SPACEPAK SYSTEM DESIGN
The SpacePak WCSP-D unit is a hydronic fan coil unit
which utilizes chilled or heated water from a chiller or
boiler to provide the conditioned air through the specially
designed prefabricated preinsulated flexible duct system.
The system and its basic components operate the same
as in any conventional air-to-air cooling system.
The SpacePak system is covered by the following U.S.

Patents: 891,292; 923,935; 923,936.
CODE COMPLIANCE
Fan coil unit installation must conform to the require-
ments of the local authority having jurisdiction or, in
the absence of such requirements, to the National Board
of Fire Underwriters regulations. Fan coil unit meets
ETL listing requirements.
All electrical wiring must be in accordance with
the National Electrical Code ANSI/NFPA No. 70-latest
