Vacuum System Performance Test Pending Final Payment Email Template

Use this page when final payment is delayed because the buyer says the vacuum-system performance test, suction acceptance record, or vacuum-plant signoff is still pending. This is different from a general pump or process-mechanical page because it focuses on the demonstrated performance of the installed vacuum system under its required operating conditions. The commercial problem is that the plant may already be complete, but the payer is still holding the final balance until the performance test is approved. Your email should ask whether the vacuum-system test is the only remaining blocker, whether testing has already been carried out, what station, reading, or witness point is still unresolved, and whether payment will be released once that signoff is given. The outcome you want is to move the delay onto one exact vacuum-performance deliverable rather than generic mechanical closeout comments.
