Diagnosis of air conditioner is the first thing that should be done before servicing or repairing. This procedure allows to identify breakages and malfunctions in the system: a lack of refrigerant which has to be filled up, errors in the algorithm of the air conditioner, malfunctions of the main units. Timely and competent diagnostics of the malfunctions will allow to eliminate malfunctions in the device.

|Can 1 turn the unit on immediately after unpacking it?||• No. The unit must be placed upright for at least 1 2 hours after every transport. Otherwise the compressor may be damaged and there is no capacity.|
|Unit does not start when pressing power button||• Room temperature is higher than the set temperature (heating mode).||• Reset the temperature|
|• Room temperature is lower than the set temperature (cooling mode)|
|The air conditioner does not come on||• No electricity||• Restore electricity|
|• It is not plugged into the socket||• Plug into socket|
|• The internal safety device has tripped||• Wait 30 minutes, if the problem persists, contact your service center|

|The air conditioner works for a short time only||• There are bends or kinks in the air exhaust hose||• Position the air hose correctly, keeping it as short and free of curves as possible to avoid bottlenecks|
|• Something is preventing the air from being discharged||• Check and remove any obstacles obstructing air discharge|
|Room is not cool enough||• Windows/doors in room are open.||• Close all windows/doors|
|• There are heat sources nearby.||• Remove heat source if possible|
|• Exhaust air duct is not connected or is blocked||• Connect the air duct and make sure it can function properly|
|• Temperature setting is too high.||• Decrease the set temperature|
|• Air filter blocked by dust.||• Clean the air filter|
|The air conditioner does not operate for about three minutes after restarting it||• The internal compressor safety device prevents the appliance from being restarted until three minutes have elapsed since it was last turned off||• Wait. This delay is part of normal operation|
|Noise or vibrations||• The floor level is not in level or the unit is on an incline.||• Place the unit on a flat, level surface.|
|Gurgling sound||• The sound come from the flowing of refrigerant inside the air conditioner||• This is normal|
|When turning the unit on 1 sense a smell. What should 1 do?||• First use or incorrect storage of unit at e.g. dusty areas.||• Odor development can arise on first use and after a longer period of non-use by storing in unsuitable areas (e.g. dusty areas). Run the unit for V2 a day. The smell will disappear after a while. In the case of intensive odor development air the room.|
|Compressor does not activate||• Depending on ambient temperatures and unit type it may take approx. 1 0 minutes after starting the compressor until the cooling/heating capacity is reached.|
|The unit deactivates||• On reaching the set required temperature, the unit switches off automatically. Check manual setting of the required temperature as well as the TIMER setting.|
|The unit does not cool correctly||• You achieve the most effective and economical cooling comfort if you already cool the room to be cooled when the room temperature is not yet heated up. Air conditioners operate more effectively if the temperature is maintained. To drastically cool the air in a fully heated room requires much more time and energy.|
