4 PIPING REQUIREMENTS

All fluid connections to the unit, with the exception of the condensate drain, are sweat copper. Factory-installed piping
brackets must not be removed. Field-installed piping must be installed in accordance with local codes and must be
properly assembled, supported, isolated and insulated. Avoid piping runs through noise-sensitive areas, such as office walls
and conference rooms.
Refer to specific text and detailed diagrams in this manual for other unit-specific piping requirements.
All piping below the elevated floor must be located so that it offers the least resistance to air flow. Careful planning of the
piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the
subfloor, we recommend that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever
possible, the pipes should be run parallel to the air flow.
The pipe connection locations, piping general arrangement and schematics are described in the submittal documents
included in the Submittal Drawings
