6.1Piping Considerations

Manual shut-off valves should be installed at the supply and return lines to each unit. This will pro- vide for routine service and emergency isolation of the unit.

Consideration of the minimum water temperature to be supplied from the chiller will determine if the need exists to insulate supply and return lines. Insulation will prevent condensation on the supply and return lines.

To provide for the emergency of water leaks and the consequences of sub-floor flooding, floor drains should be provided with wet traps or a water detection system, such as a Liqui-tect, that is installed near the base of the unit or below the elevated floor.
