Back at Changi North, a 10HP ducted unit had to be replaced. 10HP in simple layman terms means about 90,000 BTU or 10 times the cooling capacity of a normal residential room aircon. The height of the aircon was at about 8-10 meters and we had to use a special type of forklift to reach those heights. Looking down from that height may give an individual sweaty palms or cause one to become nervous. This is why ample training is required to accustom technicians to be safe and condition them to be confident to work in such environments.
