Water/Glycol-cooledandChilled-waterPipingApplications
The following pipe connections are required:
• A drain line from the evaporator coil drain pan.
• A drain line from the secondary drain pan (if applicable).
• A water-supply line to the optional humidifier (if applicable).
• On air-cooled systems: refrigerant piping connections between the Liebert PDX and the
condenser. See Refrigerant Piping and Charging on page34.
• On chilled-water systems: connections to the building chilled-water source.
• On water-glycol systems: connections to a water or glycol loop.
5.1.1 Field-installed, Gravity-fed Drain Line Requirements
NOTICE
Risk of water backing up in the drain line. Leaking and overflowing water can cause equipment
and building damage.
Do not install an external trap in the drain line. This line already has a factory-installed trap
inside the cabinet. Installation of a second trap will prevent drain-water flow and will cause the
water to overflow the drain pan.
This line may contain boiling water. Use copper or other material that is rated for handling
boiling water for the drain line. Sagging condensate drain lines may inadvertently create an
external trap.
