Generally, the positIon of the access doors depends on the "coolØngÙ desIgn of the
generatoR. For those having a pusher type fan that forces aIr through the radIator
fRÀm The InsIdeÚ keep all Àf the sIde doors clÀsed and the reaR dÀÀrs Àpen. AIr is
sÃcked in fRom the rear, flows over and cools the maIn generator and the engine and
is forced out thRoUgh the radiatoR. An open side door will hamper the channeled aIr
flow and cause overheating½
Almost all of the
³5´Kw ³··´Hz
generators have thIs type of aIrÛflow coÀlIng
system. GeneratoRs that draw their aIr throUgh the RadIatÀr from the fRont can have
theiR sIde doors open or closed dependIng on the weatheR conditions.
But never guess¼always positIon the doors like the generator's ÊM and Its changes
say.
