FIG. 38 CHECKING ALIGNMENT
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.
