EURO C20/C22 On-Roof Installation
Figure 1 The EURO-collectors can easily be installed by two people with no need to remove any part of the roof or for soldering.
The EURO collector on-roof system can be installed quickly
practically without having to remove the cladding. The col-
lectors are available in two sizes, EURO C20 and EURO C22.
They can be installed either horizontally or vertically and
the collector field can be positioned independently of the
roof rafters.
You will need two ventila-
tion or roof passage tiles
for the pipe passage.
All components are weather resistant including the piping
insulation which is made of UV and bird resistant material.
The collectors can be installed by two people with normal
tools and with no need for soldering.

Figure 5 Roof brackets and their dimensions
The Connection with the Roof
The on-roof system comprising roof brackets, mounting
rails and hammerhead bolts ensures that the collectors are
securely fixed to the roof (figure 4). The roof brackets are
fixed to the roof rafters with dry wall screws (6x80 mm).
Where this is not possible, e.g. with corrugated sheeting,
6x8 cm joint beams should be used to create a support.
Mounting rails are connected to the roof brackets with
hammerhead bolts. A tight connection is guaranteed once
the bolt head sits square with the slot. The slot on the base
of the screw indicates the position (figure 4). The collectors
are fixed to the mounting rails with fastening clips.
There are various types of roof brackets to ensure a good fit
with different types of tiles. For example type P for inter-
locking tiles, type W for corrugated sheets or fiber cement
and type S for flat tiles and slate (figure5-8).
The number and position of the roof brackets depending
on the number of collectors is shown in figures 10 and 11.
For roofs with on-roof insulation of the rafters we provide
the Torx screws 7x270 Twin AD.

as the laths) to the rafters, then position the roof brackets and fix them
with spax screws.

Figure 13 Tools for installation: carpenter’s gauge, drill, screwdriver bit
(cross recess PZ 3), open-ended spanner – sizes 16, 19 and 24 (mm).
Figure 15 Please ensure that when tightening the bolts the nut sits
square with the long side of the railing. This is important for the fitting
accuracy of the collector.
Figure 14 Prepare the installation railings on the ground. Insert the
hammerhead bolts into all holes in the installation railings from inside
and fasten the nuts.
Figure 16 Connect collector railings (➃, p. 2) and expansion collector
railings (➄,p. 2) with coupling piece using two hammerhead bolts. Push
the railings tightly together.
Installation
Please observe the following guidelines before
commencing work and during installation.
You will find some important notes about accident preven-
tion in the leaflet “Safety instructions for collector installa-
tion”.
If collectors have to be stored outside, this can be done in
two ways:
1. Lay down collectors with glass up. Avoid direct ground
contact, e.g. by laying wood beams under collectors. Put
spacers such as wood laths between collectors to avoid
scratches on the glass.
2.Lean collectors with their rear side against a wall or some-
thing similarly solid. Place spacers between collectors.
Don't lay paper or cardboard between collectors. Incorrect
storage can result in humidity entering the collectors.
Prevent damage from frost!
It is not possible to empty collectors completely after pres-
sure testing and rinsing. It is therefore necessary to fill the
system with antifreeze immediately. The volume for one
collector is 1.3 litres of the required mix. Check the concen-
tration level with a frost protection meter. Do not leave pure
water in collectors if there is danger of frost!
We do not accept any responsibility for damages resulting
from not adhering to these instructions.
It is mandatory to follow best practice rules for static plan-
ning, especially those related to wind and snow loads. Dif-
ferent codes and regulations apply in different countries
and regions. For more information please refer to the tech-
nical information “EURO Solar Collector“ C20/C22 and the
leaflet “Notes on Snow and Wind safe Installation of Solar
Collectors“.

Figure 17 When installing the collectors vertically, you should insert
the two on-roof collector holders before connecting the rails and posi-
tion them to the left and right of the coupler.
Figure 18 When working on the roof please observe the guidelines set
out in the “Safety instructions for collector installation” leaflet.
Figure 19 Measure the area for the collector on the roof and determine
the corresponding fastening points on the roof.
Figure 20 Fix the roof brackets with self tapping screws (6x80). If the
laths are thicker than 30 mm then put a support under the roof brackets.
Figure 21 Align the collector rails at the same height and fix to the roof
brackets with screws so that when tightly fastened, the bolt head lies
perpendicular to the rail.
Figure 22 Carrying handles can be provided on request. Fasten them
to both sides of the collector at the top edge of the collector with fasten-
ing clip (see figure 2) – Check that they are tight.

EN-EURO-C20-C22-On-Roof-Installation-MA-0704-11211100 7
Figure 23 Place the collector onto the two lower bolts of the collector
rails.
Figure 24 Fix the collector to the bottom and top edges with fastening
clips so that the engraved arrow points towards the collector (see close-
up page 2).
Figure 25 Push the bottom edge of the lower collector under the fas-
tening clips and tighten the lower fastening clips so that the arrow
points to the collector.
Figure 26 Only for vertical installation put the collector in the on-roof
collector holder first.
Figure 27 Only for vertical installation then fix the collector with fasten-
ing clips so that the engraved arrow points towards the collector. Then
install the next collector.
Figure 28 Option: Slide or push t-section silicone into the gap be-
tween two collectors.

Figure 29 Pull the plug from the sensor sleeve and push over the sen-
sor. Place sensor in the absorber's sensor sleeve (in centre of frame on
the EURO C22) and close again. Connect cables through the ventilation
tile to the sensor box.
Figure 30 Connect the collectors with corrugated stainless steel tube.
Watch out for the gaskets.
Figure 31 Apply counterforce when tightening to protect collector
connection against damage. If required use wrench to correct distorted
hose.
