5. Insert probe wires through o-ring and black plastic probe cover. Push the cover against the
collector frame over the copper end of the probe. Fasten the cover with the two self-drilling screws
(Fig.6.1.10).
Mounting brackets secure collectors to C-channel. Two types of mounting brackets are available: hook
brackets and L-brackets. Hook brackets are used for mounting to C-channel. L-brackets may be used
for rack-mounting (hook brackets may be used for rack-mounting if C-channel is secured to rack).
Bracket mounting points are 24” (610 mm) from ends of collector on long sides and 48” (1220 mm)
apart, center to center.
Hook Brackets
Hook bracket kit consists of upper and lower brackets. Upper hook brackets are left and right specific.
Lower brackets are not side specific (Fig. 6.1.11).
Upper brackets feature a unique tab that fits into C-channel to support collector weight before securing.
Tab also allows collector to slide, side to side, in C-channel. Upper brackets also feature loops for
attaching carabiners and/or line to assist with hoisting.
With collector lying flat or on long edge (but not on glass edge), and resting on soft, smooth surface,
attach four brackets with bolts and washers (Fig. 6.1.11).
Upper brackets with loop and tab (hook) are towards top (with stagnation-control device). Loops must
be closest to top of collector (Fig. 6.1.11). Use ratchet or driver with a ½” socket. Do not overtighten
(maximum torque of 9 ft·lb or 12.2 N·m). Lower brackets are towards bottom (with intake grill).
