6.3 Securing Collectors to C-Channel
1. Lift first collector and place its upper bracket hook tabs into C-channel such that weight of collector is
fully supported by C-channel.

then be connected to control wire before other collectors are in place.
2. Slide first collector into position and secure with supplied
bolts, washers and twirl nuts (Fig. 6.3.1).
Maximum
torque of 9 ft·lb or 12.2 N·m.
3. Lift second collector (if applicable) into position, placing
upper bracket hook tabs into C-channel. Slide second
collector far enough away from first collector to install
upper custom flare fitting union.
4. Connect custom flare fitting union to upper copper tube
emerging from side of second (unsecured) collector.
Connect flare fitting 90
to lower copper tubes
from collectors; angle down until line set is run.
5. Carefully slide unsecured collector towards first (secured)
collector such that custom flare fitting union reaches f i r s t
collector’s upper tube. Tighten flare fitting connections.
