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

Brackets (parts list Item 1)

2Verify spring tension in the Night Curtain (parts list

The night curtain spring is
properly tensioned at the time

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 2A), 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.
