SECTION I: GENERAL

The outdoor units are designed to be connected to a matching indoor coil with sweat connect lines. Sweat connect units are factory charged with refrigerant for a matching indoor coil plus 15 feet of field-supplied lines.

The refrigerant charge may need to be changed for some indoor-out- door unit combinations, elevation differences or total line lengths. Refer to Application Data covering “General Piping Recommendations and Refrigerant Line Length” (Part Number 247077).

SECTION II: SAFETY

This is a safety alert symbol. When you see this symbol on labels or in manuals, be alert to the potential for personal

injury.

Understand and pay particular attention to the signal words DANGER,

WARNING, or CAUTION.

DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.

WARNING indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury.

CAUTION indicates a potentially hazardous situation, which, if not

avoided may result in minor or moderate injury. It is also used to

alert against unsafe practices and hazards involving only property dam- age.

This product must be installed in strict compliance with the enclosed installation instructions and any applicable local, state, and national codes including, but not limited to building, electrical, and mechanical codes.

R-410A systems operate at higher pressures than R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. Service equipment Must Be Rated for R-410A.

Improper installation may create a condition where the operation of the product could cause personal injury or property damage. Improper installation, adjustment, alteration, service or mainte- nance can cause injury or property damage. Refer to this manual for assistance or for additional information, consult a qualified con- tractor, installer or service agency.

INSPECTION

As soon as a unit is received, it should be inspected for possible dam- age during transit. If damage is evident, the extent of the damage should be noted on the carrier’s delivery receipt. A separate request for inspection by the carrier’s agent should be made in writing. See Local Distributor for more information.

Requirements For Installing/Servicing R-410A Equipment

Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle the POE type oils, and the higher pressures of R-410A.

Manifold sets should be high side and low side with low side retard.

All hoses must have a 700 psig service pressure rating.

Leak detectors should be designed to detect HFC refrigerant.

Recovery equipment (including refrigerant recovery containers) must be specifically designed to handle R-410A.

Do not use an R-22 TXV.

A liquid-line filter drier is required on every unit.

R-410A specifications

Johnson Controls R-410A is a widely recognized refrigerant in the HVAC industry, primarily used in air conditioning and heat pump applications. Known for its environmental benefits and efficiency, R-410A has risen to prominence as a reliable replacement for older refrigerants such as R-22, which are being phased out due to their harmful impact on the ozone layer.

One of the standout features of R-410A is its low impact on global warming potential, making it an environmentally-friendly choice. It is composed of a mixture of hydrofluorocarbons (HFCs), specifically difluoromethane (R-32) and pentafluoroethane (R-125). This blend allows for efficient heat transfer while minimizing harmful emissions, addressing the growing concerns over climate change.

Johnson Controls emphasizes the efficiency of R-410A systems, which can provide a highly effective cooling performance. They are designed to operate at higher pressures compared to R-22, allowing for more efficient heat exchange and better overall system performance. This results in greater energy efficiency ratings, contributing to lower electricity bills for consumers.

In terms of technology, R-410A systems often feature advanced compressor designs and enhanced coil configurations, which optimize the system’s performance. Johnson Controls integrates state-of-the-art variable speed technologies and smart controls that enhance responsiveness and adaptability to changing environmental conditions. These innovations not only improve thermal comfort but also reduce energy consumption, leading to a smaller carbon footprint.

Another significant characteristic of R-410A is its compatibility with various lubricants, which is crucial for maintaining system performance and longevity. Johnson Controls often utilizes specially formulated lubricants that work optimally with R-410A, ensuring reliable operation and reducing the risk of issues related to lubrication.

In summary, Johnson Controls R-410A is an important refrigerant characterized by its efficient, environmentally friendly properties and advanced technologies. Its application in modern HVAC systems provides users with excellent performance, substantial energy savings, and an effective solution for climate-conscious cooling. As the industry continues to evolve, R-410A remains a central player in the push toward more sustainable and efficient heating and cooling solutions.
