Installation Guide
Allow the light guide to cool by natural convection or lightly forced cool air (i.e. fan). Remove the Bend-Aids for reuse. In order to remove any
minor surface flaws, perform a light sanding using 400 grit sandpaper. Flared or deformed ends can be trimmed. The light guide is now ready
for light engine installation.
Note:
DO NOT remove the Bend-Aids until the light guide has completely cooled.
Note:
DO NOT subject heated light guide to freezing or quenching in water.
Option A: Large Bends
Heat gun
r
Preheat the heating equipment to
300°F (149°C). Heat light guides
approximately 6-15 minutes until
soft and pliable. Bend the light
guide over a printed pattern, routed
template, or use free-forming. A
clean flat insulated surface (wood
or laminated countertop) will help
to prevent twisting or bowing. See
the chart above for minimum bend
radius guidelines.
Part 1: Move the section back and
forth while rotating about the
diameter until it is soft and pliable.
Gently bend to the desired angle.
It is recommended to use a
heatdeflecting shield to distribute
the heat evenly. Avoid localized
overheating that may result in
distortion or damage (i.e. bubbling) of
the light guide.
Part 2: The workable forming time is
about 2–3 minutes. The light guide
must remain in the desired position
until completely cooled. See the chart
above for minimum bend radius
guidelines.
Heating and Forming
Step 2:
CAUTION/ATTENTION
Avoid direct contact between hot materials and exposed skin or combustibles. Use heat
resistant gloves while heating and/ or handling any hot materials. / Éviter tout contact direct des parties
chauffées avec la peau ou d’autres matières combustibles. Utiliser des gants de protection thermique
lors du chauffage ou de toute manipulation des pièces chauffées.
For large bends, use either an
industrial oven or heating blanket.
For small bends, use a heat gun.
CAUTION/ATTENTION
DO NOT use an open flame to heat the light guide. /
Ne pas utiliser une flamme nue pour chauffer le guide.
