Installation

2.5Piping Considerations

All piping below the elevated floor must be located so that it offers the least resistance to air flow. Careful planning of the piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the subfloor, it is recommended that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes should be run parallel to the air flow.

Condensate pumps for downflow units are shipped separately to be field-installed under the raised floor. Pump height is 11 inches (279 mm).

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 drain line must include one and only one trap. Units without a condensate pump have a factory-supplied trap in the unit, so a field trap should not be added. Units with a condensate pump will require a field-supplied trap downstream from the pump. The drain line must comply with all applicable codes.
