Pipe forming / positioning

•Pipe forming.

Form the pipe along with a marked line of the cabinet.

•End positioning of pipe.

Match the ends of both pipes at a distance of 85 mm apart from the marked line.

2.Insert a flare nut into the pipe, and flare the pipe.

As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newly manufactured for R410A are recommended.

•In case of flaring for R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that of R22 to adjust to the specified flare size.

The copper pipe gauge is useful for adjusting projection margin size.

lign the centres of the connecting pipes and tighten the flare nut as strong as possible with your fingers.

Then fix the nut with a spanner and tighten it with torque wrench as shown in the figure.

•As shown in the figure, use two spanners to unscrew or tighten the valve flare nut, at gas side.

If using a single spanner, the nut cannot be tightened with necessary tightening torque.

On the contrary, use a single spanner to loosen or tighten the flare nut of the valve at liquid side.

REQUIREMENT:

1.Do not put the spanner on the cap. The valve may be broken.

2.If applying excessive torque, the nut may be broken according to some installation conditions.

•After the installation work, be sure to check gas leak of connecting part of the pipes with nitrogen.

Cover

•Pressure of R410A is higher than that of R22 (Approx. 1.6 times). Therefore, using a torque wrench, tighten the flare pipe connecting sections which connect the indoor/outdoor units at the specified tightening torque.

Incomplete connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

IMPORTANT:

Do not apply refrigerating machine oil to the flared surface.

38VYX080, 38VYX050 specifications

The Carrier 38VYX050 and 38VYX080 are innovative heating, ventilation, and air conditioning (HVAC) units designed for both residential and commercial applications. These models are part of Carrier's extensive product line, renowned for combining efficiency, reliability, and advanced technology to meet diverse climate control needs.

One of the standout features of the 38VYX series is its high efficiency. Both the 38VYX050 and 38VYX080 are engineered with a variable-speed compressor, allowing them to adapt to the specific cooling demands of the environment. This capability not only ensures optimal comfort but also enhances energy savings, reducing overall operational costs and environmental impact. With excellent SEER ratings, these units are compliant with stringent energy efficiency standards, making them an eco-friendly choice.

The two models also incorporate advanced inverter technology, which allows the system to start slowly and gradually ramp up to the desired cooling capacity. This results in quieter operation compared to traditional HVAC systems while significantly reducing energy consumption during less demanding times. Additionally, their low noise levels make them ideal for use in noise-sensitive environments such as residential areas, schools, and healthcare facilities.

Another feature of the Carrier 38VYX050 and 38VYX080 is the use of a top-mounted air discharge, optimizing airflow throughout the space and enhancing cooling efficiency. Furthermore, both models are designed with a durable cabinet that can withstand harsh weather conditions while ensuring low maintenance needs over their lifespan.

The comprehensive control options available for these units make them user-friendly and convenient. They can be integrated with smart thermostats and home automation systems, allowing for remote access and control via smartphones or tablets. This connectivity ensures that users can easily adjust settings or monitor energy usage from virtually anywhere.

Safety features are also a significant consideration in the design of the 38VYX series. Equipped with advanced refrigerant management systems and multiple safety switches, these units help prevent potential issues, ensuring reliable operation over time.

In summary, Carrier's 38VYX050 and 38VYX080 HVAC units offer exceptional energy efficiency, advanced technology, and user-friendly controls. Their reliable performance and robust safety features make them an excellent choice for those seeking high-quality climate control solutions.
