50 Installation manual auroTHERM exclusive 0020077994_02

Placing load weights on load plates

▶ Transport the required number of loading weights to

the flat roof.

▶ Place the load weights on the load plates as shown

above.

▶ Ensure that the distance between the loading weights

and the racks is as small as possible.

Danger!

Risk of death due to inadequate fasten-

ing of the load weights onto the load

plates!

If the load weights are inadequately se-

cured on the load plates, collectors could

fall from the roof and cause life-threaten-

ing accidents.

▶ Secure all load weights on the load

plates adequately against slipping and

tilting.

▶ Distribute the load weights evenly over the load plates.

Conditions: Type of installation: Floating installation (without load plates)

Preparing weights

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, non-slip building pro-

tection mats underneath the installation

system.

▶ If the roof is covered with gravel, remove the gravel at

the places where you wish to position the weights, and

use non-slip building protection mats to protect the roof

skin.

▶ Define the required rack clearances as described in the

chapter "Defining rack clearances".

Note

For each rack, you need two equal weights.

For the first collector, you therefore need

four weights. For each additional collector,

you will need an additional rack.

▶ Transport the required number of weights to the flat

roof.

▶ Lay the weights in the final positions of the installation

site.

Note

The four weights for holding two racks for

a collector are very heavy. Therefore, it is

advisable to determine the final position and

orientation of the weights before screwing

on the rack and laying the weights there.

▶ Select a suitable fastening material for the weights used

(diameter: at least 10 mm).

▶ Drill a hole into the centre of each weight.
