Installation

2.5Piping Considerations

Consideration should be given before installing refrigerant and liquid lines next to, under or above electronic equipment.

2.5.1Drain Line

A 3/4" (19.1 mm) female pipe thread (FPT) connection is provided for the evaporator coil condensate drain. This drain line also drains the humidifier, if applicable. The drain line must be located so it will not be exposed to freezing temperatures. The drain should be at least the full size of the drain connec- tion and pitched a minimum of 1/8" per ft. (11 mm per meter).

NOTE

This line may contain boiling water. Select appropriate drain system materials.

The Challenger ITR comes standard with a condensate pump will require a field-supplied trap downstream from the pump. The drain line must comply with all applicable codes.
