Frequently Asked Questions - DMD-M09-I Maxicool

How often should I clean the air filter?

Clean the air filter every two weeks under normal use. Use a vacuum cleaner or wash with water and dry in a cool place. Never operate the unit without a filter.

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

Check if there is a power cut, if the plug is securely inserted, if the fuse has blown, or if the remote control batteries are exhausted. Also ensure the timer is not set incorrectly.

Why is the unit not cooling/heating effectively?

Common causes: dirty air filter, doors or windows open, blocked air inlets/outlets, incorrect temperature setting. Clean the filter, close windows, and remove obstructions.

What do error codes like E0, P5 mean?

Error codes indicate a malfunction. If an E or P code appears on the display, disconnect power and contact an authorized service center. Do not attempt to repair yourself.

Can I use the air conditioner immediately after stopping?

The compressor has a 3-minute restart delay for protection. Wait at least 3 minutes before turning it on again.

How do I operate the unit without the remote control?

Open the front panel and press the manual control button (forced AUTO or forced COOL). For testing only, press twice within 5 seconds for forced COOL.

Why does white mist come out of the indoor unit?

This is normal in cooling mode when humidity is high, or in heating mode after defrosting. It is caused by temperature differences and moisture.

What is the 'Sleep' mode?

Sleep mode adjusts temperature gradually (+1°C per hour in cooling, -1°C in heating) and turns off after 7 hours for energy saving and comfort.

How do I set the timer?

Use the TIMER ON/OFF button on the remote to set the desired start or stop time. The TIMER indicator will light up.

What maintenance is required for the outdoor unit?

Periodic professional maintenance is recommended. Keep the area around the outdoor unit free of obstructions. Do not attempt to clean or repair it yourself.

How the air conditioner works

Cooling

Heating

AUTO operation

• When you set the air conditioner in AUTO mode, it will automatically select cooling, heating(cooling /heating models only), or fan only operation depending on what temperature you have selected and the room temperature.
• The air conditioner will control room temperature automatically round the temperature point set by you.
• If the AUTO mode is uncomfortable, you can select desired conditions manually.

SLEEP operation

• When you push SLEEP button on remote controller during cooling, heating(cooling only type without), or AUTO operation, the air conditioner will automatically increase (cooling) or decrease (heating) 1°C per hour.
• The set temperature will be steady 2 hours later. And the air conditioner will be timer off in 7 hours.
• The fan speed will be automatically controlled.
• This feature can maintain the most comfortable temperature and save more energy for you.

DRYING operation

• The fan speed will be automatically controlled under dry operation.
• During the dry operation, if the room temperature is lower than 10^ C, the compressor stops operation and restarts until the room temperature is above 12^ C.

Operation mode selection

While simultaneously operating two indoor units or more, make sure the operation modes will not conflict with each other. The heat mode claims precedence over all other modes. If the unit initially started operates under heat mode, the other units can operate under heat mode only. For example: If the unit initially started operates under cool(or fan) mode, the other units can operate under any mode except heat. If one of the unit selects heat mode, the other operating units will stop operation and display "P5" (For the units with display window only) or the Auto and Operation indication light flash rapidly, the Defrost indication light turn off, the Timer indication light remain on(For the units without display window), or the Defrost and Alarm indication light(if applicable) illuminate, the Operation indication light flashes rapidly and the Timer indication light turns off ( For the Floor and standing type).

Optimal operation

To achieve optimal performance, please note the following:

• Adjust the air flow direction correctly so that it is not directed on people.
• Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature levels.
• Close doors and windows on COOL or HEAT modes, or performance may be reduced.
• Use TIMER ON button on the remote controller to select a time you want to start your air conditioner.
• Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running.
• Clean the air filter periodically, otherwise cooling or heating per formance may be reduced.
• Do not operate unit with horizontal louvre in closed position.

Suggestion: For the unit adopts an Electric Heater, when the outside ambient temperature is below 0^ C, we strongly recommend you to keep the machine plugged in order to guarantee it running smoothly.

Maintenance

If you plan to idle the unit for a long time, perform the following:

1. Clean the indoor unit and air filter.
2. Select FAN only mode, let the indoor fan run for a while to dry the inside of the unit.
3. Disconnect the power supply and remove battery from the remote control.
4. Check components of the outdoor unit periodically. Contact a local dealer or a customer service centre if the unit requires servicing.

Note: Before you clean the air conditioner, be sure to switch the unit off and disconnect the power supply plug.

When the air conditioner is to be used again:

• Use a dry cloth to wipe off the dust accumulated on rear air intake grille, in order to avoid the dust blowing out from the indoor unit.
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.

Operation Tips

The following events may occur during normal operation.

1. Protection of the air conditioner.

Compressor protection

• The compressor can't restart for 3 minutes after it stops.
  Anti-cold air (Cooling and heating models only)
• The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached.

A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.

- The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).

Defrosting (Cooling and heating models only)

- Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high resulting in lower heating efficiency of the air conditioner.

- During this condition air conditioner will stop heating operation and start defrosting automatically.

- The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost buildup on the outdoor unit.

1. A white mist coming out from the indoor unit

2. A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode in an indoor environment that has a high relative humidity.

3. A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting.

4. Low noise of the air conditioner

5. You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing or coming to a stop.

6. You can also hear a low "squeak" sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
7. A noise may be heard due to louver restoring to its original position when power is first turned on.

4. Dust is blown out from the indoor unit.

This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit.

5. A peculiar smell comes out from the indoor unit.

This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke.

6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models only) mode.

When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to the set point.

1. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.

8. Heating mode (For cooling and heating models only)

The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner, we suggest you use a supplementary heating device.

9. Auto-restart function

Power failure during operation will stop the unit completely.

For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto-restart feature, when the power restores, the unit restarts automatically with all the previous settings preserved by the memory function.

1. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.

Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote controller to restart operation.

Stop the air conditioner immediately if one of the following faults occur. Disconnect the power and contact the nearest customer service center.
Trouble	If the E( 0,1......) or P( 0, 1 ......) code appears on the LED(LCD)window, disconnect the power and contact the service people.
	Fuse blows frequently or circuit breaker trips frequently.
	Other objects or water penetrate the air conditioner.
