OPERATING TIPS

Mode operation: AUTO

COOLING MODEL

•When the room temperature is 2 °C higher than the set temperature, the mode will switch between Cooling and Drying.

•During the Drying mode operation, the FAN setting should be switched to LOW for a gently cooling effect during which the fan may temporarily stop rotating.

HEAT & COOL MODEL (Reverse Cycle)

Auto changeover function

•When AUTO CHANGEOVER is selected, the air conditioner selects the appropriate operation mode (Cooling or Heat- ing) according to your room’s present temperature.

•When AUTO CHANGEOVER is first selected, the fan will operate at low speed for about 1 minute while the unit determines the current conditions of the room and selects the proper operation mode.

If the difference between thermostat setting and actual room temperature is more than +2 °C

→Cooling or dry operation

(Monitor operation may be selected if the outdoor temperature is low.)

If the difference between thermostat setting and actual room temperature is within ±2 °C

→Monitor operation

If the difference between thermostat setting and actual room temperature is more than –2 °C

→Heating operation

(Monitor operation may be selected if the outdoor temperature is high.)

•When the room temperature is near the thermostat set- ting, the air conditioner will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes, the air conditioner will once again select the appropriate operation (Heating or Cooling) to adjust the temperature to the value set in the thermostat. (The monitor operation range is ±2 °C relative to the thermostat setting.)

About Mode Operation

*Heating:• Use to warm your room.

•When Heating mode is selected, the air conditioner will stop for about 3 to 5 minutes, after which it will switch to the selected fan setting. This period of time is provided to allow the indoor unit to warm up before beginning full operation.

•When the room temperature is very low, frost may form on the outside unit, and its performance may be reduced. In order to remove such frost, the unit will automatically enter the defrost cycle from time to time. During Automatic Defrosting operation, the heat operation will be interrupted.

•After the start of heating operation, it takes sometime before the room gets warmer.

Cooling: • Use to cool your room.

Dry: • Use for gently cooling while dehumidifying your room.

•You cannot heat the room during Dry mode.

•During Dry mode, the unit will operate at low speed; in order to adjust room humidity, the indoor unit’s fan may stop from time to time.

•The fan speed cannot be changed manually when Dry mode has been selected.

Fan: • Use to circulate the air throughout your room.

During Heating mode:

Set the thermostat to a temperature set- ting that is higher than the current room temperature. The Heating mode will not operate if the thermostat is set lower than the actual room temperature.

During Cooling/Dry mode:

Set the thermostat to a temperature set- ting that is lower than the current room temperature. The Cooling and Dry modes will not operate if the thermostat is set higher than the actual room temperature (in Cooling mode, the fan alone will ope- rate).

During Fan mode:

You can not use the unit to heat and cool your room.

AUTO Restart

In Event of Power Interruption

•Should the power supply to the air conditioner be inter- rupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.

•Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the power supply, reconnect it, and then use the remote control unit to resume operation.

R410A specifications

Fujitsu R410A is a state-of-the-art refrigerant commonly used in air conditioning systems and heat pumps. Recognized for its superior thermal efficiency and environmental considerations, R410A has become a popular choice among manufacturers and consumers alike.

One of the standout features of Fujitsu R410A is its high energy efficiency. This refrigerant operates on a higher pressure than traditional refrigerants like R22, which allows for better heat exchange and thus improves the overall performance of HVAC units. The efficiency is evident in both cooling and heating capacities, which contributes to reduced energy costs for end users. As energy efficiency becomes increasingly important, R410A meets the demands of modern consumers looking for sustainable solutions without sacrificing comfort.

Fujitsu incorporates advanced technologies in their R410A systems to enhance performance further. The variable speed inverter technology found in many Fujitsu air conditioning systems allows for more precise temperature control and improved efficiency. By adjusting the compressor speed according to the cooling or heating demand, these systems can operate at a lower capacity when required, reducing energy consumption and maintaining indoor comfort more effectively.

Another characteristic of Fujitsu R410A is its low global warming potential (GWP). While traditional refrigerants have raised concerns about their impact on climate change, R410A has a significantly lower GWP, making it a more environmentally friendly option. The use of R410A helps meet international regulations aimed at reducing greenhouse gas emissions, positioning it as a sustainable choice in the HVAC industry.

Additionally, Fujitsu units utilizing R410A are known for their quiet operation. Advances in design and engineering minimize noise levels, contributing to a more pleasant indoor environment. Noise-reduction technologies, combined with efficient airflow management, ensure that users can enjoy comfort without disruptive sounds.

Furthermore, Fujitsu provides robust support and maintenance services for R410A systems, ensuring optimal performance over their lifespan. Their commitment to reliability is reflected in the build quality and design of the units, which are engineered for longevity and dependability.

In summary, Fujitsu R410A is a premium refrigerant characterized by high energy efficiency, advanced inverter technology, low global warming potential, and quiet operation. These features make it a preferred choice for modern air conditioning and heating solutions, affirming Fujitsu's commitment to innovation in the HVAC industry while prioritizing environmental responsibility.
