SAFETY INSTRUCTIONS

Important!

 Carefully read the instructions before operating the unit
 This appliance comprises of an indoor and an outdoor unit. The indoor slim evaporator

is designed exclusively for indoor installations while the external condenser can 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 the regulations of the country where the unit is

used.

 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.

 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.
 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.

 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 objects or 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 purpose other 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 button located on the remote control.

 Always place the unit on a dry and stable surface. Install the outdoor unit on a wall with

wall-mounted brackets or fix to a floor slab with special floor mounting slab bolts or
brackets away from flood or snow lines.

 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 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.

OPERATION
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.

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.

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 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.

EMERGENCY START

In the event of a problem, the air conditioner can be operated using the emergency button under
the panel in the interior 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: dehumidify in a model without a heat pump and in a model with a heat
pump in fan mode.
