Install Manual

Introduction
2
・Roof Tech recommends a thermal splice ( a gap between rails) every 14 Ft., however, it
must be determined by the installer based on the rail system installation instructions.
The installer must also determine the maximum allowed span and cantilever design
parameters recommended by the rail system manufacturer. The RT-MINI Ⅱ can be
installed on low slope roofs (Metal, EPDM, TPO, SBS Modified Bitumen/Torch-on,
Asphalt) and steep slope roofs (Asphalt shingles, Metal). For low slope roofs, make sure
there is positive drainage. RT Butyl is also compatible with felt and synthetic
underlayments.
Periodical Inspection
Roof Tech Inc. recommends inspecting installed racking system periodically for loose
components, loose fasteners and any corrosion. If found, those components are to be re-
tightened, or replaced immediately. When a PV module needs to be removed from the PV
array for maintenance and/or replacement, the electric bonding system may need to be
temporarily restored to maintain the electrical bonding path. Please make sure the system
electrical circuits and disconnects are in the open position and the entire system is powered
down. Cover the fronts of modules in the array with an opaque material to stop the
production of electricity. Use appropriate safety equipment such as insulated tools and
insulating gloves to protect yourself.
Maintenance of the PV modules should be carried out by licensed contractors, according to
the PV manufacturer’s installation/maintenance instructions and Roof Tech’s installation
instructions.
Maintenance should not be conducted under a wet and/or high wind conditions.
