After commissioning
After the commissioning visit has taken place the engineer will return the paperwork to GDC Group for our Technical Services Department to review and based on the engineers observations the installation will either:
- receive extended warranty,
- receive extended warranty with an addtional advisory note
- be refused extended warranty.
In each case the notification will be emailed to the person who requested the commission.
The refusal and advisory notes detail the reasons for failure or outline the aspects of your installation which may present a problem in the future.
