To start unit

1POWER - Press the Power button once. The unit will automatically start in the mode and fan speed it was last left on.

To set mode of operation

2COOL - Press the Cool button to automatically switch the operating mode to COOL.

3FAN ONLY - Press the Fan Only button if you want to run the fan only.

4MoneySaver® - Press the MoneySaver® button to activate the MoneySaver® feature. This feature cycles the fan with the compres- sor so that the fan does not run all the time.

To set the timer

NOTE: You can set the START and STOP times a minimum of one hour apart, and a maximum of 23 hours apart.

9TIMER START - Press Start to view the current start time for cooling. Continue pressing the Start button until you arrive at the start time you desire. The start time for cooling will then be set.

10TIMER STOP - Press the Stop button. Continue pressing the Stop button until you arrive at the stop time you desire. The stop time for cooling will then be set.

11TIMER ON / OFF - Press the On/Off button to activate (light on) or deactivate (light off) the timer. Once the on and off times have been selected, they will remain in memory and cycle daily until changed.

NOTE: If the unit is unplugged or the power is interrupted, the Set Hr. function must be reset or the On/Off function will not work.

To adjust temperature setting

5WARMER - Press the Warmer button to raise the temperature setting.

6COOLER - Press theCooler button to lower the temperature setting.

To adjust fan speed

7FAN SPEED - Press the Fan Speed button to see the current set- ting. Press again to change the fan speed. F1 is the lowest setting (SLEEP / LOW), F2 is MEDIUM, F3 is HIGH, and SF is the SMART FAN setting.

To set the hour clock

8SET HOUR CLOCK - Press Set Hr. once to see the current clock setting. Continue pressing the button until you arrive at the current time (Hour only). Minutes are not shown on the display. Make sure that the A.M. / P.M. setting is correct.

R-410A specifications

Friedrich R-410A is an advanced refrigerant widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems, known for its high efficiency and environmental friendliness. As a hydrofluorocarbon (HFC) blend, R-410A has become the preferred alternative to R-22, which is being phased out due to its ozone-depleting potential. One of the main features of R-410A is its high latent heat of vaporization, which allows for efficient heat transfer and improved cooling performance in air conditioning units.

Technologically, R-410A operates at higher pressures than older refrigerants, meaning systems designed for R-410A need to be built with more robust components to safely handle these pressures. This results in a more compact system design that offers enhanced performance and reliability. The dual-component nature of R-410A—composed of difluoromethane (R-32) and pentafluoroethane (R-125)—provides an optimal balance of thermodynamic properties, leading to superior energy efficiency, especially in variable speed applications.

In terms of characteristics, R-410A has a higher cooling capacity, which enables HVAC systems to effectively cool larger spaces or run more efficiently when cooling smaller areas. The refrigerant is non-toxic and non-flammable, which enhances safety during its use. In addition, R-410A has a lower global warming potential relative to other refrigerants, making it a more environmentally responsible choice for modern cooling systems.

Moreover, R-410A systems typically require less refrigerant charge due to their efficiency, contributing to reduced greenhouse gas emissions. The adoption of R-410A aligns with regulatory trends aimed at minimizing the environmental impact of refrigerants in cooling applications.

Overall, the Friedrich R-410A refrigerant embodies a combination of technology and environmental stewardship, making it a cornerstone of contemporary HVAC design. Its ability to provide effective and energy-efficient cooling solutions while being compliant with modern environmental regulations positions R-410A as the refrigerant of choice for engineers and installers focused on sustainability and performance in air conditioning systems.
