Illustration depicts an M3X-12EP
with three Night Curtains installed.
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.
1Remove the left fascia panel
first, then remove the fascia
panel to the right of the first
panel. Continue until all fascia
panels are removed.
2Remove the bottom canopy
extrusion:
A. Rotate the bottom edge of
extrusion to unsnap it from the
supports.

Note: Night Curtain
Brackets (parts list Item 1)

3Verify spring tension in the
Night Curtain (parts list
Item 2).
The night curtain spring is
properly tensioned at the time
of shipment but may unwind
due to vibration or rough
handling.
To tension the spring, use the
supplied Wrench (parts list
Item 3) on the rectangular pin
on the RH end of the curtain
(as shown in Detail 3A), then
make 10 to 12 full clockwise
revolutions.
After passing the detent, gently
tap on the end. Slowly release
pressure against the spring until
the wrench stops, then remove
the wrench. Handle tensioned
curtain carefully.
