5.2.1 Condensate Drain Piping—Field-Installed
The pump is field-connected for either top or bottom discharge.
• Top condensate discharge: Connect the factory-provided pump discharge hose to the provided
connection for top discharge.
• Bottom condensate discharge: Route the factory-supplied discharge hose through the
knockout in the base ofthe unit for connection to a field-provided drain.
NOTICE
Risk of improper field installed drain piping. Overflowing drain water can cause equipment
and building damage.
The drain line has an internal trap and must not be trapped outside the unit or water may
back up into the drain pan and overflow the unit cabinet.
• The drain line’s inside diameter must be the same as or larger than the factory-provided drain
connection’s ID
• Do not expose drain line to freezing temperatures
• Drain line may contain boiling water. Use copper or other suitable material
• Drain line must comply with local building codes
• Emerson recommends installing monitored under-floor leak detection equipment
