Abstract
Abstract The means and method of pitching a refrigeration evaporator toward its drain outlet which includes a top plate of variable thickness. The evaporator is secured to the top plate. When the top plate is secured against the horizontal ceiling, the evaporator is caused to pitch, so that condensate leaving the coil and entering the drain pan flows directly to the drain fitting which is positioned under the portion of the top plate having the greatest thickness.
