Frequently Asked Questions - MMT12CABWCAAXM8 Mabe

How often should I clean the air filter?

Clean the air filter regularly, especially in dusty environments. Remove the filter by opening the panel and sliding it out. Clean with water or a vacuum, and dry before reinserting.

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

Check if the set temperature is appropriate, if the air filter is dirty, if the air inlets or outlets are obstructed, or if there is a heat source in the room. Also ensure the fan speed is not set too low.

How do I set the timer on the remote?

Press the 'timer' button. Use the +/- buttons to adjust the time from 0.5h to 24h. Press 'timer' again to confirm. You can also set the desired mode, temperature, and fan speed that will activate at the scheduled time.

What is the 'sleep' mode and how does it work?

Sleep mode gradually adjusts the temperature for comfort during sleep. In cooling mode, the set temperature increases by 1°C after 1 hour and another 1°C after another hour. In heating mode, it decreases by 2°C each hour. The unit stops after 7 hours.

How do I use the 'clean' function?

With the unit off, press the 'clean' button. The air conditioner runs for up to 35 minutes to clean the evaporator and dry internal moisture, preventing mold and odors. Press 'clean' again or 'on/off' to cancel.

What does the 'fungus proof' function do?

This function automatically runs the fan for 3 minutes at weak speed after the unit is turned off to dry the evaporator and prevent mold growth. It can be set as a default function via the remote.

Can I install the air conditioner myself?

No, installation must be performed by a qualified professional. Improper installation can cause electric shock, fire, or inefficient operation. Contact an authorized service center.

Why does the indoor unit not start immediately after being turned off?

The air conditioner has a protective delay of 3 to 5 minutes before restarting to prevent compressor damage. This is normal.

What should I do if there is an unusual smell from the outlet?

The unit itself does not produce odor. It may be from the environment. Clean the air filter or run the clean function to remove accumulated odors.

How do I replace the remote control batteries?

Slide open the battery cover on the back of the remote. Insert two new 7# (AAA) batteries with correct polarity (+/-). Replace the cover. Dispose of old batteries properly.

Incorrect installation or operation by not following these instructions may cause harm or damage to people, properties, etc. The seriousness is classified by the following indications:

WARNING:

This symbol indicates the possibility of death or serious injury.

CAUTION:

This symbol indicates the possibility of injury or damage to properties.

WARNING:

THIS APPLIANCE CAN BE USED BY CHILDREN AGED FROM 8 YEARS ABOVE AND PERSONS WITH REDUCED PHYSICAL, SENSORY OR MENTAL CAPABILITIES OR LACK OF EXPERIENCE AND KNOWLEDGE IF THEY HAVE BEEN GIVEN SUPERVISION OR INSTRUCTION CONCERNING USED OF THE APPLIANCE IN A SAFE WAY AND UNDERSTAND THE HAZARDS INVOLVE. CHILDREM SHALL NOT PLAY WITH THE APPLIANCE. CLEANING AND USER MAINTENANCE SHALL NOT BE MADE BY CHILDREN WITHOUT SUPERVISION. (Only for the AC with CE-MARKING)E-MARKING).

Don't share the socket with other electric appliance.

Otherwise, it may cause electric shock even fire.

Don't install air conditioner in a place where there is flammable gas or liquid. The distance between them should above 1m.

It may cause fire.

Don't use liquid or corrosive cleaning agent wipe the air conditioner and sprinkle water or other liquid either.

This product contains fluorinated greenhouse gases.

Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute less to global warming that a refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a refrigerant fluid a GWP equal to 2088. This means that if 1kg of this refrigerant fluid would be leaked to the atmosphere, the impact on global warning would be 2088 times higher than 1kg of CO2 over a period of 100 years. Never try to interfere with the refrigerant circuit yourself or desassemble the product yourself and always ask a professional.

The specification of the fuse are printed on the circuit bord, such as: 3.15A/250V AC, etc. como por ejemplo: 3.15 A/250 V AC, etc.

WARNING:

MEANING OF CROSSED OUT WHEELED DUSTBIN: DO NOT DISPOSE OF ELECTRICAL APPLIANCES AS INSORTED MUNICIPAL WASTE, USE SEPARATE COLLECTION FACILITIES. CONTACT YOU LOCAL GOVERNMENT FOR INFORMA-

Don't open the windows and doors for long time when the air conditioner is running.

Otherwise, the cooling or heating capacity will be weakened.

Don't use the air conditioner for other purposes, such as drying clothes, preserving foods, etc.

Don't apply the cold air to the body for a long time.

It will deteriorate your physical conditions and cause health problems.

Set the suitable temperature. It is recommended that the temperature difference between indoor and outdoor temperature should not be too large.

Appropriate adjustments of the setting temperature.

If your air conditioner is not fitted with a supply cord and a plug, an all-pole switch must be installed in the fixed wiring and the distance between contacts should be no less than 3.0 mm.

THE POWER SUPPLY CIRCUIT SHOULD HAVE LEAKAGE PROTECTOR AND AIR SWITCH OF WHICH THE CAPACITY SHOULD BE MORE THAN 1.5 TIMES OF THE MAXIMUM CURRENT.

REGARDING THE INSTALLATION OF THE AIR CONDITIONERS, PLEASE REFER TO THE BELOW PARAGRAPHS IN THIS MANUAL.

notices for use

the conditions of unit can't normally run

Within the temperature range provided in following table, the air conditioner may stop running and other anomalies may arise.

vacuum Pumping Method (R410A refrigerant evacuation must use the vacuum pumping method)

Before working on the air conditioner, remove the cover of the stop valve(gas and liquid valves)and be sure to retighten it afterward.(to prevent the potential air leakage)

1. To prevent air leakage and spilling tighten all connecting nut of all flare tubes.
2. Connect the stop valve, charge hose, manifold valve, and vacuum pump.
3. Fully open the handle Lo of the manifold valve and apply vacuum for at least 15 minutes and check that the compound vacuum gauge reads -0.1MPa(-76cmHg).
4. After applying vacuum, fully open the stop valve with a hex wrench.
5. Check that both indoor and outdoor connections are free of air leakage.

outdoor condensation drainage(Heat pump type only)

check after installation and test operation

check after installation

• electrical safety check

1. If the supply voltage is as required.
2. If there is any faulty or miss connection in each of the power, signal and grounding wires.
3. If the grounding wire of the air conditioner is securely grounded.

- installation safety check

1. If the installation is secure.
2. If the water drain is smooth.
3. If the wiring and piping are correctly installed.
4. Check that no foreign matter or tools are left inside the unit.

- leak test of the refrigerant

Depending on the installation method, the following methods may be used to check for suspect leak, on areas such as the four connections of the outdoor unit and the cores of the cut-off valves and t-valves:

1. Bubble method: Apply of spray a uniform layer of soap water over the suspected leak spot and observe carefully for bubble.
2. Instrument method: Checking for leak by pointing the probe of the leak detector according to the instruction to the suspect points of leak.

test operation

test operation preparation:

• Verify that all piping and connection cables are well connected.
• Confirm that the values at the gas side the liquid-side are fully open.
