Please consult your dealer for maintenance information and availability of maintenance contracts. Please read all instructions before installing the unit.

Outdoor Unit

Each outdoor unit is shipped with a refrigerant charge adequate to operate the outdoor section with an indoor matching coil or air handler.These units include the proper amount of refrigerant for an additional 15 ft. of refrigerant lines the same size as the valve fi ttings.

NOTE: DO NOT USE ANY PORTION OF THE CHARGE FOR PURGING OR LEAK TESTING.

Matching coils and air handlers may be shipped with a small holding charge to pressurize them to keep out contaminants.To release the pressure, read the indoor section installation instructions carefully.

Liquid and Suction Lines

Refrigerant grade copper tubing should be used when installing the system. Refrigerant suction line tubing should be fully insulated.

Field Connections for Electrical Power Supply All wiring must comply with current provisions of the “National Electrical Code” (ANSI/NFPA

70)and with applicable local codes having jurisdiction. The minimum size of electrical conductors and circuit protection must be in compliance with information listed on the outdoor unit data label.

SITE PREPARATION

Unpacking the Equipment

Remove the shipping carton and User’s Manual from the equipment.Take care not to damage the tubing connections when removing the carton.

Inspect for Damage

Inspect the equipment for damage prior to installing the equipment at the job site. Verify coil fi ns are straight. If necessary, comb fi ns to remove fl attened or bent fi ns.

Preferred Location of the Outdoor Unit Survey the job site to determine the best location for mounting the outdoor unit.Overhead obstructions, poorly ventilated areas, and areas subject to accumulation of debris should be avoided. The outdoor unit should be installed no closer than 18 inches from the outside walls of the facility and in an area free from overhead obstructions to ensure unrestricted airflow through the outdoor unit.

Facility Prerequisites

Electrical power supplied to the unit must be adequate for proper operation of the equipment. The system must be wired and provided with circuit protection in accordance with local building codes.

Minimum Circuit Ampacity

Electrical wiring to the equipment must be compatible and in compliance with the minimum circuit ampacity listed on the outdoor unit data label.

Maximum Fuse / Circuit Breaker Size Circuit protection for the outdoor unit must be compatible with the maximum fuse/circuit breaker size listed on the outdoor unit data label.

INSTALLING THE INDOOR UNIT

The indoor unit (air handler, furnace, etc.) should be installed prior to the routing of refrigerant piping. Consult the Installation Instructions of the indoor unit for installation details.

INSTALLING THE OUTDOOR UNIT

Slab Mount

The site selected for a slab mount installation requires a stable foundation and not subject to erosion. The slab should be level and anchored (if necessary) prior to installation on the slab.

Cantilever Mount

The cantilever mount should be designed with adequate safety factor to support the weight of the equipment, and for loads subjected to the mount during operation. Installed equipment should be adequately secured to the cantilever mount and levelled prior to operation of the equipment.

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.
