From the Electronic Forum:
It was a matter... made the solder for 4 jobs. places and put the channel extraction... as I was assured by the manager of the installation company - it is the weakest channel "ventilator"... In general, they mounted, left... placed the tables, disassembled... rubbed... all papers and light objects disappeared from the tables))))) good sho in this channel is a grid and filters in front of the engine )))) opened the look-abandoned ))))) then the regulator put ))) and there was a case with this extraction )) the rushed from the basement to us. I swallowed my own moves... once in the morning I entered the workshop - he sits and eats a pencil of passes! This is infection! And just next to the outlet... well... I didn’t stand up and clicked on the switch... Passages didn’t slip into the pipe but the hood, shaking its bones over the pipe, teleported into the grid of the motor... there was no chance of surviving, unfortunately... so here... the fans are wildly different.
