6 PIPING REQUIREMENTS
The fluid connections to the unit are threaded and sealed with threaded plugs. Connections are provided at the top and
bottom of the unit.
• 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 arranged so that it offers the least resistance . Careful planning of
the piping layout under the raised floor is required. When installing piping on the sub-floor, we recommend
installing the pipes in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes
should be run parallel.
• Place the tubing on supporting saddles.
• Install shut-off ball valves on the inlet and outlet pipes to ease maintenance.
• Install optional thermostats and pressure gauges on the inlet and outlet pipes.
• Install a water drain tap at the lowest point in the circuit.
• Locate air vents at tops of all risers and any intermediate system high points.
