Electrical connection
230/208 volt units may be plugged into a receptacle. 265 volt units are provided
with a junction box and require direct
C connection. (NEC Requires 265V Direct
Connection.) See Architects and Engineers Design Data Manual for electrical connection information including use of
must comply with local electrical codes and regulations.
Ducted applications
2900 and 3900 series can be used with ductwork to heat or cool more than one room. RAK6052 Duct Adapter is applied to top of case over air discharge. RAK601 Duct Extension is applied to right or left of adapter.
Locally fabricated ductwork may be added to extend to maximum recommended distance of 15 feet.
For additional information on ducted applications, including special adapters for replacement units, refer to Architects and Engineers Design Data Manual.
