Hello, I have a few questions regarding how to demonstrate the amount of refrigerant charge. The questions are as below.

1. Situation
We are preparing design phase review. According to the load calcualtion, we ordered mechanical equipments.
2. Questions
1) should product catalogs or brochures be submitted? In my LEED project, some building mechanical equipments were made to order. Threfore, there is no product catalog except few mechanical equipment like chillers, heat pumps. But, we have documents that indicate some information such as refrigerants charge, model number, refrigerant type from our manufacturer.
I am just wonderign if this document would be helpful for earning this credit.
Thank you for your help in solving this problem.
