Periodical Inspection

Tools Required for Assembly

・Roof Tech recommends a thermal splice 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 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.

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.
