USING THE 1-HOUR OFF TIMER

1. 1-Hour OFF Timer

This function causes the unit to operate for one hour and then stop, regardless of whether the unit is on or off when this button is pressed.

The indicator in the display indicates that this function is operating.

Setting procedure:

ADJUSTING THE AIRFLOW DIRECTION

The vertical airflow can be adjusted by moving the flap with the remote controller. Do not move the flap with your hands. Confirm that the remote controller has been turned on. Use the FLAP button to set either the sweep function or one of the six airflow direction settings.

A. Sweep function

The flap starts moving up and down to deliver air over the sweep range.

Regardless of whether the unit is operating or stopped, press the 1 HR. TIMER button.

appears in the display.

Cancellation procedure:

Press the ON/OFF operation button to turn the unit off, wait for the unit to stop operating, and then press the ON/OFF operation button again.

The 1-Hour Timer function is now cancelled and the unit operates normally.

NOTE

B. Setting the airflow manually

Referring to the above illustration, use the FLAP button to set the airflow direction within the range used during the heating, cooling, or dehumidifying operation.

If, while the 1-Hour Timer function is operating, the 1HR. TIMER button is pressed once to cancel the function and then again, the unit continues to operate for one hour from that point in time and then stops.

It is not possible to use the OFF Timer and 1-Hour OFF Timer together. Whichever function is set last takes precedence. If the 1 HR. TIMER button is pressed while the TIMER OFF function operates, the OFF Timer is cancelled and the unit will stop operating one hour later.

2.Operation together with the daily ON/OFF repeat timer

The 1-Hour OFF Timer setting is given priority over the DAILY ON/ OFF REPEAT setting.

NOTE

The flap automatically closes when the unit is off.

During the heating operation, the fan speed will be very low and the flap will be in the horizontal position (position ) until the air being blown out of the unit begins to warm. Once the air warms up, the flap position and fan speed change to the settings specified with the remote controller.

CAUTION

Use the FLAP button on the remote controller to adjust the position of the flap. If you move the flap by hand, the flap position according to the remote controller and the actual flap position may no longer match. If this should happen, shut off the unit, wait for the flap to close, and then turn on the unit again; the flap position will now be normal again.

Do not have the flap pointed down during cooling operation. Condensation may begin to form around the air vent and drip down.

R410A specifications

Panasonic R410A is a refrigerant that has gained significant popularity in the air conditioning and refrigeration industry due to its favorable environmental properties and performance characteristics. Specifically designed to replace the harmful R22 refrigerant, which is being phased out due to its ozone-depleting potential, R410A offers a more eco-friendly alternative without compromising on efficiency or power.

One of the main features of R410A is its high energy efficiency. It operates at a higher pressure than R22, resulting in better heat transfer capabilities. This increased efficiency translates to lower energy consumption, making units using R410A more cost-effective in the long run. Additionally, R410A is known for its ability to provide excellent cooling performance even in high-temperature environments, making it suitable for a variety of applications, from residential air conditioning systems to commercial refrigeration units.

In terms of composition, R410A is a blend of two hydrofluorocarbons (HFCs), namely R32 and R125. This combination not only minimizes ozone depletion potential (ODP) but also reduces global warming potential (GWP) compared to older refrigerants. Panasonic has emphasized the importance of innovative technologies in its products, and R410A aligns perfectly with the company's commitment to developing sustainable solutions.

Panasonic also integrates advanced technologies to optimize the performance of R410A systems. For example, variable speed compressors, known as inverter technology, enhance system efficiency by adjusting the compressor's speed according to the cooling demand. This ensures that energy is only consumed when needed, further reducing operational costs.

Furthermore, R410A has a wide range of applications, including air conditioning systems, heat pumps, and chillers. Its versatility makes it a popular choice among manufacturers and consumers alike. The refrigerant is also compatible with existing R22 equipment, although specific retrofit procedures must be followed to ensure peak performance and reliability.

In conclusion, Panasonic R410A stands out as an innovative refrigerant choice in the HVAC industry, offering a combination of energy efficiency, environmentally friendly properties, and advanced technologies. As regulatory frameworks continue to tighten on greenhouse gas emissions, R410A and similar refrigerants are expected to play a crucial role in shaping a more sustainable future for air conditioning and refrigeration. Its high performance and lower environmental impact solidify its position as a leading refrigerant in contemporary cooling solutions.
