Liebert PW017 User Manual

Observe the following requirements and refer to Figure 5.1 on the next page, when installing and routing
the drain line:
• The drain line must be sized for 2 gpm (7.6 l/m) flow.
• The drain line must be located so it will not be exposed to freezing temperatures.
• The drain should be the full size of the drain connection.
• The drain line must slope continuously away from the unit. Pitch drain line toward drain a
minimum of 1/8in. (3mm) per 1ft (305mm) of length.
• Drain is trapped internally. Do not externally-trap the drain line.
• The drain line must be rigid enough that it does not sag between supports, which
unintentionally creates traps.
• Use copper or other material suitable for draining water that can reach temperatures up to
212°F (100°C).
• The drain line must comply with all applicable codes.
• When the evaporator is installed below the level of the gravity-fed drain line, the optional
condensate pump kit is required. See the appropriate section, depending on the configuration
of your unit:
• Factory-installed CondensatePump in UpflowUnits on page33
• Field-installed Condensate Pump for Downflow Units on page33
