Section III Unit Installation | Johnson Controls 13 SEER

1031452-UIM-B-0513

LIMITATIONS

The unit should be installed in accordance with all National, State and Local Safety Codes and the limitations listed below:

1.Limitations for the indoor unit, coil, and appropriate accessories must also be observed.

2.The outdoor unit must not be installed with any duct work in the air stream. The outdoor fan is the propeller type and is not designed to operate against any additional external static pressure.

3.The maximum and minimum conditions for operation must be observed to ensure a system that will give maximum performance with minimum service.

TABLE 1: Application Limitations

The outdoor unit must have sufficient clearance for air entrance to the condenser coil, air discharge, and service access. See Figure 1.

NOTICE

For multiple unit installations, units must be spaced a minimum of 24 inches apart (coil face to coil face).

If the unit is to be installed on a hot sun exposed roof or a black-topped ground area, the unit should be raised sufficiently above the roof or ground to avoid taking the accumulated layer of hot air into the outdoor unit.

Provide an adequate structural support.

5.The maximum allowable line length for this product is 75 feet.

SECTION III: UNIT INSTALLATION

LOCATION

Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements.

ADD-ON REPLACEMENT/RETROFIT

The following steps should be performed in order to insure proper sys- tem operation and performance.

1.Change-out the indoor coil, if required, to an approved R-22 coil/ condensing unit combination with the appropriate metering device.

2.If the outdoor unit is being replaced due to a compressor burnout, then installation of a 100% activated alumina suction-line filter drier in the suction-line is required, in addition to the factory installed liquid-line drier. Operate the system for 10 hours. Monitor the suction drier pressure drop. If the pressure drop exceeds 3 psig, replace both the suction-line and liquid-line driers. After a total of 10 hours run time where the suction-line pressure drop has not exceeded 3 psig, replace the liquid line drier, and remove the suction-line drier. Never leave a suction-line drier in the system longer than 50 hours of run time.

FIGURE 1: Typical Installation

GROUND INSTALLATION

The unit should be installed on a solid base that is 2” above grade and will not shift or settle, causing strain on the refrigerant lines and possible leaks. Maintain the clearances shown in Figure 1 and install the unit in a level position. The base pad should not come in contact with the foun- dation or side of the structure because sound may be transmitted to the residence.

The length of the refrigerant tubing between the outdoor unit and indoor coil should be as short as possible to avoid capacity and efficiency losses. Excessive spacing of the outdoor unit from the home can result in the refrigerant lines being restricted by trampling or being punctured by lawn mowers. Locate the outdoor unit away from bedroom windows or other rooms where sound might be objectionable.

Adverse effects of snow or sleet accumulating on the outdoor coil can be eliminated by placing the outdoor unit where the prevailing wind does not blow across the unit. Trees, shrubs, corners of buildings, and fences standing off from the coil can reduce capacity loss due to wind chill effect.

Provide ample clearance from shrubs to allow adequate air to pass across the outdoor coil without leaves or branches being pulled into the coil.

ROOF INSTALLATION

When installing units on a roof, the structure must be capable of sup- porting the total weight of the unit, including a pad, lintels, rails, etc., which should be used to minimize the transmission of sound or vibra- tion into the conditioned space.

13 SEER - GCGD specifications

Johnson Controls has long been recognized as a leader in the HVAC industry, and their 13 SEER - GCGD model encapsulates the company's commitment to energy efficiency, innovation, and user comfort. The GCGD, designed for residential applications, offers a balanced combination of performance and value, making it an excellent choice for homeowners looking to enhance their indoor environment.

One of the standout features of the 13 SEER - GCGD is its Seasonal Energy Efficiency Ratio (SEER) rating of 13, which categorizes it as an energy-efficient cooling system. This rating translates to substantial energy savings when compared to older, less efficient units, allowing users to reduce both their environmental impact and utility bills. Moreover, this unit is designed to perform efficiently in a variety of weather conditions, ensuring reliable cooling throughout the peak summer months.

At the heart of the GCGD is its advanced scroll compressor, known for its quiet operation and durability. This technology minimizes noise disturbances while efficiently compressing the refrigerant to optimize cooling performance. Additionally, the unit incorporates a compact design, allowing for easier installation in tight spaces, making it suitable for various residential settings.

Another significant characteristic of the GCGD is its use of high-quality components, including a robust cabinet construction designed to withstand the elements. This ensures long-term reliability and protection against outdoor conditions, thus extending the lifespan of the unit. The use of corrosion-resistant materials further enhances durability, reducing maintenance needs and costs over time.

The GCGD also features user-friendly controls, which enable homeowners to easily set their desired temperature and operating mode. Optional smart thermostats can be integrated, providing advanced control and energy management solutions that cater to modern lifestyle requirements. This compatibility with smart technology aligns with the growing trend towards home automation, allowing homeowners to manage their comfort efficiently.

In summary, Johnson Controls' 13 SEER - GCGD model offers an appealing solution for those in search of an energy-efficient and reliable air conditioning system. With its optimal SEER rating, advanced compressor technology, robust construction, and user-friendly design, the GCGD stands out as a practical choice for households looking to enhance their cooling capability while being mindful of energy consumption. This model not only promises comfort but also contributes positively to a sustainable future.
