fig. 7: Drainage holes
v) Drainage holes
There are eight drainage holes, 0.47 x 0.30 in (12 x 7.5 mm) in the panels frame, each spaced 2.2 in (55 mm) from the corner of the panel frame (fig.
5). This allows water caused by rain or snow melt to exit the frame easily and minimizes the damage caused by freezing and thawing. ensure these
holes are not covered by any part of the mounting structure.

When using mounting holes, fixings must be fastened to 9 ft-lbs (12 Nm) of torque and installation must be according to fig. 6.
Install the above parts as shown in fig. 6. Consult the Unirac Code Compliant Installation Manual for further details where necessary.
For areas where discrepancy may exist, this installation manual shall take precedence.
iii) mounting holes
Mounting utilizing the four elongated holes (0.26 x 0.43 in (6.6 x 11 mm)) on the underside of the panel frame (at a distance of 17.72 in (450 mm) from
the midpoint of the long side) have been found to comply with ul 1703 requirements for a maximum design load of 75.2 lbs/ft² (3600 Pa) (fig. 5).
when mounting using mounting holes, the frame and panel edge must be supported by two transverse rails (fig. 1, p 8),
of aluminium or galvanized
steel to avoid galvanic corrosion and be appropriate for the local environment. These must be
held in position by bolts and flange nuts according to
the specifications below. if bought in a kit, do not use the washers and bottom mounted clips provided:
observe the following procedures when using mounting holes (fig. 5):
•
additional electrical bonding to earth is required for the support structure (see page 12).
•
all four mounting holes in the frame must be used (for long or short-sided mounting orientation).
•
fixings must be tightened to
9 ft-lbs (12 Nm)
using a torque wrench.
The warranty will be voided if additional holes are made in the frame. All fixing and fastening materials should be corrosion resistant.
