Page 17: Unit Clearance Requirements
400mm clearance may be suitable on the pipework side depending on the system arrangement. The Artus unit is designed for a very low pressure drop on the air side and an appropriate return air path must be provided when used in a false ceiling. Without this the fan duty may reduce, the specific fan power may increase, and the noise may increase. - Page 18 400mm clearance may be suitable on the pipework side depending on the system arrangement.
