Installation Instructions: Introduction and Overview
Ducted Product Information
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 top 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.
