FAQ

What is a commissioning certificate?

A commissioning certificate is a document signed by the installer confirming that the equipment was installed correctly, tested, and is operational. It typically starts the warranty period and is essential for warranty claims.

Should I be present during installation?

Yes, if possible. Being present allows you to observe the process, ask questions, take photos, and note any concerns. If you cannot be present, designate a representative and ensure they document the installation.

What if the installer won't provide written documentation?

Request it in writing via email. If the installer refuses, document the request and the refusal. This creates a record that you sought documentation. Consider it a red flag for future disputes.

How do I document installation issues?

Take photos, write a description of the issue, note the date and time, and send an email to the installer describing the problem and requesting a fix. Keep all responses. Do not attempt repairs yourself unless authorized.

What records matter most for warranty purposes?

The commissioning certificate, warranty registration confirmation, installation report, and any service records. These establish that the equipment was properly installed and commissioned, which is typically required for warranty coverage.
