6.INSTALLATION WORK
6.1 PREPARING SHINGLE ROOF FOR INSTALLATION
1. Locate roof rafters or trusses.
Tip: here are 3 options to finding the locations.
A. Locate and measure the locations of the rafters in the attic or at the outside eave and transfer
measurements to the roof.
B. Use a rubber or leather mallet to tap the roof and locate the rafters. This will work with a cap sheet or
composition roof.
C. Scan the roof with a high sensitivity stud finder.
2. Once the rafters have been located, snap a chalk line on every rafter to identify the location.
3. Measure up from the eave 400 mm in at least 3 locations. Snap a chalk line. This marks the location of
the bottom edge of the slider feet.
Note: This line needs to be 5.5 mm away from the nearest front edge of shingles.
4. Measure up from chalk line 20 mm and snap a new chalk line. This marks the location of the bottom
edges of the modules.
5. Measure up from the module chalk line to the desired module length to form the array. Snap horizontal
lines at the measured locations.
6. Mark and layout solar module vertical lines.
Note: modules should not fall in shaded areas.
6.2 CHECKING LAYOUT
1. Before installing sliders, check layout of rails and splices.
2. Place all sliders in desired locations.
3. Pre-assemble rails and splices.
4. Place rails with splices into position. Ensure slider locations do not overlap splices.
5. If these overlap or seem too close, shift rails horizontally or move sliders to next rafter or remove splices
to switch the long and short rails to opposite sides. Reattach splices after rails are switched and recheck for
overlap.
6.3 INSTALLING THE FLASHINGS (OPTIONAL)
Flashings can improve water and ice management on the roof by directing the water around the rail slider
assembly. It is ideal for use in new construction, reroof,and in locations with significant precipitation. The
flashings are installed below the standard slider assembly. Each flashing is similar in size to the slider
assembly. The flashing has a large flange around it’s perimeter to allow for integration with the
surrounding shingles. There are 3 alignment marks on the flashing and identification for the orientation of
the part.
