OPERATING INSTRUCTIONS

TO OPERATE YOUR HEAT PUMP FOR COOLING —

1.Set the thermostat system switch to COOL and the thermostat fan switch to AUTO.(See

Figure 1)

2.Set the thermostat temperature to the desired temperature level using the tem- perature selector. Please refer to the sepa- rate detailed thermostat user’s manual for complete instructions regarding thermostat programming. The outdoor unit and indoor blower will both cycle on and off to maintain the indoor temperature at the desired cool- ing level.

NOTE: If the thermostat temperature level is re-adjusted, or the thermostat system switch is repositioned, the outdoor unit may not start immediately.The outdoor unit contains a protective timer circuit which holds the unit off for approximately five minutes following a previous operation, or the interruption of the main electrical

power.

FOR HEATING —

1.Set the thermostat system switch to HEAT and the thermostat fan switch to AUTO.

(See Figure 1)

2.Set the thermostat temperature to the desired temperature level using the temperature selector. Please refer to the separate detailed thermostat user’s manual for complete instructions regarding thermostat programming.The outdoor unit and indoor blower will both cycle on and off to maintain the indoor temperature at the desired heating level.

NOTE: If the thermostat temperature level is re-adjusted, or the thermostat system switch is repositioned, the outdoor unit may not start immediately.The outdoor unit contains a protective timer circuit which holds the unit off for approximately five minutes following a previous operation, or the interruption of the main electrical power.

Emergency Heat:

The thermostat includes a system switch position termed EM. HT. This is a back-up heating mode to be used only if there is a suspected problem with the outdoor unit. With the system switch set to EM. HT. the outdoor unit will be locked off, and supplemental heat (typically electric resistance heating) will be used as a source of heat.Sustained use of electric resistance heat in place of the heat pump will result in an increase in electric utility costs.

Defrost:

During cold weather heating operation, the outdoor unit will develop a coating

R-410A specifications

Nordyne R-410A is a widely recognized refrigerant used in modern air conditioning and heat pump systems, known for its efficiency and environmentally friendly attributes. As a hydrofluorocarbon (HFC) refrigerant, R-410A has become the preferred choice for many manufacturers seeking to meet stringent environmental regulations while providing superior cooling performance.

One of the main features of R-410A is its higher energy efficiency compared to older refrigerants like R-22. This efficiency is primarily attributed to its higher pressure capabilities, which allow for improved heat transfer and reduced energy consumption in residential and commercial systems. As energy costs continue to rise, the use of R-410A in HVAC systems offers a viable solution for reducing utility bills while maintaining optimal comfort levels.

R-410A is also non-ozone-depleting, which sets it apart from many traditional refrigerants. While older refrigerants have been phased out due to their potential harm to the ozone layer, R-410A presents a sustainable alternative that aligns with environmental goals. It features a zero ozone depletion potential (ODP), making it a responsible choice for installations concerned with ecological impact.

In terms of technology, R-410A works effectively in both air conditioning and heat pump systems, providing reliable cooling in hot conditions and heat in colder months. It is compatible with a variety of system designs and can excel in both residential and commercial applications. Moreover, the thermodynamic properties of R-410A ensure consistent and reliable performance, regardless of the external temperature fluctuations.

Another characteristic of R-410A is its ability to operate at lower temperatures, which enhances its versatility. This capability allows for the design of systems that can function efficiently in a wider range of climate conditions. As a result, HVAC technicians and contractors benefit from its reliability and performance, leading to less frequent maintenance and enhanced customer satisfaction.

Lastly, R-410A systems are equipped with advanced components that improve overall functionality. These systems often include variable-speed compressors, which optimize energy use based on cooling demand, and advanced refrigerant management technologies that ensure safe and efficient operation.

In conclusion, Nordyne R-410A stands out as a superior refrigerant due to its energy efficiency, environmental benefits, and adaptability across a range of HVAC applications. As the industry continues to innovate and shift toward sustainable solutions, R-410A remains at the forefront of refrigerant technology, ensuring homeowners and businesses alike enjoy efficient and eco-friendly cooling options.
