Herman Nelson Fan Coil Unit Data

Pepper

I am working on a new boiler project for a town hall in New England.  The building has sixteen Herman Nelson fan coil units for heating. 



The unit has the following nameplate data:



NelsonAir



Model Number:  LSGDRXR2224-102

Or:  LSGDRXRZ224-102   (the first 2 could be a Z)



I'm trying to get gpms, cfms, and other capacity information for this unit.  Two approaches to McQuay have yielded no data, since this is an old (1974) unit. 



Does anyone have an old McQuay fan coil unit catalog that has information about this unit?



Thank you.
