Trane 4TWB3030 - Missing Support / Noisy

Trane Heat Pumps: 4TWB3030C1000A

Re: Missing Liquid Line Mounting Clip

Certain heat pumps have been shipped without a clip that secures the liquid line assembly to the cabinet.

If installed without a clip, the unit may generate unacceptable noise due to vibration. The vibration could also lead to tube cracking/fracturing which could result in the loss of refrigerant.
