Frequently Asked Questions - MS 7911 ADLER

How to install the Adler MS 7911 air conditioner?

Place the unit on a flat, stable surface, at least 50 cm from walls and curtains. Connect the exhaust air hose to the window adapter and install it in a window or sliding door. Ensure that the air intake and outlet are not obstructed. Plug the unit into a grounded outlet (220-240 V).

What to do if the 'FULL' (M) indicator flashes?

This indicates that the water tank is full. Turn off and unplug the unit. Place a container under the lower water outlet, unscrew the drain cap, and let the water drain out. Replace the cap and cover after draining.

How to use sleep mode?

In cooling mode, press the 'F' and 'D' buttons on the control panel simultaneously to activate sleep mode. The 'N' indicator lights up. The unit then operates in quiet and economical mode.

How to set the timer?

Press the 'G' button (timer). The LED screen blinks. Use the up 'D' or down 'C' buttons to set the duration from 1 to 24 hours. The timer can be programmed to turn the unit on or off after the set delay.

The air conditioner is not cooling enough, what to do?

Check that doors and windows are closed and curtains are drawn to limit sunlight. Clean the EVA filter if it is dirty. Ensure that the air intake and outlet are not blocked. If the ambient temperature is too high, the appliance may not reach the set temperature.

How to clean the EVA filter?

Turn off and unplug the unit. Remove the filter by unscrewing the screw on the back cover (image G). Wash the filter with warm water (about 40°C) and mild detergent, rinse and dry in the shade before putting it back.

Can I use an extension cord?

No, it is not recommended to use an extension cord. Plug the appliance directly into a grounded wall outlet to avoid any risk of fire or electric shock.

What do error codes 'E1' and 'E2' mean?

Code 'E1' indicates a pipe temperature sensor fault. Code 'E2' indicates an ambient temperature sensor fault. In both cases, contact an authorized after-sales service for repair.

How to perform continuous drainage in dehumidification mode?

Unscrew the drainage cover and remove the water plug. Connect a drainage hose (not supplied) to the water outlet and place the other end in a bucket or drain. This mode is for dehumidification only.

Why doesn't the compressor start immediately?

The compressor is protected by a 3-minute delay after shutdown to prevent damage. Wait this delay before restarting. If the problem persists, check that the ambient temperature is between 7°C and 35°C.

1. Overflow Protection Function "M":

When water in the water pan exceeds the warning level, the machine will automatically sound an alarm, and the "FULL" indicator light "M" will flash. At this time, drain the water according to drainage instructions. After the water is emptied, the machine will automatically return to the original state.

1. Protection Function of the Compressor

To increase the service life of the compressor, it has a 3-minute delay booting protection function after the compressor is turned off.

DRAINAGE INSTRUCTIONS:

This machine has two drainage methods: manual drainage and continuous drainage.

1. Manual drainage – picture F1.

When the device stops after the water is full, you see on control panel the "M" control lamp is flashing. Turn off the device power and unplug the power plug. Move the machine carefully, so as not to spill the water in the water pan at the bottom of the body. Place the water container below the water outlet behind the housing. Unscrew the down cooler drain hole (8) and unplug the water plug, the water will automatically flow into the water container. Keep the drainage cover and the water plug properly. During drainage, the body can be tilted slightly backwards. If the water container cannot hold all the water, before the water container is full, stuff the water outlet with the water plug as soon as possible to prevent water from flowing to the floor or the carpet. When the water is discharged, stuff the water plug, and tighten the drainage cover.

1. Continuous drainage - option applicable to dehumidifying mode ONLY - shown on picture F2.

Unscrew the drainage cover, and unplug the water plug. Set the drainage pipe (not included in kit) into the water outlet. Connect the drainage pipe to the bucket.

TROUBLESHOOTING

Do not repair the device yourself. Qualified repair will void the warranty.

Problem I.: The air conditioning does not work.

Reason 1 : There is no electricity. So, turn it on after connecting it to a socket with electricity.

Reason 2: The overflow indicator displays "FL". So, discharge the water.

Reason 3: The ambient temperature is too low or too high. So, recommend to use the device in at the temperature of 7-35 °C (44-95 °F).

Reason 4: In cooling mode, the room temperature is lower than the set temperature. So, change the set temperature.

Reason 5: In dry mode, the ambient temperature is too low. So, the device should be placed in a room with an ambient temperature of greater than 17 °C ( 62 °F ).

Problem II.: The cooling effect is not good.

Reason 1: There is direct sunlight. So, pull the curtain.

Reason 2: Doors or windows are open; there are a lot of people; or in cooling mode, there are other sources of heat. So, close doors and windows, and add new air conditioner.
