Before you ask for servicing or repairs, check the following points.

Recheck

These are not failures.

Inoperative

The main power switch is turned off.

• The circuit breaker is activated to cut off power supply.

The main power fuse has blown out.

Stoppage of electric current.

Does not cool well or heat well

The air inlet and/or outlet of the outdoor unit is blocked.

Doors or windows are opened.

• The fan speed is set to low.

The air conditioner is set in the DRY mode.

The set temperature is too high. (In cooling operation)

The set temperature is too low. (In heating operation)

Indoor unit or outdoor unit makes a strange noise.

• When the temperature suddenly changes, the indoor or outdoor unit occasionally makes a strange noise because of expansion/ contraction of parts or change of refrigerant flow.

The room air is smelly or a bad odor comes from the air conditioner.

Smells impregnated in the walls‚ carpets, furniture, clothing, or furs, come out.

Outdoor unit is frosted in heating operation.

Water drains from outdoor unit.

The outdoor unit is sometimes frosted in heating operation.

In that case, the unit automatically performs defrosting (for 2 to 10 minutes) for increasing the heating efficiency.

• In defrosting operation, both the indoor and outdoor units stop air flow.

Calm

• Hiss sound is heard when flow of the refrigerant is changed for defrosting.

Resultant water of automatic defrosting in heating operation drains from outdoor unit.

Air flow changes though the FAN button is not set to the AUTO mode.

• When the temperature of blown air drops in heating operation, the air conditioner automatically changes or stops air flow from the indoor unit not to make persons in the room feel chilly.

Air flow from the indoor unit is occasionally changed in the cooling operation.

A white mist of chilled air or water is generated from the outdoor unit.

• The indoor unit in cooling operation or the outdoor unit in defrosting operation occasionally steams.

The inverter allows for smooth operation at varying speeds, reducing energy consumption while maintaining a consistent indoor climate.

Both models offer exceptional efficiency ratings. With a high energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER), these units are designed to operate sustainably while delivering powerful performance. The RAV-SM1100UT-E offers a cooling capacity of 11 kW, while the RAV-SM1400UT-E boasts a more robust 14 kW, making them suitable for a range of spaces from smaller offices to larger commercial properties.

Another significant characteristic is their quiet operation. Toshiba has engineered these units to minimize noise levels, ensuring a tranquil environment. This is particularly beneficial in settings like hotels, restaurants, and workplaces where noise can be disruptive.

The RAV-SM series is also equipped with intelligent control technology. This feature allows users to manage the system from anywhere using a smartphone app, providing convenience and flexibility. Integration with smart home systems further enhances usability, making it easy to program schedules and adjust settings remotely.

Additionally, both models employ a variety of robust filtration systems, ensuring that the circulated air is clean and healthy. With filters that capture dust, allergens, and other particles, these units contribute to improved indoor air quality.

Durability is another hallmark of Toshiba's design philosophy. These air conditioners are built with high-quality materials, ensuring long-lasting performance and reliability even in demanding environments. The RAV-SM models are also designed to work efficiently in low outdoor temperatures, extending their usefulness throughout the year.

In summary, the Toshiba RAV-SM1100UT-E and RAV-SM1400UT-E air conditioners represent a fusion of innovation, efficiency, and user-centric design. With their advanced inverter technology, energy efficiency, quiet operation, intelligent controls, and durable construction, they stand as ideal solutions for those seeking effective climate management in their spaces.
