How to install 45° elbows
Accy. No.: 303 911
Example:
An offset of 400 mm is measured.
This value is then used, along with the
table below, to determine the length
of the air conduit (= 284 mm) and the
height (= 420 mm).
Important:
This gives a corresponding
exhaust-conduit length of
284 + 40 = 324 mm.
