Mounting instructions – MSP-FR-EW flat roof PV mounting system
− Sufficient structural capacity for the additional loads arising from the PV installation.
− Consideration of the permissible bearing pressure capacity of the insulation material.
− Compatibility and condition of the roofing membrane.
− Adequate water drainage and lack of water pooling.
− Condition of the roof (free from damage).
Prior to initiating the PV system installation, the roof must be:
− Brought to the minimal standards required.
− Thoroughly cleaned, with all dirt and debris removed.
− Free from snow and ice.
The customer must verify that the installing conditions required for MSP-FR-EW are satisfied. Ensure those
commissioned with the work are fully familiar with the design layout created. Distribute the material evenly on
the roof so as not to create concentrated loading. Make sure the required tools are available (a torque
wrench, battery powered screwdriver and a size 30 Torx attachment).
Installation
Fig. 1: proMSP software report
Note:
The proMSP software report is created once the PV system has been designed using Schweizer
proMSP software.
1. Make sure the proMSP report is available on site and that those commissioned with the work are fully fa-
miliar with the design layout.
Figs. 2 and 3: Assembly of protection sheets to base profiles
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,
) in the
required quantity (as indicated in the proMSP software report). Two different lengths may be required to
match the length of base profiles (MSP-FR-EW-BP,
) used. The roll is divided into perforated sections
and can be easily pulled apart without the use of a knife or cutting tool.
2. Peal off the plastic sheeting from fleece (MSP-FR-EW-PSF,
) in order to exposure the sticky stripes
3. Ensure the sticky stripes are facing upwards and lower the base profiles (MSP-FR-EW-BP,
) 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,
). There should be an approximate 10 mm width of protection sheet extending
beyond all edges of the base profiles.
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,
) and the correct number of each match of support type, whether
high support (MSP-FR-EW-SH,
) and low support (MSP-FR-EW-SL,
), to lengths of (base profiles (MSP-
FR-EW-BP,
) is indicated in the software report.
1. Click into place the high supports (MSP-FR-EW-SH,
) into the base profiles (MSP-FR-EW-BP,
). The
supports should be approximately 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,
) into the base profiles (MSP-FR-EW-BP,
). 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,
) into place using a screw (MSP-FR-S,
) with a torque of
10 Nm. Only one screw is needed per support.
