board. For this anchor type also the rail 

fi

 tting height can 

be adjusted.

Installation

•  Remove roo

fi

 ng in places where anchors shall be 

fi

 tted 

(Fig. 5). The distance “a” between anchors is de

fi

 ned 

in Fig. 2. 

•  Cut the counter batten used for fastening the waterpro-

o

fi

 ng 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 

fi

 xed 

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 roo

fi

 ng (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 

fi

 ting roof anchors (Fig. 2). 

Such places shall be selected for mounting where an-
chors can be fastened suf

fi

 ciently into the roof frame 

(rafter or similar). 

• Prior to 

fi

 tting the anchor, apply suitable silicone putty 

on the contact surface (adjacent to the roo

fi

 ng) in or-

der to prevent water leaking, or possibly use a sealing 
method recommended by the roo

fi

 ng manufacturer.

•   Simply lay the anchor onto the roof tiles and fasten it 

with stainless-steel bolts. 

If the roo

fi

 ng 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 fi tting 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-
o

fi

 ng (Fig. 6e). 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 roo

fi

 ng wave, not in its valley, to avoid 

leakage.

•  The bolt shall be screwed into a rafter or another 

massive wooden roof element (see 2.2.3) using spa-
nner No. 7. 

•  After screwing the bolt in, put on the rubber seal (Fig. 

6e) and using a washer and nut, seal the drilled hole. 

•  Then mount the U-shaped bracket  (Fig. 9) on the 

bolt, between two nuts with a serrated washer. 

•  Then M8 bolt with 

fl

 oating head (for rails) shall be 

mounted into the other end of the bracket. First insert 
the 

fl

 oating 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.
