Condition
: Parallel connection
▶
To avoid pressure losses in the sub-collector fields, only
use parallel connection for collector rows with the same
number of collectors.
▶
Ensure that each sub-collector field has the same total
pipe length in the flow and return (Tichelmann system), in
order to avoid pressure losses in the connection pipes.
4.1.7
Preparing the roof duct
Condition
: On-roof installation
Caution.
Building damage due to penetrating wa-
ter.
If the roof duct is not prepared properly, wa-
ter may penetrate the building interior.
▶
Ensure that the roof duct is prepared
properly.
▶
Make a v-shaped cut in the roofing felt membrane.
▶
Fold the upper, wider flap onto the roof batten above,
and fold the lower, narrower flap onto the roof batten
below.
▶
Fix the roofing felt membrane tight to the roof batten, so
that any moisture runs off to the side.
Condition
: Flat-roof installation
Caution.
Lack of tightness due to destruction of
the roof skin.
In the event of destruction of the roof skin,
water may penetrate the building.
▶
Ensure adequate protection of the roof
skin during installation on roof sealing
surfaces.
▶
Place large-area building protection mats
underneath the installation system.
▶
After installation, check the tightness of
the building shell where there are directly
connected racks.
▶
Commission a roofer to prepare the roof duct.
