Attach the Release Handle and Cord
• Thread one end of the rope through the hole in the top of the
red handle so "NOTICE" reads right side up as shown.
Secure with an overhand knot at least 25mm from the end of
the rope to prevent slipping.
• Thread the other end of the rope through the link on the
emergency release cable.
• Adjust rope length so the handle is no higher than 1.8m
above the floor. Secure with an overhand knot. If the door is
greater than 2.5m in height the Release Cord Extension kit
accessory is required.
NOTE: If it is necessary to cut the rope, heat seal the cut end
with a match or lighter to prevent unraveling.

Pinning the Door

Use bolts or pop-rivets (not supplied) to hold the curtain to
the door drum.
1. Pull the release cord down and across to engage the ball into
the cup. Close the door manually. Pull the release cord across
and release to re-engage the opener.
2. Try to manually open the door with the opener engaged.
Any excess door curtain may balloon out from the top of
the drum.
3. To remedy any ballooning place gutter-bolts or pop rivets
(not supplied) 75mm up from where the curtain leaves
the roll. Secure these through the curtain into the
drum wheel at each end of the curtain.
