Trane products are identified by a
multiple character model number that
precisely identifies a particular type of
unit. Following is an explanation of the
model number code used to identify
the Electric Unit Heater. It will enable
the owner or Service engineer to
define operation, components and
accessories.
Important! Be sure to reference the
model and serial numbers (when
present) printed on the panel
nameplate label when ordering
replacement parts or requesting
service.
