Installation and Control
The units are designed so that they can be exposed or enclosed in a bulkhead or ceiling void. The slimline nature of the units was part of the design which was undertaken in collaboration with Nicholas Hare Architects. When the units are exposed in the room or mounted in a bulkhead a grille is usually provided to direct air towards the ceiling and back of the room. The grille arrangement complies with the PSBP FOS. Exposed NVHR units can also be supplied with a fabric duct or solid duct.
