dripping near the air outlet.
§T1 and T3 refer to ISO 5151.
NOTES FOR HEATING
§The fan of indoor unit will not start running immediately after the heating is
started to avoid blowing out cold air.
§When it is cold and wet outside, the outdoor unit will develop frost over
the heat exchanger which will decrease the heating capacity. Then the air
conditioner will start defrost function.
§During defrost, the air conditioner will stop heating for about 5-12 minutes.
§Vapor may come out from the outdoor unit during defrost. This is not a
malfunction, but a result of fast defrost.
§Heating will resume after defrost is complete.

59 GB
NOTES FOR TURNING OFF THE AIR CONDITIONER
§When the air conditioner is turned off, the main controller will automatically
decide whether to stop immediately or after running for several seconds
with lower frequency and lower air speed.
EMERGENCY OPERATION
§If the remote controller is broken or lost, use
emergency switch button to operate the air
conditioner.
§If this button is pushed when unit is OFF, the
air conditioner will operate in AUTO mode.
§If this button is pushed when unit is ON, the air conditioner will stop running.
ADJUSTMENT OF AIR FLOW DIRECTION
§Use U/D SWING up-down swing and L/R
SWING left-right swing buttons on the remote
controller to adjust the air flow direction.
§For the models without L/R SWING left-right
swing function, the fins has to be moved
manually.
Note: Move the fins while the air conditioner is not in operation, or your fingers
might be insured, and unit can also be damaged.
Never place your hands into the air inlet or outlet when the air conditioner is
in operation.
PAY ATTENTION
§Open front panel of indoor unit.
§The connector must not touch the
terminal board, and is positioned as
