System working fine. Occupants very happy to have system.
All system piping is well insulated.
Exterior insulation is well protected with foil type material.
Flat roof. There was evidence of water damage on utility room ceiling where the ICS feed and return lines penetrate the ceiling. Client stated that these were there before the solar system was installed. Had roof repaired prior to solar installation. Solar system roof flashing is well done. No leaks from solar system.
