Which of the following best represents the recommended job-site prep before installing refrigerant lines?

Which of the following best represents the recommended job-site prep before installing refrigerant lines?

• A. Uncoil the tubing and immediately connect it.
• B. Plan to bend lines after installation.
• C. Install Ducts before refrigerant lines.
• D. Figure out the most practical way to run the lines, think about bends, determine the best starting point for routing lines inside and outside, ensure the tubing is long enough, uncoil the tubing without linking or denting, route the tubing and make all required bends, and secure it before making any connections.

Answer: (D)

The main idea is to plan and handle the refrigerant line-set thoroughly before any connections are made. You want a clear pre-install plan: figure out the most practical route for the lines, think about where bends are needed, determine the best starting point for routing inside and outside, and make sure the tubing is long enough to reach without forcing it. Then uncoil the tubing carefully, avoiding linking or denting, route and bend the lines as required, and secure them before making any connections. This sequence prevents damage, ensures proper fit and alignment, avoids kinks and leaks, and makes the system easier to service later. Rushing to connect or bending after installation increases the risk of damage and improper operation, so thorough planning and secure prep are essential.
