board. For this anchor type also the rail fitting height can
be adjusted.
Installation
• Remove roofing in places where anchors shall be fitted
(Fig. 5). The distance “a” between anchors is defined
in Fig. 2.
• Cut the counter batten used for fastening the waterpro-
ofing membrane.
• Prior to the installation itself, use an underlay for
anchors according to the thickness of battens and
counter battens so that the anchors installed do not
hinder proper positioning of the roof tiles.
• Screw the adjustable aluminum anchor to a rafter and
move it in the groove horizontally so that it doesn’t
hinder proper positioning of the roof tile. If a fixed
stainless steel anchor is used, its position shall be
adjusted before faastening.
• Fit all the other roof anchors in the same way.
• When installing roof anchors, maintain a direction
parallel to the roofing (horizontal).
2.1.3 Installation with roof anchors for shin-
gle or metal roofs
• Depending on the number of collectors, measure and
calculate the positions for fiting roof anchors (Fig. 2).
Such places shall be selected for mounting where an-
chors can be fastened sufficiently into the roof frame
(rafter or similar).
• Prior to fitting the anchor, apply suitable silicone putty
on the contact surface (adjacent to the roofing) in or-
der to prevent water leaking, or possibly use a sealing
method recommended by the roofing manufacturer.
• Simply lay the anchor onto the roof tiles and fasten it
with stainless-steel bolts.
If the roofing is made of e.g. copper or zinc-pla-
ted iron, then the anchor contact surface shall be
isolated using suitable underlay (rubber). Other-
wise there is a risk of contact corrosion.
2.1.4 Installation using bolts for fitting rails
onto a roof
This method of installation is preferably used for roofs of
bitumen corrugated sheets like Gutta or Onduline etc., or
for corrugated eternit or metal sheets.
Installation:
• Depending on the number of collectors, locate the
places for drilling holes and installing bolts into the ro-
ofing (Fig. 7e). Pre-drill 6 mm diam. holes into a rafter
or another massive wooden roof element for the bolts.
Holes should be always drilled in the crest
of the roofing wave, not in its valley, to avoid
leakage.

• The bolt shall be screwed into a rafter or another
massive wooden roof element using spanner No. 7.
• After screwing the bolt in, put on the rubber seal and
using a washer and nut, seal the drilled hole.
• Then mount the U-shaped bracket on the bolt, be-
tween two nuts with a serrated washer.
• Then M8 bolt with floating head (for rails) shall be
mounted into the other end of the bracket. First insert
the floating head into the groove of the rail, and then
tighten the bolt together with the rail to the U-shaped
bracket using a nut and a serrated washer.
