Bought to replace an older unit and upon receipt I found it is almost  1 1/2" shorter than the unit I removed which is OK as I was concerned because the old unit was a tight fit.  Not sure why it is shorter but I had to build a small platform for the unit to set op, good news the trim panel for the front will adjust to cover the platform so all is good. Last concern was the water fitting which is low on the front of the unit I was going to just bend the flex hose and run the water line under the unit as there is a channel for the water and power cable molded in the base. But I was concerned that the sharp bend would be too much for the hose so I had to had to purchase several fittings and some copper tubing to make a manifold to route the water line down and back in copper and them connect the flex hose. Because the unit is shorter here is limited room under the unit to rout stuff
