Where is the agreed layout?
Request drawings showing units, air routes and associated services. Coordinate them with lighting and other trades, including access for maintenance.
Does each route have a clear function?
Refrigerant pipework, condensate drainage and air ducts serve different purposes. Their dimensions and details follow the project design and selected model’s instructions.
What will be recorded before closure?
Agree on checks and responsibilities. Retain route photos, unit details and closed-out comments. These support future maintenance but do not replace on-site technical inspection.
