Carrier Duct 42QSS012D8S-1+38QUS012D8S-1 Air Conditioner 12000 BTU R32 Inverter A++/A+++

Installation Flexibility:

• Slim design: The units have a slim design with reduced height, suitable for installations in applications with limited available height.
• Diode air intake: The unit offers the possibility of air intake from the back and the bottom, for more flexible installation.
• Fresh air intake: A ventilation motor can be installed in the fresh air duct, connected to the ventilation joint and work together with the internal fan to increase the volume of fresh air.
• Automatic external static pressure adjustment: With an automatic airflow adjustment function, the unit can adjust its fan speed to a lower or higher curve to decrease or increase airflow depending on the resistance.
• Increased External Static Pressure: Optimized air coil design can provide higher external static pressure.
• Spare dry contact ports: With the spare ports, a remote switch can be easily connected for remote control. The built-in PCB can generate an alarm signal, which can be connected to an external alarm lamp or vibration meter.

• Twin-Rotary DC Compressors: Units from 24,000 to 60,000 BTU are equipped with twin DC rotary compressors, which contribute to high system efficiency and reliability. The two rotary compression cylinders, offset by 180º and the brushless DC motor with the shaft in perfect balance, ensure reduced vibration and lower noise levels, even when operating at very low speeds. There is a wide range between minimum and maximum capacity, so the system is always optimized to provide maximum comfort with extremely high performance levels.

• Access to all components is ensured by simply removing the grille
• Eurovent Performance Certification: The Eurovent Certification certifies the performance of the air conditioning unit according to European and international standards. Read more here.
• Integrated drain pump*: The drain pump can remove condensation water from the unit, up to a height of 750 mm. The drain piping can be installed easily, even in tight spaces (*optional).
• Reliable and durable unit, thanks to the highly efficient rotary DC compressor with Inverter technology.
• Choice of wired (standard equipment) or wireless controller (optional equipment).

Protection against voltage fluctuations (168-264V)

At Carrier we understand the problems that can be created by such fluctuations in the voltage of the electric current and so we designed our units to work when the electric voltage is lower or higher than 230V. Specifically, the units can operate from 168 to 264V, thus providing protection against voltage fluctuations within these limits.

Self-cleaning function

After the air conditioner is turned off, the indoor unit continues to dehumidify with the fan speed set to Extra Low for a few minutes to remove moisture from the indoor evaporator and prevent mold and unpleasant odors from forming.

Operation Programming

Operation scheduling allows you to set the unit to operate at specific times and desired temperatures.

These models have a wired controller.
