When in its proper position, the cooling drum will cause a slight pressure on the hopper drip tray drain hole and the two legs will be equidistant from the hopper drip tray.

If adjustment is needed, remove the support and gently force the free end of the evaporator in the direction the adjustment is needed.

Reinstall the support, check the alignment, and readjust the cooling drums as required.

Never try to remove the cooling drums (4 screws) unless trained refrigeration technician is replacing the evaporator assembly.
