Posted Fri Nov 30, 2012, 9:38am Subject: Re: Giotto Premium Plus - Evoluzione - plumb in drip trays..
If the machine is designed to be plumed in, there will be a hole in the bottom of the drip tray, this hole is over the fitting that the drain hose attaches into.
The fitting is shaped like a bowl on top with a hole in the bottom or side that the drain hose attaches into. In any plumb in machine I have seen, there is no physical connection of the drip tray to the drain fitting. The drain fitting can be round, square or any combo of each. The hole in the drip tray is what controls the speed of the water draining through the drain system so a large catch basin in the drain fitting is not need.
I suspect in a machine that was built for both operations, there would be a rubber plug in the bottom of the drip tray so you can use it without the machine being plumbed in, by lifting it out and dumping it down a sink.
This is a drain box for an Elektra, as it was the first one I found a picture of. It is upside down and the open side of the box is facing away from you in the picture. You can see by the drain attach threaded fitting, the box is not large, this is typical as far as I have seen.
