• Use the remote controller carefully.

If it is dropped, thrown or it gets wet, the remote con-

troller may not operate.

When installing on a wall, etc.

•Install the remote controller installation case in a po- sition where the signal reception sound (beep) can

be heard from the indoor unit when the ON/OFF button is pressed.

How to install/remove the remote controller Installing : Insert the remote controller downward. Removing : Pull it up.

■Reference for replacing batteries

When the indoor unit does not respond to the signal from the remote controller, or the display becomes dim, re- place the batteries with new ones (size AAA).

•Though both alkaline batteries and manganese bat- teries can be used, alkaline batteries are recom- mended because their service life is longer than that of manganese batteries.

•The service life of an alkaline battery is about 1 year. However, a battery which the time limit is approach- ing may be exhausted soon. The recommended us- able time limit is indicated (month/year) on the bot- tom of the battery.

•Replace the 2 batteries with new ones of the same type.

•Do not use rechargeable batteries.

•To prevent liquid leakage, take out all batteries when the remote controller is not going to be used for a long time.

•Dispose of exhausted batteries in the correct man- ner.

remote controller malfunctions, EMERGENCY OPERATION can be done using the EMERGENCY OPERATION switch.

1Press the EMERGENCY OPERATION switch.

When the EMERGENCY OPERATION switch is pressed, the unit will operate in test run for 30 minutes at first and then the operation mode shifts to EMER-

GENCY COOL MODE.

Details of EMERGENCY COOL MODE are as shown below. However, the temperature control does not work for 30 min- utes in test run and the unit is set to continuous operation.

The fan speed is set to High in test run and shifts to Medium after 30 minutes.

Operation Mode	COOL
Set temperature	24°C
Fan speed	Medium
Horizontal vane	Auto

The operation mode is indicated by the Operation Indicator lamp on the indoor unit as following figures.

One key feature of the MCF-18TN/24TN is its inverter technology. By using advanced inverter compressors, these units can adjust their cooling or heating output to match the specific requirements of a space. This results in less energy consumption compared to traditional fixed-speed units, as the compressor runs at variable speeds depending on the desired temperature. Inverter technology also enhances comfort by reducing temperature fluctuations and ensuring more consistent indoor conditions.

Another standout characteristic is the unit's high energy efficiency rating. The MCF-18TN/24TN is designed to operate efficiently even under varying load conditions. The high EER (Energy Efficiency Ratio) and COP (Coefficient of Performance) ratings mean that users can expect reduced electricity bills while still enjoying a comfortable environment. This is particularly beneficial in regions with extreme temperatures, where consistent heating and cooling are essential.

The MCF-18TN/24TN also incorporates advanced filtration systems, ensuring that indoor air quality is not compromised. With a multi-layered filtration system, these units effectively capture and eliminate airborne particles, allergens, and pollutants. This feature is especially important for those with respiratory issues or allergies, as it promotes a cleaner and healthier indoor environment.

Moreover, the user-friendly controls of the MCF-18TN/24TN series enhance the overall experience. The intuitive remote control and display panel allow users to easily adjust settings, set timers, and switch between cooling and heating modes with minimal effort. Smart features, such as programmable schedules and energy-saving modes, add an extra layer of convenience.

In terms of design, the MCF-18TN/24TN units are compact and aesthetically pleasing, making them a suitable addition to any modern space. Their sleek appearance complements a variety of interior styles while occupying minimal wall or floor space.

Overall, the Mitsubishi Electronics MCF-18TN/24TN series stands out for its combination of energy efficiency, advanced technology, and user-friendly operation. With its inverter technology, high energy ratings, superior air filtration, and smart features, these air conditioning units provide an effective and reliable solution for achieving consistent comfort in diverse environments.
