Slide the hanger bar up over the reflector retainer wire. Attach an “S” hook
at the center hole in the bar. Attach a turnbuckle or chain to the “S” hook.
Using a turnbuckle is recommended for leveling.
If the installation is going to be horizontal and a turnbuckle has been used,
close the “S” hooks. If the reflector is going to be angled or there is no turn-
buckle, leave the “S” hooks open until after the system is leveled.
