When installing a pipe system in air-conditioning ducts, the following must be observed:
–
Since the FCS-320-TM and the pipe system are located in different pressure ranges, an
air return pipe (see
Figure 3.18
) must be provided.
–
The pipe entries into the duct must be airtight.
–
The portion of the pipe system that is outside the duct must be sealed airtight.
