Note: This step is intended as a pre-assembly step that can be

performed off the roof.
1. Separate pieces, of the required lengths, from the fleece roll protection sheet
(MSP-FR-EW-PSF, ⑤) in the required quantity (as indicated in the PROFIS
Software report). Two different lengths may be required to match the length
of base profiles (MSP-FR-EW-BP, ③) used. The roll is divided into perforated
sections and can be easily pulled apart without the use of a knife or cutting
tool.
Figs. 4, 5 and 6: Assembly of supports to base profiles
Note: This step is intended as a pre-assembly step that can be
performed off the roof. There may be two lengths of base profiles
(MSP-FR-EW-BP, ③) and the correct number of each match of
support type, whether high support (MSP-FR-EW-SH, ① ) and low
support (MSP-FR-EW-SL, ②), to lengths of (base profiles (MSP-
FR-EW-BP, ③) is indicated in the software report.
1. Click into place the high supports (MSP-FR-EW-SH, ① ) into the base
profiles (MSP-FR-EW-BP, ③). The supports should be approximately

Note: This step is intended as a pre-assembly step that can be
performed off the roof.
1. Position the screws (MSP-FR-S, ⑩) into the connection channels (MSP-FR-
EW-C, ④) in the correct hole. The correct hole is indicated in the software
report. Note: there are two lengths of connection channels and each length
may require the use of different holes. Additionally, the holes at each end
Figs. 8a and 8b: Layout components on roof and measure out starting point
1. The components should be laid out so as to avoid concentrated loads on
the roof, and appropriately to enable easy and quick installation. Note: short
connection channels (MSP-FR-EW-C, ④) run in the east-west direction and
longer connection channels run in the north-south direction. If two lengths of
base profiles (MSP-FR-EW-BP, ③) are being used, the shorter ones will be
placed around the edges of blocks while the longer length base profiles will
Figs. 9 and 10: Assemble connection channels
Note: No loose screws (MSP-FR-S, ⑩) will be needed on the roof since
they are all preassembled in the preceding steps.
1. Fix the shorter connection channels (MSP-FR-EW-C, ④) (running in the
east-west direction) to the sides of the high supports (MSP-FR-EW-SH, ①)
and low supports (MSP-FR-EW-SL, ②), tightening the pre-assembled screws
with a torque of 10 Nm. The connection channels (MSP-FR-EW-C, ④) can
be fixed either side of the supports and in either direction.
Fig. 11: Installation of additional layer of protection sheet
Note: this step is only required for roofs with a bitumen or EPDM roof
covering. The software report will indicate if this step is necessary.
1. Under each base profile (MSP-FR-EW-BP, ③), position a second protection
sheet piece (MSP-FR-EW-PSF, ⑤) of equal length to the protection sheet
fixed to the base profile, so that it sticks down onto the roof surface. Subse-
Figs. 12a, 12b and 13: Position ballast
Note: Ballast is not needed for every project. This step is only necessary
if the software report indicates that ballast is needed. If ballast is
required, it is very important to ensure the correct amount of ballast

1. Make sure the PROFIS report is available on site and that those commissi-
oned with the work are fully familiar with the design layout.
2. Peal off the plastic sheeting from fleece (MSP-FR-EW-PSF, ⑤) in order to
exposure the sticky stripes
3. Ensure the sticky stripes are facing upwards and lower the base profiles
(MSP-FR-EW-BP, ③) into place. The base profiles should be positioned so
as no edges extend beyond the outer edge of the protection sheet (MSP-FR-
EW-PSF, ⑤). There should be an approximate 10mm width of protection
sheet extending beyond all edges of the base profiles.
centrally located within the base profiles, and must not overhang from the
edge. They should not be screwed into place at this time.
2. Click into place the low supports (MSP-FR-EW-SL, ②) into the base profiles
(MSP-FR-EW-BP, ③). The supports should be approximately centrally
located within the base profiles, and must not overhang from the edge.
3. Screw the low support (MSP-FR-EW-SL, ②) into place using a screw (MSP-
FR-S, ⑩) with a torque of 10Nm. Only one screw is needed per support.
may differ by a space of one. The connection channels are symmetrical in
design, so it does not matter which end each hole position is used.
2. When positioned in place the screws (MSP-FR-S, ⑩) should extrude appro-
ximately 2-5 mm through the underside of the connection channels (MSP-FR-
EW-C, ④).
be used in the block centers.
2. Following the details in the software report, measure out the position of the
starting lower support (MSP-FR-EW-SL, ②) and place it appropriately. Note:
ensure the correct base profile (MSP-FR-EW-BP, ③) length is used (it will be
the shorter one if two lengths are being used).
2. Fix the longer connection channels (MSP-FR-EW-C,④) (running in the south-
north direction) within the high supports (MSP-FR-EW-SH, ① ) so that the
support is also screwed onto the base profile (MSP-FR-EW-BP, ③), tighte-
ning the pre-assembled screws with a torque of 10 Nm. Always use the hole
nearest the edge of the high support for each connection channel.
Note: If any walking paths have been selected for the layout, refer to the
software report to ensure correct placement (location and channel
length) for the walking path inclusion.
quently, the two layers of protection sheets will be in contact with each other
one-to-one.
2. If the base profile (MSP-FR-EW-BP, ③) is positioned over an overlap of
membrane layers, ensure the protection sheet (MSP-FR-EW-PSF, ⑤) is level
by providing additional layers of protection sheet as appropriate.
is positioned in the correct locations. The ballast stones are not
supplied by Hilti.
