first lower base tray, position it with
the lower edge along the fold line of
the bottom flashing. Ensure gap

mm – see Figure 57c. Fix to lower
middle batten as before using a
single screw – see Figure 57a.
Fit second upper base tray –
locating it into top of lower tray and
fixing to upper middle batten using
one of the self-drilling sealing
screws provided in the installation
kit at the centre of the upper edge –
see Figure 57b.
For installations using more than
two collectors, repeat the above
procedure to fit further lower and
upper base trays as necessary.
