FITTING OF WIND WALLS

1. Prior to fitting flashing, the following steps in installation should
have taken place: (a) Basin(s) placed in position and shimmed to
make level and carry weight evenly. (b) Casing lowered onto basin
legs and the leg joiners bolted together.
2. With the casing bolted to the basin, seal the joints between the posts.
3. There are two flashing pieces provided for each side of the unit.
Each flashing piece rests on the fiberglass ledge of the basin
wind wall. The wind wall is not fully glued to the post and can
be temporarily pulled away from the post to slide the flashing in.
Each flashing piece has a folded end to prevent water falling out.
When the flashing is in the correct place, this folded end is sealing
against the outside face of the corner post. The flashing pieces
overlap by approximately 30mm. They are not designed to be
bolted together.
4. To fix the flashing in position, screw the Z-section brackets to
the flashing pieces so as to pull the flashing against the upper
fiberglass panel. Sealer is applied to the fastener as it is fitted to
prevent water migration through the fastening points.
5. When the flashing is in place, there is a cavity created behind the
corner posts and sealing is required within this area. (a) Use the
sealer provided to seal the bottom horizontal corners behind the
post. (b) Seal the vertical joint between the post and flashing ends.
6. Seal the vertical joint where flashing pieces overlap each other.
7. It is not envisaged that sealing is needed on any of the other
horizontal joints such as where flashing overlaps fiberglass panels.
