Place the required ballast in accordance to the
ballast planning inside or on top of the base troughs
after installing the modules. The required ballast
depends on the system area and is specified in the
ballast plan in kg and/or number of stones. The
ballast can be laid out under, in front of or behind
the module to place all the required ballast. The
selection of the ballast stone is up to the customer,
the dimensions are to be adapted to the weight of
the ballast indicated at each point.
For ballast installations using large amounts of
ballast, ballast troughs (MV 9) or additional base
troughs under the module are recommended
(MV 5).
Guide the wind deflector over the round part of the
module supports and place it on the base trough.
Install the adjacent wind deflector for the following
module with an overlap of at least 150 mm to the
first wind deflector.
Secure the wind deflectors to the base troughs with
two screws for each base trough and to the round
part of the module support with one screw.
The screw must not be overtightened!
Alternatively, the first base trough at the system
edge / expansion joint must be installed flush with
the modules, the subsequent troughs must be
positioned centrally beneath the module joint.
Prerequisite:
Flat roof end clamp (MV 2)
