What is the recommended practice for supporting horizontal refrigerant and drain lines?
a.Leave them unsupported
b.Support only at the equipment
c.Provide supports at intervals to prevent sagging and maintain proper drain slope
d.Bury them without protection
Explanation
Adequate, evenly spaced supports keep refrigerant lines from sagging and vibrating and maintain the continuous downward slope required for condensate drainage. Sagging drain lines create traps that hold water and cause overflow. Support intervals follow manufacturer and code guidance.
