Piping And Refrigerant Requirements - Liebert PX018 Installer's/User's Manual

5 PIPING AND REFRIGERANT REQUIREMENTS

All fluid and refrigeration 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.
