BS box replacement.
Dunn AC were appointed the contractor to replace numerous branch selector (BS) boxes throughout the building that had failed.
Recovery of complete refrigerant circuits was carried out and BS boxes removed and replaced. Once completed the systems were fully pressure tested, evacuated and re-charged with the correct volume of refrigerant, fully tested and commissioned.
Our task was to complete the works on a strict deadline with partial out side of normal working hours.
Full operation and maintenance manuals, test and commissioning certification and user training followed the successful completion.
