Revised May 6, 2015

 

When assigning a unit model number, be certain that the assigned model number is completely valid per our ETL listing. We have had inspectors at the jobsite question our unit model numbers where it does not match what is shown in our ETL listing. If a model number is not shown in our ETL listing, it may not be used. Please note that the latest revisions to our model number sequence have accommodations for units with more than 10 compressors and units with greater than 100,000 cfm. Also, the ETL listing has been changed to allow any two letters for the last two characters of the model number. If you would like to create a new suffix, please make the request in writing to the engineering manager for approval. The suffix MUST be approved before it can be used. The current suffixes approved for use are:

 

Condensing Unit CU

Desiccant Cooling DC

Desiccant Dehumidification DD

Desiccant Dehumidification w/Heat Pipe DH

Energy Recovery Heat Pipe EH

Energy Recovery Plate Heat Exchanger EP

Energy Wheel EW

Hot Gas Reheat & Subcool Coil GC

Hot Gas Reheat Coil HG

Heat Reclaim & Heat Pipe HH

Heat Pipe HP

Reclaim Coil (or space for) HR
