Harmonic Filter Tuning Report Not Approved Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the harmonic filter tuning report, filter-tuning acceptance record, or tuned-filter signoff still lacks approval. This is different from a general harmonic distortion test page because the blocker here is the verified tuning and adjustment of the installed filter equipment itself. The commercial problem is that the system may already be energized, but the payer is still withholding payment until the tuning evidence is accepted. Your email should ask whether the harmonic filter tuning report is the only remaining blocker, whether tuning has already been completed, what filter bank, resonance point, or tuning value is still unresolved, and whether payment will be released once that report is approved. The outcome you want is to tie the delay to one exact filter-performance deliverable instead of broad comments about incomplete power-quality optimization.
