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 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 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 though 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 wall with wall-

mounted 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 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 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.

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.

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.

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.
