1 Solar collector racking system NS100 series CCREITE ISO 9001 FM ISO 9001 No CLEFFI 01281/14 N Replaces 01281/13 N The collectors must be mounted to two horizontal NS100 series four slot rails. The frame will accept the collector clip (in code NS10006 or NS10007 kits) mounted along the collector sides without drilling or tapping so the integrity of the frame wall is not compromised. The NS100 series four slot rail has four 9/16" slots which accept standard stainless steel 3/8" bolts and nuts for mounting collector clips and U-mounts to flashing. The NS100 series aluminum 6005-T5 four slot channel rail can span 7 feet in moderate wind and snow loads installations. The NS " U-mount mounts directly on top of NS10030 roof flashing with a 3/8" standard stainless steel nut and attaches into the side slots of the NS100 series rail using NS10042 stainless steel 3/8"-16 x 1" bolts, nuts & washers.

If the collector array is mounted with the side edge within 3 feet of the eave, which is in the edge zone, the individual collector mounted within the edge zone must comply with the edge zone maximum span s between supports as specified in the above table. Refer to the above NS100 series four slot rail maximum span table for the maximum span between the supports. Cantilever is not exceed 18".

3 NS10006 tilt mounting kit Caleffi s NS10006 mounting kit allows collectors to be tilt mounted. Collectors may be mounted to any roof, vertical wall, fascia board, pre-constructed rack or ground mount system. The collectors must be mounted to two horizontal Caleffi NS100 series four slot rails or any U type rails (see illustration). The four slot rail collector frame wall will accept the collector clip mounted along the collector sides without drilling or tapping so the integrity of the frame wall is not compromised. The optional rear extension tubes can be cut to length allowing proper elevation and orientation. Pivot shoes and collector clips are mill finshed and extruded from high tensile strength 6005-T5 aluminum. ll stainless steel bolts, nuts and washer are made of 304 stainless steel materials and certified to STM F593C and STM F594C standards. Tilt mounting The tilt mounting kit allows for the collectors to be angled differently than the orientation of the surface they are secured to. This is achieved by placing two rails to the back of the collector and attaching the collector clips, pivot shoes and U-mounts included in hardware kit shown below. The mounting rails and tilt extension tubes are available separately.

4 NS10007 flush mounting kit Caleffi s NS10007 mounting kit allows collectors to be flush mounted to any elevated surface or ground mount system. The collectors must be mounted to two horizontal Caleffi NS100 series four slot rails or suitable U type rails (see illustration). The four slot rail collector frame wall will accept the collector clip mounted along the collector sides without drilling or tapping so the integrity of the frame wall is not compromised. Collector clips are mill finished extruded aluminum from 6005-T5 high tensile strength aluminum. ll stainless steel bolts, nuts and washer are made of 304 stainless steel materials and certified to STM F593C and STM F594C standards. Collector clip The tilt and flush mounting kits contain collector clips which have a unique concave shape with a hole in the center that when tightened, with supplied 3/8"-16 x 1" stainless steel bolt to rails, tension is formed on the bolt nut which keeps clip fastened securely. Flush mounting The flush mounting kit allows for parallel mounting on a sloped roof surface. This is achieved by placing two mounting rails to back of the collector and attaching with collector clips included in hardware kit shown below. Mounting rails and U-mount 2" are available separately.

The attractive low profile design (3/4") allows mounting closer to the roof and works well with racking systems. The simple design has fewer components to minimize installation labor. Water stays out because there are no exposed rubber or threads. llows compatibility with any racking and standoff components, for simpler more cost effective installation. The NS10030 flashing kit inclues 3/8" stud for attaching U-mounts and other brackets using the supplied 3/8" stainless steel nut & washer. lack painted aluminum (6061-T6) flashing 14-3/4"L x 9-1/2"W x 0.6"H, galvanized steel base plate with six mounting holes and double stud.
