The shrieking noise reported by various people turns out to be due to a dry bearing. The engineer replaced a very hard to get at unit but that was just as bad.
Best thing is to cut a hole in the left had side and oil the bearing. Works a treat - piy about the hole.
Now a seal has failed on the condenser unit and we are getting copious quantities of water into the room rather than the reservoir.
