Refrigeration Installation

CAUTION!

CAUTION! R-410A systems operate at higher pressures than R-22 systems. Be certain that service equipment (gauges, tools, etc.) is rated for R-410A. Some R-22 service equipment may not be acceptable.

CAUTION!

CAUTION! Installation of a factory supplied liquid line bi-directional filter drier is required. Never install a suction line filter in the liquid line.

Line Set Installation

Figures 12a through 13b illustrate typical installations with the “indoor” and “outdoor” versions of the compressor section matched to either an air handler (fan coil) or add-on furnace coil. Table 4 shows typical line-set diameters at various lengths. Lineset lengths should be kept to a minimum and should always be installed with care to avoid kinking. Line sets over 60 feet [18 meters] long are not recommended due to potential oil transport problems and excessive pressure drop. If the line set is kinked or distorted, and it cannot be formed back into its original shape, the damaged portion of the line should be replaced. A restricted line set will effect the performance of the system.

A reversible heat pump filter drier is installed on the liquid line inside the compressor section cabinet (R-22 units only). R-410A models are shipped with a filter drier (loose) inside the cabinet that must be installed in the liquid line at the line set. All brazing should be performed using nitrogen circulating at 2-3 psi [13.8-20.7 kPa] to prevent oxidation inside the tubing. All linesets should be insulated with a minimum of 1/2” [13mm] thick closed cell insulation. All insulation tubing should be sealed using a UV resistant paint or covering to prevent deterioration from sunlight.

When passing refrigerant lines through a wall, seal opening with silicon-based caulk. Avoid direct contact with water pipes, duct work, floor joists, wall studs, floors or other structural components that could transmit compressor vibration. Do not suspend refrigerant tubing from joists with rigid straps. Do not attach line set to the wall. When necessary, use hanger straps with isolation sleeves to minimize tranmission of line set vibration to the structure.

Installing the Lineset at the Compressor Section

Braze the line set to the service valve stubs as shown in Figure 10. On installations with long line sets, copper adapters may be needed to connect the larger diameter tube to the stubs. Nitrogen should be circulated through the system at 2-3 psi [13.8-20.7 kPa] to prevent oxidation contamination. Use a low silver phos-copper braze alloy on

all brazed connections. Compressor section is shipped with a factory charge. Therefore, service valves should not be opened until the line set has been leak tested, purged and evacuated. See “Charging the System.”

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.
