Hi..I promise that this is genuine...one of our management was doing a favour for a big customer of ours while he was in a particular area by surveying a small workshop office in london...he found a ceiling mounted cassette unit which the office manager said had been installed for two years....he also stated that the unit seemed to work fine in the winter but was not very efficient in the summer.
The fan was blowing fine ...so ...curiosity aroused our guy utilised a set of steps in the workshop and popped out a ceiling tile between the cassette and the outside wall(there were another eight floors above)..he found a pair of pipes which came through the outside wall but were not connected to anything...he called down to the manager ...that here is the problem....your unit is not even connected....he then gave the pipes a slight tug and they came free from the wall and were loose in his hand????....it gets better
The manager said....no you are mistaken...the guys who fitted it had some sort of problem with the piping so they connected it directly to the water supply...he indicated a sink on the wall of the workshop..wherein there was a tap with a hose connecter attached...the hose running up the wall and into the celing void.....there was another hose taped to the first one which ran back down the wall and was open to the sink???
Are you getting it yet??....our guy pulled off another couple of tiles and there was the liquid line....sawn off upstream of the TEV...hose attached.....the suction outlet was also sawn off and the drain hose fitted with a jubilee clip....the guy had been told that because of the "problems" the installers had had that when he wanted to run the AC he had to turn the tap on....this put mains water through the DX coil with the fan blowing across gave some sort of cooling effect in the winter when the mains was quite cool but was less efficient in the summer when the mains water temperature rose considerably???...the water then ran back into the sink to drain.
The "installers" had obviously disappeared off the face of the earth....is this a candidate for the hall of infamy??
Regards Superheatman.
