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 safety device of the plug has tripped• Reset the safety plug
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.

ProblemPossible CauseSolution
Unit will not turn on.• Power cord unplugged.• Ensure power cord is firmly plugged into outlet.
• Blown fuse or tripped breaker.• Replace blown fuse; reset tripped breaker.
• Electrical power low (“brown out”).• Low voltage protection prevents operation if supply voltage drops below 90 VAC for 115 volt units; 171 VAC for 230 volt units. Contact local electric utility if voltage is low.
• Electrical power outage.• Contact local electric utility.
• Compressor in 3-minute lock-out.• Wait 3 minutes for compressor start.
Unit repeatedly blows fuse or trips breaker.• Other devices sharing circuit results in circuit overload.• Disconnect other devices or move devices to different circuit.
• Incorrect fuse size or type.• Ensure fuse is correct size. Unit requires time-delay fuses.
• Incorrect circuit breaker size.• Ensure circuit breaker is correct size.
• Extension cord used to provide power.• Do not use an extension cord with this air conditioner. If power cord on air conditioner does not reach outlet, have qualified electrician move out- let or install new outlet closer to unit.
Unit does not adequately cool room or area.• Dirty air filter.• Remove and clean air filter.
• Optional charcoal air filter (if used) clogged.• Replace charcoal filter (if desired). NOTE: Optional charcoal filter can- not be cleaned. Filter must be replaced after three months use.

• Vent Control in EXHAUST position.• Vent Control should be in CLOSED position whenever air conditioner is in cooling mode.
• Airflow to or from unit blocked.• Remove any obstruction to airflow from air discharge vent or return air vent on unit.
• Unit improperly sized for room or area.• Reduce cooling area (close doors or otherwise isolate area).
Unit does not adequately cool room or area.• Desired temperature set too high.• Reduce temperature setting to more comfortable level.
• Excessive heat or moisture in area.• Close blinds or curtains on windows exposed to direct sunlight. Vent steam from open cooking containers, showers, etc., from cooling area. Avoid use of heat- producing appliances during hottest part of day.
• Dirty condenser or evaporator coils.• Clean coils. See Maintenance Procedures.
Unit runs excessively long.• Unit replaces older model.• New high-efficiency compressor runs more frequently, but uses less energy, than older, less efficient models.
Water (condensate) in base pan drips into room.• Unit improperly installed.• Depending on model, unit must be installed with slope of 1Am to W to outside. See Installation Instructions.
Unit noisy.• Unit improperly installed, causing vibration when operating.• Review installation procedures. Ensure all mounting hardware is tight and secure.
• Water noise whenever fan runs.• Normal, especially during periods of high humidity.
