Notes: Night curtains are intended to
reduce energy use outside normal
business hours.
Carefully unpack and inspect the
night curtain and components
to ensure there is no breakage or
damage, and there are no missing
parts.
Be sure cases have been positioned
and leveled according to installation
instructions. Install night curtains
after all cases are joined, and splash-
guards and bumpers are installed.

extrusion to unsnap it from the
supports.
