Refrigeration Installation

The line set and coil must be evacuated to at least 500 microns to remove any moisture and noncondensables. Evacuate the system through both service ports in the shipping position (full CW in - see table 5) to prevent false readings on the gauge because of pressure drop through service ports. A vacuum gauge or thermistor capable of accurately meausuring the vacuum depth is crucial in determining if the system is ready for charging. If the system meets the requirements in Figure 14, it is ready for charging.

NOTICE!

NOTICE! Use tables 14a to 15 for superheat/subcooling values. These tables use discharge pressure (converted to saturation temperature) and liquid line temperature for subcooling calculations. If using liquid line pressure, subtract 3ºF from the table values.

Charging The System

There are two methods of charging a refrigerant system. One method is the total charge method, where the volume of the system is determined and the refrigerant is measured and added into the evacuated system. The other method is the partial charge method where a small initial charge is added to an evacuated system, and remaining refrigerant added during operation.

Total Charge Method

See Table 4 for the compressor section basic charge. For line sets with 3/8” liquid lines add 0.6 ounces of refrigerant to the basic charge for every installed foot of liquid line [0.6 grams per cm]. Add 1.2 oz. per foot [1.1 grams per cm] if using

l/2” line. Once the total charge is determined, the factory pre-charge (Table 4) is subtracted and the remainder is the amount needed to be added to the system. This method should be used with the AHRI matched air handler or coil.

HTS SERIES specifications

The Heat Controller HTS Series is a cutting-edge solution for climate control, designed to offer superior performance and unmatched comfort. This advanced heating and cooling system stands out in today's market due to its innovative technologies and user-friendly features.

One of the main features of the HTS Series is its energy efficiency. Equipped with the latest inverter technology, it adjusts the compressor speed to maintain the desired temperature while consuming less energy. This not only reduces operational costs but also minimizes the carbon footprint, making it an environmentally friendly choice.

Another standout characteristic of the HTS Series is its precise temperature control. The system utilizes advanced sensors to monitor indoor conditions in real-time, ensuring that you experience consistent comfort throughout your space. The ability to quickly react to changes in temperature helps maintain an optimal environment, regardless of external weather fluctuations.

The HTS Series also boasts a robust air filtration system. With multiple filter layers, including HEPA filters, it effectively captures dust, allergens, and other airborne pollutants. This feature makes the HTS Series an excellent choice for families with allergies or respiratory concerns, promoting a healthier indoor atmosphere.

Furthermore, the heat pump technology incorporated in the HTS Series allows for both heating and cooling capabilities. In cooler months, it efficiently extracts heat from the outside air to warm your living spaces, while during the summer, it reverses the process to provide refreshing cool air. This dual functionality enhances versatility, making it suitable for various climates.

User convenience is paramount in the HTS Series design. It comes with a smart thermostat that enables remote operation via a mobile app, providing users with flexible control over their environment. Additionally, the intuitive interface and programmable settings allow for seamless customization, adapting to your daily schedule and preferences.

Durability and quiet operation are also key attributes of the HTS Series. Built with high-quality materials and components, it ensures long-lasting performance, while its sound-dampening technologies provide whisper-quiet operation, enhancing the comfort of your home or office space.

In summary, the Heat Controller HTS Series represents the pinnacle of home heating and cooling technology. With its energy efficiency, precise temperature control, superior air filtration, dual functionality, and user-friendly features, it stands as a leading choice for those seeking reliable and effective climate solutions. This series not only enhances comfort but also supports a sustainable lifestyle for the future.
