Installation Instructions: Introduction and Overview
Ducted Product Information
Parts Included
The Ducted unit will install above the ceiling or in a
soffit area. It is mounted using threaded rods that fit
into brackets that are located at all four corners of the
cabinet.
Each unit has a built-in condensate pump and a
float switch to avoid an overflow situation and to
maintain reliable operation. An insulated condensate
fitting is included in the accessory pouch. This fitting
connects the condensate drain outlet of the unit to the
field-supplied drain piping.
When making refrigerant line connections, always use
the flare nuts provided with this equipment. Refrigerant
line connections should be wrapped with insulating tape
at the unit to prevent sweating.
