Frequently Asked Questions - DWB-123 DAEWOO

How often should I clean the air filter?

Clean the air filter at least once every two weeks during operation. A dirty filter reduces airflow and cooling capacity.

What should I do if the air conditioner does not cool?

First, check that the power cord is plugged in and the main circuit breaker is on. Wait 3-4 minutes after startup for the compressor to engage. Also clean the air filter and ensure no obstacles block the front grille.

Why is water dripping from the unit?

On humid days, water may drip from the rear drain hole or overflow. This is normal. Ensure the unit is tilted slightly downward to the outside for proper drainage.

Can I use an extension cord with this air conditioner?

It is strongly recommended against using an extension cord due to safety hazards. If you must, use a grounded cord rated 250V, 10A minimum. However, a direct wall outlet is preferred.

How do I set the timer to turn off the unit?

While the unit is on, press the TIMER/CANCEL button on the remote control repeatedly to select off times from 1 to 24 hours. The display will show the set time, and the unit will turn off after that period.

What is the Sleep mode and how do I use it?

Sleep mode has two levels: L1 turns off after 4 hours and gradually increases temperature by 3°C (5.4°F); L2 runs at your set temperature and fan speed. Press the SLEEP button on the remote while in Cooling mode to toggle.

How do I replace the batteries in the remote control?

Slide off the cover on the back of the remote, insert two new AAA batteries ensuring correct polarity (+/-), and reattach the cover. Do not use rechargeable batteries.

The unit is noisy – what could be the problem?

Noise may come from loose parts, weak building structure, or water hitting the fan. Tighten any loose parts, provide additional support, or allow water to drain through the drain hole. Some noise is normal in high humidity.

Can I install this air conditioner through a wall?

Yes, through-the-wall installation is possible. Consult an independent servicing dealer for proper installation. The manual provides window installation steps; wall installation may require additional hardware.

How do I clean the condenser coils?

At the beginning of each cooling season, use a soft brush or vacuum cleaner to gently clean the condenser coils (outdoor side). Avoid using water or harsh chemicals. This ensures peak efficiency.

• HOW TO INSERT BATTERIES

1 Remove the COVER from the back of the remote controller.• Slide the Cover according to the arrow direction	Insert two batteries.• Be sure that the (+) and (−) directions are correct• Be sure that both batteries are new	Re-attach the cover.• Slide it back into position
• Do not use rechargeable batteries such batteries differ from standard dry cells in shape, dimensions, and performance.• Remove the batteries from the remote controller if the air conditioner is not going to be used for an extended length of time.

GENERAL INFORMATION

• AIR FLOW AROUND UNIT

Check in door grill and outdoor louvers for air flow obstructions. Do not block air flow to and from unit. The outdoor coil should be checked and periodically cleaned for debris that may collect and block unit air flow. If air flow is obstructed or deflected back into unit, the compressor may cycle on and off rapidly, causing early compressor failure.

• DRAIN HOLE AND WATER DRIPPING OUTSIDE

Locate drain hole at the rear or on the bottom of unit. Water in base pan is picked up by the fan blade and thrown onto the warm outdoor coil where it evaporates. The air conditioner must be installed level or tilted slightly to the outside for proper water disposal. On exceptionally hot and humid days the air conditioner may permit excess water to pass thru rear drain hole or overflow. This should be considered normal.

- DOOR VENT

The door vent for the room air ventilation is lever type. If the door vent lever moves to the left, then close the vent and moves to the right, then open the vent.

Close ← Vent → Open

CARE AND MAINTENANCE

CAUTION

To avoid death or personal injury due to electrical shock, turn fan control OFF and unplug power cord before cleaning or performing maintenance. After cleaning or performing maintenance, reconnect power.

• AIR FILTER

Clean the air filter, which removes dust inside the room.

It should be washed at least once every week during operation.

1. Remove the Air Filter from the front grille by pulling to right.
2. Clean Air Filter with a vacuum cleaner or lukewarm, soapy water.
3. Shake it when clean to remove moisture completely. Reinstall.

NOTE

A dirty Air Filter reduces air flow and the cooling capacity. Do not operate unit without Air Filter.

• CLEANING THE AIR CONDITIONER

1. At least once a year, remove cabinet and thoroughly clean air conditioner. Have the unit inspected by an authorized service man to ensure unit is functioning properly.
2. Wash air conditioner with lukewarm, soapy water as needed. Rinse and dry thoroughly.
3. If using concentrated liquid detergent, dilute in warm water first.
4. Front grille may be wiped off with a cloth dampened in a mild detergent solution.
5. Cabinet may be washed with mild soap or detergent and lukewarm water, then polished with liquid wax for appliances.
6. Condenser and Evaporator coils should be cleaned at the beginning of each cooling season. Use a soft brush or vacuum cleaner to clean them, making sure that the Condenser and Evap
7. Do not use abrasive cleaners. These items scratch, crack and discolor surfaces.

NOTE

To assure continued peak efficiency, condenser coils (weather side of unit) should be checked periodically and cleaned if clogged with soot or dirt from the atmosphere.

ELECTRICAL REQUIREMENTS

• ELECTRICAL GROUNDING INSTRUCTIONS

This appliance is equipped with a three-prong(grounding) plug for protection against possible shock hazards. If a two-prong wall receptacle is encountered, the customer is required to contact a qualified electrician and have the two-prong wall receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code.

WARNING :

To avoid death, personal injury or properly damage due to electrical shock, this unit must be grounded. Do not under any circumstances cut or remove the round grounding prong from the plug. Do not use a two prong adapter.

- USE OF EXTENSION CORD SET.

Because of potential safety hazards under certain conditions, we strongly recommend against the use of an extension cord set. However, if you still elect to use an extension cord, it is absolutely necessary that it is earthed and the marked rating of the extension cord set should be 250V, 10A (Min.). The socket-outlet shall be installed near the equipment and shall be easily accessible.

WARNING :

To avoid death, personal injury or properly damage due to electrical shock, do not use an extension cord or pinch the power cord. Do not remove the warning tag from the power cord.

- REPLACEMENT OF SUPPLY FLEXIBLE CORD.

If the supply flexible cord is damaged, it must be replaced by the manufacturer or its service agent or similarly qualified person in order to avoid a hazard.

CAUTION :

The appliance shall be installed in accordance with national wiring regulations.

BEFORE CALLING FOR SERVICE

When you find something wrong with your room air conditioner, please carefully check the following items. If you are unable to find the cause of trouble, contact your service dealer.

Difficulty	Possible Cause	Suggested Solution
• Air conditioner does not operate.	• No power to unit.	• Confirm power cord is plugged in.• Verify main power switch (main circuit breaker) or fuse of the unit is good.
• Little or no cooling	• Compressor lockout on initial plug in.• Dirty air filter• Is there anything blocking the front?• Air conditioner undersized for application.	• Wait 3 to 4 minutes and restart the unit.• Clean air filter.• When blocked by curtains, blinds, or furnitures, etc., the air flow is restricted and cooling performance is affected.• Check with dealer to determine proper unit capacity for application.
• Noisy unit	• Loose parts• Weak building construction.• Water hitting fan.	• Tighten any loose parts.• Provide additional support.• Normal in high humidity.• Stop noise by allowing water to drain from base fan through drain hole.
• Ordors from unit	• Mold, mildew or algae formation on wet surfaces.	• Place algaecide tablet in base pan• Remove water in base pan through drain hole.
• Water in base pan.	• Normal for operation in humid areas.	• Water in base pan is picked up by the fan blade and thrown onto the warm outdoor coil where water then evaporates.
