PIPING CONNECTIONS
Install the pipe chase before the piping
is connected. Do not remove the bot-
tom panel in the pipe chase.
When extended piping is present inside the AHU, the
field provided and installed insulation is required.
Whenever possible, the piping should be brought down
through outdoor AHUs within the pipe chase as shown
in

Figure 144 -
Pipe Chase Enclosure
Usable working clearance is approxi-
mately the depth of the pipe chase.
All dimensions are approximate and
are not certified for construction. For
outdoor AHUs, the drain connection
is always on the opposite side of the
pipe chase.
Penetrations through pipe chase floor must be flashed
and sealed. Penetrations through panels must be
sealed. Refer to the service manual for more informa-
tion.
Where piping is insulated, insulation should not be in-
stalled until after the flashing is completed.
